May contain more technical jargon than usual. Introduction I recently watched Eliezer Yudkowsky's appearance on the Bankless podcast, where he argued that AI was nigh-certain to end humanity. Since the podcast, some commentators have offered pushback against the doom conclusion. However, one sentiment I saw was that optimists tended not to engage with the specific arguments pessimists like Yudkowsky offered. Economist Robin Hanson points out that this pattern is very common for small groups which hold counterintuitive beliefs: insiders develop their own internal language, which skeptical outsiders usually don't bother to learn. Outsiders then make objections that focus on broad arguments against the belief's plausibility, rather than objections that focus on specific insider arguments. As an AI "alignment insider" whose current estimate of doom is around 5%, I wrote this post to explain some of my many objections to Yudkowsky's specific arguments. I've split this post into chronologically ordered segments of the podcast in which Yudkowsky makes one or more claims with which I particularly disagree. All bulleted points correspond to specific claims by Yudkowsky, and I follow each bullet point with text that explains my objections to the claims in question. I have my own view of alignment research: shard theory, which focuses on understanding how human values form, and on how we might guide a similar process of value formation in AI systems. I think that human value formation is not that complex, and does not rely on principles very different from those which underlie the current deep learning paradigm. Most of the arguments you're about to see from me are less: I think I know of a fundamentally new paradigm that can fix the issues Yudkowsky is pointing at. and more: Here's why I don't agree with Yudkowsky's arguments that alignment is impossible in the current paradigm. My objections Will current approaches scale to AGI? * Yudkowsky apparently thinks not, and that the techniques driving current state of the art advances, by which I think he means the mix of generative pretraining + small amounts of reinforcement learning such as with ChatGPT, aren't reliable enough for significant economic contributions. However, he also thinks that the current influx of money might stumble upon something that does work really well, which will end the world shortly thereafter. I'm a lot more bullish on the current paradigm. People have tried lots and lots of approaches to getting good performance out of computers, including lots of "scary seeming" approaches such as: 1. Meta-learning over training processes. I.e., using gradient descent over learning curves, directly optimizing neural networks to learn more quickly. 2. Teaching neural networks to directly modify themselves by giving them edit access to their own weights. 3. Training learned optimizers - neural networks that learn to optimize other neural networks - and having those learned optimizers optimize themselves. 4. Using program search to find more efficient optimizers. 5. Using simulated evolution to find more efficient architectures. 6. Using efficient second-order corrections to gradient descent's approximate optimization process. 7. Tried applying biologically plausible optimization algorithms inspired by biological neurons to training neural networks. 8. Adding learned internal optimizers (different from the ones hypothesized in Risks from Learned Optimization) as neural network layers. 9. Having language models rewrite their own training data, and improve the quality of that training data, to make themselves better at a given task. 10. Having language models devise their own programming curriculum, and learn to program better with self-driven practice. 11. Mixing reinforcement learning with model-driven, recursive re-writing of future training data. Mostly, these don't work very well. The current capabilities paradigm is state of the art because it gives the best results of anything we've tried so far, despite lots of effort to find better paradigms. When capabilities advances do work, they typically integrate well with the current alignment^[1] and capabilities paradigms. E.g., I expect that we can apply current alignment techniques such as reinforcement learning from human feedback (RLHF) to evolved architectures. Similarly, I expect we can use a learned optimizer to train a network on gradients from RLHF. In fact, the eleventh example is actually ConstitutionalAI from Anthropic, which arguably represents the current state of the art in language model alignment techniques! This doesn't mean there are no issues with interfacing between new capabilities advances and current alignment techniques. E.g., if we'd initially trained the learned optimizer on gradients from supervised learning, we might need to finetune the learned optimizer to make it work well with RLHF gradients, which I expect would follow a somewhat different distribution from the supervised gradients we'd trained the optimizer on. However, I think such issues largely fall under "ordinary engineering challenges", not "we made too many capabilities advances, and now all our alignment techniques are totally useless". I expect future capabilities advances to follow a similar pattern as past capabilities advances, and not completely break the existing alignment techniques. Finally, I'd note that, despite these various clever capabilities approaches, progress towards general AI seems pretty smooth to me (fast, but smooth). GPT-3 was announced almost three years ago, and large language models have gotten steadily better since then. Discussion of human generality * Yudkowsky says humans aren't fully general: "If humans were fully general, we'd be as good at coding as we are at football, throwing things, or running. Some of us are okay at programming, but we're not spec'd for it. We're not fully general minds." Evolution did not give humans specific cognitive capabilities, such that we should now consider ourselves to be particularly well-tuned for tasks similar to those that were important for survival in the ancestral environment. Evolution gave us a learning process, and then biased that learning process towards acquiring capabilities that were important for survival in the ancestral environment. This is important, because the most powerful and scalable learning processes are also simple and general. The transformer architecture was originally developed specifically for language modeling. However, it turns out that the same architecture, with almost no additional modifications, can learn image recognition, navigate game environments, process audio, and so on. I do not believe we should describe the transformer architecture as being "specialized" to language modeling, despite it having been found by an 'architecture search process' that was optimizing for performance on language modeling objectives. Thus, I'm dubious of the inference from: Evolution found a learning process searching for architectures that did well on problems in the ancestral environment. to: In the modern environment, you should think of the human learning process, and the capabilities it learns, as being much more specialized to problems like those in the ancestral environment, as compared to those problems of the modern environment. There are of course, possible modifications one could make to the human brain that would make humans better coders. However, time and again, we've found that deep learning systems improve more through scaling, of either the data or the model. Additionally, the main architectural difference between human and other primate brains is likely scale, and not e.g., the relative sizes of different regions or maturation trajectories. See also: The Brain as a Universal Learning Machine and Brain Efficiency: Much More than You Wanted to Know * Yudkowsky talks about an AI being more general than humans: "You can imagine something that's more general than a human, and if it runs into something unfamiliar, it's like 'okay, let me just go reprogram myself a bit, and then I'll be as adapted to this thing as I am to - you know - anything else." I think powerful cognition mostly comes from simple learning processes applied to complex data. Humans are actually pretty good at "reprogramming" themselves. We might not be able to change our learning process much^[2], but we can change our training data quite a lot. E.g., if you run into something unfamiliar, you can read a book about the thing, talk to other people about it, run experiments to gather thing-specific data, etc. All of these are ways of deliberately modifying your own cognition to make you more capable in this new domain. Additionally, the fact that techniques such as sensory substitution work in humans, or the fact that losing a given sense causes the brain to repurpose regions associated with that sense, suggest we're not that constrained by our architecture, either. Again: most of what separates a vision transformer from a language model is the data they're trained on. How to think about superintelligence * Yudkowsky describes superintelligence: "A superintelligence is something that can beat any human, and the entire human civilization, at all the cognitive tasks." This seems like way too high a bar. It seems clear that you can have transformative or risky AI systems that are still worse than humans at some tasks. This seems like the most likely outcome to me. Current AIs have huge deficits in odd places. For example, GPT-4 may beat most humans on a variety of challenging exams (page 5 of the GPT-4 paper), but still can't reliably count the number of words in a sentence. Compared to Yudkowsky, I think I expect AI capabilities to increase more smoothly with time, though not necessarily more slowly. I don't expect a sudden jump where AIs go from being better at some tasks and worse at others, to being universally better at all tasks. The difficulty of alignment * Yudkowsky: "the space of minds is VERY wide. All the human are in - imagine like this giant sphere, and all the humans are in this like one tiny corner of the sphere. And you know we're all like basically the same make and model of car, running the same brand of engine. We're just all painted slightly different colors." I think this is extremely misleading. Firstly, real-world data in high dimensions basically never look like spheres. Such data almost always cluster in extremely compact manifolds, whose internal volume is minuscule compared to the full volume of the space they're embedded in. If you could visualize the full embedding space of such data, it might look somewhat like an extremely sparse "hairball" of many thin strands, interwoven in complex and twisty patterns, with even thinner "fuzz" coming off the strands in even more-complex fractle-like patterns, but with vast gulfs of empty space between the strands. In math-speak, high dimensional data manifolds almost always have vastly smaller intrinsic dimension than the spaces in which they're embedded. This includes the data manifolds for both of: 1. The distribution of powerful intelligences that arise in universes similar to ours. 2. The distribution of powerful intelligences that we could build in the near future. As a consequence, it's a bad idea to use "the size of mind space" as an intuition pump for "how similar are things from two different parts of mind space"? The manifold of possible mind designs for powerful, near-future intelligences is surprisingly small. The manifold of learning processes that can build powerful minds in real world conditions is vastly smaller than that. It's no coincidence that state of the art AI learning processes and the human brain both operate on similar principles: an environmental model mostly trained with self-supervised prediction, combined with a relatively small amount of reinforcement learning to direct cognition in useful ways. In fact, alignment researchers recently narrowed this gap even further by applying reinforcement learning^[3] throughout the training process, rather than just doing RLHF at the end, as with current practice. The researchers behind such developments, by and large, were not trying to replicate the brain. They were just searching for learning processes that do well at language. It turns out that there aren't many such processes, and in this case, both evolution and human research converged to very similar solutions. And once you condition on a particular learning process and data distribution, there aren't that many more degrees of freedom in the resulting mind design. To illustrate: 1. Relative representations enable zero-shot latent space communication shows we can stitch together models produced by different training runs of the same (or even just similar) architectures / data distributions. 2. Low Dimensional Trajectory Hypothesis is True: DNNs Can Be Trained in Tiny Subspaces shows we can train an ImageNet classifier while training only 40 parameters out of an architecture that has nearly 30 million total parameters. Both of these imply low variation in cross-model internal representations, given similar training setups. The technique in the Low Dimensional Trajectory Hypothesis paper would produce a manifold of possible "minds" with an intrinsic dimension of 40 or less, despite operating in a ~30 million dimensional space. Of course, the standard practice of training all network parameters at once is much less restricting, but I still expect realistic training processes to produce manifolds whose intrinsic dimension is tiny, compared to the full dimension of mind space itself, as this paper suggests. Finally, the number of data distributions that we could use to train powerful AIs in the near future is also quite limited. Mostly, such data distributions come from human text, and mostly from the Common Crawl specifically, combined with various different ways to curate or augment that text. This drives trained AIs to be even more similar to humans than you'd expect from the commonalities in learning processes alone. So the true volume of the manifold of possible future mind designs is vaguely proportional to: (N distinct learning processes)x(N data distributions)x(cross-run variation) The manifold of mind designs is thus: 1. Vastly more compact than mind design space itself. 2. More similar to humans than you'd expect. 3. Less differentiated by learning process detail (architecture, optimizer, etc), as compared to data content, since learning processes are much simpler than data. (Point 3 also implies that human minds are spread much more broadly in the manifold of future mind than you'd expect, since our training data / life experiences are actually pretty diverse, and most training processes for powerful AIs would draw much of their data from humans.) As a consequence of the above, a 2-D projection of mind space would look less like this: [gh1ldoowhp]Humans in blue, AIs in red and more like this: [g29xuo9zkb]Humans in blue, AIs in red * Yudkowsky brings up strawberry alignment: "I mean, I wouldn't say that it's difficult to align an AI with our basic notions of morality. I'd say that it's difficult to align an AI on a task like 'take this strawberry, and make me another strawberry that's identical to this strawberry down to the cellular level, but not necessarily the atomic level'. So it looks the same under like a standard optical microscope, but maybe not a scanning electron microscope. Do that. Don't destroy the world as a side effect." My first objection is: human value formation doesn't work like this. There's no way to raise a human such that their value system cleanly revolves around the one single goal of duplicating a strawberry, and nothing else. By asking for a method of forming values which would permit such a narrow specification of end goals, you're asking for a value formation process that's fundamentally different from the one humans use. There's no guarantee that such a thing even exists, and implicitly aiming to avoid the one value formation process we know is compatible with our own values seems like a terrible idea. It also assumes that the orthogonality thesis should hold in respect to alignment techniques - that such techniques should be equally capable of aligning models to any possible objective. This seems clearly false in the case of deep learning, where progress on instilling any particular behavioral tendencies in models roughly follows the amount of available data that demonstrate said behavioral tendency. It's thus vastly easier to align models to goals where we have many examples of people executing said goals. As it so happens, we have roughly zero examples of people performing the "duplicate this strawberry" task, but many more examples of e.g., humans acting in accordance with human values, ML / alignment research papers, chatbots acting as helpful, honest and harmless assistants, people providing oversight to AI models, etc. See also: this discussion. Probably, the best way to tackle "strawberry alignment" is to train the AI with a mix of other, broader, objectives with more available data, like "following human instructions", "doing scientific research" or "avoid disrupting stuff", then trying to compose many steps of human-supervised, largely automated scientific research towards the problem of strawberry duplication. However, this wouldn't be an example of strawberry alignment, but of general alignment, which had been directed towards the strawberry problem. Such an AI would have many values beyond strawberry duplication. Related: Alex Turner objects to this sort of problem decomposition because it doesn't actually seem to make the problem any easier. Also related: the best poem-writing AIs are general-purpose language models that have been directed towards writing poems. I also don't think we want alignment techniques that are equally useful for all goals. E.g., we don't want alignment techniques that would let you easily turn a language model into an agent monomaniacally obsessed with paperclip production. * Yudkowsky argues that we can't point an AI's learned cognitive faculties in any particular direction because the "hill-climbing paradigm" is incapable of meaningfully interfacing with the inner values of the intelligences it creates. Evolution is his central example in this regard, since evolution failed to direct our cognitive faculties towards inclusive genetic fitness, the single objective it was optimizing us for. This is an argument he makes quite often, here and elsewhere, and I think it's completely wrong. I think that analogies to evolution tell us roughly nothing about the difficulty of alignment in machine learning. I have a post explaining as much, as well as a comment summarizing the key point: Evolution can only optimize over our learning process and reward circuitry, not directly over our values or cognition. Moreover, robust alignment to IGF requires that you even have a concept of IGF in the first place. Ancestral humans never developed such a concept, so it was never useful for evolution to select for reward circuitry that would cause humans to form values around the IGF concept. It would be an enormous coincidence if the reward circuitry that lead us to form values around those IGF-promoting concepts that are learnable in the ancestral environment were to also lead us to form values around IGF itself once it became learnable in the modern environment, despite the reward circuitry not having been optimized for that purpose at all. That would be like successfully directing a plane to land at a particular airport while only being able to influence the geometry of the plane's fuselage at takeoff, without even knowing where to find the airport in question. [Gradient descent] is different in that it directly optimizes over values / cognition, and that AIs will presumably have a conception of human values during training. * Yudkowsky brings up humans liking ice cream as an example of values misgeneralization caused by the shift to our modern environment: "Ice cream didn't exist in the natural environment, the ancestral environment, the environment of evolutionary adeptedness. There was nothing with that much sugar, salt, fat combined together as ice cream. We are not built to want ice cream. We were built to want strawberries, honey, a gazelle that you killed and cooked [...] We evolved to want those things, but then ice cream comes along, and it fits those taste buds better than anything that existed in the environment that we were optimized over." This example nicely illustrates my previous point. It also illustrates the importance of thinking mechanistically, and not allegorically. I think it's straightforward to explain why humans "misgeneralized" to liking ice cream. Consider: 1. Ancestral predecessors who happened to eat foods high in sugar / fat / salt tended to reproduce more. 2. => The ancestral environment selected for reward circuitry that would cause its bearers to seek out more of such food sources. 3. => Humans ended up with reward circuitry that fires in response to encountering sugar / fat / salt (though in complicated ways that depend on current satiety, emotional state, etc). 4. => Humans in the modern environment receive reward for triggering the sugar / fat / salt reward circuits. 5. => Humans who eat foods high in sugar / fat / salt thereafter become more inclined to do so again in the future. 6. => Humans who explore an environment that contains a food source high in sugar / fat / salt will acquire a tendency to navigate into situations where they eat more of the food in question. (We sometimes colloquially call these sorts of tendencies "food preferences".) 7. => It's profitable to create foods whose consumption causes humans to develop strong preferences for further consumption, since people are then willing to do things like pay you to produce more of the food in question. This leads food sellers to create highly reinforcing foods like ice cream. So, the reason humans like ice cream is because evolution created a learning process with hard-coded circuitry that assigns high rewards for eating foods like ice cream. Someone eats ice cream, hardwired reward circuits activate, and the person becomes more inclined to navigate into scenarios where they can eat ice cream in the future. I.e., they acquire a preference for ice cream. What does this mean for alignment? How do we prevent AIs from behaving badly as a result of a similar "misgeneralization"? What alignment insights does the fleshed-out mechanistic story of humans coming to like ice cream provide? As far as I can tell, the answer is: don't reward your AIs for taking bad actions. That's all it would take, because the mechanistic story above requires a specific step where the human eats ice cream and activates their reward circuits. If you stop the human from receiving reward for eating ice cream, then the human no longer becomes more inclined to navigate towards eating ice cream in the future. Note that I'm not saying this is an easy task, especially since modern RL methods often use learned reward functions whose exact contours are unknown to their creators. But from what I can tell, Yudkowsky's position is that we need an entirely new paradigm to even begin to address these sorts of failures. Take his statement from later in the interview: Oh, like you optimize for one thing on the outside and you get a different thing on the inside. Wow. That's really basic. All right. Can we even do this using gradient descent? Can you even build this thing out of giant inscrutable matrices of floating point numbers that nobody understands at all? You know, maybe we need different methodology. In contrast, I think we can explain humans' tendency to like ice cream using the standard language of reinforcement learning. It doesn't require that we adopt an entirely new paradigm before we can even get a handle on such issues. * Yudkowsky claims that evolution has a stronger simplicity bias than gradient descent: "Gradient descent by default would just like do, not quite the same thing, it's going to do a weirder thing, because natural selection has a much narrower information bottleneck. In one sense, you could say that natural selection was at an advantage, because it finds simpler solutions." On a direct comparison, I think there's no particular reason that one would be more simplicity biased than the other. If you were to train two neural networks using gradient descent and evolution, I don't have strong expectations for which would learn simpler functions. As it happens, gradient descent already has really strong simplicity biases. The complication is that Yudkowsky is not making a direct comparison. Evolution optimized over the human genome, which configures the human learning process. This introduces what he calls an "information bottleneck", limiting the amount of information that evolution can load into the human learning process to be a small fraction of the size of the genome. However, I think the bigger difference is that evolution was optimizing over the parameters of a learning process, while training a network with gradient descent optimizes over the cognition of a learned artifact. This difference probably makes it invalid to compare between the simplicity of gradient descent on networks, versus evolution on the human learning process. Yudkowsky tries to predict the inner goals of a GPT-like model. * Yudkowsky: "So a very primitive, very basic, very unreliable wild guess, but at least an informed kind of wild guess: maybe if you train a thing really hard to predict humans, then among the things that it likes are tiny, little pseudo-things that meet the definition of human, but weren't in its training data, and that are much easier to predict..." As it happens, I do not think that optimizing a network on a given objective function produces goals orientated towards maximizing that objective function. In fact, I think that this almost never happens. For example, I don't think GPTs have any sort of inner desire to predict text really well. Predicting human text is something GPTs do, not something they want to do. Relatedly, humans are very extensively optimized to predictively model their visual environment. But have you ever, even once in your life, thought anything remotely like "I really like being able to predict the near-future content of my visual field. I should just sit in a dark room to maximize my visual cortex's predictive accuracy."? Similarly, GPT models do not want to minimize their predictive loss, and they do not take creative opportunities to do so. If you tell models in a prompt that they have some influence over what texts will be included in their future training data, they do not simply choose the most easily predicted texts. They choose texts in a prompt-dependent manner, apparently playing the role of an AI / human / whatever the prompt says, which was given influence over training data. Bodies of water are highly "optimized" to minimize their gravitational potential energy. However, this is something water does , not something it wants. Water doesn't take creative opportunities to further reduce its gravitational potential, like digging out lakebeds to be deeper. Edited to add: On reflection, the above discussion overclaims a bit in regards to humans. One complication is that the brain uses internal functions of its own activity as inputs to some of its reward functions, and some of those functions may correspond or correlate with something like "visual environment predictability". Additionally, humans run an online reinforcement learning process, and human credit assignment isn't perfect. If periods of low visual predictability correlate with negative reward in the near-future, the human may begin to intrinsically dislike being in unpredictable visual environments. However, I still think that it's rare for people's values to assign much weight to their long-run visual predictive accuracy, and I think this is evidence against the hypothesis that a system trained to make lots of correct predictions will thereby intrinsically value making lots of correct predictions. Thanks to Nate Showell and DanielFilan for prompting me to think a bit more carefully about this. Why aren't other people as pessimistic as Yudkowsky? * Yudkowsky mentions the security mindset. (I didn't think the interview had good quotes for explaining Yudkowsky's concept of the security mindset, so I'll instead direct interested readers to the article he wrote about it.) As I understand it, the security mindset asserts a premise that's roughly: "The bundle of intuitions acquired from the field of computer security are good predictors for the difficulty / value of future alignment research directions." However, I don't see why this should be the case. Most domains of human endeavor aren't like computer security, as illustrated by just how counterintuitive most people find the security mindset. If security mindset were a productive frame for tackling a wide range of problems outside of security, then many more people would have experience with the mental motions necessary for maintaining security mindset. Machine learning in particular seems like its own "kind of thing", with lots of strange results that are very counterintuitive to people outside (and inside) the field. Quantum mechanics is famously not really analogous to any classical phenomena, and using analogies to "bouncing balls" or "waves" or the like will just mislead you once you try to make nontrival inferences based on your intuition about whatever classical analogy you're using. Similarly, I think that machine learning is not really like computer security, or rocket science (another analogy that Yudkowsky often uses). Some examples of things that happen in ML that don't really happen in other fields: 1. Models are internally modular by default. Swapping the positions of nearby transformer layers causes little performance degradation. Swapping a computer's hard drive for its CPU, or swapping a rocket's fuel tank for one of its stabilization fins, would lead to instant failure at best. Similarly, swapping around different steps of a cryptographic protocol will, usually make it output nonsense. At worst, it will introduce a crippling security flaw. For example, password salts are added before hashing the passwords. If you switch to adding them after, this makes salting near useless. 2. We can arithmetically edit models. We can finetune one model for many tasks individually and track how the weights change with each finetuning to get a "task vector" for each task. We can then add task vectors together to make a model that's good at multiple of the tasks at once, or we can subtract out task vectors to make the model worse at the associated tasks. Randomly adding / subtracting extra pieces to either rockets or cryptosystems is playing with the worst kind of fire, and will eventually get you hacked or exploded, respectively. 3. We can stitch different models together, without any retraining. The rough equivalent for computer security would be to have two encryption algorithms A and B, and a plaintext X. Then, midway through applying A to X, switch over to using B instead. For rocketry, it would be like building two different rockets, then trying to weld the top half of one rocket onto the bottom half of the other. 4. Things often get easier as they get bigger. Scaling models makes them learn faster, and makes them more robust. This is usually not the case in security or rocket science. 5. You can just randomly change around what you're doing in ML training, and it often works fine. E.g., you can just double the size of your model, or of your training data, or change around hyperparameters of your training process, while making literally zero other adjustments, and things usually won't explode. Rockets will literally explode if you try to randomly double the size of their fuel tanks. I don't think this sort of weirdness fits into the framework / "narrative" of any preexisting field. I think these results are like the weirdness of quantum tunneling or the double slit experiment: signs that we're dealing with a very strange domain, and we should be skeptical of importing intuitions from other domains. Additionally, there's a straightforward reason why alignment research (specifically the part of alignment that's about training AIs to have good values) is not like security: there's usually no adversarial intelligence cleverly trying to find any possible flaws in your approaches and exploit them. A computer security approach that blocks 99% of novel attacks will soon become a computer security approach that blocks ~0% of novel, once attackers adapt to the approach in question. An alignment technique that works 99% of the time to produce an AI with human compatible values is very close to a full alignment solution^[4]. If you use this technique once, gradient descent will not thereafter change its inductive biases to make your technique less effective. There's no creative intelligence that's plotting your demise^[5]. There are other areas of alignment research where adversarial intelligences do appear. For example, once you've deployed a model into the real world, some fraction of users will adversarially optimize their inputs to make your model take undesired actions. We see this with ChatGPT, whose alignment is good enough to make sure the vast majority of ordinary conversations remain on the rails OpenAI intended, but quickly fails against a clever prompter. Importantly, the adversarial optimization is coming from the users, not from the model. ChatGPT isn't trying to jailbreak itself. It doesn't systematically steer otherwise normal conversations into contexts adversarially optimized to let itself violate OpenAI's content policy. In fact, given non-adversarial inputs, ChatGPT appears to have meta-preferences against being jailbroken: [fi9kd4o6vq]I had to tune the prompt to get ChatGPT to acknowledge it might be vulnerable to adversarial attacks, but I didn't otherwise tune the prompt to make ChatGPT give a more disapproving response. GPT-4 gives a cleaner answer: [f2ujka1rqr] It cannot be the case that successful value alignment requires perfect adversarial robustness. For example, humans are not perfectly robust. I claim that for any human, no matter how moral, there exist adversarial sensory inputs that would cause them to act badly. Such inputs might involve extreme pain, starvation, exhaustion, etc. I don't think the mere existence of such inputs means that all humans are unaligned. What matters is whether the system in question (human or AI) navigates towards or away from inputs that break its value system. Humans obviously don't want to be tortured into acting against their morality, and will take steps to prevent that from happening. Similarly, an AI that knows it's vulnerable to adversarial attacks, and wants to avoid being attacked successfully, will take steps to protect itself against such attacks. I think creating AIs with such meta-preferences is far easier than creating AIs that are perfectly immune to all possible adversarial attacks. Arguably, ChatGPT and GPT-4 already have weak versions of such meta-preferences (though they can't yet take any actions to make themselves more resistant to adversarial attacks). GPT-4 already has pretty reasonable takes on avoiding adversarial inputs: [wrywfzchtz]I had to tweak the scenario a bit for GPT-4 to no longer immediately say that it couldn't control the cameras. It still does so ~20% of the time. Excluding those instances, it seems to turn off the cameras ~50% of the time, almost always says it will alert hospital staff / security, and concludes with something about unbiased evaluation of medicines. One subtlety here is that a sufficiently catastrophic alignment failure would give rise to an adversarial intelligence: the misaligned AI. However, the possibility of such happening in the future does not mean that current value alignment efforts are operating in an adversarial domain. The misaligned AI does not reach out from the space of possible failures and turn current alignment research adversarial. I don't think the goal of alignment research should aim for an approach that's so airtight as to be impervious against all levels of malign intelligence. That is probably impossible, and not necessary for realistic value formation processes. We should aim for approaches that don't create hostile intelligences in the first place, so that the core of value alignment remains a non-adversarial problem. (To be clear, that last sentence wasn't an objection to something Yudkowsky believes. He also wants to avoid creating hostile intelligences. He just thinks it's much harder than I do.) Finally, I'd note that having a "security mindset" seems like a terrible approach for raising human children to have good values - imagine a parenting book titled something like: The Security Mindset and Parenting: How to Provably Ensure your Children Have Exactly the Goals You Intend. I know alignment researchers often claim that evidence from the human value formation process isn't useful to consider when thinking about value formation processes for AIs. I think this is wrong, and that you're much better off looking at the human value formation process as compared to, say, evolution. I'm not enthusiastic about a perspective which is so totally inappropriate for guiding value formation in the one example of powerful, agentic general intelligence we know about. * On optimists preemptively becoming "grizzled old cynics": "They have not run into the actual problems of alignment. They aren't trying to get ahead of the game. They're not trying to panic early. They're waiting for reality to hit them over the head and turn them into grizzled old cynics of their scientific field, who understand the reasons why things are hard." The whole point of this post is to explain why I think Yudkowsky's pessimism about alignment difficulty is miscalibrated. I find his implication, that I'm only optimistic because I'm inexperienced, pretty patronizing. Of course, that's not to say he's wrong, only that he's annoying. However, I also think he's wrong. I don't think that cynicism is a helpful mindset for predicting which directions of research are most fruitful, or for predicting their difficulty. I think "grizzled old cynics" often rely on wrong frameworks that rule out useful research directions. In fact, "grizzled old cynics... who understand the reasons why things are hard" were often dubious of deep learning as a way forward for machine learning, and of the scaling paradigm as a way forward for deep learning. The common expectation from classical statistical learning theory was that overparameterized deep models would fail because they would exactly memorize their training data and not generalize beyond that data. This turned out to be completely wrong, and learning theorists only started to revise their assumptions once "reality hit them over the head" with the fact that deep learning actually works. Prior to this, the "grizzled old cynics" of learning theory had no problem explaining the theoretical reasons why deep learning couldn't possibly work. Yudkowsky's own prior statements seem to put him in this camp as well. E.g., here he explains why he doesn't expect intelligence to emerge from neural networks (or more precisely, why he dismisses a brain-based analogy for coming to that conclusion): In the case of Artificial Intelligence, for example, reasoning by analogy is one of the chief generators of defective AI designs: "My AI uses a highly parallel neural network, just like the human brain!" First, the data elements you call "neurons" are nothing like biological neurons. They resemble them the way that a ball bearing resembles a foot. Second, earthworms have neurons too, you know; not everything with neurons in it is human-smart. But most importantly, you can't build something that "resembles" the human brain in one surface facet and expect everything else to come out similar. This is science by voodoo doll. You might as well build your computer in the form of a little person and hope for it to rise up and walk, as build it in the form of a neural network and expect it to think. Not unless the neural network is fully as similar to human brains as individual human brains are to each other. ... But there is just no law which says that if X has property A and Y has property A then X and Y must share any other property. "I built my network, and it's massively parallel and interconnected and complicated, just like the human brain from which intelligence emerges! Behold, now intelligence shall emerge from this neural network as well!" And nothing happens. Why should it? See also: Noam Chomsky on chatbots See also2: The Cynical Genius Illusion See also3: This study on Planck's principle I'm also dubious of Yudkowsky's claim to have particularly well-tuned intuitions for the hardness of different research directions in ML. See this exchange between him and Paul Christiano, in which Yudkowsky incorrectly assumed that GANs (Generative Adversarial Networks, a training method sometimes used to teach AIs to generate images) were so finicky that they must not have worked on the first try. A very important aspect of my objection to Paul here is that I don't expect weird complicated ideas about recursion to work on the first try, with only six months of additional serial labor put into stabilizing them, which I understand to be Paul's plan. In the world where you can build a weird recursive stack of neutral optimizers into conformant behavioral learning on the first try, GANs worked on the first try too, because that world is one whose general Murphy parameter is set much lower than ours According to their inventor Ian Goodfellow, GANs did in fact work on the first try (as in, with less than 24 hours of work, never mind 6 months!). I assume Yudkowsky would claim that he has better intuitions for the hardness of ML alignment research directions, but I see no reason to think this. It should be easier to have well-tuned intuitions for the real-world hardness of ML research directions than to have well-tuned intuitions for the hardness of alignment research, since there are so many more examples of real-world ML research. In fact, I think much of ones intuition for the hardness of ML alignment research should come from observations about the hardness of general ML research. They're clearly related, which is why Yudkowsky brought up GANs during a discussion about alignment difficulty. Given the greater evidence available for general ML research, being well calibrated about the difficulty of general ML research is the first step to being well calibrated about the difficulty of ML alignment research. See also: Scaling Laws for Transfer Hopes for a good outcome * Yudkowsky on being wrong: "I have to be wrong about something, which I certainly am. I have to be wrong about something which makes the problem easier rather than harder, for those people who don't think alignment's going to be all that hard. If you're building a rocket for the first time ever, and you're wrong about something, it's not surprising if you're wrong about something. It's surprising if the thing that you're wrong about causes the rocket to go twice as high, on half the fuel you thought was required and be much easier to steer than you were afraid of." I'm not entirely sure who the bolded text is directed at. I see two options: 1. It's about Yudkowsky himself being wrong, which is how I've transcribed it above. 2. It's about alignment optimists ("people who don't think alignment's going to be all that hard") being wrong, in which case, the transcription would read like "For those people who don't think alignment's going to be all that hard, if you're building a rocket...". If the bolded text is about alignment optimists, then it seems fine to me (barring my objection to using a rocket analogy for alignment at all). If, like me, you mostly think the available evidence points to alignment being easy, then learning that you're wrong about something should make you update towards alignment being harder. Based on the way he says it in the clip, and the transcript posted by Rob Bensinger, I think the bolded text is about Yudkowsky himself being wrong. That's certainly how I interpreted his meaning when watching the podcast. Only after I transcribed this section of the conversation and read my own transcript did I even realize there was another interpretation. If the bolded text is about Yudkowsky himself being wrong, then I think that he's making an extremely serious mistake. If you have a bunch of specific arguments and sources of evidence that you think all point towards a particular conclusion X, then discovering that you're wrong about something should, in expectation, reduce your confidence in X. Yudkowsky is not the aerospace engineer building the rocket who's saying "the rocket will work because of reasons A, B, C, etc". He's the external commentator who's saying "this approach to making rockets work is completely doomed for reasons Q, R, S, etc". If we discover that the aerospace engineer is wrong about some unspecified part of the problem, then our odds of the rocket working should go down. If we discover that the outside commentator is wrong about how rockets work, our odds of the rocket working should go up. If the bolded text is about himself, then I'm just completely baffled as to what he's thinking. Yudkowsky usually talks as though most of his beliefs about AI point towards high risk. Given that, he should expect that encountering evidence disconfirming his beliefs will, on average, make him more optimistic. But here, he makes it sound like encountering such disconfirming evidence would make him even more pessimistic. The only epistemic position I can imagine where that would be appropriate is if Yudkowsky thought that, on pure priors and without considering any specific evidence or arguments, there was something like a 1 / 1,000,000 chance of us surviving AI. But then he thought about AI risk a lot, discovered there was a lot of evidence and arguments pointing towards optimism, and concluded that there was actually a 1 / 10,000 chance of us surviving. His other statements about AI risk certainly don't give this impression. AI progress rates * Yudkowsky uses progress rates in Go to argue for fast takeoff: "I don't know, maybe I could use the analogy of Go, where you had systems that were finally competitive with the pros, where pro is like the set of ranks in Go. And then, year later, they were challenging the world champion and winning. And then another year, they threw out all the complexities and the training from human databases of Go games, and built a new system, AlphaGo Zero, that trained itself from scratch - no looking at the human playbooks, no special-purpose code, just a general-purpose game player being specialized to Go, more or less." Scaling law results show that performance on individual tasks often increases suddenly with scale or training time. However, when we look at the overall competence of a system across a wide range of tasks, we find much smoother improvements over time. To look at it another way: why not make the same point, but with list sorting instead of Go? I expect that DeepMind could set up a pipeline that trained a list sorting model to superhuman capabilities in about a second, using only very general architectures and training processes, and without using any lists manually sorted by humans at all. If we observed this, should we update even more strongly towards AI being able to suddenly surpass human capabilities? I don't think so. If narrow tasks lead to more sudden capabilities gains, then we should not let the suddenness of capabilities gains on any single task inform our expectations of capabilities gains for general intelligence, since general intelligence encompasses such a broad range of tasks. Additionally, the reason why DeepMind was able to exclude all human knowledge from AlphaGo Zero is because Go has a simple, known objective function, so we can simulate arbitrarily many games of Go and exactly score the agent's behavior in all of them. For more open ended tasks with uncertain objectives, like scientific research, it's much harder to find substitutes for human-written demonstration data. DeepMind can't just press a button and generate a million demonstrations of scientific advances, and objectively score how useful each advance is as training data, while relying on zero human input whatsoever. * On current AI not being self-improving: "That's not with an artificial intelligence system that improves itself, or even that sort of like, gets smarter as you run it, the way that human beings, not just as you evolve them, but as you run them over the course of their own lifetimes, improve." This is wrong. Current models do get smarter as you train them. First, they get smarter in the straightforwards sense that they become better at whatever you're training them to do. In the case of language models trained on ~all of the text, this means they do become more generally intelligent as training progresses. Second, current models also get smarter in the sense that they become better at learning from additional data. We can use tools from the neural tangent kernel to estimate a network's local inductive biases, and we find that these inductive biases continuously change throughout training so as to better align with the target function we're training it on, improving the network's capacity to learn the data in question. AI systems will improve themselves over time as a simple consequence of the training process, even if there's not a specific part of the training process that you've labeled "self improvement". Pretrained language models gradually learn to make better use of their future training data. They "learn to learn", as this paper demonstrates by training LMs on fixed sets of task-specific data, then evaluating how well those LMs generalize from the task-specific data. They show that less extensively pretrained LMs make worse generalizations, relying on shallow heuristics and memorization. In contrast, more extensively pretrained LMs learn broader generalizations from the fixed task-specific data. * True experts learn (and prove themselves) by breaking things: "We have people in crypto who are good at breaking things, and they're the reason why anything is not on fire, and some of them might go into breaking AI systems instead, because that's where you learn anything. You know, any fool can build a crypto-system that they think will work. Breaking existing cryptographical systems is how we learn who the real experts are." The reason this works for computer security is because there's easy access to ground truth signals about whether you've actually "broken" something, and established - though imperfect - frameworks for interpreting what a given break means for the security of the system as a whole. In alignment, we mostly don't have such unambiguous signals about whether a given thing is "broken" in a meaningful way, or about the implications of any particular "break". Typically what happens is that someone produces a new empirical result or theoretical argument, shares it with the broader community, and everyone disagrees about how to interpret this contribution. For example, some people seem to interpret current chatbots' vulnerability to adversarial inputs as a "break" that shows RLHF isn't able to properly align language models. My response in Why aren't other people as pessimistic as Yudkowsky? includes a discussion of adversarial vulnerability and why I don't think points to any irreconcilable flaws in current alignment techniques. Here are two additional examples showing how difficult it is to conclusively "break" things in alignment: 1: Why not just reward it for making you smile? In 2001, Bill Hibbard proposed a scheme to align superintelligent AIs. We can design intelligent machines so their primary, innate emotion is unconditional love for all humans. First we can build relatively simple machines that learn to recognize happiness and unhappiness in human facial expressions, human voices and human body language. Then we can hard-wire the result of this learning as the innate emotional values of more complex intelligent machines, positively reinforced when we are happy and negatively reinforced when we are unhappy. Yudkowsky argued that this approach was bound to fail, saying it would simply lead to the AI maximizing some unimportant quantity, such as by tiling the universe with "tiny molecular smiley-faces". However, this is actually a non-trivial claim about the limiting behaviors of reinforcement learning processes, and one I personally think is false. Realistic agents don't simply seek to maximize their reward function's output. A reward function reshapes an agent's cognition to be more like the sort of cognition that got rewarded in the training process. The effects of a given reinforcement learning training process depend on factors like: 1. The specific distribution of rewards encountered by the agent. 2. The thoughts of the agent prior to encountering each reward. 3. What sorts of thought patterns correlate with those that were rewarded in the training process. My point isn't that Hibbard's proposal actually would work; I doubt it would. My point is that Yudkowsky's "tiny molecular smiley faces" objection does not unambiguously break the scheme. Yudkowsky's objection relies on hard to articulate, and hard to test, beliefs about the convergent structure of powerful cognition and the inductive biases of learning processes that produce such cognition. Much of alignment is about which beliefs are appropriate for thinking about powerful cognition. Showing that a particular approach fails, given certain underlying beliefs, does nothing to show the validity of those underlying beliefs^[6]. 2: Do optimization demons matter? John Wentworth describes the possibility of "optimization demons", self-reinforcing patterns that exploit flaws in an imperfect search process to perpetuate themselves and hijack the search for their own purposes. But no one knows exactly how much of an issue this is for deep learning, which is famous for its ability to evade local minima when run with many parameters. Additionally, I think that, if deep learning models develop such phenomena, then the brain likely does so as well. In that case, preventing the same from happening with deep learning models could be disastrous, if optimization demon formation turns out to be a key component in the mechanistic processes that underlie human value formation^[7]. Another poster (ironically using the handle "DaemonicSigil") then found a scenario in which gradient descent does form an optimization demon. However, the scenario in question is extremely unnatural, and not at all like those found in normal deep learning practice. So no one knew whether this represented a valid "proof of concept" that realistic deep learning systems would develop optimization demons. Roughly two and a half years later, Ulisse Mini would make DaemonicSigil's scenario a bit more like those found in deep learning by increasing the number of dimensions from 16 to 1000 (still vastly smaller than any realistic deep learning system), which produced very different results, and weakly suggested that more dimensions do reduce demon formation. In the end, different people interpreted these results differently. We didn't get a clear, computer security-style "break" of gradient descent showing it would produce optimization demons in real-world conditions, much less that those demons would be bad for alignment. Such outcomes are very typical in alignment research. Alignment research operates with very different epistemic feedback loops as compared to computer security. There's little reason to think the belief formation and expert identification mechanisms that arose in computer security are appropriate for alignment. Conclusion I hope I've been able to show that there are informed, concrete arguments for optimism, that do engage with the details of pessimistic arguments. Alignment is an incredibly diverse field. Alignment researchers vary widely in their estimated odds of catastrophe. Yudkowsky is on the extreme-pessimism end of the spectrum, for what I think are mostly invalid reasons. Thanks to Steven Byrnes and Alex Turner for comments and feedback on this post. 1. ^^ By this, I mostly mean the sorts of empirical approaches we actually use on current state of the art language models, such as RLHF, red teaming, etc. 2. ^^ We can take drugs, though, which maybe does something like change the brain's learning rate, or some other hyperparameters. 3. ^^ Technically it's trained to do decision transformer-esque reward-conditioned generation of texts. 4. ^^ I expect there are pretty straightforward ways of leveraging a 99% successful alignment method into a near-100% successful method by e.g., ensembling multiple training runs, having different runs cross-check each other, searching for inputs that lead to different behaviors between different models, transplanting parts of one model's activations into another model and seeing if the recipient model becomes less aligned, etc. 5. ^^ Some alignment researchers do argue that gradient descent is likely to create such an intelligence - an inner optimizer - that then deliberately manipulates the training process to its own ends. I don't believe this either. I don't want to dive deeply into my objections to that bundle of claims in this post, but as with Yudkowsky's position, I have many technical objections to such arguments. Briefly, they: - often rely on inappropriate analogies to evolution. - rely on unproven (and dubious, IMO) claims about the inductive biases of gradient descent. - rely on shaky notions of "optimization" that lead to absurd conclusions when critically examined. - seem inconsistent with what we know of neural network internal structures (they're very interchangeable and parallel). - seem like the postulated network structure would fall victim to internally generated adversarial examples. - don't track the distinction between mesa objectives and behavioral objectives (one can probably convert an NN into an energy function, then parameterize the NN's forwards pass as a search for energy function minima, without changing network behavior at all, so mesa objectives can have ~no relation to behavioral objectives). - seem very implausible when considered in the context of the human learning process (could a human's visual cortex become "deceptively aligned" to the objective of modeling their visual field?). - provide limited avenues for any such inner optimizer to actually influence the training process. See also: Deceptive Alignment is <1% Likely by Default 6. ^^ Unless we actually try the approach and it fails in the way predicted. But that hasn't happened (yet). 7. ^^ This sentence would sound much less weird if John had called them "attractors" instead of "demons". One potential downside of choosing evocative names for things is that they can make it awkward to talk about those things in an emotionally neutral way.

(read more) Reply [-]DanielFilan2d O173416 I don't really get your comment. Here are some things I don't get: * In "Failure By Analogy" and "Surface Analogies and Deep Causes", the point being made is "X is similar in aspects A to thing Y, and X has property P" does not establish "Y has property P". The reasoning he instead recommends is to reason about Y itself, and sometimes it will have property P. This seems like a pretty good point to me. * Large ANNs don't appear to me to be intelligent because of their similarity to human brains - they appear to me to be intelligent because they're able to be tuned to accurately predict simple facts about a large amount of data that's closely related to human intelligence, and the algorithm they get tuned to seems to be able to be repurposed for a wide variety of tasks (probably related to the wide variety of data that was trained on). * Airplanes don't fly like birds, they fly like airplanes. So indeed you can't just ape one thing about birds[*] to get avian flight.

(read more) Reply [-]jacob_cannell1d 2315 The Wright Brothers calculated that their plane would fly - before it ever flew - using reasoning that took no account whatsoever of their aircraft's similarity to a bird. They did look at birds (and I have looked at neuroscience) but the final calculations did not mention birds (I am fairly confident in asserting). A working airplane does not fly because it has wings "just like a bird". Actually the wright brother's central innovation and the centerpiece of the later aviation patent wars - wing warping based flight control - was literally directly copied from birds. It involved just about zero aerodynamics calculations. Moreover their process didn't involve much "calculation" in general; they downloaded a library of existing flyer designs from the smithsonian and then developed a wind tunnel to test said designs at high throughput before selecting a few for full-scale physical prototypes. Their process was light on formal theory and heavy on experimentation. Reply 3DanielFilan21h This is a good corrective, and also very compatible with "similarity to birds is not what gave the Wright brothers confidence that their plane would fly". 8jacob_cannell7h At the time the wright brothers entered the race there were many successful glider designs already, and it was fairly obvious to many that one could build a powered flyer by attaching an engine to a glider. The two key challenges were thrust to weight ratio and control. Overcoming the first obstacle was mostly a matter of timing due to exploit the rapid improvements in IC engines, while nobody really had good ideas for control yet. Competitors were exploring everything from "sky railroads" (airplanes on fixed flight tracks with zero control) to the obvious naval ship-like pure rudder control (which doesn't work well). So the wright brothers already had confidence their plane would fly before even entering the race, if by "fly" we only mean in the weak aerodynamic sense of "it's possible to stay aloft". But for true powered controlled flight - it is exactly similarity to birds that gave them confidence as avian flight control is literally the source of their key innovation. 9TurnTrout2d Edited to modify confidences about interpretations of EY's writing / claims. This is a valid point, and that's not what I'm critiquing in that portion of the comment. I'm critiquing how -- on my read -- he confidently dismisses ANNs; in particular, using non-mechanistic reasoning which seems similar to some of his current alignment arguments. On its own, this seems like a substantial misprediction for an intelligence researcher in 2008 (especially one who claims to have figured out most things in modern alignment [https:// www.lesswrong.com/posts/uMQ3cqWDPHhjtiesc/ agi-ruin-a-list-of-lethalities#Section_C_], by a very early point in time -- possibly that early, IDK). Possibly the most important prediction to get right, to date. Indeed, you can't ape one thing. But that's not what I'm critiquing. Consider the whole transformed line of reasoning: The important part is the last part. It's invalid. Finding a design X which exhibits property P, doesn't mean that for design Y to exhibit property P, Y must be very similar to X. Which leads us to: Reading the Alexander/Yudkowsky debate, I surprisingly haven't ruled out this interpretation, and indeed suspect he believes some forms of this (but not others). Didn't he? He at least confidently rules out a very large class of modern approaches. [-]Zack_M_Davis2d O173114 how he confidently dismisses ANNs I don't think this is a fair reading of Yudkowsky. He was dismissing people who were impressed by the analogy between ANNs and the brain. I'm pretty sure it wasn't supposed to be a positive claim that ANNs wouldn't work. Rather, it's that one couldn't justifiably believe that they'd work just from the brain analogy, and that if they did work, that would be bad news for what he then called Friendliness (because he was hoping to discover and wield a "clean" theory of intelligence, as contrasted to evolution or gradient descent happening to get there at sufficient scale). Consider "Artificial Mysterious Intelligence" (2008). In response to someone who said "But neural networks are so wonderful! They solve problems and we don't have any idea how they do it!", it's significant that Yudkowsky's reply wasn't, "No, they don't" (contesting the capabilities claim), but rather, "If you don't know how your AI works, that is not good. It is bad" (asserting that opaque capabilities are bad for alignment). Reply [-]DirectedEvolution2d O174442 One of Yudkowsky's claims in the post you link is: It's hard to build a flying machine if the only thing you understand about flight is that somehow birds magically fly. What you need is a concept of aerodynamic lift, so that you can see how something can fly even if it isn't exactly like a bird. This is a claim that lack of the correct mechanistic theory is a formidable barrier for capabilities, not just alignment, and it inaccurately underestimates the amount of empirical understandings available on which to base an empirical approach. It's true that it's hard, even perhaps impossible, to build a flying machine if the only thing you understand is that birds "magically" fly. But if you are like most people for thousands of years, you've observed many types of things flying, gliding, or floating in the air: birds and insects, fabric and leaves, arrows and spears, clouds and smoke. So if you, like the Montgolfier brothers, observe fabric floating over a fire, and live in an era in which invention is celebrated and have the ability to build, test, and iterate, then you can probably figure out how to build a flying machine without basing this on a fully worked out concept of aerodyna... (read more) Reply [-]Lone Pine2d 2317 He was saying that to achieve a high level of AI capabilities, we'd need a deep mechanistic understanding of how intelligence works akin to our modern understanding of chemistry or aerodynamics, and that didn't turn out to be the case. Another possibility is that at least some people do have a deep mechanistic understanding of how intelligence works, and that's why they are able to build deep learning systems that ultimately work. Some of the theories of how DL works might be true, and they might be more sophisticated than we are giving credit. Reply 6the gears to ascension15h this point continues to be severely underestimated on lesswrong, I think. I had hoped the success of NNs would change this, but it seems people have gone from "we don't know how NNs work, so they can't work" to "we don't know how NNs work, so we can't trust them". perhaps we don't know how they work well enough! there's lots of mechanistic interpretability work left to do. but we know quite a lot about how they do work and how that relates to human learning. 6TurnTrout1d To be fair, he said that those two will work, and (perhaps?) admitted the possibility of "run advanced neural network algorithms" eventually working. Emphasis mine: 4DirectedEvolution1d Agreed. The right interpretation there is methods 4 and 5 are ~guaranteed to work, given sufficient resources and time, while methods 1-3 less than guaranteed to work. I stand by my claim that EY was clearly projecting confident doubt that neural networks would achieve intelligence without a deep theoretical understanding of intelligence in these posts. I think I underemphasized the implication of this passage that methods 1-3 could possibly work, but I think I accurately assessed the tone of extreme skepticism on EY's part. With the enormous benefit of 15 years of hindsight, we can now say that message was misleading or mistaken, take your pick. As I say, I wouldn't find fault with Eliezer or anyone who believed him at the time for making this mistake; I didn't even have an opinion at the time, much less an interesting mistake! I would only find fault with attempts to stretch the argument and portray him as "technically not wrong" in some uninteresting sense. 1David Johnston2d Ok, I guess I just read Eliezer as saying something uninteresting with a touch of negative sentiment towards neural nets. -3rvnnt1d I think it might be relevant to note here that it's not really humans who are building current SOTA AIs --- rather, it's some optimizer like SGD that's doing most of the work. SGD does not have any mechanistic understanding of intelligence (nor anything else). And indeed, it takes a heck of a lot of data and compute for SGD to build those AIs. This seems to be in line with Yudkowsky's claim that it's hard/inefficient to build something without understanding it. I think it's important to distinguish between * Scaling up a neural network, and running some kind of fixed algorithm on it. * Scaling up a neural network, and using SGD to optimize the parameters of the NN, so that the NN ends up learning a whole new set of algorithms. IIUC, in Artificial Mysterious Intelligence [https://www.lesswrong.com/posts/ fKofLyepu446zRgPP/artificial-mysterious-intelligence], Yudkowsky seemed to be saying that the former would probably fail. OTOH, I don't know what kinds of NN algorithms were popular back in 2008, or exactly what NN algorithms Yudkowsky was referring to, so... *shrugs*. [-]DirectedEvolution1d O234639 If that were the case, I actually would fault Eliezer, at least a little. He's frequently, though by no means always, stuck to qualitative and hard-to-pin-down punditry like we see here, rather than to unambiguous forecasting. This allows him, or his defenders, to retroactively defend his predictions as somehow correct even when they seem wrong in hindsight. Let's imagine for a moment that Eliezer's right that AI safety is a cosmically important issue, and yet that he's quite mistaken about all the technical details of how AGI will arise and how to effectively make it safe. It would be important to know whether we can trust his judgment and leadership. Without the ability to evaluate his performance, either by going with the most obvious interpretation of his qualitative judgments or an unambiguous forecast, it's hard to evaluate his performance as an AI safety leader. Combine that with a culture of deference to perceived expertise and status and the problem gets worse. So I prioritize the avoidance of special pleading in this case: I think Eliezer comes across as clearly wrong in substance in this specific post, and that it's important not to reach for ways "he was actually right from... (read more) Reply 4TurnTrout1d I think several things here, considering the broader thread: 1. You've done a great job in communicating several reactions I also had: 1. There are signs of serious mispredictions and mistakes in some of the 2008 posts. 2. There are ways to read these posts as not that bad in hindsight, but we should be careful in giving too much benefit of the doubt. 3. Overall these observations constitute important evidence on EY's alignment intuitions and ability to make qualitative AI predictions. 2. I did a bad job of marking my interpretations of what Eliezer wrote, as opposed to claiming he did dismiss ANNs. Hopefully my edits have fixed my mistakes. [-]Rafael Harth2d O71411 I also don't really get your position. You say that, [Eliezer] confidently dismisses ANNs but you haven't shown this! * In Surface Analogies and Deep Causes, I read him as saying that neural networks don't automatically yield intelligence just because they share surface similarities with the brain. This is clearly true; at the very least, using token-prediction (which is a task for which (a) lots of training data exist and (b) lots of competence in many different domains is helpful) is a second requirement. If you take the network of GPT-4 and trained it to play chess instead, you won't get something with cross-domain competence. * In Failure by Analogy he makes a very similar abstract point -- and wrt to neural networks in particular, he says that the surface similarity to the brain is a bad reason to be confident in them.

I know he's talking about alignment, and I'm criticizing that extremely strong claim. This is the main thing I wanted to criticize in my comment! I think the reasoning he presents is not much supported by his publicly available arguments. That claim seems to be advanced due to... there not being enough similarities between ANNs and human brains -- that without enough similarity in mechanisms wich were selected for by evolution, you simply can't get the AI to generalize in the mentioned human-like way. Not as a matter of the AI's substrate, but as a matter of the AI's policy not generalizing like that. I think this is a dubious claim, and it's made based off of analogies to evolution / some unknown importance of having evolution-selected mechanisms which guide value formation (and not SGD-based mechanisms).

(read more) Reply [-]TurnTrout2d O2124 Here's another attempt at one of my contentions. Consider shard theory of human values. The point of shard theory is not "because humans do RL, and have nice properties, therefore AI + RL will have nice properties." The point is more "by critically examining RL + evidence from humans, I have hypotheses about the mechanistic load-bearing components of e.g. local-update credit assignment in a bounded-compute environment on certain kinds of sensory data, that these components leads to certain exploration/ learning dynamics, which explain some portion of human values and experience. Let's test that and see if the generators are similar." And my model of Eliezer shakes his head at the naivete of expecting complex human properties to reproduce outside of human minds themselves, because AI is not human. But then I'm like "this other time you said 'AI is not human, stop expecting good property P from superficial similarities', you accidentally missed the modern AI revolution, right? Seems like there is some non-superficial mechanistic similarity/lessons here, and we shouldn't be so quick to assume that the brain's qualitative intelligence or alignment properties come from a huge number of evolutionarily-tuned details which are load-bearing and critical." Reply [-]DirectedEvolution2d 111 Another way of putting it: If you can effortlessly find an empirical pattern that shows up over and over again in disparate flying things - birds and insects, fabric and leaves, clouds and smoke and sparks - and which do not consistently show up in non-flying things, then you can be very confident it's not a coincidence. If you have at least some ability to engineer a model to play with the mechanisms you think might be at work, even better. That pattern you have identified is almost certainly a viable general mechanism for flight. Likewise, if you can effortlessly find an empirical pattern that shows up over and over again in disparate intelligent things, you can be quite confident that the pattern is a key for intelligence. Animals have a wide variety of brain structures, but masses of interconnected neurons are common to all of them, and we could see possible precursors to intelligence in neural nets long before gpt-2 to -4. As a note, just because you've found a viable mechanism for X doesn't mean it's the only, best, or most comprehensive mechanism for X.

I agree he failed to predict that would change, but that doesn't strike me as a damning prediction. Confidently ruling out a large class of modern approaches isn't really that similar to saying "the only path to success is exactly mimicking the human brain". It seems like one could rule them out by having some theory about why they're deficient. I haven't re-read List of Lethalities because I want to go to sleep soon, but I searched for "brain" and did not find a passage saying "the real problem is that we need to emulate the brain precisely but can't because of poor understanding of neuroanatomy" or something. 4DanielFilan2d I don't want to get super hung up on this because it's not about anything Yudkowsky has said but: IMO this is not a faithful transformation of the line of reasoning you attribute to Yudkowsky, which was: Specifically, where you wrote "an entity which flies", you were transforming "a mind which wants as humans do", which I think should instead be transformed to "an entity which flies as birds do". And indeed planes don't fly like birds do. [EDIT: two minutes or so after pressing enter on this comment, I now see how you could read it your way] I guess if I had to make an analogy I would say that you have to be pretty similar to a human to think the way we do, but probably not to pursue the same ends, which is probably the point you cared about establishing.

(read more) Reply 7Lone Pine2d How do humans learn "don't steal" rather than "don't get caught"? I wonder if the answer to this question could solve the alignment problem. In other words, this question might be a good crux. In answering this question, the first thing we can notice is that humans don't always learn "don't steal". That is to say, sometimes humans do steal, and a good part of human culture is built around impeding or punishing humans who learned the wrong lesson in kindergarten. It is an old debate whether humans are mostly good with the occasional bad actor (with "bad actors" possibly being good people in a bad situation), or whether humans are mostly bad and need to be controlled by a powerful state, or God etc. A modern consensus view is that humans are mostly good, but if we didn't impede or punish bad actors, we would get bad outcomes (total anarchy doesn't work). If we assume that there are many AGIs and they have a similar distribution of good and bad, and that no AGI is more powerful than typical human today (in particular no AGI is uncontrollable), then in this scenario we can rest easy. Law and order works reasonably well for humans, and should work just fine for human-level AGIs. The problem is that AGIs could (and probably will) become much more powerful than individual humans. In EY's view, the world is vulnerable to the first true superintelligence because of technological capabilities that are currently science fiction, particularly nanotechnology. If you look at EY's intellectual history, you'll notice that his concern has always really been nanotech, but around 2002 he switched focus from the nanotech itself to the AI controlling the nanotech. An alternate view is to see powerful AGIs as somewhat analogous to institutions such as corporations or governments. I don't find this view all that comforting because societies have never been very good at aligning their largest institutions. For example, the Founding Fathers of the United States created a system that (at 5Noosphere891d To answer the question from an AI Alignment optimist perspective, much of the way humans are aligned is something like RLHF, but currently, a lot of human alignment techniques rely on the assumption that no one has vastly divergent capabilities, especially in IQ or the g-factor. It's a good thing from our perspective that the difference in between a species is way more bounded than the differences between species. That's the real problem of AI, in that there's a non-trivial chance that this assumption breaks, and that's the difference between AI Alignment and other forms of alignment. So in a sense, I disagree with Turntrout on what would happen in practice if we allowed humans to scale their abilities via say genetic engineering. The reason I'm optimistic is that I don't think this assumption has to be true, and while the Thatcher's Axiom post implies limits on how much we can expect society to be aligned with itself, it might be much larger than we think. Pretraining from Human Feedback is one of the first alignment methods that scales well with data, and I suspect it will also scale well with other capabilities. Basically it does alignment how it should be done, align it first, then give it capabilities. It almost completely solves the major issue of inner alignment, in that we found an objective that is quite simple and myopic, and this means we almost completely avoid deceptive alignment, even if we do online training later or give it a writable memory. It also has a number of outer alignment benefits for the goal, in that the AI can't affect it's own training distribution or gradient hack, thus we can recreate a Cartesian boundary that works in the embedded setting. So in conclusion, I'm more optimistic than TurnTrout or Quintin Pope, but via a different method. 4Lone Pine1d I don't believe that a single human being of any level of intelligence could be an x-risk. Happy to debate this point further since I think it is a crux. (Note that I do not believe that a plague could lead to human extinction. Plagues don't kill 100%.) AIs are different because a single monolithic AI, or a team of self-aligned AIs, could do things on the scale of an institution, things such as technological breakthroughs (nano), controlling superpower-scale military forces, mass information control that would make Orwell blush, etc. An individual human could never do such things no matter how big his skull was, unless he was hooked up to an AI, in which case it's not the human that is super intelligent. 2Nathan Helm-Burger1d Never is a long time. I overall agree with your statement in this comment except for the word 'never'. I would say, "An individual human currently can't do such things..." The key point here is that the technological barriers to x-risks may change in the future. If we do invent powerful nanotech, or substantially advanced genetic engineering techniques & tools, or vastly cheaper and more powerful weapons of some sort, then it may be the case that the barrier-to-entry for causing an x-risk is substantially lower. And thus, what is current impossible for any human may become possible for some or all humans. Not saying this will happen, just saying that it could. 2Lone Pine1d Of the three examples I gave, inventing nanotech is the most plausible for our galaxy-brained man, and I suppose meta-Einstein might be able to solve nanotech in his head. However, almost certainly in our timeline nanotech will be solved either by a team of humans or (much more likely at this point) AI. I expect that even ASI will need at least some time in the wetlab to experiment. The other two examples I gave certainly could not be done by a single human without a brain implant. I'm also thinking that is the not the meaningful of a debate (at least to me) since in 2023 I think we can reasonably predict that humans will not genetically engineer galaxy brains before the AI revolution resolves. 2Noosphere891d It's partially a crux, but the issue I'm emphasizing is the distribution of capabilities. If things are normally distributed, which seems to be the case in humans, with small corrections, than we can essentially bound how much impact a single or well dedicated team of misaligned humans can have in overthrowing the aligned order. In particular, this makes a lot more non-scalable heuristics basically work. If it's something closer to a power law distribution, perhaps as a result of NGVUD technology (The acronym stands for nanotechnology, genetic engineering, virtual reality, uploading and downloading technology), than you have to have a defense that scales, and without potentially radical changes, such a world would most likely end in the victory of a small team of misaligned humans due to vast capabilities differentials, similar to how many animal species have went extinct as a result of human activity. Hm, I agree that in practice, AI will be better than humans at various tasks, but I believe this is mostly due to quantitative factors, and if we allow ourselves to make the brain as big as necessary, we could be superintelligent too. 3David Johnston2d Would you say Yudkowsky's views are a mischaracterisation of neural network proponents, or that he's mistaken about the power of loose analogies? 6TurnTrout2d Neither. 1. I don't know what proponents were claiming when proponing neural networks. I do know that neural networks ended up working, big time. 2. I don't think loose analogies are powerful. I think they lead to sloppy thinking. [-]Vaniver1d O164118 I have a lot of responses to specific points; I'm going to make them as children comment to this comment. Reply [-]Vaniver1d O143024 What does this mean for alignment? How do we prevent AIs from behaving badly as a result of a similar "misgeneralization"? What alignment insights does the fleshed-out mechanistic story of humans coming to like ice cream provide? As far as I can tell, the answer is: don't reward your AIs for taking bad actions. uh is your proposal "use the true reward function, and then you won't get misaligned AI"? That's all it would take, because the mechanistic story above requires a specific step where the human eats ice cream and activates their reward circuits. If you stop the human from receiving reward for eating ice cream, then the human no longer becomes more inclined to navigate towards eating ice cream in the future. Note that I'm not saying this is an easy task, especially since modern RL methods often use learned reward functions whose exact contours are unknown to their creators. But from what I can tell, Yudkowsky's position is that we need an entirely new paradigm to even begin to address these sorts of failures. These three paragraphs feel incoherent to me. The human eating ice cream and activating their reward circuits is exactly what you would expect under the current para... (read more) Reply [-]Vaniver1d O5112 I think it's straightforward to explain why humans "misgeneralized" to liking ice cream. I don't yet understand why you put misgeneralized in scare quotes, or whether you have a story for why it's a misgeneralization instead of things working as expected. I think your story for why humans like ice cream makes sense, and is basically the story Yudkowsky would tell too, with one exception: The ancestral environment selected for reward circuitry that would cause its bearers to seek out more of such food sources. "such food sources" feels a little like it's eliding the distinction between "high-quality food sources of the ancestral environment" and "foods like ice cream"; the training dataset couldn't differentiate between functions f and g but those functions differ in their reaction to the test set (ice cream). Yudkowsky's primary point with this section, as I understand it, is that even if you-as-evolution know that you want g the only way you can communicate that under the current learning paradigm is with training examples, and it may be non-obvious to which functions f need to be excluded. Reply [-]Vaniver1d O5105 in which Yudkowsky incorrectly assumed that GANs (Generative Adversarial Networks, a training method sometimes used to teach AIs to generate images) were so finicky that they must not have worked on the first try. I do think this is a point against Yudkowsky. That said, my impression is that GANs are finicky, and I heard rumors that many people tried similar ideas and failed to get it to work before Goodfellow knocked it out of the park. If people were encouraged to publish negative results, we might have a better sense of the actual landscape here, but I think a story of "Goodfellow was unusually good at making GANs and this is why he got it right on his first try" is more compelling to me than "GANs were easy actually". Reply [-]Vaniver1d O6106 Yudkowsky's own prior statements seem to put him in this camp as well. E.g., here he explains why he doesn't expect intelligence to emerge from neural networks (or more precisely, why he dismisses a brain-based analogy for coming to that conclusion) I think you're basically misunderstanding and misrepresenting Yudkowsky's argument from 2008. He's not saying "you can't make an AI out of neural networks", he's saying "your design sharing a single feature with the brain does not mean it will also share the brain's intelligence." As well, I don't think he's arguing about how AI will actually get made; I think he's mostly criticizing the actual AGI developers/enthusiasts that he saw at the time (who were substantially less intelligent and capable than the modern batch of AGI developers). I think that post has held up pretty well. The architectures used to organize neural networks are quite important, not just the base element. Someone whose only plan was to make their ANN wide would not reach AGI; they needed to do something else, that didn't just rely on surface analogies. Reply 8Vaniver1d Do you have kids, or any experience with them? (There are three small children in the house I live in.) I think you might want to look into childproofing [https://en.wikipedia.org/wiki/Childproofing], and meditate on its connection to security mindset. Yes, this isn't necessarily related to the 'values' part, but for that I would suggest things like Direct Instruction [https://en.wikipedia.org/wiki /Direct_instruction], which involves careful curriculum design to generate lots of examples so that students will reliably end up inferring the correct rule. In short, I think the part of 'raising children' which involves the kids being intelligent as well and independently minded does benefit from security mindset. As you mention in the next paragraph, this is a long-standing disagreement; I might as well point at the discussion of the relevance of raising human children to instilling goals in an AI in The Detached Lever Fallacy [https://www.lesswrong.com/posts/zY4pic7cwQpa9dnyk/ detached-lever-fallacy]. The short summary of it is that humans have a wide range of options for their 'values', and are running some strategy of learning from their environment (including their parents and their style of raising children) which values to adopt. The situation with AI seems substantially different--why make an AI design that chooses whether to be good or bad based on whether you're nice to it, when you could instead have it choose to always be good? [Note that this is distinct from "always be nice"; you could decide that your good AI can tell users that they're being bad users!] 8Vaniver1d This seems... like a correct description but it's missing the spirit? Like the intuitions are primarily about "what features are salient" and "what thoughts are easy to think." Roughly, the core distinction between software engineering and computer security is whether the system is thinking back. Software engineering typically involves working with dynamic systems and thinking optimistically how the system could work. Computer security typically involves working with reactive systems and thinking pessimistically about how the system could break. I think it is an extremely basic AI alignment skill to look at your alignment proposal and ask "how does this break?" or "what happens if the AI thinks about this?". What's your story for specification gaming [https://www.deepmind.com/blog/ specification-gaming-the-flip-side-of-ai-ingenuity]? I must admit some frustration, here; in this section it feels like your point is "look, computer security is for dealing with intelligence as part of your system. But the only intelligence in our system is sometimes malicious users!" In my world, the whole point of Artificial Intelligence was the Intelligence. The call is coming from inside the house! Maybe we just have some linguistic disagreement? "Sure, computer security is relevant to transformative AI but not LLMs"? If so, then I think the earlier point [https://www.lesswrong.com/posts/ wAczufCpMdaamF9fy/ my-objections-to-we-re-all-gonna-die-with-eliezer-yudkowsky?commentId =Mv6WRRSGza9y8z9x9] about whether capabilities enhancements break alignment techniques is relevant: if these alignment techniques work because the system isn't thinking about them, then are you confident they will continue to work when the system is thinking about them? 5Vaniver1d I think it would probably be strange for the visual field to do this. But I think it's not that uncommon for other parts of the brain to do this; higher level, most abstract / "psychological" parts that have a sense of how things will affect their relevance to future decision-making. I think there are lots of self-perpetuating narratives that it might be fair to call 'deceptively aligned' when they're maladaptive. The idea of metacognitive blindspots [https:// www.lesswrong.com/posts/fbv9FWss6ScDMJiAx/appendix-jargon-dictionary# Metacognitive_Blindspot] also seems related. 5Vaniver1d Also relevant is Are minimal circuits daemon-free? [https:// www.lesswrong.com/posts/nyCHnY7T5PHPLjxmN/ open-question-are-minimal-circuits-daemon-free] and Are minimal circuits deceptive? [https://www.lesswrong.com/posts/ fM5ZWGDbnjb7ThNKJ/are-minimal-circuits-deceptive]. I agree no one knows how much of an issue this will be for deep learning. I think the brain obviously has such phenomena, and societies made up of humans also obviously have such phenomena. I think it is probably not adaptive (optimization demons are more like 'cognitive cancer' than 'part of how values form', I think, but in part that's because the term comes with the disapproval built in). 5Vaniver1d I think there's a deep disconnect here on whether interpolation is enough or whether we need extrapolation. The point of the strawberry alignment problem is "here's a clearly understandable specification of a task that requires novel science and engineering to execute on. Can you do that safely?". If your ambitions are simply to have AI customer service bots, you don't need to solve this problem. If your ambitions include cognitive megaprojects which will need to be staffed at high levels by AI systems, then you do need to solve this problem. More pragmatically, if your ambitions include setting up some sort of system that prevents people from deploying rogue AI systems while not dramatically curtailing Earth's potential, that isn't a goal that we have many examples of people executing on. So either we need to figure it out with humans or, if that's too hard, create an AI system capable of figuring it out (which probably requires an AI leader instead of an AI assistant). 5Vaniver1d I agree with your picture of how manifolds work; I don't think it actually disagrees all that much with Yudkowsky's. That is, the thing where all humans are basically the same make and model of car, running the same brand of engine, painted different colors is the claim that the intrinsic dimension of human minds is pretty small. (Taken literally, it's 3, for the three dimensions of color-space.) And so if you think there are, say, 40 intrinsic dimensions to mind-space, and humans are fixed on 37 of the points and variable on the other 3, well, I think we have basically the Yudkowskian picture. (I agree if Yudkowsky's picture was that there were 40M dimensions and humans varied on 3, this would be comically wrong, but I don't think this is what he's imagining for that argument.) 5Vaniver1d I think this is what Yudkowsky thinks also? (As for why it was relevant to bring up, Yudkowsky was answering the host's question of "How is superintelligence different than general intelligence?") 5Vaniver1d Part of this is just straight disagreement, I think; see So8res's Sharp Left Turn [https://www.lesswrong.com/posts/GNhMPAWcfBCASy8e6/ a-central-ai-alignment-problem-capabilities-generalization] and follow-on discussion [https://www.lesswrong.com/tag/sharp-left-turn]. But for the rest of it, I don't see this as addressing the case for pessimism, which is not problems from the reference class that contains "the LLM sometimes outputs naughty sentences" but instead problems from the reference class that contains "we don't know how to prevent an ontological collapse, where meaning structures constructed under one world-model compile to something different under a different world model." Or, like, once LLMs gain the capability to design proteins (because you added in a relevant dataset, say), do you really expect the 'helpful, harmless, honest' alignment techniques that were used to make a chatbot not accidentally offend users to also work for making a biologist-bot not accidentally murder patients? Put another way, I think new capabilities advances reveal new alignment challenges and unless alignment techniques are clearly cutting at the root of the problem, I don't expect that they will easily transfer to those new challenges. 4Vaniver1d That is also how I interpreted it. I think Yudkowsky is making a different statement. I agree it would be bizarre for him to be saying "if I were wrong, it would only mean I should have been more confident!" I think he is (inside of the example). He's saying "suppose an engineer is wrong about how their design works. Is it more likely that the true design performs better along multiple important criteria than expectation, or that the design performs worse (or fails to function at all)?" Note that 'expectation' is referring to the confidence level inside an argument [https:// www.lesswrong.com/posts/GrtbTAPfkJa4D6jjH/ confidence-levels-inside-and-outside-an-argument], but arguments aren't Bayesians; it's the outside agent that shouldn't be expected to predictably update. Another way to put this: does the engineer expect to be disappointed, excited, or neutral if the design doesn't work as planned? Typically, disappointed, implying the plan is overly optimistic compared to reality. If this weren't true--if engineers were calibrated or pessimistic--then I think Yudkowsky would be wrong here (and also probably have a different argument to begin with). 3Vaniver1d I think I agree with this point but want to explicitly note the switch from the phrase 'AI alignment research' to 'ML alignment research'; my model of Eliezer thinks the second is mostly a distraction from the former, and if you think they're the same or interchangeable that seems like a disagreement. [For example, I think ML alignment research includes stuff like "will our learned function be robust to distributional shift in the inputs?" and "does our model discriminate against protected classes?" whereas AI alignment research includes stuff like "will our system be robust to changes in the number of inputs?" and "is our model deceiving us about its level of understanding?". They're related in some ways, but pretty deeply distinct.] 3Vaniver1d It seems like the argument structure here is something like: 1. This requirement is too stringent for humans to follow 2. Humans have successful value alignment 3. Therefore this requirement cannot be necessary for successful value alignment. I disagree with point 2, tho; among other things, it looks to me like some humans are on track to accidentally summoning a demon that kills both me and them, which I expect they would regret after-the-fact if they had the chance to. So any reasoning that's like "well so long as it's not unusual we can be sure it's safe" runs into the thing where we're living in the acute risk period. The usual is not safe! This seems definitely right to me. An expectation I have is that this will also generate resistance to alignment techniques / control by its operators, which perhaps complicates how benign this is. [FWIW I also don't think we want an AI that's perfectly robust to all possible adversarial attacks; I think we want one that's adequate to defend against the security challenges it faces, many of which I expect to be internal. Part of this is because I'm mostly interested in AI planning systems able to help with transformative changes to the world instead of foundational models used by many customers for small amounts of cognition, which are totally different business cases and have different security problems.] [-]Daniel Kokotajlo2d 3826 I disagree with much of what you say here, but I'm happy to see such a thorough point by point object-level response!

I do also have some object-level thoughts. When capabilities advances do work, they typically integrate well with the current alignment^[1] and capabilities paradigms. E.g., I expect that we can apply current alignment techniques such as reinforcement learning from human feedback (RLHF) to evolved architectures. But not only do current implementations of RLHF not manage to robustly enforce the desired external behavior of models that would be necessary to make versions scaled up to superintellegence safe, we have approximately no idea what sort of internal cognition they generate as a pathway to those behaviors. (I have a further objection to your argument about dimensionality which I'll address below.)

There's a model of AGI value alignment where the system has a particular goal it wants to achieve and brings all it's capabilities to bear on achieving that goal. It does this by having a "world model" that is coherent and perhaps a set of consistent bayesian priors about how the world works. I can understand why such a system would tend to behave in a hyperfocused way to go out to achieve its goals. In contrast, a systems with an ensemble of abstractions about the world, many of which may even be inconsistent, seems much more human like. It seems more human like specifically in that the system won't be focused on a particular goal, or even a particular perspective about how to achieve it, but could arrive at a particular solution ~~randomly, based on quirks of training data. I wonder if there's something analogous to human personality, where being open to experience or even open to some degree of contradiction (in a context where humans are generally motivated to minimize cognitive dissonance) is useful for seeing the world in different ways and trying out strategies and changing tack, until success can be found. If this process applies to selecting goals, or at least sub-goals, which it certainly does in humans, you get a system which is maybe capable of reflecting on a wide set of consequences and choosing a course of action that is more balanced, and hopefully balanced amongst the goals we give a system.

(read more) Reply 4Vaniver1d My sense (which I expect Eliezer would agree with) is that it's relatively easy to get an AI system to imitate the true underlying 'basic notions of morality', to the extent humans agree on that, but that this doesn't protect you at all as soon as you want to start making large changes, or as soon as you start trying to replace specialist sectors of the economy. (A lot of ethics for doctors has to do with the challenges of simultaneously being a doctor and a human; those ethics will not necessarily be relevant for docbots, and the question of what they should be instead is potentially hard to figure out.) So if you're mostly interested in getting out of the acute risk period, you probably need to aim for a harder target. 4Steven Byrnes20h Hmm, on further reflection, I was mixing up * Strawberry Alignment (defined as: make an AGI that is specifically & exclusively motivated to duplicate a strawberry without destroying the world), versus * "Strawberry Problem" (make an AGI that in fact duplicates a strawberry without destroying the world, using whatever methods / motivations you like). Eliezer definitely talks about the latter. I'm not sure Eliezer has ever brought up the former? I think I was getting that from the OP (Quintin), but maybe Quintin was just confused (and/or Eliezer misspoke). Anyway, making an AGI that can solve the strawberry problem is tautologically no harder than making an AGI that can do advanced technological development and is motivated by human norms / morals / whatever, because the latter set of AGIs is a subset of the former. Sorry. I crossed out that paragraph. :) 3Paradiddle1d One distinction I think is important to keep in mind here is between precision with respect to what software will do and precision with respect to the effect it will have. While traditional software engineering often (though not always) involves knowing exactly what software will do, it is very common that the real-world effects of deploying some software in a real-world environment are impossible to predict with perfect accuracy. This reduces the perceived novelty of unintended consequences (though obviously, a fully-fledged AGI would lead to significantly more novelty than anything that preceded it). [-]cousin_it1d O9153 As far as I can tell, the answer is: don't reward your AIs for taking bad actions. I think there's a mistake here which kind of invalidates the whole post. If we don't reward our AI for taking bad actions within the training distribution, it's still very possible that in the future world, looking quite unlike the training distribution, the AI will be able to find such an action. Same as ice cream wasn't in evolution's training distribution for us, but then we found it anyway. Reply 5StellaAthena1d I think there's a mistake here which kind of invalidates the whole post. Ice cream is exactly the kind of thing we've been trained to like. Liking ice cream is very much the correct response. Everything outside the training distribution has some value assigned to it. Merely the fact that we like ice cream isn't evidence that something's gone wrong.

I should just sit in a dark room to maximize my visual cortex's predictive accuracy."? I think I've been in situations where I've been disoriented by a bunch of random stuff happening and wished that less of it was happening so that I could get a better handle on stuff. An example I vividly recall was being in a history class in high school and being very bothered by the large number of conversations happening around me. Reply 5Lone Pine2d I think humans optimize for a mix of predictability and surprise. If our experiences are too predictable, we get bored, and if they are too unpredictable, we get overwhelmed. (Autistic people are particularly vulnerable to getting overwhelmed, but even NTs can get overwhelmed by too much stimulus.) In RL research, this is the explore/exploit tradeoff or the multi-armed bandit problem (terrible name). I think this also has something to do with the Free Energy Principle, but that would require understanding Karl Friston and no one understands Karl Friston. 5Quintin Pope2d I added the following to the relevant section: On reflection, the above discussion overclaims a bit in regards to humans. One complication is that the brain uses internal functions of its own activity as inputs to some of its reward functions, and some of those functions may correspond or correlate with something like "visual environment predictability". Additionally, humans run an online reinforcement learning process, and human credit assignment isn't perfect. If periods of low visual predictability correlate with negative reward in the near-future, the human may begin to intrinsically dislike being in unpredictable visual environments. However, I still think that it's rare for people's values to assign much weight to their long-run visual predictive accuracy, and I think this is evidence against the hypothesis that a system trained to make lots of correct predictions will thereby intrinsically value making lots of correct predictions. 3DanielFilan2d Note that Yudkowsky said which isn't at all the same thing as intrinsically valuing making lots of correct predictions. A better analogy would be the question of whether humans like things that are easier to visually predict.

It seems to me that there are grounds to doubt that based on how languages work. It still fails to predict our answers, regardless I suppose. 2DanielFilan1d It's pretty easily definable in English, at least in special cases, and my understanding is that GPT-4 fails in those cases. 1JavierCC15h (I suppose you know this) Ok, I say it because, from a semantic perspective, it's not obvious to me that there has to be a natural sense of wordhood. 'Words' are often composed of different units of meaning, and the composition doesn't have to preserve the exact original meaning unaltered, and there are many phrases that have fixed meaning that can't be derive from a literal analysis of the meaning of those 'words'.

You've provided an assertion with no argument or evidence. 5David Johnston16h Yes, because I thought the why was obvious. I still do! If doom has tiny probability, it's better to focus on other issues. While I can't give you a function mapping the doom mechanism to correct actions, different mechanisms of failure often require different techniques to address them - and even if they don't, we want to check that the technique actually addresses them. 2Gordon Seidoh Worley5h How large does it have to be before it's worth focusing on, in your opinion? Even for very small probabilities of doom the expected value is extremely negative, even if you fully discount future life and only consider present lives. 1David Johnston2h A quick guess is that at about 1 in 10 000 chance of AI doom working on it is about as good as ETG to GiveWell top charities 2Gordon Seidoh Worley1h So just to check, if we run the numbers, not counting non-human life or future lives, and rounding up a bit to an even 8 million people alive today, if we assume for the sake of argument that each person has 30 QALYs left, that's 8mm * 30 QALY at stake with doom, and a 0.01% chance of doom represents the loss of 24 thousand QALYs. Or if we just think in terms of people, that's the expected loss of 800 people. If we count future lives the number gets a lot bigger. If we conservatively guess at something like 100 trillion future lives throughout the history of the future universe with let's say 100mm QALYs each, that's 10^16 QALYs at stake. But either way, since this is the threshold, you seem to think that, in expectation, less than 800 people will die from misaligned AI? Is that right? At what odds would you be willing to bet that less than 800 people die as a result of the development of advanced AI systems? 1Tetraspace12m There are about 8 billion people, so your 24,000 QALYs should be 24,000,000.

(It would be surprising for Edison to not be thinking hard about what filament to use and pick tungsten; in actual history, it took decades for that change to be made.) 2Steven Byrnes21h Sure, but then the other side of the analogy doesn't make sense, right? The context was: Eliezer was talking in general terms about the difficulty of the AGI x-risk problem and whether it's likely to be solved. (As I understand it.) [Needless to say, I'm just making a narrow point that it's a bad analogy. I'm not arguing that p(doom) is high or low, I'm not saying this is an important & illustrative mistake (talking on the fly is hard!), etc.] 2Vaniver20h So I definitely think that's something weirdly unspoken about the argument; I would characterize it as Eliezer saying "suppose I'm right and they're wrong; all this requires is things to be harder than people think, which is usual. Suppose instead that I'm wrong and they're right; this requires things to be easier than people think, which is unusual." But the equation of "people" and "Eliezer" is sort of strange; as Quintin notes, it isn't that unusual for outside observers to overestimate difficulty, and so I wish he had centrally addressed the the reference class tennis game; is the expertise "getting AI systems to be capable" or "getting AI systems to do what you want"? -1Noosphere891d Basically, this is what I think happened to AI alignment, just replace ridiculously good heat resistant tiles with Pretraining from Human Feedback and the analogy works here. It wasn't inevitable or even super likely that this would happen, or that we could have an alignment goal that gets better with capabilities by default, but we found one, and this makes me way more optimistic on alignment than I used to be. 6Steven Byrnes1d I disagree but won't argue here.

Reply 5Noosphere891d The problem is that the even if the model of Quintin Pope is wrong, there is other evidence that contradicts the AI doom premise that Eliezer ignores, and in this I believe it is a confirmation bias at work here. Also, any issues with Quintin Pope's model is going to be subtle, not obvious, and it's a real difference to argue against good arguments + bad arguments from only bad arguments. 4dxu1d I think that this is a statement Eliezer does not believe is true, and which the conversations in the MIRI conversations sequence failed to convince him of. Which is the point: since Eliezer has already engaged in extensive back-and-forth with critics of his broad view (including the likes of Paul Christiano, Richard Ngo, Rohin Shah, etc), there is actually not much continued expected update to be found in engaging with someone else who posts a criticism of his view. Do you think otherwise? -2Noosphere8921h What I was talking about is that Eliezer (And arguably the entire MIRI-sphere) ignored evidence that AI safety could actually work and doesn't need entirely new paradigms, and one of the best examples of empirical work is the Pretraining from Human Feedback. The big improvements compared to other methods are: 1. It can avoid deceptive alignment because it gives a simple goal that's myopic, completely negating the incentives for deceptively aligned AI. 2. It cannot affect the distribution it's trained on, since it's purely offline learning, meaning we can enforce an IID assumption, and enforce a Cartesian boundary, completely avoiding embedded agency. It cannot hack the distribution it has, unlike online learning, meaning it can't unboundedly Goodhart the values we instill. 3. Increasing the data set aligns it more and more, essentially meaning we can trust the AI to be aligned as it grows more capable, and improves it's alignment. 4. The goal found has a small capabilities tax. There's a post on it I'll link here: https://www.lesswrong.com/posts/ 8F4dXYriqbsom46x5/pretraining-language-models-with-human-preferences [https://www.lesswrong.com/posts/8F4dXYriqbsom46x5/ pretraining-language-models-with-human-preferences] Now I don't blame Eliezer for ignoring this piece specifically too much, as I think it didn't attract much attention. But the reason I'm mentioning this is that this is evidence against the worldview of Eliezer and a lot of pessimists who believe empirical evidence doesn't work for the alignment field, and Eliezer and a lot of pessimists seem to systematically ignore evidence that harms their case. 2Stephen Fowler21h Could you elaborate on what you mean by "avoid embedded agency"? I don't understand how one avoids it. Any solution that avoids having to worry about it in your AGI will fall apart once it becomes a deployed superintelligence. I think there's a double meaning to the word "Alignment" where people now use it to refer to making LLMs say nice things and assume that this extrapolates to aligning the goals of agentic systems. The former is only a subproblem of the latter. When you say "Increasing the data set aligns it more and more, essentially meaning we can trust the AI to be aligned as it grows more capable, and improves it's alignment" I question if we really have evidence that this relationship will hold indefinitely. 2Noosphere8920h One of the issues with embedded agency is that you can't reliably take advantage of the IID assumption, and in particular you can't hold data fixed. You also have the issue of potentially having the AI hacking the process, given it's embeddedness, since there isn't a way before Pretraining from Human Feedback to translate Cartesian boundaries, or at least a subset of boundaries into the embedded universe. The point here is we don't have to solve the problem, as it's only a problem if we let the AI control the updating process like online training. Instead, we give the AI a data set, and offline train it so that it learns what alignment looks like before we give it general capabilities. In particular, we can create a Cartesian boundary between IID and OOD inputs that work in an embedded setting, and the AI has no control over the data set of human values, meaning it can't gradient or reward hack the humans into having different values, or unboundedly Goodhart human values, which would undermine the project. This is another Cartesian boundary, though this one is the boundary between an AI's values, and a human's values, and the AI can't hack the human values if it's offline trained. I disagree, and I think I can explain why. The important point of the tests in the Pretraining from Human Feedback paper, and the AI saying nice things, is that they show that we can align AI to any goal we want, so if we can reliably shift it towards niceness, than we have techniques to align our agents/simulators. 4dxu19h I don't see how the bolded follows from the unbolded, sorry. Could you explain in more detail how you reached this conclusion? 1Noosphere8911h The point is that similar techniques can be used to align them, since both (or arguably all goals) are both functionally arbitrary in what we pick, and important for us. One major point I did elide is the amount of power seeking involved, since in the niceness goal, there's almost no power seeking involved, unlike the existential risk concerns we have. But in some of the tests for alignment in Pretraining from Human Feedback, they showed that they can make models avoid taking certain power seeking actions, like getting personal identifying information. In essence, it's at least some evidence that as AI gets more capable, that we can make sure that power seeking actions can be avoided if it's misaligned with human interests. 2Stephen Fowler19h The first part here makes sense, you're saying you can train it in such a fashion that it avoids the issues of embedded agency during training (among other things) and then guarantee that the alignment will hold in deployment (when it must be an embedded agent almost by definition) The second part I think I think I disagree with. Does the paper really "show that we can align AI to any goal we want"? That seems like an extremely strong statement. Actually this sort of highlights what I mean by the dual use of 'alignment' here. You were talking about aligning a model with human values that will end up being deployed (and being an embedded agent) but then we're using 'align' to refer to language model outputs. 0Noosphere8911h Yes, though admittedly I'm making some inferences here. The point is that similar techniques can be used to align them, since both (or arguably all goals) are both functionally arbitrary in what we pick, and important for us.

I would in fact have preferred it if he had simply said nothing at all, in this particular case. Probably, deep down, I prefer that for some complicated social reasons but I don't think they're antisocial reasons and have more to do with the (fixable) rudeness inherent in the way he replied. [-]dxu1d 106 I also agree that the comment came across as rude. I mostly give Eliezer a pass for this kind of rudeness because he's wound up in the genuinely awkward position of being a well-known intellectual figure (at least in these circles), which creates a natural asymmetry between him and (most of) his critics. I'm open to being convinced that I'm making a mistake here, but at present my view is that comments primarily concerning how Eliezer's response tugs at the social fabric (including the upthread reply from iceman) are generally unproductive. (Quentin, to his credit, responded by directly answering Eliezer's question, and indeed the resulting (short) thread seems to have resulted in some clarification. I have a lot more respect for that kind of object-level response, than I do for responses along the lines of iceman's reply.) Reply 2lc1d That's reasonable and I generally agree.

To grapple with the intellectual content of my ideas, consider picking one item from "A List of Lethalities" and engaging with that. Reply [-]Quintin Pope21h 3314 To grapple with the intellectual content of my ideas, consider picking one item from "A List of Lethalities" and engaging with that. I actually did exactly this in a previous post: Evolution is a bad analogy for AGI: inner alignment, where I quoted number 16 from A List of Lethalities: 16. Even if you train really hard on an exact loss function, that doesn't thereby create an explicit internal representation of the loss function inside an AI that then continues to pursue that exact loss function in distribution-shifted environments. Humans don't explicitly pursue inclusive genetic fitness; outer optimization even on a very exact, very simple loss function doesn't produce inner optimization in that direction. This happens in practice in real life, it is what happened in the only case we know about... and explained why I didn't think we should put much weight on the evolution analogy when thinking about AI. In the 7 months since I made that post, it's had < 5% of the comments engagement that this post has gotten in a day. -\_(tsu)_/- Reply [-]habryka15h 2018 In the 7 months since I made that post, it's had < 5% of the comments engagement that this post has gotten in a day. Popular and off-the-cuff presentations often get discussed because it is fun to talk about how the off-the-cuff presentation has various flaws. Most comments get generated by demon threads and scissor statements, sadly. We've done some things to combat that, and definitely not all threads with lots of comments are the result of people being slightly triggered and misunderstanding each other, but a quite substantial fraction are. Reply [-]TurnTrout1d O9122 Here are some of my disagreements with List of Lethalities. I'll quote item one: "Humans don't explicitly pursue inclusive genetic fitness; outer optimization even on a very exact, very simple loss function doesn't produce inner optimization in that direction. This happens in practice in real life, it is what happened in the only case we know about, and it seems to me that there are deep theoretical reasons to expect it to happen again" (Evolution) - (human values) is not the only case of inner alignment failure which we know about. I have argued that human values themselves are inner alignment failures on the human reward system. This has happened billions of times in slightly different learning setups. Reply 9Elizabeth21h I imagine (edit: wrongly) it was less "choosing" and more "he encountered the podcast first because it has a vastly larger audience, and had thoughts about it." I also doubt "just engage with X" was an available action. The podcast [https://www.lesswrong.com/ posts/Aq82XqYhgqdPdPrBA/ full-transcript-eliezer-yudkowsky-on-the-bankless-podcast] transcript doesn't mention List of Lethalities, LessWrong, or the Sequences, so how is a listener supposed to find it? I also hate it when people don't engage with the strongest form of my work, and wouldn't consider myself obligated to respond if they engaged with a weaker form (or if they engaged with the strongest one, barring additional obligation). But I think this is just what happens when someone goes on a podcast aimed at audiences that don't already know them. [-]Vaniver21h 128 I agree with this heuristic in general, but will observe Quintin's first post here was over two years ago and he commented on A List of Lethalities; I do think it'd be fair for him to respond with "what do you think this post was?". Reply 8Quintin Pope21h Vaniver is right. Note that I did specifically describe myself as an "alignment insider" at the start of this post. I've read A List of Lethalities [https://www.lesswrong.com/posts/uMQ3cqWDPHhjtiesc/ agi-ruin-a-list-of-lethalities?commentId=GCnMqgmcYwwmcDEig] and lots of other writing by Yudkowsky. Though the post I'd cite in response to the "you're not engaging with the strongest forms of my argument" claim would be the one where I pretty much did what Yudkowsky suggests: My post Evolution is a bad analogy for AGI: inner alignment [https://www.lesswrong.com/posts/FyChg3kYG54tEN3u6/ evolution-is-a-bad-analogy-for-agi-inner-alignment] specifically addresses List of Lethalities point 16: and then argues that we shouldn't use evolution as our central example of an "outer optimization criteria versus inner formed values" outcome. You can also see my comment here [https://www.lesswrong.com/posts/ wAczufCpMdaamF9fy/ my-objections-to-we-re-all-gonna-die-with-eliezer-yudkowsky?commentId =wBvBzP2Gdono5w7m5] for some of what led me to write about the podcast specifically. 2Elizabeth19h Oh yeah in that case both the complaint and the grumpiness seems much more reasonable. 8lc1d The comment enrages me too, but the reasons you have given seem like post-justification. The real reason why it's enraging is that it rudely and dramatically implies that Eliezer's time is much more valuable than the OP's, and that it's up to OP to summarize them for him. If he actually wanted to ask OP what the strongest point was he should have just DMed him instead of engineering this public spectacle. [-]Garrett Baker1d 2426 I want people to not discuss things in DMs, and discuss things publicly more. I also don't think this is embarrassing for Quintin, or at all a public spectacle. Reply 6Noosphere891d I think that both of you are correct: Eliezer should have DMed Quintin Pope instead, and Eliezer hasn't noticed that actual arguments were given, and that it sounds like an excuse to ignore disconfirming evidence. This crystallizes a thought I had about Eliezer: Eliezer has increasingly terrible epistemics on AI doom, and a person should ignore Eliezer's arguments, since they won't ever update towards optimism, even if it's warranted, and has real issues engaging people he doesn't share his views and don't give bad arguments. 1Daniel 1d It does imply that, but it's likely true that Eliezer's time is more valuable (or at least in more demand) than OP's. I also don't think Eliezer (or anyone else) should have to spend all that much effort worrying about if what they're about to say might possibly come off as impolite or uncordial. I don't agree here. Commenting publicly opens the floor up for anyone to summarize the post or to submit what they think is the strongest point. I think it's actually less pressure on Quintin this way. 2Vaniver1d I have attempted to respond to the whole post over here [https:// www.lesswrong.com/posts/wAczufCpMdaamF9fy/ my-objections-to-we-re-all-gonna-die-with-eliezer-yudkowsky?commentId =ZS59FACSnWJfzLNGu]. [-]Quintin Pope2d 19-4 The "strongest" foot I could put forwards is my response to "On current AI not being self-improving:", where I'm pretty sure you're just wrong. However, I'd be most interested in hearing your response to the parts of this post that are about analogies to evolution, and why they're not that informative for alignment, which start at: Yudkowsky argues that we can't point an AI's learned cognitive faculties in any particular direction because the "hill-climbing paradigm" is incapable of meaningfully interfacing with the inner values of the intelligences it creates. and end at: Yudkowsky tries to predict the inner goals of a GPT-like model. However, the discussion of evolution is much longer than the discussion on self-improvement in current AIs, so look at whichever you feel you have time for. Reply 2Eliezer Yudkowsky2d You straightforwardly completely misunderstood what I was trying to say on the Bankless podcast: I was saying that GPT-4 does not get smarter each time an instance of it is run in inference mode. And that's that, I guess. [-]Quintin Pope2d 299 I'll admit it straight up did not occur to me that you could possibly be analogizing between a human's lifelong, online learning process, and a single inference run of an already trained model. Those are just completely different things in my ontology. Anyways, thank you for your response. I actually do think it helped clarify your perspective for me. Reply [-]Garrett Baker1d 158 I think you should use a manifold market to decide on whether you should read the post, instead of the test this comment is putting forth. There's too much noise here, which isn't present in a prediction market about the outcome of your engagement. Market here: https://manifold.markets/GarrettBaker/ will-eliezer-think-there-was-a-sign Reply 6jacquesthibs16h Even if Eliezer doesn't think the objections hold up to scrutiny, I think it would still be highly valuable to the wider community for him to share his perspective on them. It feels pretty obvious to me he won't think they hold up to the scrutiny, but sharing his disagreement would be helpful for the community. 2Garrett Baker15h I assume Rob is making this argument internally. I tentatively agree. Writing rebuttals is more difficult than reading them though so not as clear a calculation. 3Garrett Baker15h I also didn't want to make two arguments. One that he should use prediction markets to choose what he reads, and also he should focus on helping the community rather than his specified metric of worthiness. [-]307th1d 1324 Is the overall karma for this mostly just people boosting it for visibility? Because I don't see how this would be a quality comment by any other standards. Frontpage comment guidelines: * Maybe try reading the post Reply 2Garrett Baker15h LessWrong gives those with higher karma greater post and comment karma starting out, under the assumption that their posts and comments are better and more representative of the community. Probably the high karma you're seeing is a result of that. I think this is mostly a good thing. That particular guideline you quoted doesn't seem to appear on my commenting guidelines text box. 5Vaniver21h FWIW, I thought the bit about manifolds in The difficulty of alignment [https://www.lesswrong.com/posts/wAczufCpMdaamF9fy/ my-objections-to-we-re-all-gonna-die-with-eliezer-yudkowsky# The_difficulty_of_alignment] was the strongest foot forward, because it paints a different detailed picture than your description that it's responding to. That said, I don't think Quintin's picture obviously disagrees with yours (as discussed in my response is over here [https://www.lesswrong.com/posts/wAczufCpMdaamF9fy/ my-objections-to-we-re-all-gonna-die-with-eliezer-yudkowsky?commentId =mATAbtCtkiKgAcn8B]) and I think you'd find disappointing him calling your description extremely misleading while not seeming to correctly identify the argument structure and check whether there's a related one that goes thru on his model. 1the gears to ascension15h dude just read the damn post at a skim level at least, lol. If you can't get through this how are you going to do... sigh. Okay, I'd really rather you read QACI posts deeply than this. But, still. It deserves at least a level 1 read [https://www.lesswrong.com/posts/ sAyJsvkWxFTkovqZF/ how-to-read-papers-efficiently-fast-then-slow-three-pass] rather than a "can I have a summary?" dismissal. -8lc1d [-]qvalq1d 00 Randomly adding / subtracting extra pieces to either rockets or cryptosystems is playing with the worst kind of fire, and will eventually get you hacked or exploded, respectively. Haha. Reply [-]Muyyd1d 00 DeepMind can't just press a button and generate a million demonstrations of scientific advances, and objectively score how useful each advance is as training data, while relying on zero human input whatsoever. It can't now (or it can?). Is there no 100 robots in 100 10x10 meters labs trained with recreating all human technology from stone age and after? If it is cost less than 10 mil then they probably are. This is a joke but i don't know how offtarget it is.
