|
| Right. LLMs don't 'think' like people do, but they are doing
| _something_. At the very least, it can be called information
| processing.* Unless one believes in souls, that 's a fair
| description of what humans are doing too. Humans just do it
| better at present.
|
| Here's how I view the tendency of AI papers to use
| anthropomorphic language: it is primarily a convenience and
| shouldn't be taken to correspond to some particular human way
| of doing something. So when a paper says "LLMs can deceive"
| that means "LLMs output text in a way that is consistent with
| the text that a human would use to deceive". The former is
| easier to say than the latter.
|
| Here is another problem some people have with the sentence
| "LLMs can deceive"... does the sentence convey _intention_?
| This gets complicated and messy quickly. One way of figuring
| out the answer is to ask: Did the LLM just make a mistake? Or
| did it 'construct' the mistake as part of some larger goal?
| This way of talking doesn't have to make a person crazy --
| there are ways of translating it into criteria that can be
| tested experimentally without speculation about consciousness
| (qualia).
|
| * Yes, an LLM's information processing can be described
| mathematically. The same could be said of a human brain if we
| had a sufficiently accurate enough scan. There might be some
| statistical uncertainty, but let's say for the sake of
| argument this uncertainty was low, like 0.1%. In this case,
| should one attribute human thinking to the mathematics we _do
| understand_? I think so. Should one attribute human thinking
| to the tiny fraction of the physics we can 't model
| deterministically? Probably not, seems to me. A few
| unexpected neural spikes here and there could introduce local
| non-determinism, sure... but it seems very unlikely they
| would be qualitatively able to bring about _thought_ if it
| was not already present.
| deadbabe wrote:
