       | If the model comes up with anything even remotely correct it

               | easily verified by our capability to address problems

               |

               | concepts using approximate, distributed representations,
               | and it's also possible to follow a rigid procedure with
               | near-zero understanding (e.g., executing steps
               | mechanically without grasping place value).
               | 
               | So if the claim is "LLMs don't manipulate concepts
               | because they don't implement the grade-school algorithm,"
               | that's just conflating one particular human-taught

               | lead to) novel concepts. The first one is a huge area,
               | better understood than the second though still
               | characterized more by what we don't know than what we do.
               | Nevertheless, it is there that the most obvious parallels
               | with e.g. the Lindsey papers can be found. Neural
               | networks, activation networks and waves, signalling etc.
               | etc. The brain receives (lots of) inputs, generates
               | responses including but not limited to speech generation.
               | It seems entirely reasonable to suggest that _maybe_ our
               | brains, given a somewhat analogous architecture at some
               | physical level to the one used for LLMs, might use
               | similar mechanisms as the latter.
               | 
               | However, nobody would say that most of what the brain
               | does involves manipulating concepts. When you run from
               | danger, when you reach up grab something from a shelf,
               | when you do almost anything except actual conscious
               | reasoning, most of the accounts of how that behavior

               | No. There's a huge difference between behavior and

               | (even though that's really a concept, but that detail is
               | not worth arguing about here), but that describes, as you
               | note, a goal not a mechanism. Along the way, they
               | manifest huge numbers of sub-goal directed behaviors (or,
               | one could argue quite convincingly, goal-agnostic
               | behaviors) that are, broadly speaking, not governed by

               | 
               | (1) - A major part of the challenge is in not being
               | directed towards something. There was no external
               | guidance for Einstein - he wasn't even a formal

               | anything relevant, even with substantially greater
               | precision specifying field/subtopic/etc.
               | 
               | (2) - Logical processing of natural language remains one
               | small aspect of intelligence. For example - humanity
               | invented natural language from nothing. The concept of an
               | LLM doing this is a nonstarter since they're dependent
               | upon token prediction, yet we're speaking of starting
               | with 0 tokens.
               | 
               | (3) - LLMs are, in many ways, very much like calculators.
               | They can indeed achieve some quite impressive feats in
               | specific domains, yet then they will completely
