I'm quite sure that LLMs are not one-to-one with our brains. It would at least be surprising if instrumental convergence was that powerful, and, even in that case, they're still not getting hungry or sleepy or having dreams, etc. At best they'd match up with a smaller region of our brains, and I'd take 9:1 odds against a close match.

But the paper argues a much stronger point than "LLMs are not similar to human brains": it claims LLMs cannot engage with meaning because they model human language instead of sensory input or human thought.

I also don't think human brains are particularly deterministic.
