This is just a semantic debate on what counts as “similar”. It's possible to disagree on this point despite agreeing on everything relating to how LLMs and human brains work.

Hence, my question is "how does the human brain work?" Nobody really knows, therefore we can't know if LLMs actually work in a similar way. It's a big point of the author in the paper, it's a big reason why it is so inappropriate to anthropomorphize LLMs.
