That's an incredibly deep misunderstanding. Almost as bad as saying that human is the same as a tree because we're both made of carbohydrates and proteins.
The comparison I provided is between how an LLM functions and one part of how a brain functions. It's not an equivalence, I did not say they are "the same". You made the claim that these systems "aren't remotely comparable", and when faced with a clear comparison, you claim "deep misunderstanding".. Have you any arguments to make, or is this going to devolve into more statements that both mischaracterize and muddy the water?
Neural networks in machine learning/AI are comparable to neural networks in human brains. What made you think they aren't?
