So we're in a very good position to say quite a lot about the brain, an incredible amount really. And that puts us in a very good position to say that our brain is very different from other animal brains, and certainly in a very good position to say that's very different from an LLM.
Now, you can argue that an LLM is functionally equivalent to the brain, but given that it's so structurally distinct, and seemingly functions in a radically different way due to the nature of that structure, I'd put it on you to draw symmetries and provide evidence of that symmetry.
