If you believe that physics describe the rules by which the universe operates, then there's literally nothing in the universe a large and fast enough computer can't emulate.

Cyborg c.elegans seem to behave just like the biological version: https://www.youtube.com/watch?v=I3zLpm_FbPg

Intuition is a guess based on experience. Sounds an awful lot to me like what LLMs are doing. They've even been shown to rationalize post-hoc just as Humans do.

Humans have incorrectly claimed to be exceptional from all of creation since forever. I don't expect we'll stop any time soon, as there's no consequence to suffer.

It's perfectly obvious to me that physics (excluding quantum physics which is scratching the surface) can't describe consciousness. If it could, it would have by now.
