I'd consider brains and other biological neutral systems as neutral nets. So to me there's pretty convincing evidence that neutral nets can form an AGI

Well you shouldn’t. They are not the same. Brains are not (ML) neural networks. Neural networks are just a mathematical approximation of one part of how the mind works

I never ever said that the tiny approximation of subsets of our brain was enough for AGI. Just because we haven't found out the exact structures of the neural net in our brain and how to emulate it, it's still very much a neural net. It's just bigger and more complex than anything we can make our emulate yet.
