There is nothing "clear" about this. All we know is that the neural nets arrived where they are today, not by billion years of evolution, but by getting training on artifacts that resulted from those billion years of evolution. Does that mean they are the same or fundamentally different? How about we just admit that we don't know? Instead we pull out the "human exceptionalism" card again, which generally had a terrible track record throughout history, and helps absolutely nothing in gaining understanding.
