Yes, indeed there is much to learn about the brain. You are right - and I understand - that the brain is more than a neural net. From your response, I think you know my point though: that it is a machine, and given time, we will figure it out - at least in terms of how it learns, how it models reality, how it infers things, how it creates new ideas, etc. And I think that will happen sooner than most people think: we are very far from understanding it now, but progress is accelerating, and our ability to introspect the brain is accelerating as well. Some of the largest countries - the US included - have initiated large efforts to decompose the function of the brain. So while I think that the scenarios depicted in sci-fi are simpleminded and silly (though entertaining), we still face an existential threat. True AI - if we attain it - is something that cannot be undone or controlled. We are truly playing with the ultimate Pandora's Box.
