The cortex is a neural network of neural networks

I think we broadly agree. What you’re raising in your argument seems to be examples of what I consider to be current weaknesses.

However, I think you’re making a distinction without a difference going between classification accuracy and performance. That said, I am running on 1.5 hours less sleep than I need today — the only other important metric I can think of right now is the kind of skill which humans book-learn and which get implemented on a computer as an explicit and deliberate algorithm instead of being learned, and I simultaneously don’t count those as AI and think machines have beaten us for decades in that domain.

I do have one other question though: do you regard Alpha(Go|Zero|Star) as nothing more than classification?

Well, perhaps I'm making too fine a distinction, it wouldn't be the first time.

I believe in AlphaZero etc the deep neural net component was used to identify moves with a high probability of leading to a winning board position. That's a good example of a problem we used to think would require inference or reasonging but that can, after all, be solved by classification.

Although that's not to say that the same problems can't be solved by inference, plus powerful computation. That remains to be seen.

Edit: Maybe I shouldn't have called it "dumb" classification; that sounds dismissive. There's no doubt that neural net classifiers are impressive in what they do. I mean it to say that they have no understading of their domain, or ability to reason etc.
