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.
