Quants have made billions predicting changes in valuations. Once it's predictable it shortly thereafter becomes gamed, of course. Algorithmic trading is all trolls trolling trolls these days. But predicting future trends absent market reaction to that very prediction is certainly something software can do, regardless of the terminology.
AI will exist only when we've finally shifted the definition far enough to allow non-AI to be classified as AI.
That stuff you're calling "non-AI" is what AI researchers call "AI". AI is not the quest for machine consciousness - who wants that anyway? AI research is the field that solves problems that seemed at first glance to require consciousness to solve. One of the founders of the field once complained that, to the public "AI is the set of all the problems we haven't solved yet". Pretty much what you just said. But it's the field of AI that solves these "suddenly not AI" problems, and that's always been their goal.
