It's not one way consumer just like humans are not. It can direct long term evolution of reason. For starters it can be used to denoise/dedup/optimise training set to be closer to optimum (to create smaller "copies" of itself).

There are instances of things that happened (history, what Paris Hilton did say on 22nd of April etc, big database of mostly irrelevant facts) and truths (math, physics, chemistry etc) where AI can enhance discoveries by helping us to see what we have not yet realised.

Both seem endless tbh but personally I'm more interested in latter.
