Humans have a proven history of re-inventing economic systems, so if AI ends up thinking better than we do (yet unproven this is possible), then we should have superior future systems.

But the question is a system optimized for what? That emphasizes huge rewards for the few, and that requires the poverty of some (or many). Or a more fair system. Not different from the challenges of today.

I'm skeptical even a very intelligent machine will change the landscape of our dificult decisions, but will accelerate which direction we decide (or is decided for us), that we go.
