> An AI could make something look like a Picasso, but it could never invent cubism.

I wouldn't bet on this

"Never" and "AI" in the same sentence requires a high level of confidence in a specific future. I don't see why AI of the future couldn't generate a mind with all of the complexity and life experience (simulated) that Picasso was inspired by. Do that a trillion times and we might get things even cooler than cubism.

Could an AI, and some selective process (think YouTube algorithm) over billions of iterations evolve cubism?
