Who owns the AI, demanding payment for its use? Who owns the GPUs that the AI runs on? Who sold those people the silicon? Who owns the real estate upon which the GPUs run? All those people will demand payment for services rendered or goods delivered.
My personal favorite: Who fixes the AI when it breaks?
The lawn mower replaced human work, but it needs _just enough_ direction that it's still worth money for humans to run them, auto-run lawn mowers notwithstanding.
AI will make people faster, but humans will only do work for other humans that do their share by giving value back.
I don't believe we will ever live in a world where people won't want people working for them, or doing something for them.
