More relevant is: what if only the wealthy own all the AI and robots? They already own all the trees, but they don't own the people necessary to harvest them and make stuff out of it. With strong AI, they will also own all labout, all production capacity, and all ability to maintain it; they won't need anyone else anymore. Middle and working class people will have become obsolete.

Unless we change our economy to have a more equal distribution of wealth before we get there.
