That's where we are getting, but what people, especially on the top don't want to see. If nobody makes money, except selected few, who does the capitalism then?
If the money holders no longer need plebs for anything because AIs can do it all, what role do the plebs play? Why give them any of the money, and therefore what value has money?
Are they reduced to say gladiators and pornstars, observed for entertainment by the AI-owning class, in exchange for enough food to live
There's only 1 billionaire for every what, 10M people, 100M ? They are outnumbered. At some point the underclass may band together and kick off a revolution to overthrow the ruling class.
Kings have gotten their heads chopped off when the people had enough.
I can see a version of history where the end of capitalism was AI and the AI-owning class with their robots and capital essentially dispose of the majority of the society. Society decides this system is screwed and decides to overthrow capitalism and we invent a new system.
After all, at some point, smart people came up with capitalism to solve the previous system's problems. We may not go to socialism but invent something new entirely to address the flaws of late stage capitalism.
