Capitalists don't care about money. Capitalists collect money for it's power in a capitalist system.

If they get "AI" and industrial robots, they don't care that nobody can buy their products anymore because they never cared about selling products in the first place.

Right now capitalists loathe that they can "only* collect a 10-50% return on the things "they build", and the rest of the value has to go to the consumer. They want nothing more than getting rid of that "waste", and just having their personal factories create whatever they want and their personal farms making whatever they want and we all just fucking die.
