Yes, what will all the psychos do if they don't have companies to run?
I've been meaning to refer to Michael Moorcock's 'Dancers at the End of Time' novels and short stories in relation to AI. The remaining human population was fixed at a very small number, had infinite resources at their immediate disposal and spent all their time amusing themselves. There's no discussion of technology other than references to mysterious cities that are toxic to humans. The humans had no need to deal with them. Presumably if AI becomes advanced enough that it can extract and manage resources, build and fix its own devices and produce whatever we want or need then we could approach this state. Don't know what that would mean for humanity though, we'd be pointless, there'd be nothing to strive for or debate. Politics and economics would be meaningless.
