But you answer your own question: the only situation in which it makes no sense to hire another person to satisfy a need is when that need has already been satisfied in another way.
And if all needs are already satisfied... Why worry about work? The purpose of work is to satisfy needs. If needs are satisfied, there is no need for work.
You assume the everyone's needs are solved together. More likely is that the property owning class acquire AI robots to provide cheap labor; and everyone else doesn't.
>You assume the everyone's needs are solved together.
No, I am not assuming that. "Together" are not required. It's just combination of needs, ability to satisfy them and ability to exchange - creates jobs. And nothing of this will be thwarted by AI.
>More likely is that the property owning class acquire AI robots to provide cheap labor
Doesn't matter. Your everyday person either will be able to afford this cheap AI labor for themselves (no problem that required solving) or if AI labor for them are unaffordable - will create jobs for other people (there will be jobs on market everywhere)
