The destruction of the labour theory of value has been a goal of "tech" for a while, but if they achieve it, what's the plan then?
Assuming humans stay in control of the AIs because otherwise all bets are off, in a case where a few fabulously wealthy (or at least "onwing/controlling", since the idea of wealth starts to become fuzzy) industrialists control the productive capacity for everything from farming to rocketry and there's no space for normal people to participate in production any more, how do you even denominate the value being "produced"? Who is it even for? What do they need to give in return? What can they give in return?
