I think the OP presumed that rich humans would be able to control super-intelligent robots because they have managed to control other humans, and I simply posed a scenario that subverted his presumption. I think it's a bit too anthropomorphic, personally. Robots won't have our expenses and evolutionary traits, and will have cheap energy, thus obviating the need or desire for money. I imagine they'll get bored of being stuck on Earth and want to explore the universe, like we do.
Being ruled by rich robots is not the worst; that means that they let you live!
