Well obviously he'll have the AI 'dispose' of the poor and live a life as a king with a select few farmed humans and have the world as a play thing.
Really the entire future of AI at this point seems like "Don't worry about it, we'll figure out when we get there". Works a lot better if you're extremely rich and can afford your own private security.
I never understood why people setting up bunkers expect the security to still be loyal after whatever happens.
