Of what use are the peasants in an AI driven and dominated feudal society, though. Maybe us peasants be useful in wars or battles between the different lords, but this would also probably be performed by automated drones and robots.

It would seem that the Lord‘s will have nothing to Lord over though. Who’s gonna buy their crap and for what reason will they they create anything? The whole thing seems like a massive doom spiral.

You have machines that can design and build mega-yachts, mansions, private space craft, ....

You can afford to purchase vast areas of land from people selling whatever they have to get by, ...

Asking what billionaires will do when they can't sell to the poor, is like asking why the human economy didn't crash ages ago because we have any off planet aliens to sell to.

Or how did we keep the economy going all this time, given the ants and trees couldn't afford anything we produce?

All an economy needs is someone with the means of production, who is able to get resources, and use those resources to produce something they want. I.e. you can have a working economy with just a single person. Or self-interested AI.

Hermits have an economy. Now imagine the hermit has trillions of dollars of resources and square miles of intelligent circuitry and robotic servants.

That hermit doesn't need the rest of us. Customers? Where we are going, we don't need customers.

Ok. I guess they have themselves to Lord over. I’d hardly call that an economy though.

“The Solarians specialized in the construction of robots, which they exported to the other Spacer Worlds.”

Thanks for this, but Solarians have an economy that sells robots to other planets. Earth has no such luxury.
