Would they always need earth to be habitable?
Because if they somehow managed to terraform and colonise another planet like mars, wouldnt they just make earth so uninhabitable that the rest of us would be forced to go where they are? (Prolly as slaves)
While I’d argue in practice there is a pretty significant difference in capability between household labour, advance materials refinery, and workforce management for the sake of this argument we are obviously assuming hyper advanced robotics and in that case you’re 100% right.
However, going back to my argument of “if they can replace all labour with robotics”: in that kind of situation, what’s to stop us from making more until every job is covered by robotics?
Then none of us need to work, and the entire concept of a billionaire becomes irrelevant.
And who even cares if a couple thousand people decide to leave with some robots? They still won’t be able to bring the majority of their wealth and in that case all the more for us left on earth.
well now you add in robotic soldiers and who makes them first and if they are the type that feel large sections of the world are their private property.
