They will cater more and more to each other until they turn inward and start hoarding and rearranging resources into their compartmentalized cocoons while they attempt to transform their empires into launch pads that will let them escape the planet like some sort of fungal spore to infect and consume another world.
They will fail to develop a way to sustain humans off world and will leave behind a polluted hellscape of toxic nonsense and dysfunction.

I hope someone still has the resources to pour concrete over the entrances of these billionaire fallout shelters when the front finally falls off the whole yacht.
