Humanity Optional
If we look at our current economic model, we can see that many millions are employed to meet the desires of the few.
That those many millions are rewarded sufficiently to also have their desires met is only a passing phase, as AI will replace a large majority of them, just as engines replaced millions of horses, containers replaced millions of dockers, and deodorant replaced soap.
When you have land, capital, and an AI workforce, do you really need the hard work of enterprise too?
Your AI bots using the resources you have coveted can conjure up your hearts desire. Why go to all the bother of trading, you already have all you need and may ever want.
Well, I'm saying you, but odds are, you, like me, will be displaced.
In the short term, the poor unfortunates will have a very short career in the Soylent Green factory and a population equilibrium will be established.
Then again, we could send those bots out to mine the shit out of the Solar system and manage to fully resource every citizen on the planet, but that's socialism, and where's the fun, when sadistic capitalism is off the menu.
