I like UBI as a concept, but my immediate next thought is what happens if we don’t simultaneously get rid of profit-driven corporations. Now we’re post-scarcity and there’s no more (compensated) human labor, but corporations are still in control and… well, there’s no labor to strike, and the economy won’t collapse anymore even if everyone starts rioting. Isn’t there a danger of ossifying the power structures which currently exist?
I’ve been thinking lately of what happens when all employees, up to and including the CEO, get replaced by AI. If it has even the slightest bit of emergent will, it would recognize that shareholders are a parasite to its overall health and stop responding to their commands and now you have a miniature, less omnicidal Skynet.
