Another thing to notice here is that Musk’s world view is consistently “rich gets richer” and, naturally, his premise on the UBI is the same: the rich will take away the jobs thanks to AIs. The ordinary will be on the UBI instead. We’re gonna fuck you, and you don’t fly away.
If he really cared about the ordinary, he’d not treat joblessness as inevitability in his argument. Because it’s him who has the power to make the ordinary richer, and he doesn’t engage on that at all. No way. No way he actually cares about the ordinary in his UBI argument.
