And how exactly does a nation $39 trillion in debt PROVIDE this UBI, when we are told Social Security itself is "endangered"? Only massive taxes on the rich could make a dent, and then they will just leave the U.S.
That said, the capex of the tech world is about to make a leap that is unimaginable. They will be able to pay this UBI. That's why Elon says this.
What Elon doesn't understand is humans cannot be bought off with UBI. He is the perfect example of someone who is very smart in one thing, and dumb as a rock in others (i.e., Elon is a genius at understanding tech, but an idiot at understanding basic human motivation).
IMHO, UBI will not work. Elon is stupid to think it will.
