He has a point, certainly. But while he is harping about the U part of ubi, he's completely ignoring the B part. UBI is meant to provide some basic income so people don't starve. It's just an optimization of welfare programs where you have a ton of bureaucracy and make people jump through endless hoops and cause them endless amounts of stress (which is known to make people work less, not more). And replace it by just giving all citizens the same amount.
Yes, that's a bit stupid for the people first paying taxes and then getting them right back again minus overhead costs, but if you think about it: that's what happens now too, only less efficient (in the netherlands, that is) so you pay even more overhead.
On top of that comes the other realization: If the current trend of automating everything continues,we'll ultimately end up with (hyperbole) 1 person owning all the machines doing all the work. That 1 person earning all the money, and (in an ideal case) paying his taxes to give everybody else welfare. Which just is the same as UBI.
In a certain way this already happens now. Most not-too-smart people that used to be gainfully employed as laborer somewhere are now on welfare, and the threshold for not-too-smart could go up rather steeply with the current AI trends.
