The reason that this won't work in the end is that they will reduce headcount once they understand the technology and then we'll be hanging out permanently. Factory workers didn't get extra time in the break room when robots were implemented to speed up the assembly line. They got replaced permanently.
That's potentially a good thing in the long run. People can do either higher-skill work and/or we'll reorganize society to account for less people working.
I think that's a little naive. We could do it now in the US but we don't. In countries like the US I expect widespread poverty after more jobs evaporate, because the wealthy won't want to just support those people, even if we can as a country. We won't need all those hourly workers to do basic things. But what will all those people who don't have a "real job" that does something a robot/ai can't perform do? The US will have chaos and maybe even actual fighting before the federal legislature approves UBI.
That is possible, but I feel like usually we take the middle-of-the-road approach later than we should. So it won't be an optimal transition but it will be OK. I'd advocate for figuring it out sooner and more generously though!
