Unless your two hands are building murderbots, though, it doesn't matter what you're building if you can't grow or buy food.

I haven't personally seen how UBI could end up working viably, but I also don't see any other system working without much more massive societal changes than anyone is talking about.

Meanwhile, there are many many people that are very invested in maintaining massive differentials between the richest and the poorest that will be working against even the most modest changes.
