Just doing nothing isn't great for the "human spirit", but UBI doesn't mean people can't find their own goals to pursue. The idea of something where people are not longer required to work to survive is hard to accept since many people haven't seriously considered how they could meaning outside of their careers

I see two alternatives, one that people find new ways to do productive work with or in the presence of LLM, or massive social unrest, rebellion, war and/or starving to death, followed by a reset. I.e. the way human nature has responded to similar imbalances in the past.
