They might, but my read on human psychology over civilization is that there needs to be a system in place to incentivize it. Fortunately I'm not in charge of anything, all I can do is blather about things on the Internet.
UBI doesn’t mean a money-less society; it just means you won’t just die or go into debt if you lose your job. I imagine most jobs would still exist and continue providing the same incentives for those who want to pursue them.
