I think I'd feel a bit less anxious in general, knowing the worst that
   could happen is living in good comfort. I think 30k per person is too
   much though, 15k is really quite enough (at least in NL). This also to
   prevent complete perversion of reward-for-labor.
   I think the "digital nomad"-compatible family of jobs will lose their
   associated risk (if it doesn't work out, you're still fine) and that
   will help them. Jobs that are highly paid will likely still be pretty
   rewarding, too. It's the jobs that pay little now that get the serious
   change in their economics. Who wants to pick up garbage for almost no
   money, when you have enough money?
   It is also hard to estimate how many people will prefer entirely
   useless work, or a minimal lifestyle. Given a tease more automation
   that should not be a problem. But, remember, as automation increases
   the basic income can become less; as a certain level of comfort is
   achieved at a lower price. This also gives governments some new and
   interesting incentives.
   The gamble sometimes seems to be whether some "successful creative and
   risky business" produces more value than "cheap labor". (And, well,
   what those lousy-job-people will do when they get a lot of time on
   their hands!)
