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!)
