UBI might solve rent, would it solve "relevancy"? There are genres of art where the means of production became so easy/cheap that the world is flooded with them, I recall reading a blog from some years ago discussing how EDM music had become so cheap and easy to produce that the market was flooded with content which fewer and fewer people would actually pay for.

UBI might give people the opportunity to explore their interests but ultimately wouldn't you end up in the same place? Torn between a desire to make "art" which suddenly everyone else is also trying to make and follow their passion, or get paid substantially more for UI Development?
