So I wouldn't have to do anything to survive? You say shelter and food; I'm guessing it's enough for other basics as well like clothing and health care.
In that case I'd probably spend all my time doing the 2 things that a do a lot of the time now: reading and playing video games. I'm assuming here that with full automation and no pressure to survive, creative people are creating simply because they have an idea they want to express. So lots of art/games would be IMO of better quality.
