That is assuming this is purely about economics. It may well not be; for example, if art is humanity’s version of peacock tails, then the effort is the point, and if so, then even an uploaded brain of some famous and well-regarded artist will be dismissed as “not capable of real art”[0].
Hobbies for social experience can certainly still be a thing, as evidenced by the fact that art clubs and music clubs survived the invention of recorded music and photography respectively.
Even code has forms of this: challenge devs to write games in 1k, or on old hardware, or code golf.

Bunch of artist or creative people don't do it "because of the job", they do it for fun and reason that they like drawing, writing, programming etc. There is a lot of artist and writers who live in poverty all their lives. They could stick to their manual labor that provides food and get drunk, watch TV series in their free time but many people still go above and beyond that anyway.
There are of course many people who already have "why go to school, why even bother" attitude and somehow they are still alive waking up in the morning and going to work or whatever else they are busy with.
I don't really attach any significance to employment in the sense of doing work directed by someone else to make profits for some business in order to get more money. It might be a personality trait, but I don't really want or need more money and I hate being told what to do.
However- I have a ton of ideas and side projects and musical and art projects I'm always working on, and those things aren't done for pay, but they are work in the sense that they required sustained, focused effort. And that's hard even if you love what you're doing. And it sure helps if what you are creating is something that other people will appreciate when it's done, and I fear that if an AI can generate something ten times better with no effort at all, then it might start feeling pointless to do all those things. Self motivation will sustain you for a while, but external validation helps a lot after a certain point.
Seems to me like we should reward people for achieving sustainability rather than only rewarding growth.
Maybe it's time to start substituting a bit of competition with a bit more collaboration and looking out for the needs of everyone? Just a thought.
