(Visual) artist, here.

In art school they (responsibly, I thought) told us "it's very difficult to survive as an artist", so:

a.) Go to grad school and become a teacher b.) and/or, Become good at writing grants c.) and/or Don't quit you day job

Seeing all the hoo-ha about (visual) artists getting all up in arms about AI, my opinion is: if are you actually creative, not just concatenating things from "inspiration" web sites, then don't worry too hard. You'll find new questions to answer and new media to answer them in.

wrt musicians, I'll give any music try, ai or not. I'd be less interested in buying swag or seeing live performances of ai, and know a LOT of musicians who do it for love, so don't see them drying up altogether.
