I'd distinguish between physical art and digital art tbh. Physical art has already grappled with being automated away with the advent of photography, but people still buy physical art because they like the physical medium and want to support the creator. Digital art (for one off needs), however, is a trickier place since I think that's where AI is displacing. It's not making masterpieces, but if someone wanted a picture of a dwarf for a D&D campaign, they'd probably generate it instead of contracting it out.
Right, but the question then is, would it actually have been contracted out?
I've played RPGs, I know how this works: you either Google image search for a character you like and copy/paste and illegally print it, or you just leave that part of the sheet blank.
So it's analogous to the "make a one-off dashboard" type uses from that programming survey: the work that's being done with AI is work that otherwise wouldn't have been done at all.
