I feel like AI art promises the ability to raise the baseline art available for people who want some artwork for some purpose from stick figures drawn in MS paint to something reasonably artful. The sort of things that would previously have been filled by a Google image search, ripping something off deviant art or just browsing a stock images / clip art website until you find something “good enough”. I think part of the problem with AI art discussions is we do these side by sides with “real art” while glossing over all the places where “art” is used all the time and doesn’t need to rise to the level of “something that will be displayed in a museum”.
