We already live in a time of artistic stagnation. With how much audio engineers manipulate pop music in Pro Tools, "fake" singers have been a practical reality for 20 years. Look at Marvel movies. Go to any craft fair on a warm day, or any artists' co-op, in a major city and try, try to find one booth that is not exactly like 5 other booths on display.
People have been arguing about what is "real art" for centuries. Rap music wasn't real because it didn't follow traditional, European modes and patterns. Photography wasn't real because it didn't take the skill of a painter. Digital photography wasn't real because it didn't take laboring in a dark room. 3D rendering wasn't real. Digital painting wasn't real. Fractal imagery wasn't real. Hell, anything sold to the mass market instead of one-off to a collector still isn't "real art" to a lot of people.
Marcel Duchamp would like to have a word.
If anything, I think AI tools are one of the only chances we have of seeing anything interesting break out. I mean, 99% of the time it's just going to be used to make some flat-ui, corporate-memphis, milquetoast creative for a cheap-ass startup in a second rate co-working space funded by a podunk city's delusions they could ever compete with Silicon Valley.
But if even just one person uses the tool to stick out their neck and try to question norms, how can that not be art?
