I think we already do, at least for many people. AI-generated stuff reduces the value that humans put on human creation because human-only creation is harder to find. AI takes the joy of discovery out of many processes and activities. It's of course harder to get jobs in creative fields now such as translation and graphic design. It's a devaluing of creativity and it's discouraging to quite a few creatives. The very fact that many artists already feel depressed about AI is already itself a huge negative impact on creativity.
I can't tell you how many people have told me how depressed they are about AI and how they have less impetus to create things. Although one can certainly do it still for joy, it's harder for many in an environment that is so ruthless.
On top of "hard to find" I think it also displaces the market for real art, there are lots of blogs (or splogs?) like this one that are full of AI slop art, like this one
maybe the whole article is AI generated, but the second image from the top is just awful. If people get the idea that crap like that is acceptable, how can anybody sell real work?
so far as I can tell and the AI generated image on it is actually pretty funny and it really problematizes the idea that you could sell art to that kind of market.
