Artists who are put in danger by AI-generated art:
Anybody who exclusively makes "stock image" art or vague high-level concept art.
Artists who are NOT put in danger by AI-generated art:
Anybody who makes specific artwork and direct requests from clients (i.e., most artists)
Not to power level, but I work as an artist and I've been examining this stuff for a while now to see what it will do to my job. The result I've landed on is "not much", and it has actually already made my job easier. If somebody needed a generic "spooky forest" for a backdrop in a slide presentation, they no longer need to hire an artist for that. However, if they need art of a specific character doing a specific thing (like for video game or movie concept art) they absolutely still need a real life artist for that. Long story short: If a google image search or stock image can satisfy your need for art, AI generation can handle it.
I've tried for hours to recreate existing characters via AI, and while the results are fun, I can never quite get what I want. It's essentially a fan art generator in that regard. All this could change in ten years when things improve and image repositories get larger, but for now I don't feel threatened as an artist yet.
