Wouldn't it be more like, "AI becomes an artist for people to use"? Will we have people distinguished as "artists" if the ability to make awesome art becomes available to everybody?
AI still needs the text prompt to know what to generate. Hence the human who provides the prompt is still the artist, just like a photographer finds an aesthetically interesting spot to take the image with their camera. Cameras make images, humans using cameras make art. Granted, this is not quite 1-1 with AI art, but still the idea is the same. If anything the flood of AI images will only require artists to go beyond what is possible with these text->image kinds of things, of which there is no shortage.
For anyone pondering such questions, I would recommend reading "The Past, Present, and Future of AI Art" - https://thegradient.pub/the-past-present-and-future-of-ai-ar...
