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.
