I can guarantee you that some actual artists are using AI as a tool that complements the human mind. You can feed your sketches or finished work into it (image-to-image) to generate more details, and the best AI art seen today often involves an digital artist cleaning up the AI mistakes by hand (Photoshop).
But in general, the artistically unskilled/uninclined are having their human creativity amplified by AI. People have ideas, and now they can make them a reality without hiring anyone or spending 10,000 hours learning how to draw. Exercising their creativity might inspire them to learn the basics of art, to become better at using the AI.
I think you will see a drop-off in low effort content that is spat out instantly by AI, whether that's images, videos, or symphonies. In a sea of AI-generated content, the best or most interesting (viral) will rise to the top, and that will tend to favor the things that had some effort put into them. You might not even realize that AI was part of the process. If you listen to a symphony or other music created partially/fully by AI and you enjoy it, what then? Is it "bad" once you know AI was involved?
