Dont forget there is also lots of thinking involved. Artists understand their context and work with that. Like they do things to piss people of or to contradict something. They are also painfuly aware of the fact that work cannt be too novel to become popular. Often times they “train” their audience to come to work they’ve done years ago. Artists are not only repeaters of image patterns like current AI is.

So unless the AI becomes concious then i dont think they will replicate this process. On they other hand they will be probably able to “brute force” novelty with mashing random things and help of humans to sort it out.
