My novice AI-art workflow involved a similar pattern. I come up with some topic or thing I want to see, then I iterate on the wording of the prompt and all the little variables the tool takes. I end up with dozens of crap pictures, but sometimes cool stuff comes out. If I keep working on this, alongside increased generation speed, I could see myself "creating" really good art.
To me it is about the process. It's the human input that makes art valuable. I mean, if AI becomes sentient then those judgements would be a valuable input in themselves too.
