Which Sci-Fi Story?
Summary: Only the human species master fiction...
Premise: short science fiction story from the 50s - only humans write fiction, and they are sought for this reason by all in the galaxy. Fiction is exported to everyone, all of it, however, prompt written by AI's - ranging from the very cheap to very expensive models, creating a variety of bad to sometimes good fiction - but these machines can also be tinkered with to make them better.
Spoiler: One very poor author breaks into a very successful colleague's house in the hope of stealing his AI-settings - but discovers that this person's AI is broken and that the successful stories are all written by hand.
Please: Which title, author and year? I think you'll have better luck at https://old.reddit.com/r/scifi/ with "ID this story" in the title. Have a vague memory of such a story, sounds like something Bradbury would have written. Galaxy Quest?!
