Google Gemini has literally no idea how it is being used. It made that up.
But presumably the LLMs do have some knowledge about how they are used?
On further probing Gemini did give a plausible justification - in summary:
"Creation is easy. Selection is hard. In an era of infinite content, the "most successful" writer isn't the one who can produce the most; it's the one with the best taste. Using an LLM as a distillation machine allows a writer to iterate through their own ideas at 10x speed, discarding the "average" and keeping only the "potent."
Leave it to the reader to decide how informative that would be.
