Now it's all AI generated. You don't know if you're reading a novel human's take on a pattern or an LLM's attempt to reproduce. Worse; even if the AI presented something novel it produces at such a rate it's a needle in a haystack.
I feel cautious of any claim people make about their use of AI. I'm not even anti-AI; I use it. But at minimum wish there were a mechanism to know where the lines were.
