This is how you people sound.
You can't recognize AI. Nobody can without training specifically to recognize AI, and eve then, it's only been shown to be successful with a language with an online corpus significantly smaller than English.
The thing LLMs are best at in the entire world is imitating human writing. So all you're really doing is discouraging a human from writing.
I hate AI in the artistic disciplines. No one hates it more than I do. But Jesus Christ, I've been seeing legitimate authors get called AI for over a year now, and it's so bad that I know people are quitting writing over it. ("What's the point, everyone stopped reading because they think I'm AI") End result being the percentage of writing that is AI goes up, and humans enjoying the most human of all disciplines goes down.
