I may take some flak for saying this, but I don't think you did anything wrong. You stated up front that it was AI generated. You didn't claim as a work of anything but. And you presented it as an example.

I also get why people are mad about AI generated stories. And I'm in the same camp as them. But I also know that AI is not going to go away and it's only going to get smarter. And we're going to have to figure out how to live with it.
