Kind of beating a dead horse here -- the debate has never been about whether AI should be embraced by the forum; that doesn't matter, people can use it all day long for all I care. The real debate is whether it should be permissible to post AI-generated content and pretend its your own.
In other words, you don't believe it because you have an immovable preconception that you won't let reality change.
Obviously a lot of ChatGPT/Grok/whatever output follows a very recognizable format or "style". Everyone else might not mind it as much as me but there's no way I'm going to entertain the idea of talking with a bot while thinking I'm talking with an actual human. Maybe in the future it will become a bit more refined but for now its pretty easy to tell when someone is trying to pass off AI as their own words, and to be honest its a bit insulting.
