I only disagree a little. It's that sometimes there is a discussion about AI itself where "I prompted X with Y and it output Z" can add to the convo.
But those are pretty specific cases (For example, discussing AI in healthcare). That's about the only time where I think it's reasonable to post the AI output so it can be analyzed/criticized.
What's not helpful is I've been hit by users who haven't disclosed that they are just using AI. It takes a few back and forths before I realize that they are just a bot which is annoying.
