I learned all I needed to know about AI when I turned to it to confirm a claim I had made on this forum. I found exactly what I was looking for and was getting ready to post it here as confirmation. Then on closer inspection I discovered that the source for this "confirmation" was the post I had made on this very forum. I'm glad I caught it before I posted it. That could have been really embarrassing.
I do find that AI is useful in completing sentences for me although I have to check to make sure it has filled in what I had intended. Once in a while, it actually makes the point better than I would have.
I suppose there are probably AI apps that could actually write a coherent post arguing for a point of view or refuting somebody else's. I wonder what it would do with some of MTG's posts.
