It's actually excellent at evaluating content, it really depends on which AI model you're using.
Don't underestimate it. What AI is not great at is being creative. I mean, you can give it in a prompt to play a new song or create a picture or write a story, but they won't be better than a skilled human can do. At least not yet. At some point, however, I fear we will all be superfluous.
BTW, I've had an AI refer me back to AK posts that I'd made and forgotten about as well... D'oh!
