Speed is not the measure of creativity. I don't think anyone will deny that machines can do some things way faster than humans; this has little to do with AI in particular.

I don't think this "poem" matches or surpasses most humans trained in poetry.

I don't have to provide anything. I mean, there's a huge body of poetry (that this LLM was trained on, by the way) to compare it to. Pick poetry you like, and compare it to this one. You'll see the difference in quality.
