I would make the claim this paper shows the weakness of AI generated text. People are comfortable with familiar things. We know AI is sampling probability distributions in a latent space and by definition don't sample outside of them. Human poetry is creating net new things. Net new ideas which aren't just rehashes of past ideas. And this can definitely be uncomfortable for people, especially the layman.

In other words, general public is afraid of Jazz, they like pop music. But Jazz is where the new stuff is. AI is creating pop music, not Jazz.
