This doesn't follow. For instance, there are some pictures that I know are AI-generated, yet they're still beautiful to me. Nothing jaw-dropping, just very nice. Being AI-generated doesn't automatically mean being not worthy, especially when it comes to art. I understand, this is kind of insulting to human artists, writers, etc: we thought only the human soul and Nature could produce "the beautiful", but apparently not.
Which is not surprising, because LLMs are specifically trained to please their audience. Of course they can produce uhhhh "content" that people will find beautiful, that's not even necessarily a "bad" thing.
