No, I think what he said was true. Human brains have something about them that allow for the invention of poetry or music. It wasn't something learned through prior experience and observation because there aren't any poems in the wild. You might argue there's something akin to music, but human music goes far beyond anything in nature.
We have an intrinsic (and strange) reward system for creating new things, and it's totally awesome. LLMs only started to become somewhat useful once researchers tried to tap in to that innate reward system and create proxies for it. We definitely have not succeeded in creating a perfect mimicry of that system though, as any alignment researcher would no doubt tell you.
