Thing is, I started appreciating this way of looking at art only after reading anti-LLM arguments, and I am a bit angry at myself for not feeling it during the pre-LLM decades of my life, which would have been much enriched.

There is this other way of looking at art (which probably dominated my worldview) where you don't care much about where it comes from. An extreme example is reading Harry Potter fanfiction, which in some way feels like reading math proofs, namely you continuously wonder what else can be done in a largely fixed setting.
