You see it obviously with the artists and image/video generators too.
We did this with Dadaism and Impressionism and photography before this too with art.
Ultimately, it's just more abstraction that we have to get used to -- art is stuff people create with their human expression.
It is funny to see everyone argue so vehemently without any interest in the same arguments that happened in the past.
Exit through the giftshop is a good movie that explores that topic too, though with near-plagiarized mass production, not LLMs, but I guess that's pretty similar too!
