There is no benefit to humanity, in aggregate, to have copyright remotely as it is today - as a legal hammer and as IP for corporate profits and all the rest.
I certainly think LLMs count as transformative usage in either case. And for something like the Ghibli meme, let's mourn the loss of our ability to distinguish real Ghibli art made with human intention from AI slop, but I'm not going to feel too bad that something that used to be laborious to create is suddenly trivial.
AI is a tool: Miyazaki could produce films at 10x speed with exactly the same care and quality. This exactly mirrors the complaints people had when the printing press came around and suddenly scribes had no value and laboriously and meticulously created books were now printed on trashy paper that cost 1/100th the price. And we did lose something in that, but what we gained was immeasurably more important.
