There's more quality fiction out there than you or I will ever have time to read. I don't see a purpose in flooding the world with more mediocre to unreadable fiction.

I am not going to argue this on the basis of LLM's suck at fiction, because even if it's true, it's not really that relevant. The problem is that what LLM's are good at is producing mediocre fiction particular to the tastes of the individual reading at. What people will keep reading is fiction that an LLM is writing because they personally asked it to write it.

I don't want to read fiction generated from someone else's ideas. I want to read LLM fiction generated from my weird quirks and personal taste.
