I just fundamentally disagree with this. On one hand, sure, you can argue that there is no direct harm caused by using LLMs to generate fiction for personal consumption. But on the other hand, I feel like there is a deep spiritual deadening that arises when we no longer must engage with the works of others to find fiction that satisfies our tastes. You have niche interests? What you want to read doesn't exist in a meaningful quantity or even at all? Great! You should write it! But you should do so yourself rather than asking a computer to regress your great idea to the mean.
