If yiu have any real examples of llm written text that's as fun to read as that, I'd be curious to see them. Most llm text I see is vapid and uninspired. Kinda exactly the mediocre writing you'd expect from a machine designed to create statistically average sentences based on all the writing its creators could steal.
LLMs write bland LinkedIn "thinkpieces", not Douglas Adams style creative wordplay.
I don't believe anybody should care. If AI made it better, why should I care that they used AI? Either way, I doubt this was AI-assisted - I absolutely love this style.
