LLM-isms are tolerably bad. LLM's narrative ability is intolerably terrible. As others said, because a human actually wrote the overall narration for this, it was still compelling to read. The mistake would be skipping a well-narrated and thoughtful article just because of a few bad LLMisms.

I think LLM's lack of "theory of mind" leads to them severely underperforming on narration and humor.
