Because I find LLM-generated content very annoying to read. It's sloggish, bloated, and the speaker always has this cringe way of trying to connect to the audience.

I don't believe the story itself is made up by an LLM but I'd argue that if you have an LLM write your story then it's no problem for you to have it add a TL;DR at the top so we can skip the slop.
