The problem with AI writing isn’t the tics and the tells. The problem with AI writing is that it’s bad.
The typical highly voted HN AI-written post has an annoying clickbait title, then jumps into a meandering chain of “so there I was” scene-setting, assertions of dubious reliability & relevance, and supposed supporting examples. All punctuated by short, unhelpfully dramatic sentences that would interrupt the high-level narrative, if only there were one.
I’m really curious what “good AI writing” you had in mind. My personal intuition is that for almost any topic, the HN LLM-generated post du jour has a far superior cousin sitting in the archive pre-2021.
