alt Hacker News>Excuse me, what do you mean there? The author happens to read HN too.
Read the rest of the comment. It's not suspect because it's referencing HN, it's suspect because of the way it's referencing HN. Specifically, its use of the phrase "the HN thread", even though it wasn't mentioned before. Maybe it's a editing gaff, but it's also consistent with how an LLM would write if presented with a list of sources.
Yep, this feels like a smoking gun. The others are circumstantial, maybe indicative, maybe not. While there’s a chance this is an editing gaff, its overwhelmingly likely to be LLM, ahem, “cruft”.
