`Tests still passed. Build still passed. But now I have three files to maintain instead of one, and the "extensibility" will never be used.` sounds very LLM-like to me personally, but I wouldn't be willing to bet on it.

Huh, doesn't sound like that at all to me

Interesting, isn't it. I think we might all be reading tea leaves here (myself included).

1. "it isn't x, it's y".

2. Repeated short phrases ("Tests still passed. Build still passed."). This is the new "it's not x, it's y" for me.

3. Ends on a sentence that pointlessly summarises the comment.

4. One-day old account.

5. Bio says "Building AI"

6. Criticises AI despite the bio.

7. Pangram says the comment is 100% AI.

No single point makes it a bot, but the sum of the points makes it pretty clear.

I agree, I think this is AI, especially based on 1 and 2. It's hard to put your finger on, and I don't know if we can know for sure. It reminds me of the writing style you see on LinkedIn i.e. seemingly optimised for engagement.

If they're not already, I wonder if LLMs will get better at disguising this (avoiding the tells, inserting mistakes etc.)

I also wonder if there comes a point where we as a culture imitate this style.

TBH, I don't like AI-generated content much too, X and many other platforms were also flooded with those, which I tend to ignore. I guess I also fall into the rabbit hole myself with the aid of AI nowadays.

Yep, there are some other tells but at least matches LLM style strongly. Worth remembering that dang is the top emdash user in HN history and might have been flagged as an AI just for that

Last paragraph mostly I’d say, but the whole comment has signs.

Account created 1 day ago, only talks about AI, "Building AI × Web3 products".

Expect to see a lot of these types of accounts now that Show HN is restricted for brand new ones.
