Fact is that I maybe saw it in 10% of blogs and news articles before Chatgpt. And now it pops up in emails, slack messages, HN/reddit comments and probably more than half of blog posts?

Yes it's not a guarantee but it is at least a very good signal that something was at least partially LLM written. It is also a very practical signal, there are a few other signs but none of them are this obvious.

I believe you. But also be aware of the Frequency Illusion. The fact that someone mentions that as an LLM signal also makes you see it more.

Which is perfectly congruent with what I said with emphasis:

> it is never sufficient on its own to identify LLM use

I have no quarrel with using it as one signal. My beef is when it’s used as the principal or sole signal.

Dubious. The only signal this gives that in aggregate people use AI. On individual basis, presence of em dashes means nothing.

Yeah, maybe that's the one thing people who didn't know how to do it before have learnt from "AI" output.
