> I wrote this comment the same way. The LLM fixed 14 grammar mistakes that I think would distract readers more than any LLM-ish phrasing.

I don't think that assumption is correct. As you can see by the discussion we're having here, the LLM "fixed" text is actually quite distracting, while text written by a reasonably proficient non-native speaker is generally perfectly readable. It's only if your English is extremely poor to non-existant that it makes more sense to use machine translation or editing rather than writing it yourself.

One problem is that people are becoming quite sensitive to slop, where people just post completely unreviewed, AI generated text. It's quite frustrating, because it's asking readers to read something that no one has ever bothered to write, and it frequently crowds out discussion that people are more interested in. So everyone is kind of hyper-sensitive to signs of AI written text right now, which means when you start to see such signs, your brain moves over to trying to interpret whether it's AI generated rather than reading the text itself.
