alt Hacker NewsI've seen a fair number of cases where someone swears up and down not to be using AI to generate responses, but there's no good reason to believe it (except perhaps specifically for the messages where that claim is made).
This includes times that someone basically disappeared from e.g. Stack Overflow at some point before the release of ChatGPT, having written a bunch of posts that barely demonstrate functional literacy or comprehension of English; and then came back afterward posting long messages with impeccable grammar and spelling in textbook "LLM house style".
There are a ton of people like that, but the LLM house style also exists because a ton of people write that way too.
The people falsely accused because they've used em-dashes for 20 years aren't the ones that were functionally illiterate before.
