That jovial overly friendly tone is a give away. Like to thinks its writing style is HILARIOUSLY clever

the reason LLMs use that jovial, overly friendly tone is because it's so common in journalism and marketing. this article does smell of ChatGPT, but there's absolutely no way to know for sure. people using LLMs annoy me just as much as people who are so certain that they can tell the difference

a smart person can make ChatGPT sounds completely authentic, and a very boring and middle of the road writer who uses em-dashes can make themselves sound completely inauthentic. it's not like LLMs got their style from nowhere

as far as I'm concerned, as long as the factual information has been curated by a human, I don't give a shit
