I can't believe we're going to forever have to live with people who don't speak English as a first language having their written work assumed to be done by AI. It's pretty disappointing.
I was recently linked a list of 1,000+ words that "shouldn't be used" because they're "evidence" of AI. Oh, and if you use bullet points, obviously AI. Dashes? AI. Paragraphs with opening and concluding sentences? AI!
Not that inserting an aside about a different language is bad writing. It's also weird enough that it's exactly what I would not expect an AI to do (except perhaps under very odd and specific circumstances). "It's clearly AI" has become a catchall for any writing that people find even mildly bad or surprising.
