AI might suck, but if the author doesn't change, they get categorized as a lazy AI user, unless the rest of their writing is so spectacular that it's obvious an AI didn't write it.
My personal situation is fine though. AI writing usually has better sentence structure, so it's pretty easy (to me at least) to distinguish my own writing from AI because I have run-on sentences and too many commas. Nobody will ever confuse me with a lazy AI user, I'm just plain bad at writing.
There's your trouble. The real problem is that most internet users are setting their baseline for "standard issue human writing" at exactly the level they themselves write. The problem is that more and more people do not draw a line between casual/professional writing, and as such balk at very normal professional writing as potentially AI-driven.
Blame OS developers for making it easy—SO easy!—to add all manner of special characters while typing if you wish, but the use of those characters, once they were within easy reach, grew well before AI writing became a widespread thing. If it hadn't, would AI be using it so much now?
I also tend to way overuse parenthesis (because I tend to wander in the middle of sentences) but they haven't shown up much in llms so /shrug.
No, you are writing for people who see LLM-signals and read on anyway.
Not sure that that's a win for you.
