I'm not dropping emdashes -- though you can always tell mine by their two-hyphen form lol
I've also never used an AI detector, and probably never will.
In my experience:
1. The people who rely the most on AI writing don't like to admit it. I catch obvious AI hallucinations in my boss's "documentation," and he always insists it was his own human oversight, despite it being very obviously a mistake I've caught Claude (and importantly, no human coworker) making repeatedly
2. I don't trust a machine more than myself to judge writing
3. Obvious AI "tells" just make it clear i don't need to keep reading, not that i need some kind of validation. In some sense, i guess that might save me time? But i still have to have read enough to know what it is...
In general, i think the author makes great points about how _LLM "thinking" is just the reproduction of the language of reasoning_, that is not necessarily a replacement for actual reasoning. It'll take a lot more than that for me to believe an AI is "thinking" and not just giving statistically reasonable answers (reasonable or actionable though they may be)
