> pg has the fortune or misfortune to write in a way that feels like some LLM writing, when he's writing well.

It pains me to think how simplistic some peoples' LLM writing detection heuristics are (or at least appear to be). Prose such as in TFA is really obviously human-written to me. It's using those choppy sentences properly. It doesn't strike me as "less well-written" at all; the resulting contrast is clearly very intentional.

Although, of course, what you describe is still a couple levels above "Behold, what doth mine Ctrl-F espy but U+2014 EM DASH! Hie thee hence, O wretched automaton!"
