For me it's not really the length, I'm surprised that on HN news of all places you'd think it's that. Outside of the obvious em-dashes (yes I know people have always used em-dashes but one every other sentence does catch the eye right?), it's the common and completely self-assured phrasing like

"which is why you get that "barrage of micro ideas" breaking through during focus."

This for me was the biggest tell. Unless OP gives their credentials who talks like this? The smartest people I know in related fields go out of their way to avoid sounding like they can diagnose your exact subjective experience based on such little information. The absolute lack of reasonable hedging is the giveaway for me.
