I've loved em dashes for decades, so it's a shame they've become markers of AI writing. Perhaps AI picked up on them because they're such effective punctuation—much like the semicolon that Cecelia Watson defends in a NYT essay (https://www.nytimes.com/2021/02/09/magazine/the-case-for-semicolons.html). The em dash is so versatile that it's even infiltrated Spanish (the other language I habitually write in), where formal rules technically forbid the single dash.

Your point about moving beyond AI detection hits the mark. Good writing teachers could transform this moment of anxiety into opportunity. Imagine asking students to rewrite their handwritten work to sound like it came from a non-frontier AI model. What changes did they make? Why does AI write that way? Or flip it: take a piece written by a basic AI model and elevate it. What improvements did you make, and why?

Em dashes have long been the tool of masterful writers. Consider this 75-word microfiction piece and how skillfully it deploys em dashes to create rhythm and meaning in such a compressed space: https://www.smokelong.com/stories/thirteen/. That's the kind of intentional punctuation use we should be teaching—and celebrating.
