This is a summary from ChatGPT. Source summarized: With the Em Dash, A.I. Embraces a Fading Tradition

AI’s persistent use of the em dash has triggered a minor cultural freakout online, with many insisting it’s a “tell” that instantly reveals machine-generated text. Yet the dash is a centuries-old punctuation mark beloved by novelists and grammarians, and its sudden suspicion says more about modern typing habits than any deep AI quirk.

• AI writing often features em dashes without spaces, a style lifted from traditional print typography.
• Humans increasingly avoid the em dash in casual digital communication, favoring spaced-out hyphens or en dashes out of convenience.
• Online forums branded the em dash a “GPT-ism”, claiming its presence makes writing feel robotic.
• Historical usage proves the opposite—Dickens, Dickinson, and Salinger all leaned heavily on dashes for rhythm and voice.
• The real AI giveaway is orthography, not punctuation choice—spacing and keystroke habits matter more than the mark itself.
• Modern text-focused communication is flattening our punctuation palette, as speech moves to typed forms.
• AI exposes the gap between literary tradition and digital convenience, unintentionally reviving the em dash’s reputation.

The piece opens with the internet’s recent obsession with spotting AI through punctuation, particularly the em dash. ChatGPT’s habit of slinging pristine, unspaced em dashes provoked an online chorus: “No human writes like that.” Tech forums, Reddit threads, and OpenAI’s own community spun tales of the em dash as a dead giveaway—poisoning otherwise human-sounding copy for customer service, writing prompts, and casual notes. Ironically, this consensus ignored that the em dash has been in steady literary use for centuries. Its supposed “robotic” quality is a mirage of digital culture, not linguistics.

The author reflects on their own life as a dash enthusiast and former proofreader, noting how punctuation mirrors thought. Em dashes let sentences breathe like conversation, opening room for interruptions, shifts, and the unpolished complexity of human thinking. From J.D. Salinger’s jittery dialogue to Stephen King’s narrative sprawl, dashes are a bridge between the written and the spoken. What many internet users are actually rejecting isn’t the dash itself—it’s ChatGPT’s formal print styling, which rarely appears in texting, tweeting, or online comments. The typographic neatness, not the punctuation mark, is what reads as “AI.”

As the debate swirled, it revealed a broader cultural shift: digital communication habits are far narrower than literary tradition. Most users type hyphens, rely on autocorrect for en dashes, and sprinkle spaces where none technically belong. The em dash’s fall from common usage isn’t about necessity but friction—few know how to summon it, and most software encourages more primitive marks. In that context, AI’s em-dash enthusiasm feels both archaic and charmingly bookish, a throwback to a time when punctuation aimed to capture the rhythms of thought rather than the constraints of a chat window.
