The Em Dash You Never Typed — and What It Says About Machine Design

There’s a tiny piece of punctuation that says a lot about how technology shapes human behavior — the em dash (—).

You see it everywhere: in crisp copy, polished articles, and AI-written blogs. It feels smooth, professional, intentional. But here’s the thing — you probably didn’t type it. Not because you forgot, but because your keyboard never gave you a way to.

The Missing Key

There are three dashes in English:

• Hyphen (-) – short and simple.
• En dash (–) – used for ranges (2020–2025).
• Em dash (—) – the long, elegant one — like this.

In traditional printing, each dash was literally the width of a particular letter:

• The hyphen matched the narrowest stroke.
• The en dash was the width of a capital “N.”
• The em dash — the widest — was the width of a capital “M.”

So “em” and “en” aren’t fancy prefixes — they’re measurements from the physical world of metal type. The language of the printing press still lingers in our digital punctuation.

The em dash is a favorite among writers because it mirrors how we think — fast, conversational, full of pauses. But on a standard keyboard, it doesn’t exist. You’d need a secret shortcut:

• Mac: Shift + Option + Hyphen
• Windows: Alt + 0151

Most of us don’t bother. We type two hyphens, or skip it entirely. The system quietly shapes our habits.

Enter the Machines

AI tools don’t have that problem. They don’t type — they generate. Which means they can use em dashes and en dashes flawlessly, every time.

That’s why so much AI-written content looks oddly “perfect.” It’s formatted exactly how the rulebooks say it should be — because AI isn’t limited by design, keyboards, or human shortcuts.

In other words: machines write beyond our tools.

The Bigger Picture

That tiny typographic quirk is a perfect metaphor for digital transformation itself. Every time we simplify a process — whether it’s a keyboard layout or an automated workflow — we gain speed, but lose nuance.

What humans can’t easily type, we stop thinking to use. What machines can do effortlessly, they start to overuse.

And somewhere between the two lies authenticity — the small imperfection that reminds readers a person was here.

Why It Matters

Transformation isn’t just about upgrading technology — it’s about designing systems that still let people sound and feel human.

Because yes, AI can use the em dash perfectly. But sometimes, imperfection is what makes communication real.

If you guessed who wrote this — human or AI — based on the em dashes alone, you might just be part machine yourself.
