Your comment has a hyphen not an em dash. The point of the post is that AI likes to include em dashes, which are wildly uncommon in modern text, as most keyboards don't have a key for it
They’re pretty trivial to make in any OS — having a dedicated key isn’t necessary.
but most people, outside of professional writers and linguists, don't use them
Odd, I see them used all the time, and I’m neither. So I guess either my experience is an outlier, everyone I talk to is secretly an LLM, or maybe the meme is pushing an easy conclusion because people in general are bad at picking up on LLM responses and want an easy punctuation mark so they don’t have to think.
Weird, i hardly ever see a normal hyphen, let alone an em dash, but of course it's not a foolproof method to detect ai, just a strong indicator
Sure. Most people don't know what an OS is, let alone how to enter special characters.
I think this is something macOS does best — using shift+option hyphen is a bit quicker than alt+0151.
Long pressing the hyphen on the Google keyboard on Android also gives the option of selecting an en dash or em dash.
On Linux, if you have the compose key enabled, Compose key + three hyphens in a row will generate an em dash (en dash is two hyphens).
…well I’m definitely turning that on for my Linux machine then. Thanks for the tip.
It's convenient for a lot of things. Curly quotes, specialized dashes, mathematical symbols or Greek letters used in math/science, foreign currencies, things like paragraph symbols (¶) or section symbols (§), etc.
