I had no idea what I was using were called “EM-dashes” until the AI bubble. I just used them to reflect pauses in my speech for tangents - an old habit from my IRC days.

Incidentally, some folks reported my stuff for potential AI generation and I had to respond to the mods about it. So that was kinda funny, if also sad to hear that some folks thought I was a bot.

I’m a dinosaur, not a robot dinosaur. I’m nowhere near that cool, alas.

But the em-dash is a different character. I think even those that use a pause would just opt for - on their keyboard, whereas the em-dash — requires additional work on most (all?) keyboard layouts. It's _not_ more work for an AI though hence why it's a tell.

The tell here is that you used a hyphen, not an em-dash.

  • Okay, see, that's context even I forget, but you're right and bears repeating:

    This `-` is a hyphen, which I love, even if I'm fairly sure I'm not using it correctly in grammar a lot of the time.

    This `--` is an EM-Dash, apparently, which is also what I never use but I also thought was just a hyphen in a different context (incorrect!).

    • No, there are actually four different punctuation marks, all which look remarkably similar to the untrained eye.

      1. We have the hyphen, which is most commonly used to create multi-part words, such as one-and-one-thousand.

      2. We have the EN-DASH, which is most commonly used to denote spans of ranges. As an example, Barack Obama was President 2009–2017.

      3. Then we have the recently maligned EM-DASH, which can be used in place of a variety of other punctuation marks, such as commas, colons, and parentheses. Very frequently, AI will use the em-dash as a way to separate two clauses and provide forward motion. AI uses it for the same reason that writers do: the em-dash is just a nicer punctuation mark compared to the colon.

      4. Lastly, we have the minus sign, which is slightly different than the hyphen, though on most keyboards they're combined into the hyphen-minus.

      By the by, they're called the em-dash and the en-dash because they match the length of an uppercase M or N, respectively.

    • It is probably even a hyphen-minus, so called because on most early keyboards one character had to do to represent both a hyphen and a minus. In Unicode, there is a separate code point for an unambiguous hyphen. There is also a non-breaking hyphen as well as the various dashes discussed here.

      And "--" is absolutely just two hyphen-minuses, not an em-dash (—).
