The AI wildfire is coming. it's going to be painful and healthy

> it's not X (emdash) it's Y

No, no, no! Stop that! The em dash is an wonderful little punctuation mark that's damned useful when used with purpose. You can't turn it into some scarlet glyph just because normal people finally noticed they exist. LLMs use them because we used them, damn it.

For god's sake, are we supposed to go back to the dark ages of the double hyphen like typographic barbarians in the hopes that a future update won't ruin that, too? After all the work to get text editors to automatically substitute them in the first place?

What's funny is that, when people first started noticing that LLMs tended to like the em dash, I'd mentioned to a friend that I hoped—rather naively—it might lead to a resurgence and people would think to themselves "huh, that looks pretty useful." Needless to say, I got that one wrong. Are we really going to sacrifice the poor em dash just because people can't come up with a better signifier for LLM text?

Oh, no thanks. The emdash is lazy writing, through and through, for the same reason a parenthetical expressed any other way might be. LLMs overuse them the same way humans do: to pack in context where it doesn't belong. I'd happily lay the emdash and all its terrible cousins upon the sacrificial altar to see a renaissance in editing and proper sentence construction.

I first learned about em dash reading the GNU Texinfo manual in the 1990s. Now I have to wear a red, slightly long horizontal line on my shirt, and passersby shun me.

I’ve never seen an LLM use an em-dash the way a thoughtful human is most likely to use them, in a parentheses-like pair. It’s just too bad there’s way too many idiots who cannot notice such subtleties.
