It used to be a big thing in the nineties: I've got old .asm source code of mine where I used to do that.

But somehow LLMs love to insert dashes everywhere: dashes in source code an em-dashes in prose. Just why?

Did they parse lots of early code and thought it was cool to insert, in modern programming languages, comment lines full of dashes?

Oh yes, all the time. And besides the fact that there are the off-by-ones errors, it of course looks horrible in Claude Code CLI seen that what you see is not what the LLM did output (because they vibe-coded their "real time game engine" that changes characters, for no reason, on the fly).

It's 2026 and we've got "intelligent" machines doing this:
