OK, but please don't do what pg did a year or so ago and dismiss anyone who wrote "delve" as AI writing. I've been using "delve" in speech for 15+ years. It's just a question where and how one learns their English.
That's what makes it such a good giveaway. I'm happy to be told that I'm wrong, and that you do actually use the proper double long dash in your writing, but I'm guessing that you actually use the human slang for an emdash, which is visually different and easily sets your writing apart as not AI writing!
On Linux, I use Compose-hyphen-hyphen-hyphen.
I don't use it as often as I used to; but when I was younger, I was enough of a nerd to use it in my writing all the time. And yes, always careful to use it correctly, and not confuse it with an en-dash. Also used to write out proper balanced curly quotes on macOS, before it was done automatically in many places.
