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!
Been using shift+option+hyphen to make and use em-dashes (sans spaces) since at least 2005, when I got my first publishing job and also started blogging (so writing a ton more). I also use option+hyphen (en-dash) for date and number ranges. In my experience, ChatGPT consistently adds spaces around both.
