I add em dashes to everything I write now, solely to throw people who look for them off. Lots of editors add them automatically when you have two sequential dashes between words — a common occurrence, like that one. And this is is Chrome on iOS doing it automatically.
Ooh, I used “sequential”, ooh, I used an em dash. ZOMG AI IS COMING FOR US ALL
Always write what you want, however you want to write it. If some reader somewhere decides to be judgemental because of — you know — an em dash or an X/Y comparison or a complement or some other thing that they think pins you down as being a bot, then that's entirely their own problem. Not yours.
