I can not stand that I'm expected to adjust my use of em-dashes because LLMs use them (incorrectly, typically). It brings up all these feelings from my younger punk / indie days when normies would get into a band we were into, and then we were expected to not like that band anymore. Since then I've tried to abide by what I call the Farting Billion Principle. People shouldn't have to change their ways everytime a billionaire farts.
