I feel the same way. I've used em-dashes in my writing forever, and I was always particular about making sure they were used properly (from a typography standpoint with no surrounding spaces).

But now, I have to be so picky about when I use them, even when I think it's the perfect punctuation mark. I'll often just resort to a single hyphen with spaces around. It's wrong, but it doesn't signal someone to go "AI AI AI!!"

Dont worry, soon LLMs will be trained to avoid using em dashes and then all will be right in your world again!
