Very. I dont just use em dashes but also tend to write in a way that gets mistaken for AI a bit too much for my liking. In the worst of cases, I have watched AI detection softwares flag my assignments as "high likelihood of being AI generated" despite me not even having used AI for them. Before Chatgpt was mainstream, professors thought that my writing sounded well versed, elonquent and professional, now I just get slapped with an accusation of using AI when I actually didnt.
