I don't know where the recent idea that em dashes are difficult to type came from. MS Word automates turning a hyphen into an em dash as you type in the same way that it converts "teh" into "the" and has done so for as long as I can remember.

I find the whole AI / em dash thing frustrating as I used to used them all the time. They have meaning that hyphens don't. I've now had to stop using them because they are seen as AI generated, and structure my sentences differently as a result.
