I actually associate it with a younger writer, perhaps it skipped a generation. I can imagine that someone who grew up in a world where typing an em dash meant looking up an alt code would develop a style that avoids them—but it's only a long press of the - away on the device where I do most of my writing by volume so of course
I'm going to use them.
I just use commas or semi-colons where I would have previously used em dashes. It's annoying to have to adapt to avoid triggering people's faulty AI slop pattern matching, but the alternatives are perfectly fine.
