I have used a dash - like that for almost 20 years, 100% of the time I ought to use a semi-colon and about half of the time for commas - it let's me just keep talking about things, the comma is harder pause. I've recently started seriously writing at a literary level, and I have fallen in love with the em dash - it has a fantastic function within established professional writing, where it is used often - its why the AI uses it so much.
