Isn't the first em dash taken from an interview that the writer did with the subject over Zoom? I think using an em dash to punctuate a broken or partial sentence like that is pretty standard journalistic practice when you don't want to modify the original quotation (e.g, denote a paraphrase with brackets), and definitely not an AI tell.

The other uses are honestly pretty standard rhetorical patterns; they do not seem especially AI-flavored to me.
