I don't pay attention to em dashes, they're overused as a pithy saying for sure

One problem with any shibboleths people are looking for is as people see more AI writing they're more likely to begin to pick up AI phrasing. I mean, if the power of Web apps can revive the past participle "gotten" in the UK, it shouldn't be surprising it can get people to use the verb "delve" more often.

The shibboleths aren’t the problem with AI writing; the problem is that it’s bad writing.

Good writing uses novel combinations of tools (vocabulary, rhetoric, metaphor) to communicate novel ideas. Bad writing is a cargo cult of those tools.
