Em dashes being associated with AI is a disservice to them; in many cases they’re a far more suitable use of punctuation in interrupting a sentence than parentheses.
In this instance, however, the em dashes between the first and second parts of sentences would be better replaced with semicolons than commas, in my opinion.
They’re definitely more likely to be used by AI than by the average person, but I think that’s in large part because people aren’t generally taught to use them, along with their absence from keyboards.
Since keyboards have two minus sign keys, I have a script running on my computer to automatically replace one of their inputs with an em dash.
