I don't have a great writing style -- it's too verbose and often has run-on sentences that seemingly never end.

And I do use the en-dash / em-dash a lot -- probably incorrectly.

All flaws aside, it would be very unfair of anyone -- much less any purported expert in AI -- to suggest that frequent usage of this punctuation -- irrespective of whether it is tasteful or not -- is a sign of AI generated text (or slop).
