Just for the record, I’m not going to stop using em dashes just because LLMs use them too. But to prove my authenticity, I’ll occasionally use ’em dashes incorrectly - like this. Hopefully this is enough evidence of my human—typed—this bona fides.
More proof that a human typed this: miss-spellings, mixing of tenses, and the fact that I used “proved” in two consecutive sentence in an earlier revision (not to mention using it again in this reply).
