That's separating a clause from the sentence, used so that one might place a comma within the clause, as taught to me in year 5 or 6 english. One can use it regardless of commas as well.
Later on in high school, we learned that em dashes were reserved for special use cases in academic or technical papers, eg. I wouldn't use an em dash on reddit except maybe in a quote.
Where did I say 'this wasn't written by ai'? Have I challenged that anywhere?
I said 'hey, humans have been taught to write like that too'. Because... how do you think the bot learned it?
Is there anything else you'd like to attack me with?
Edit : Queensland Department of Education taught me that. It's not a US dept of 'ed'. Our education departments are there to guarantee a standard of education.

Em and en dashes are proper English if you know how to use them which it would seem you do not.
Don't give up your day job of teaching American to English Ai bots.
