The emojis used in the bullet points (which are missing from your original text, but were added in at some point) are also dead giveaways that AI was involved here.
It is perfectly possible, and even easy, to write e[nm] dashes manually. With compose key sequences it's barely more effort than typing a normal dash/hyphen, even. (Just compose key + `-.` for en dash, and `--` for em dash.)
In Russia, we have many typography keyboards/addons, because, well, it historically looked very silly to use double-minus or "-quotes instead of «»-quotes.
I've no idea how some countries got their typography standardized on the PCs and have it from the very beginning (Germany with their quotes for example), but the other countries need to setup external software and configuration. Apparently, US also didn't got their "third level" keyboard as a standard.
Ignoring references, just in article text: 5800 words (spaces); 78 em dashes (1.3%); 0 en dashes; 90 hyphens (1.5%).
English version of same timeframe: 16000 words; 0 em dashes; 32 en dashes (0.2%); 262 hyphens (1.6%).
