they put spaces there so their AI generated text looks a bit more human, when in reality humans rarely use em dashes for casual comments or text. The only use for it prior to AI cuntwriting was in high brow literature, philosophy and wannabe high brow internet writing. But ai thinks that just how we talk

Before the LLMs made the emdash the tool of the electronic oppressor I used it often enough and other people did too.

I hate that it's basically become the little hitler moustache of punctuation. There was at least one guy who was really enjoying his tiny little moustache until he couldn't anymore. That is the emdash for me.
