Em-dashes earn trust
Punctuation often comes under assault. Kurt Vonnegut in 2005: “Here is a lesson in creative writing. First rule: Do not use semicolons. They are transvestite hermaphrodites representing absolutely nothing. All they do is show you’ve been to college.” Recently, there's been a wave of em-dash hate. Since chatbots tend to aggressively use them (multiple times per paragraph), any writer who includes them is now accused for having AI write for them. But I trust your writing less if you don’t use em-dashes.
First, it shows you’re not fluent enough in basic punctuation to properly articulate the thoughts in your own mind. I mean, sure, you get a lot done with just periods and commas, but punctuation marks are like visual aids that give you more precision in what ideas mean and how they are connected. I see em-dashes and parenthesis as siblings (of inverse function) that work together to help give structure to your emergent thoughts. I often find myself—mid-sentence—wanting to add details and embellishments; if they don’t fit into the structure of that sentence, I can contain them with punctuation. Both the ( ) and the "—[ ]—" let you inject detail into a sentence. They are “innies.” They either clarify or complexify.
These innie remarks are often a meta layer where the writer is reflecting on how the reader is processing their sentence, and they add clarification to make sure they are understood. They are punctuation marks about self-consciousness. Losing them is like losing a whole dimension of self-reflection. They’re used for digression, tension, clarification. Without them, you're not letting me see your mind at work, you are merelyh communicating. I wonder if AI bakes them in (via system prompt?) to give the illusion of a mind in thought, yet it’s really just capturing the syntax, and not really using it for digressions.
