I’m not going crazy, right, nearly nobody aside from professional writers used em dashes prior to 2022. And the whole bolded topic intro, colon, short 1-2 sentence explanation seems way more like a product of GPT formatting than how organic humans would structure it?

So much writing on the internet seems derivative nowadays (because it is, thanks to AI). I’d rather not read it though, it’s boring and feels like a samey waste of time. I do question how much of this is a feedback loop from people reading LLM text all the time, and subconsciously copying the structure and formatting in their own writing, but that’s probably way too optimistic.
