>They've been doing some of these patterns for a while in certain places.
This exactly. LLMs learned these patterns from somewhere, but they didn't learn them from normal people having casual discussions on sites like Reddit or HN or from regular people's blog posts. So while there is a place where LLM-generated output might fit in, it doesn't in most places where it is being published.
Yeah, even when humans write in this artificial, punched-to-the-max, mic-drop style (as I've seen it described), there's a time and a place.
LLMs default to this style whether it makes sense or not. I don't write like this when chatting with my friends, even when I send them a long message, yet LLMs always default to this style, unless you tell them otherwise.
I think that's the tell. Always this style, always to the max, all the time.
