@plexus I remember reading a good post (I think by @mekkaokereke ) about how language is used by groups to protect against people trying to infiltrate them without a shared background.

It wouldn't surprise me if the same thing happened to defend against LLMs - you won't accept, say, a job application if there aren't at least a couple of uses of 0-day slang or memes. Language evolves fast, it's one of the amazing things about it.
