Seriously though, the thought of an llm running on a server interacting with my files is one of the most frightening things I can imagine happening to anyone

Do you lack imagination or are you mentally challenged?

How about being thrown into a pit of tarantulas?

Being thrown off a building?

Being tied down over a growing bamboo?

Having to face a polar bear with your beat hands?

Or are you files full of incantations that summons Cthulhu or demons or your worst fears and the llm interacting with it summons it?

Have you seen some of the black mirror episodes? There are much more frightening things in there.
