My hardware prof said "bad data is worse than no data, because it deceives us".
This is where I am with LLMs; why I still don't use em (outside of research). I can believe that the fourth beast is no worse than most of you lot. But I was already struggling to process you.
(Obviously there's lots of places where semi-fictitious data is fine, like idea generation, art, idle talk, and what we called "spraffing": the conversational annealing that comes to you when you lie horizontal on grass and just talk without logical or artistic intent)
