You're not being charitable with the take. seems like you just switched "objective truth" with your flavor: "error rate"

what is an error? how does the llm "know"?

wikipedia example is good. i'd say its "truth" is based on human curated consensus. everyone gets that. what i don't get what's the llm analog? as you state, it's just about making the error rate go down, ok so what is an error? does it require human in the loop?
