Like, I can ask a friend and they'll mistakenly make up a reference. "Yeah, didn't so-and-so write a paper on that? Oh they didn't? Oh never mind, I must have been thinking of something else." Does that mean I should never ask my friend about anything ever again?
Nobody should be using these as sources of infallible truth. That's a bonkers attitude. We should be using them as insanely knowledgeable tutors who are sometimes wrong. Ask and then verify.
The net benefit is huge.
