Edit: To be more clear, I mean the implication (no matter how qualified) that it is remarkable to even ask a question based on how likely it is that experts have already answered the question. That premise doesn't seem to make any sense: First, non-experts have no context for knowing what experts have likely ruled out and what they haven't, by definition. Second, if experts have ruled it out, the answer to the question is still valuable (how/why did they rule it out).
