tiawd: “Of course, not every guy with smicha possesses that level of wisdom.”
That is a very important point. The word Rav is very widely-used nowadays and can refer to a very wide range of individuals. So what questions or type of questions a Rav is qualified to answer may depend on the Rav in question.
Some of the posters were making the claim that a Rav is not the best person to ask certain types of questions to. While that may be true, the extent to which it is true would depend on who your Rav is and therefore how much “Daas Torah” he possesses.
Your local Orthodox Rabbi is probably not the Gadol Hador, so there probably are questions that he wouldn’t be qualified to answer, but a Gadol Hador would be.
