Yep, I was right back on page 3. 5 pages of this topic with people saying the same things over and over and over again along with some totally unrelated conversation on the side.
Yes, experts exist. An expert is simply someone who has achieved excellence and has a thorough knowledge of a subject. This common line that no one is an expert because nobody knows it all is faulty logic. I know who the experts are at my field. I have about half a dozen guys that I'll ask questions of, and generally I know who knows what because I know their experience. I don't expect them to know absolutely everything, but they do a lot and (even more impressively) they know what they don't know. Guys like that bring a lot of value to the groups they are a part of and deserve our respect.
