On the one hand, I think that most people are way too snobby — they think that most people (except those like themselves) are idiots. (Why, I don’t know. I can’t see it from where I’m standing.)
But there are some cases where the distance between the superstars and everyone else is huge. Night and day. My first job out of college was at Activision, back in its glory days in the Eighties. I learned that there were two kinds of video game designers: the ones who could write games that were fun, and the ones who couldn’t. There was no known technique of turning someone who wrote boring games into one who wrote interesting ones.
