Anyway, that's the kind of world I'd like to live in. Everyone can (and should) be an artist to some degree. While I do agree with the fairly obvious point that some people are more talented than others, I reject the idea that there are "genius artists", spikes of talent on an otherwise smooth talent-graph.
Keep imagining. But great ones aren't. Go read:

EDIT to add: Why Jobs stood out is because the closest equivalent to what he was is a film director. But business is not set up to hand out accolades like Hollywood does. So instead of everyone learning who did what in Apple -- as with film we find out about sound editors, foley artists, etc, etc. -- we just get the face of Jobs.
