I included it to explain the idea of complementarity. It also has some sentimental value, I guess, because long ago I learned that idea from that article.

The larger point I wanted to make: success requires more than just being good at your specialized skill. Well, if someone's good enough to build a new platform, create a killer app for it, and bring it all to market, then more power to that person! The rest of us need to be conscious about what other skillsets are required to make our own skillset useful to anybody. Good examples to keep in mind are Apple II + Visicalc and Xbox + Halo.
