Wednesday, January 16, 13What we’re really engaged in is building a platform for a global internet operating system. Back in 2002, I ran a conference entitled Buidlingthe Internet Operating System. In his keynote at that conference, Clay Shirky told a thought-provoking story. He remarked on the assertion byIBM CEO Thomas Watson Jr. that he saw no need for more than ﬁve computers in the world. “We now know that he was wrong,” said Clay. Theaudience nodded, thinking of the millions of PCs in the world. Today, it’s billions of smartphones. But then Clay delivered his devastatingpunch line: “We now know that he overstated the number by four.” We are moving towards a world that can be thought of as one globalcomputer. The big battle in computing is about who will control the operating system for that computer.
