The Information Age is essentially an era driven by networks. In the physical realm, it began of course with the laying of railways lines on land and telegraph cables both overland and under the sea in the 19th century. Then, with the coming of electricity, radio, flight, rocketry and finally computers, the 20th century saw the complete saturation of our planet and its surrounding space by networks of unimaginable sophistication and complexity. It never ceases to amaze me that today one is able to stand or sail in the most remote corners of the world and hold in one’s hand a device capable of acquiring information from anywhere on the planet and giving access to nearly the entire sum of accumulated human knowledge. If he were around, William Blake would have managed a wry smile to see us hold infinity in our palm in this fashion. Such is the power and all-pervasiveness of networks in our times. However, to harness the full potential of physical and electronic networks and convert the information into practical wisdom and wealth requires one more crucial ingredient. That crucial capability is provided by human networks.
