power operates as much through light pulses running through fiber optic webs as it does in any physical sense. Think of the most influential geopolitical forces. The most lethal militaries. The greatest new commercial or financial efforts. All now depend on and are nearly defined by their fluency with different sorts of connection.

All of these systems are defined by relations. Their power comes from the number, the type and the speed of the connections they hungrily establish and then use. Networks don’t merely speed up our markets, our news, or our innovation - they revolutionize the nature of their power. Broad-based interconnection can cause and even determine events. These expanding, ever-thicker webs of data and linkage can be mapped, and tak
