airplane accident. Well, networks will produce the network accident. Many, in fact. A world primed for contagtion, Gates suggested, needs - and is missing - more and better gates. (Yes, here you can pause to double take at the serendipitously strange fact that the wealthiest citizen of our gated age is named Gates, just as the richest man in the era of pulling oil out of rocks was a “Rockefeller”) Connection demands systems to gaze ceaselessly for the smallest sign of assault or need for change or accidental shimmering movement of danger. Part of what made the Ebola response successful is that the response really was in the form of gates as we've come to understand them here, not walls. Protocols for biological reaction, for medical care, for epidemic monitoring, the urgent helicoperting in of support and aid and ideas. The gates assembled around the Ebola pandemic were its solution. Had it merely been walled off it would have spiked, grown, mutated and finally escaped.”The world,” Gates wrote, “needs to build a warning and response system for outbreaks.” This is true for all the outbreaks we face - whether they are disease or financial panic or terror. There will be, you can be sure, ignorant calls to build walls and not gates. This misses the point of networks. In an age of interconnection walls are nearly as dangerous as no walls. What matters is bulding topologies designed for gating, for milking power from the profound logic of networks we've seen at work. For decades after the 1929 financial crisis triggered an historic global depression, economists and politicians debated what had gone wrong. What had they missed? The world, it emerged, had been wired with an economic system designed rapid movement, but politicians and bankers had forgotten to put in the needed brakes. They had tried to run an industrial engine against the background of gasping political structures. Basic adjustment mechanisms - release valves for financial or currency pressures — had not bee
