Imagine a great metropolis covering hundreds of square miles. Once a vital component in a national economy, this sprawling urban environment is now a vast collection of blighted buildings, an immense petri dish of both ancient and new diseases, a territory where the rule of law has long been replaced by near anarchy in which the only security available is that which is attained through brute power.... Yet this city would still be globally connected. It would possess at least a modicum of commercial linkages, and some of its inhabitants would have access to the world’s most modern communication and computing technologies. It would, in effect, be a feral city.
