There is something mysterious that happens when we take large numbers of things that are fairly limited and connect them all together. When we take the dumb chip in each cash register in a store and link them into a swarm, we have something more than dumb. We have real-time buying patterns that can manage inventory. If we take the dumb chips that already regulate the guts of an automobile engine, and let them communicate an engine's performance to the mechanic of a trucking firm, those dumb chips can smartly cut expensive road repairs. (Mercedes Benz recently announced it is planning to embed a web server into its top-of-the-line model cars so technicians can spot service problems remotely.) When connected into a swarm, small thoughts become smart.
