This nervous system is the backbone of the Internet of things. Now imagine its future: trillions of devices—thermometers, cars, light switches, whatever—all connected through a gargantuan network of sensors, each with its own IP addresses, each accessible through the Internet. Suddenly Google can help you find your car keys. Stolen property becomes a thing of the past. When your house is running out of toilet paper or cleaning products or espresso beans, it can automatically reorder supplies. If prosperity is really saved time, then the Internet of things is a big pot of gold.
