This skin is being stitched together. I consists of millions of electronic measuring devices, such as thermostats, pollution detectors, cameras, EKGs. These will probe and monitor cities and endangered species, the atmosphere, and our ships, highway vehicles, and our bodies. For a decade or longer there will be no central nervous system to manage this vas signaling network. And there will be no central intelligence.Bu we believe tha some qualities of self-awareness will emerge once the Ne is sensually enhanced and emulated the complexity of the human brain. Sensuality is only one force pushing the Ne toward intelligence. An eerie symbiosis of human and machine effor is also starting to evolve. The Interne creates a channel for thousands of programmers around the world to collaborate on software developmen and debugging. Through collaboration, this community can push pas the technical barriers to machine intelligence. And though silicon networks today look nothing like the brain, nodes of the Ne have begun to function as neuron. Researchers have already tackled complex computing problems, suchas interpretinginterstellarradio signalswith abou amillionPCsworking inconcert. Before long, discrete microprocessors will probably be kni ed together into ad hoc distributed computers. Don’ think of these as PC networks.
