原文

Planet Earth will do an electronic skin in the not-too-distance future. It will use the internet as a scaffold to transmit its sensations. This skin is being stitched together. It 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 vast signaling network. And there will be no central intelligence. But we believe that some qualities of self-awareness will emerge once the Net is sensually enhanced and emulated the complexity of the human brain。

Sensuality is only one force pushing the Net toward intelligence. An eerie symbiosis of human and machine effort is also starting to evolve. The Internet creates a channel for thousands of programmers around the world to collaborate on software development and debugging. Through collaboration, this community can push past the technical barriers to machine intelligence。

And though silicon networks today look nothing like the brain, nodes of the Net have begun to function as neuron. Researchers have already tackled complex computing problems, such as interpreting interstellar radio signals with about a million PCs working in concert. Before long, discrete microprocessors will probably be knitted together into ad hoc distributed computers. Don't think of these as PC networks. The terminals would just as likely be cell phones of palm-like devices, each one far smarter than today's heftiest desktops. We may think of this as a whole ecology, an information environment that's massively connected。

Humanity is now preparing to cast its net across the solar system. At a NASA laboratory in California, scientists are devising a version of the Internet called Inter Planet that will weave the moon, Mars, and some asteroids and comets into the earth's expanding nervous system。

Today's communications between earth and unmanned probes are expensive, proprietary, and complex. With Inter Planet, we can simplify everything, cut costs, and engage the public more effectively. Then, the earth's telemetric body will span the reaches of the solar system. The Net may not experience all the human thrills of exploration, but it will feel some tingles up and down its spine.
