    Based on the following truly remarkable visions, I think a quiet
    revolution is emerging that, over the next few years, could dwarf the
    size and complexity of the Internet as we know it today. Some analysts
    have ventured to predict that trillions of embedded measuring devices,
    each with sensors, a processor, and radio, will be networked together to
    provide a nervous system for the physical world.

    This reminds me about the importance of the Mt. Diablo Open R&D Wireless
    Testbed (aka; digital blackboard) for demonstrating how the
    Software-Defined Radio architecture can evolve into "environment-aware
    Cognitive Radios" with dynamic knowledge links to distributed networks
    of sensors/actuators and the Internet for remote monitoring and control
    (i.e., a 30 mi. radius Societal-scale Information System).

         "In the next decade, we are going to add sensory organs to our
         devices and networks. Processing plus sensors will set the stage
         for the next revolution—interaction. We mean the interaction of
         electronic devices with the physical world on our behalf. Sensors
         do not just have to stop at mere sensing. The sensor decade will
         really be a sensor/effector decade, where devices will not only
         observe things; they will also manipulate them.”

         "In the next century, planet earth will don an electronic skin. It
         will use the Internet as a scaffold to support and transmit its
         sensations. This skin is already being stitched together. It
         consists of millions of embedded electronic measuring devices:
         thermostats, pressure gauges, pollution detectors, cameras,
         microphones, glucose sensors, EKGs, electroencephalographs. These
         will probe and monitor cities and endangered species, the
         atmosphere, our ships, highways and fleets of trucks, our
         conversations, our bodies--even our dreams.

         Ten years from now, there will be trillions of such telemetric
         systems, each with a microprocessor brain and a radio. Consultant
         Ernst & Young predicts that by 2010, there will be 10,000
         telemetric devices for every human being on the planet. They'll be
         in constant contact with one another. But the communication won't
         be at our plodding verbal pace. ''Fifty kilobits per second is
         slow,'' huffs Horst L. Stormer, a Nobel prize-winning physicist
         employed by Lucent Technologies Inc.'s Bell Laboratories and
         Columbia University. Machines will prefer to talk at gigabit speeds
         and higher--so fast that humans will catch only scattered snippets
         of the discussion.

         What will the earth's new skin permit us to feel? How will we use
         its surges of sensation? For several years--maybe for a
         decade--there will be no central nervous system to manage this vast
         signaling network. Certainly there will be no central intelligence.
         But many scientists believe that some qualities of self-awareness
         will emerge once the Net is sensually enhanced and emulates 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. That has produced an evolutionary leap in software: The
         ''open source'' movement that spawned the Linux operating system.
         The Linux world behaves as an ecosystem--''a self-correcting
         spontaneous order,'' as open-source pioneer Eric Raymond describes
         it in his Net manifesto, The Cathedral and the Bazaar. Through
         collaboration, this community can push past the technical barriers
         to machine intelligence."

         He began wondering how he might use technology to solve
         society's problems. "The complexity that mankind is facing is
         getting greater and greater", he said to himself, "so our
         problems are getting more complex, and the time we have to
         deal with them is getting shorter and more urgent. Is there
         anything I can do to contribute to mankind's ability to cope
         with compexity and urgency? The more he though about it the
         more it moved him. "That," he concluded, "would be a terriffic

       * Edward Wilson wrote (Consilience - The Unity of Knowledge. New
         York, 1998: Knopf. 332 pp.):

         "A great deal of serious thinking is needed to navigate the
         decades immediately ahead … . only unified learning,
         universally shared, makes accurate foresight and wise choice
         possible. … we are learning the fundamental principle that
         ethics is everything."

         Fortunately, the exponential growth of knowledge is several
         times larger than the exponential growth in the world economy
         that combines the effects of population gains and increases in
         individual economic productivity. Within reach is the
         capability to design the future instead of trying to predict
         it or lurching toward a less-than-optimum future along a
         "business-as-usual" path.

         The strategy for pursuit of this vision will be information
         based, knowledge guided, stakeholder driven, and human
         centered. It will develop four dimensions of bootstrapping:

            * discovery (through research),
            * integration (through interdisciplinary
            * dissemination (through education that becomes
              life-long learning), and
            * application (through cooperation among academia,
              business and industry, the several levels
              ofgovernment, and nongovernmental organizations)

         Wrestling with the complex problems of providing a sustainable
         world for future generations is the most crucial challenge
         society and governments face today and into the new
         millennium. Success in developing effective strategies to
         confront this formidable challenge will require novel forms of
         cooperation and collaboration between and among institutions
         across all jurisdictional boundaries. While processes for
         moving toward this desired future condition are taking place,
         their evolution is being accelerated by the rapidly increasing
         knowledge in science, engineering and technology—and by the
         emergence of increasingly practical ways for disseminating and
         using data and information for the creation of knowledge.

         These trends strongly indicate that it is timely for nations
         of the world to galvanize the scientific and technological
         capabilities of their institutions into concerted action for
         advancing research and monitoring for managing their economic,
         social and ecological systems in a sustainable manner across
         continental scales. Working in partnership to carry out this
         common task will further galvanize our institutions to
         confront successfully the complex sustainability challenges of
         the new millennium.
