At Caltech over 40 years ago (Dec, 1959) Richard Feynman gave a talk
"There's Plenty of Room at the Bottom" - the challenge of manipulating
and controlling things on a small scale. His talk started the ball rolling on
the science of creating molecular devices that could compute, assemble and
replicate themselves.
Nanotechnology
manipulating matter at the atomic scale gets
its name from the measurement called a nanometer, or one-billionth of a meter,
the width of about four individual atoms. When we get down to this size, the
classical laws of physics change. Once atoms can be manipulated, it will be
possible to produce new materials with desired properties: smaller, stronger,
tougher, lighter and more resilient than anything that has ever been made.
An inflection point
Nanotechechnology is the next big revolution, an "inflection
point" which will change almost everything! It is developing to the extent
that practical applications are coming within the next few years, and certainly
with the next decade. NEMS (nano-electro-mechanical mechanical systems) are quickly becoming
practical, bringing ultra sensitive sensors and ultra strong actuators that
might replace damaged human tissue, or power tiny robots.
The holy grail of nanotechnology is self-assembly, which will soon be an
effective nano engineering tool. Self-assembly is nothing new: biology does it
all the time; in chemistry molecules team up to form structures. Indeed, the
concept of self-assembly grew out of attempts to aggregate molecules
spontaneously into specific configurations. Now, nanotech self-assembly is
attempting the same.
As
Nanotechnology advances into practicality, achievements will transcend and unite
such diverse sciences as physics, chemistry, biology and even computer science.
The conventional automation business will indeed be revolutionized.
Drexler's warning
In 1986, K. Eric Drexler published "Engines of Creation", the
groundbreaking Nanotechnology book. It described ways to stack atoms, assemble
machines much smaller than living cells, make materials stronger and lighter
than anything dreamed of today. Applications included better "skins"
for aircraft and automobiles, tiny devices that can travel along capillaries to
enter and repair living cells, the ability to heal disease, reverse the ravages
of age, make the human body stronger. The idea was born that we could make
machines the size of viruses. We could assemble these myriads of tiny parts into
intelligent machines, perhaps based on the use of trillions of nanoscopic
parallel-processing devices that would learn from previous experience.
Eric Drexler warned,
"There are many people, including myself, who are quite queasy
about the consequences of this technology for the future. We are talking about
changing so many things that the risk of society handling it poorly through lack
of preparation is very large."
Michael
Crichton's new novel
Drexler's
warning is included in the introduction to Michael Crichton's new
techno-thriller PREY. The author of "Andromeda Strain", "Jurassic Park"
and other best sellers, weaves a story about the perils of Nanotechnology. This
is combined with a technically realistic account of distributed intelligence,
self-organizing systems and emergent behavior the subjects Dick Morley has
been discussing at his Santa Fe Chaos conferences for several years.
PREY brings to mind Bill Joy's well-known Wired article, "Why the
Future Doesn't Need Us." He warned, "Our most powerful 21st-century
technologies robotics, genetic engineering and nanotech are threatening
to make humans an endangered species."
Michael Crichton doesn't allow the reader to relax with the feeling that
the danger is fictional the book includes an introduction to emphasize the
direct link to reality. Drexler's warning (above) is included, as well as an
extract from a Santa Fe Institute paper by J. Doyne Farmer and Alletta d'A.
Belin, "Artificial Life: The Coming Evolution". Here is that quote:
"Within fifty to a hundred years a new class of organisms is likely
to emerge. These organisms will be artificial in the sense that humans will
originally design them. However, they will reproduce, and will evolve into
something other than their initial form; they will be "alive" under
any reasonable definition of the word. The pace of evolutionary change will be
extremely rapid. The advent of artificial life will be the most significant
historical event since the emergence of human beings. The impact on humanity and
the biosphere could be enormous, larger than the industrial revolution, nuclear
weapons, or environmental pollution. We must take steps now to shape the
emergence of artificial organisms; they have potential to be either the ugliest
terrestrial disaster, or the most beautiful creation of humanity."
PREY
is the story of a cloud of nanoparticles that has escaped from the lab
self-sustaining, self-reproducing micro-robots. The cloud is intelligent and
learns from experience. It is "alive" and has been programmed as a
predator. Humans are its prey. It defeats efforts to kill it through
self-organizing, emergent behavior and genetic algorithms. It evolves swiftly
and becoming more deadly with each passing hour. The story is fictitious, but
the underlying technology is real.
PREY is a good book - read it!
