Within fifty to a hundred years, a new class of organisms is likely to emerge. These organisms will be artificial in the sense that they will originally be designed by humans. However, they will reproduce, and will "evolve" into something other than their original form; they will be "alive" under any reasonable definition of the word. These organisms will evolve in a fundamentally different manner… The pace… will be extremely rapid… 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… Doyne Farmer and Alletta Belin, 1992 There are many people, including myself, who are quite queasy about the consequences of this technology for the future.
K. Eric Drexler, 1992
Introduction
Artificial Evolution in the Twenty-first Century The notion that the world around us is continuously evolving is a platitude; we rarely grasp its full implications. We do not ordinarily think, for example, of an epidemic disease changing its character as the epidemic spreads. Nor do we think of evolution in plants and animals as occurring in a matter of days or weeks, though it does. And we do not ordinarily imagine the green world around us as a scene of constant, sophisticated chemical warfare, with plants producing pesticides in response to attack, and insects developing resistance. But that is what happens, too.
If we were to grasp the true nature of nature-if we could comprehend the real meaning of evolution-then we would envision a world in which every living plant, insect, and animal species is changing at every instant, in response to every other living plant, insect, and animal. Whole populations of organisms are rising and falling, shifting and changing.
