I just started reading Michael Crichton's 'Prey'. I thought I would post this little blurb out of the introduction, These are two knowledgable scientists, Quote: "Within 50 -100 years a new class of organisims is likely to emerge. These organisims will be artificial in the sense that they will originally be designed by humans. However, they will reproduce, and will "evolve" into something other that their original form; they will be "alive" under any reasonable definition of the word... The pace of evoulutionary change will be extremly rapid...The impact on humanity and the biosphere could be enormous, larger then the industrial evolution, nuclear weapons, or environmental pollution. We must take steps now to shape the emergence of artifical organisims..." Doyne Farmer and Alletta Belin,1992 and Quote: " 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" K. Eric Drexler,1992 Chrichton talks about the mistakes made in the past, and our arrogance to not learn form them, and about how billions of dollars are being spent in nanotechnology researce, by both the US government and private companies. While the technology is mostly a materials tecnology, its potential goes far beyond that. Its out there now, used in sunscreens, stain resistant fabrics, selfcleaning window glass, and more. Chrichtons has real concerns over unscrupulous human behavoiur and greed, and the potential for diaster. The question of sustainablility of our selves and our planet is not in our control. We can do what we can to help the situation, but ultimately its going to be up to big business and governments as to whether or not we will survive.
