With outposts all over the internet, scientific idealists promote a positive, almost religious, vision of these emerging technologies' transformative impact on human evolution. The Global Resource for Orthotics and Prosthetics provides links to numerous corporate and informational Web sites related to these currently available prostheses. Cutting edge prosthetic research promises more miraculous possibilities. Cutting edge prosthetic research, with links to many research Web sites, is summarized at BusinessWeek online . These prosthetic innovations of techno-science encourage a fantastic dream of immortality through gradual replacement of all body parts as they become diseased or worn out.
Biotechnology goes even further.
Rather than provide a new artificial body, biotechnologists want to prevent or cure disease by managing the body's biological processes in ever greater detail, leading to perfect health. Other mind-boggling projections can be found at Nanotechnology magazine . Using genetic sensors, these nanobots will hunt down and destroy every cancer cell. Other diseases will also be subject to nanobot attacks. For example, differently programmed nanobots will be sent into the body to loosen tiny bits of artery plaque and clear out clogged blood vessels.
