Michael Crichton, author of "Prey" "A nanorobot with a camera, sent into a blood vessel could change health care" "Such man made machines would be 1000 times smaller than the diameter of a human hair" "Many people, including myself, are quite queasy about the consequences of this technology," says K. Eric Drexler Our history of technology goes back 2 million years or more, started with making tools of bone & stone. Technology is a mixed blessing. Tiny camera the size of a particle of dust could fly over Iraq, send pictures back, & not be detected. It couldn't be shot down a bullet would fly right through it. Scientists are working on a new class of organism for more than 10 years. These organisms are designed by humans, but they will reproduce themselves and evolve. This discovery could be larger than the industrial revolution, we need to prepare now. The US government is spending more than $600 million a year on nanotechnology. These 21th century man made machines are on the order of 100 nanometers, or 100/billionth of a meter. These machines would be 1000 times smaller in diameter than the human hair. The potential benefits would be: tiny robots in the artery of humans able to cut away plaque; deliver powerful cancer fighting drugs to an individual cell, leaving healthy cells intact. Abilty to repair the knee, repair teeth, & cosmetic change to hair color. A personal computer could be painted on your arm. Convert trash dumps to energy. Move a house on the back of a million nanomachines. Nanotechniques are in use today to make sunscreens, stain resistant fabrics, and composite materials in cars. Experts predict that self producing machines are only a decade away, should begin to prepare now. History shows that man waits till an accident happens to pass a law. There are no laws on the books at present. With self reproducing machines, we can't afford to wait!
