Self-Replicating Atomic-Size Machines, By James Bell
Another cutting-edge field of research with an exponential growth rate is nanotechnology -- the science of building "machines" out of atoms. A nanometer is a distance one-hundredth-thousandth the width of human hair. The goal of this science is to change the atomic fabric of matter -- to engineer "machine-like atomic structures" that reproduce like living matter.
In this respect, it is similar to biotechnology, except that nanotechnology needs to literally create something like the non-organic version of DNA to drive the building of its tiny machines.
As University of Texas Professor Angela Belcher explains, "We're working out the rules of biology in a realm where nature hasn't had the opportunity to work." Belcher is combining genetically modified proteins with semiconductors in the hope of using proteins to do the "building" of the non-living nanostructure. The technique is a hybrid of biotechnology and nanotechnology. What would take millions of years to evolve on its own, "takes about three weeks on the bench top," says Belcher.
Machine progress is knocking down the barriers between all the sciences. Chemists, biologists, engineers and physicists are now finding themselves collaborating on experimental research. This collaboration is best illustrated by the opening of Cornell University's Nanobiotechnological Center and other such facilities around the world. These scientists predict a breakthrough around 2005 to 2015 that will open the way to molecular-size computing -- allowing for exponential technologic progress to race toward infinity.
Signs of the 'Coming Singularity' By Gar Smith
Some of the scientific "breakthroughs" expected in the next few years promise to make cloning and xenotransplantation (the introduction of genes from one species into another) seem rather benign. At least when scientists plant a spider gene in a goat or insert pig cells into a human brain, they are dealing with all-natural ingredients. In the Brave New World of the Coming Singularity, the merging of technology and nature has already yielded some disturbing progeny. Consider these examples:
*Human embryos have been successfully implanted and grown in artificial wombs. (The experiments were halted after a few days to avoid violating in-vitro fertilization regulations.)
*Researchers in Israel have fashioned a "bio-computer" out of DNA that is capable of handling a billion operations-per-second with 99.8 percent accuracy. Reuters reports that these bio-computers are so minute that "a trillion of them could fit in a test tube."
*IBM has built a video screen whose images appear so true-to-life that "the human eye finds [the video images] indistinguishable from the real thing."
*In England, University of Reading Professor Kevin Warwick has implanted microchips in his body to remotely monitor and control his physical motions. During Warwick's Project Cyborg experiments, computers were able to remotely monitor his movements and open doors at his approach.
*Engineers at the US Sandia National Labs have built a remote-controlled spy robot equipped with a TV scanner, microphone and a chemical micro-sensor. The robot weighs one ounce and is smaller than a dime. Lab scientists predict that the micro-bot could prove invaluable in protecting "US military and economic interests."
*US scientists have built a machine that, when released into the environment, powers itself by feeding on the bodies of snails and other living creatures.
*In April 2001, scientists built a robotic fish that was guided by the brain of an eel. The Washington Post heralded the grotesque achievement with the headline: "Scientists Start to Fuse Tissue and Technology in Machines."
*In February 2001, MIT researchers successfully tested a robotic fish controlled by a microprocessor and powered by the muscle tissues stripped from a frog.
Vernor Vinge's Vision, By Gar Smith
The nonprofit Singularity Institute for Artificial Intelligence (SIAI, siginst.org) exists "to bring about the Singularity -- the technological creation of greater-than-human intelligence." SIAI believes that the creation of "computer-based 'artificial intelligence' [will]... result in an immediate, worldwide and material improvement to the human condition."
Vernor Vinge, the originator of the Singularity concept, is not so sanguine. "When greater-than-human intelligence drives progress, that progress will be much more rapid," Vinge conceded during his famous 1993 speech at a NASA symposium. "We can solve many problems thousands of times faster than natural selection."
"How bad could the Post-Human era be?" Vinge wondered. "Well... pretty bad. The physical extinction of the human race is one possibility." Another possibility he proposed was that, "given all that such technology can do, perhaps governments would simply decide that they no longer need citizens!
"The first ultra-intelligent machine is the last invention that man need ever make (provided that the machine is docile enough to tell us how to keep it under control)." Because ultra-intelligent machines could design even better machines, Vinge predicted an "intelligence explosion" in the near future.
