World "I
am endeavoring, ma'am, to construct a mnemonic circuit using stone
knives and bearskins." In the mid `90s, sages like MIT's Nicholas Negroponte told us to think about bits instead of atoms. Atoms were unwieldy hard goods."stuff" like steel and rock. You needed forklifts to move them. Bits were nimble little song and dance men that two-stepped around The Internet and recombined as everything from airline bookings to Britney Spears videos. Bits lived up to most of their promises, even though the results were often unintended and unwanted. Bits provided a clever new metaphor for academics and snake oil salesmen alike, greased the skids of commerce, pumped gas into an economic bubble and globalized knowledge and terror. Bits, in themselves, were simple minded. They had one decision to make.on or off: noble, actually, in this age of moral ambiguity, and ward politics at its best. Cajole enough of these pixel fairies to vote on a picture of a cat and you got a digital cat. Not a cat to warm your feet at night but a flat, phosphorescent facsimile. Here
Comes the Atoms Family The real itsy bitsies could be atoms behaving, in many cases, in the same way as bits: ganging up to become more powerful, replicating themselves, spreading wonder and viruses, creeping into places unnoticed. Atoms, like bits, have no code of ethics. This new material world promises both pain and pleasure. According to Eric Drexler, who coined the term nanotechnology, "This is a technology which can reasonably be described as extreme in all directions: extreme upsides, extreme downsides."
Buckytubes & Mighty Morfin' Airplanes You may have already heard about some new miracle fibers, but hold on. Last week, MIT got a grant from the US Army to create nanomaterials that can not only block out biological weapons but heal soldiers who get exposed. Mention buckminsterfullerines (buckyballs) or buckytubes and you may roll your eyes (What ever happened to geodesic dome)? But these microscopic carbon-based cylinders may form the basis of aircraft skins as light as aluminum but hundreds of times stronger than steel. Buckytubes are already in manufacture. Researchers at NASA's Langley Research Center say that airplane wings made of this sort of nanostuff will be able to change shape with changes in air pressure and temperature. Aircraft will be more efficient and able to adjust for maneuvers such as low speed takeoffs and landings. Morphing to a parachute would be nice. Nanocommerce
& Those Pesky Ants Designer drugs, corn and cats are already a reality to those who play with DNA. Scientists are working on pill that adds mechanics to biology that would swim around the body looking for bad shrimp, reaming out arteries, diagnosing illnesses and fabricating drugs on the fly. They could also take the form of the happy little scrubbing bubbles in detergent ads, sailing with the tides through the oceans and rivers, monitoring pollution and gobbling it up as it finds it. Water and air (the Pentagon is drooling over "smart dust") may not be the limit. One nanotech website has suggested that large public works and transportation projects could be aided by little digger machines that would be programmed to work like ants. Throw a bunch of these little buggers in a hole and watch them tunnel their way to the other side of the earth (what if they get there and are still hungry)? Far fetched? Last week researchers at UCLA announced that they have combined organic molecules and tiny pieces of metal to produce motors capable of moving things dozens of times larger than the device itself. Some of these machines would self-assemble. Why do I think of the "I Love Lucy" episode (a classic comedy in the US) where a conveyor belt goes wild in a factory and poor Lucy can't get control. Actually, this sort of self-assembly is common in biology and is quite beautiful when it takes the form of a seashell. Done right, this could open up a new era of environmentally friendly manufacturing which could eliminate polluting and toxic manufacturing processes. It doesn't take the imagination of an Arthur C. Clarke to list the potential nightmares these new technologies pose.from total loss of privacy to weapons that make anthrax spores seem like baby powder. Eric Drexler's Foresight Institute has developed a series of guidelines for keeping these gizmos from getting out of hand which include making devices that are dependent on broadcast transmissions for replication, routing the control signals around the devices in such ways that that cannot function independently (forming little terror cells) and programming termination dates into them. I am not making this up. The
