World of Goos

Gray goo has been a major obstruction to reasonable discussion about nanotechnology ? perhaps, the reason why some scientists have fought so hard (despite little evidence) to avoid conceding that molecular manufacturing is possible.

Pioneering nanotechnology theorist Dr K Eric Drexler had cautioned against self-replicating machines in his book Engines of Creation (1986). The idea became known as ‘grey goo’ and inspired a generation of science fiction authors. Drexler said that nanotechnology-based creation could be completely safe from out-of-control replication, but misuse of molecular manufacturing remained a significant risk.

The various goos

Gray Goo or Grey Goo:  A notorious fear that is an offshoot of MNT (molecular nanotechnology). The idea is that a small molecular manufacturing system could give rise to large groups of destructive nanites — believed to be created by accident. They are nano-scale or "atomic-precision" robots (nanobots) capable of precise, molecular control over chemical reactions, programmed to make unlimited copies of themselves, and capable of surviving in a wide range of environmental conditions. If left uncontrolled, they would basically turn everything they touch into more of themselves, or consume and digest it for energy (ecophagy).

Gray goo has been a major obstruction to reasonable discussion about nanotechnology — perhaps, the reason why some scientists have fought so hard (despite little evidence) to avoid conceding that molecular manufacturing is possible.

Blue Goo: Opposite of Grey goo. Beneficial tech, or "police" nanobots. The trouble with blue goo is that it could easily make too much of itself — and it's hard to clean up, even to replace with a later version.

Green Goo: Nanomachines or bio-engineered organisms used for population control of humans. Would most probably work by sterilizing people with the help of harmless infections.

Golden Goo: Another member of the grey goo family of nanotechnology disaster scenarios. The idea is to use nanomachines to filter gold from seawater. If this process got out of control we would get piles of golden goo.

Khaki Goo:
Vast army of destructive nanites — created by accident. If left uncontrolled, they will basically convert everthing they come across into more of themselves, or consume and digest it for energy.

Pink Goo: It refers to Old Testament apes whose purpose is to be fruitful and multiplying, crowding the universe with many more such apes, unmodified.

Red Goo: Deliberately engineered and released destructive nanotechnology, as opposed to accidentally created grey goo.

LOR Goo: Lake Ocean River. Nanites that both clean up and harvest the oceans, rivers, and lakes — gathering raw materials, such as precious metal atoms, and cleaning up spills, old waste, wrecks, and other dangerous sites. A simple programming error could turn LOR Goo into Gray Goo.
