gray goo
|
|
|
|
n. A hypothetical substance composed of sagan s of sub-micron-sized
|
|
self-replicating robots programmed to make copies of themselves out of
|
|
whatever is available. The image that goes with the term is one of the
|
|
entire biosphere of Earth being eventually converted to robot goo. This is
|
|
the simplest of the nanotechnology disaster scenarios, easily refuted by
|
|
arguments from energy requirements and elemental abundances. Compare blue
|
|
goo.
