gray goo n. A hypothetical substance composed of sagans 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.

blue goo n. Term for `police' nanobots intended to prevent gray goo,
denature hazardous waste, destroy pollution, put ozone back into the
stratosphere, prevent halitosis, and promote truth, justice, and the
American way, etc. The term `Blue Goo' can be found in Dr. Seuss's "Fox
In Socks" to refer to a substance much like bubblegum. `Would you like to
chew blue goo, sir?'. See nanotechnology.
