	Grey goo
		Grey goo refers, usually in a science fictional context, to a hypothetical human extinction event involving nanotechnology, in which out-of-control self-replicating robots (Von Neumann machines) consume the Earth while building more of themselves.
		In a worst-case scenario, all of the matter in the Galaxy could be turned into goo (with "goo" meaning a large mass of replicating nanomachines lacking large-scale structure, which may or may not actually appear goo-like), killing the Galaxy's residents.
		Assuming a nanotechnological replicator is capable of causing a grey goo disaster, safety precautions might include programming them to stop reproducing after a certain number of generations, or designing them to require a rare material that would be sprayed on the construction site before their release.

	Grey Goo
		Grey goo, a term coined by nanotechnology pioneer Eric Drexler, refers to a hypothetical end-of-the-world event involving nanotechnology in which out-of-control self-replicating robots consume all life on Earth while building more of themselves (a scenario known as ecophagy).
		In a worst-case scenario, all of the matter in the universe could be turned into goo (with "goo" meaning a large mass of replicating nanomachines lacking large-scale structure, which may or may not actually appear goo-like), killing the universe's residents.
		One convenient analogy for the grey goo problem is to consider bacteria as the most perfect example of nanotechnology; as they have not reduced the world to grey goo in 4 billion years of evolution, it is unlikely that some artificial construct will manage to do so.

	Grey goo - Wikipedia, the free encyclopedia
		Grey goo refers to a hypothetical end-of-the-world scenario involving molecular nanotechnology in which out-of-control self-replicating robots consume all living matter on Earth while building more of themselves (a scenario known as ecophagy).
		Thus a living goo could be a multicellular organism that obtains its raw materials to grow through ecophagy, and then grows through a process of exponential assembly such as cell division.
		One fanciful depiction of a grey goo crisis was in an episode of the Gargoyles animated series where the protagonists face an advanced form of artificially intelligent nanotechnology.

	Nanotechnology: Grey Goo is a Small Issue
		Fear of runaway nanobots, or “grey goo”, is more of a public issue than a scientific problem.
		Grey goo as a result of out of control nanotechnology played a starring role in an article titled "The Grey Goo Problem" by Lawrence Osborne in today's New York Times Magazine.
		This article and other recent fictional portrayals of grey goo, as well as statements by scientists such as Richard Smalley, are signs of significant public concern.

	Grey Goo - An Exponentialist Explanation
		Grey goo (based on such assemblers) is the generic name given to a theoretical, and quite deadly, threat to all life.
		Each grey goo is a potentially deadly replication bomb, and could spread the "seeds" of other grey goos very quickly as described by Drexler.
		If you forget the dreaded grey goo scenario for a moment, and focus on the impact of nanotechnology on the future of the process of evolution for Earth species, you might see that grey goo is not really the threat.

	Turns of Phrase: Grey goo
		Mr Joy goes as far as saying that there are some areas of research we ought not to pursue, because the consequences might be so dire.
		The nightmare is that combined with genetic materials and thereby self-replicating, these nanobots would be able to multiply themselves into a “gray goo” that could outperform photosynthesis and usurp the entire biosphere, including all edible plants and animals.
		Grey goo is a wonderful and totally imaginary feature of some dystopian sci-fi future in which nanotechnology runs riot, and microscopic earth-munching machines escape from a laboratory to eat the world out from under our feet.

	Nanotechnology pioneer slays 'grey goo' myths
		Talk of runaway self-replicating machines, or “grey goo”, which he first cautioned against in his book Engines of Creation in 1986, has spurred fears that have long hampered rational public debate about nanotechnology.
		Eric Drexler, also warns that scaremongering over remote scenarios such as “grey goo” is taking attention away from serious safety concerns, such as a deliberate abuse of the technology.
		Science fiction writers focused on this idea, and ‘grey goo’ became closely associated with nanotechnology, spreading a serious misconception about molecular manufacturing systems and diverting attention from more pressing concerns.

		Gray goo (or, in British spelling, "grey goo") is a term used to describe what life on our planet might become if
		The possibility of all of us becoming a lifeless conglomeration of gray goo, whether by accident or by robotic intent, is considered exceedingly unlikely.
		A significant argument against the possibility of a gray goo situation is that engineers should be able to build in limiting conditions for self-replication.

		2:45pm PST: We are still in the process of handling the recent attack of grey goo, but teleportation and other in-world behavior should be back to normal.

	Background 2: Accidents, Malice, Progress, and Other Topics
		It is hard to imagine a practical application of nanotechnology that would demand independent replicators; for its success or practicality.
		The gray goo threat, though a fine symbol of the destructive power of nanotechnology, is likely to receive too much attention rather than too little.
		A policy that treats it as primary will be a policy that misdirects efforts and may lead to dangerous decisions, such as attempting to block advances and thus relinquishing leadership to others with fewer concerns.

		The grey goo scenario was first posited by Drexler in his seminal book on nanotechnology, Engines of Creation, in which he describes how small nano-scale robots could be built to replicate themselves using any organic material.
		Drexler regrets having mentioned the grey goo scenario since for some strange reason this put many investors off nanotechnology and prompted politicians to put the brakes on some research.
		He also reassuringly points out that grey goo really is less of a concern than other potential problems with the technology such as nanoterrorism and nanoviruses.

		Aristoi by Walter Jon Williams is a brilliant Space Opera that involves a grey goo catastrophe some time in the past, extensive use of nanotech, and some freaky social engineering.
		I think the so-called "grey goo" scenario is far less of an immediate threat than its biological/genetic engineering counterpart.
		One of the ways the world ends in the Invisibles comic book series is when nanotech grey goo attacks the earth on December 22, 2012, tying together a couple different apocalypse theories rather well.

		He said in the article that he doesn't fear grey goo, has never used that term, and he doesn't believe that self replicating robots will devour our planet.
		He says the Royal Society and the Royal Academy of Engineering are conducting a joint study on nanotechnology which will help separate the facts from the science friction.
