.Grey goo (alternatively spelled gray goo) is a hypothetical end-of-the-world scenario involving molecular nanotechnology in which out-of-control self-replicating robots consume all matter on Earth while building more of themselves,[1][2] a scenario known as ecophagy ("eating the environment").^ Following (0) Grey goo — a hypothetical end-of-the-world scenario in which out-of-control self-replicating robots consume all matter on Earth while building more of themselves Folkert (25,747 views) Filed under roxy paine , machine art , eric drexler .

.Self-replicating machines of the macroscopic variety were originally described by mathematician John von Neumann, and are sometimes referred to as von Neumann machines.^ Gray goo is the scenario popularized in Michael Crichton's novel Prey , in which tiny self-replicating nano-machines take over the world.

 .The term grey goo was coined by nanotechnology pioneer Eric Drexler in his 1986 book Engines of Creation.^ We can thank Eric Drexler of MIT for the term nanotechnology which he coined in 1981, and the concept of grey goo in 1986 - though not the disproportionate attention and hysteria.

 .In the worst postulated scenarios (requiring large, space-capable machines), matter beyond Earth would also 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).^ 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.

 ^ But big-frontal-lobes like nanotechie Eric Drexler and Sun Microsystems cofounder Bill Joy have predicted that self-replicating nano-robots will eventually run amok, converting everything into `gray goo.'"
