Grey Goo!

My buddy from Oni Press, Cory Casoni, IM’d me the other day with this!
Grey 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—a scenario known as ecophagy (“eating the environment”).
The term grey goo is usually used in a science fiction context. 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). The disaster is posited to result from a deliberate doomsday device, or from an accidental mutation in a self-replicating nanomachine used only for other purposes, but designed to operate in a natural environment.
The term grey goo was coined by nanotechnology pioneer Eric Drexler in his 1986 book Engines of Creation.[1]
So I ran out to Powell’s and picked up Drexler’s book and Greg Bear’s Blood Music. Great stuff! It’s like we’re predicting the future!
