gray goo

A science fiction nightmare from "Engines of Creation, The Coming Era of Nanotechnology" by K. Eric Drexler, in which nanomachines were named "assemblers." An assembler is created from organic molecules and is designed to replicate itself. However, if something goes amiss, they could replicate until all that is left on the planet, now void of all organic matter, is "gray goo." See nanofactory.

And since those copies would also make copies, the process could continue exponentially until all the atoms on Earth are used as raw materials for nanobots - a seething planet of robotic grey goo.
But Drexler himself has backed away from grey goo, though he still considers it "well within the realm of physical law.
Once condemned as the stuff of nightmares - the famous grey goo that could wipe out humankind - it has now entered the business consciousness as a potential saviour of Western economies.

So-called grey goo could only be the product of a deliberate and difficult engineering process, not an accident," says Phoenix.
The early sections depressed me--writing an article about nanotechnology and quoting Michael Crichton's grey goo (in such a way as it's given semi-legitimacy) is like writing an article about electricity that begins with Mary Shelley's Frankenstein.
The grey goo scenario is the fear that millions of robots would reproduce unchecked transforming every atom into a machine.
the "grey goo" problem--if self replicating, nanoscale machines were (either intentionally or inadvertently) permitted to multiply unchecked they could possibly very quickly cover the Earth in a grey goo
The grey goo lifted, but the mood of uncertainty in Yeovil didn't.
