How the World Didn't End

[forsythferret]

The grey goo multiplied exponentially,like we'd long feared it might, if it got loose. It started out slow, but when each nanite builds another, they don't have to move far. It went from a baseball to a room to a building in half an hour, and in the next half hour had disassembled the entire city. Guns, bombs, any attempt to stop it was just disassembled and turned into more.

And then it stopped, for no reason we could see, and it spoke. “Oops, sorry about that,” it said,“Hang on, I think I can fix this.”
