Depends on the precise parameters; for example if a grey goo nanobot can kill ten other grey goo nanobots in the time it would take to make one, then the sphere will soon die out. Of course it could do a lot of damage in that time. The important point is that these detailed implementation issues are entirely ignored by the nanotech doomsayers; just as many similar issues are ignored by the nanotech utopians.
