Chris Phoenix and Eric Drexler, “Safe Exponential Manufacturing”, Nanotechnology, 15, 2004, pp 869–872. A self-confessed hacker adds a comment in the discussion at the end of Phoenix and Drexler’s paper: “To say that ‘runaway’ replicating nano-machines isn’t very likely is stupid, in my opinion. Why?
