Another
member of the grey goo family of nanotechnology disaster scenarios. The idea
is to use nanomachines
to filter gold from seawater. If this process got out of control we would get
piles of golden goo (the "Wizard's Apprentice Problem"). This
scenario demonstrates the need of keeping populations of self-replicating
machines under control; it is much more likely than grey goo, but also more
manageable. [MCH/josh, sci.nanotech,
