Golden goo

Golden goo

Another member of the grey goo family of nanotechnology disaster scenarios. The idea is to use nanomachines to philtre 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.
