Goo, Golden (Midas Swarm)
A type of goo disaster associated with resource collection and concentration. The strange name comes from an early Information Age hypothetical scenario. The idea was to use self-replicating nanotech devices to filter gold from seawater. If this process got out of control the result would be piles of golden goo (a variant of the "Wizard's Apprentice Problem"). This is an Information Age version of the earlier Midas story from Europe's Agricultural Age. This scenario demonstrated the need of keeping populations of self-replicating machines under control. Golden Goo issues are much more common than Grey Goo, but because of the typically specialized nature of the replicators it is also more manageable. Golden Goo is sometimes named instead for the substance or element it manipulates (thus Carbon Goo, Aluminium Goo, etc.).
