"We are all repositories for genetically-encoded information that we're all spreading back and forth amongst each other, all the time. We're just lousy with information."
- Neal Stephenson

Director Jason Dill explained the rationale behind the construction of Vulcan 3:

"But who would watch the Guardians? How could we be sure this supranational body would be free of the hate and bias, the animal passions that had set man against man throughout the centuries?

...There was one answer. For years we had been using computers, giant constructs put together by the labor and talent of hundreds of trained experts, built to exact standards. Machines were free of the poisoning bias of self-interest and feeling that gnawed at man; they were capable of performing the objective calculations that for man would remain only an ideal, never a reality."

The games Machine from AE van Vogt's World of Null-A is a clear predecessor to the Vulcan 3 computer. Enjoy comparing Vulcan 3 to other computers large enough to run whole planets or societies: see the City Fathers from James Blish's Cities in Flight, Watchdog from Jack Haldeman's story of the same name, and Deep Thought from Douglas Adams' The Hitchhiker's Guide to the Galaxy.
