In Asimov's fiction it is the authoritative global computing resource — consulted by governments, by individuals, and ultimately by humanity itself. Its descendants in the real world are the large-scale inference systems that answer questions at population scale.

Multivac is the fiction of universal question-answering at a time (the 1950s–70s) when the real computer was a mainframe operated by trained specialists.

The Orange Pill Asimov volume treats this as the defining skill-shift of the current era: when answers are cheap, question formulation becomes the scarce resource.
The contemporary reader may recognize Multivac in every query-answering AI system from search engines to chat assistants. The differences are instructive: Multivac was singular, canonical, and authoritative; modern systems are plural,
