Definition and Uses
Most intelligent organic life-forms are limited in how many things they can be aware of and meaningfully think about at one time. Artificial systems can be designed to circumvent these limits, and doing so allows for the successful management and administration of truly large endeavors. Large-scale AI often serves in the role of "ship's computer" on large star-ships, and as an incredibly valuable administrative assistant in any government, but especially those at the scale of large modern nation-states and above.
History
Originally developed in the Empire of 1,000,000 Suns early in Era-0, and re-invented early in Era-1 in the Planetary League, large-scale AI is a technology capable of transforming the way large enterprises are carried out. The advent of these intelligences was known as "the singularity" in human-controlled space. The Corporate States made extensive use of large-scale AI in integrating the administration of a state with for-profit enterprise.
Examples
General Zarlok and the computer-god Troniac are both examples of large-scale AI. Large-scale AI was used extensively in the University of Aldebaran-2 to collate large data sets and discover hidden pieces of information.
