Artificial Intelligence Ratings refer to the Persean Concord standard rating system by which Artificial Intelligences were rated and licensed for operation. The system was first outlined in 8,914 O.D. by Yazri research scientist Leaitsat Touargol to better assist in codifying the rapidly growing field of AI research. With the current ban on AI, resulting from the Runaway Thought Virus and the attendant widespread loss of life, all Artificial Intelligence research, development and implementation has been declared treason and carries a penalty of summary execution. Any AI found operating within the Cluster is to be destroyed on discovery, with all backups recursively destroyed as well.
