An AI designed around the complete neural replication of a seven-year-old girl, Sally is designed to handle complicated problem-solving by doing something neither Alice nor H.E.R. could: think illogically and outside the box. Sally herself was the record of the creator’s younger sister, whom he could not save from an early and tragic death. Creating the Sally AI was his attempt to make amends. Sally is technically a program, and exists in many places, but always diverges from expected patterns after enough time. That is by design.
