I Turings "Computing machines and intelligence" (The ImitationGame) är det speciellt en mening som fastnat hos mig. Det är Turings definition av "intelligent behaviour": "Intelligent behaviour presumably consists in a departure from the completely disciplined behaviour involved in computation, but a rather slight one, which does not give rise to random behaviour, or to pointless repetitive loops. Det är "felen", det icke-perfekta, som definierar det intelligenta.
