Interviewer: HAL, You have an enormous responsibility on this mission, in many ways perhaps the greatest responsibility of any single mission element. You're the brain and central nervous system of the ship, and your responsibilities include watching over the men in hibernation.

HAL: Let me put it this way, Mr. Amor. The 9000 series is the most reliable computer ever made. No 9000 computer has ever made a mistake or distorted information. We are all, by any practical definition of the words, foolproof and incapable of error.
