Gordon Knapp: If you pile all these electronic systems one on top of the other, sooner or later you're going to get a faulty transistor or a damaged rectifier, and then the whole thing just shuts down. Even computers suffer fatigue. They become erratic, they break down, just like overworked people. Prof. Groeteschele: Excuse me, but you're overlooking one important factor: Humans control those machines. Humans can see an error and correct it. Gordon Knapp: I'm sorry, sir, but you are misinformed. The fact of the matter is that these machines are so complex, and the mistakes they make are so subtle, that in a real war situation, you might not know whether the computer was in error, or telling you the truth.
