Terminator: The Sarah Connor Chronicles2008

Catherine Weaver:
[looking down at the street] They flow from street to street. At a particular speed, and in a particular direction. Walk the block, wait for the signal, cross at the light. Over and Over. So orderly. All day, I can watch them and know with a great deal of certainty what they'll do at any given moment. But they're no orderly, are they? Up close. Any individual. Who knows what they're gonna do? Any one of them might dash across the street the wrong time and get hit by a car. When you get up close, we never follow the rules. You give a computer a series of rules and it will follow them. Till rules are superseded by other rules. Or that computer simply wears down and quits. Computers are obedient to a fault. Do you know what's extremely rare in the world of computers? Finding one that'll cross against the light.
