> Automation doesn't make operators more careful. It makes them forget how to be. The more reliable the system, the less ready the human.
The entire premise of a system is that it removes the need for careful attention.
system: signal lights tell me whether or not I can pass through an intersection, so that I do not have to attend to potentially high speed traffic from a variety of directions.
system: the side my knife blade sits on my arched guide fingers, so that I do not have to attend to the edge of the blade or the location of my fingers.
