In a lot of the discussions I'm seeing on here, it seems like a lot of the disagreement is around the question of whether it is reasonable to expect that people should be expected to know how their tools work. I would have to take the position that people should have some in-depth knowledge of how their tools work. Why? All abstractions are leaky. Would you expect a carpenter to use a (powered) saw without knowing how it is designed and how the blade is driven (for safety and making smooth cuts)? Would you expect a radiologist to interpret x-ray photos without having an understanding of the impact that different energy (KeV) radiation and film/sensor technology has on the resulting image?
