Not everyone is interested in the technicalities though. You wouldn't make a painter learn how paint was made before they could be allowed to daub a canvas so why force someone taking photographs into doing the same?
Happy accidents can be quite creative and are often more interesting photographs than those taken by the technically obsessed that miss a great moment because they're fiddling about with dials, fussing with DOF and worrying about ISO noise.
If the moment is captured it doesn't matter what mode the camera was in. I actually think the technical obsessives could be jealous when someone gets a great image in auto mode as they feel they didn't 'earn' it.
A camera with a telepathy option that knows what you were trying to achieve would be fantastic I reckon
