I think part of the problem is that most of us here are naturally curious about things generally. Even if we don't need to know how something works, we attempt to find out anyway - not just in the engineering sphere, but in life as a whole. On the other hand, there are many who seem not to care about any of this, but go through life looking staight ahead, so to speak. It's an outlook which I admit to finding difficult to understand and sympathise with, but increasingly common nonetheless.
