I disagree a little bit. It is software vs hardware situation. I can work on my laptop all day long and get a lot of stuff done. I know how to use a laptop as long as it has an operating system the applications I need. That requires a lot of knowledge at several levels. How to use the OS, how to use a specific application. It also requires a physical dexterity keyboard, mouse buttons, eyes etc. It does not require much knowledge about what the computer is doing while I am working. If it stops working work stops. Same with a car, you can learn to operate it, and you have to learn to operate it in a safe and responsible manner. (in theory) If the car stops, I have no idea what to do. From the movies I have learned to "pop the hood" and look at the engine. Usually looking at the engine is not sufficient for it to start working again. So I have to call someone to fix it.
