So many people today think of computers only as a means to an end -- the thing they use to DO something. If they use a computer to watch a movie, it's not about the computer-- it's about the movie. If they use it to play a game, it's about the game. No matter what they do, it's NEVER about the computer. They don't think of "computers" as a subject, or as a thing to learn about or to know about.
Sure, you can use a computer without knowing what goes on inside it. And you can drive a car without understanding its internals too. But at least everybody knows that there IS such a thing as learning how a car works, and that there ARE auto mechanics and manufacturers, and that there would be no cars without them, and that it's a subject that you CAN study and make good use of the knowledge. With a computer, some people seem to think that it's just a thing that works by itself, and that nobody knows how it works, or needs to. That's what MAGIC is, but that's not what technology is.
It would be terrible if everyone needed to know how things work and repair them before being allowed to purchase them. Phones, TVs, Wii's, laundry machines, cars.
-CokeRobot mentioned paralleled parking. If people have a hard time with that, they should try it with a semi truck & armstrong steering. By the time I got a tractor with power steering I was good at it. Power steering messed me up for awhile until I quit oversteering.
