Exactly.
Here's another thought: Electronic technology has taken repair out of the hands of the ordinary person and placed it in the hands of those with special training. Take the typewriter as an example. We can easily see what happens when we strike a key. The arm bearing the appropriate symbol at its tip strikes the ribbon and the paper behind it, creating a visual image. Let's say that one of the symbols, as we strike the key, fails to print. We check the key's arm and discover that it's bent slightly out of shape. We straighten it and, voilà, it functions again.
A computer keyboard, on the other hand, is completely different. When we strike a key, we don't see what all goes on to make the symbol appear on the computer screen. If we discover a bug, most of us are powerless to fix it ourselves. We have to rely on those with special knowledge who have learned and employ a special computer language.
The electronic age has hidden the physics of what produces a result. In most cases, simply taking an electronic item apart no longer lets us discern why it has malfunctioned.
