Many people don't struggle to understand how to use computers. They don't understand them particularly well, but they don't struggle to understand them either.

Many people don't struggle to understand how to use computers. They don't understand them particularly well, but they don't struggle to understand them either. They rise to a level with the problems that they want to use the system to address and then... their understanding is adequate until something goes wrong. What possible motivation would they have to learn more? Okay, they might use a computer in their job - but inefficiency there is often their employer's problem, and considering you can't run arbitrary code on most companies systems (their IT policy generally excludes this) they benefit nothing from learning a programming language. What does that leave them with? A games machine perhaps, a glorified typewriter with some telecoms capabilities to all intents and purposes. The concept of computers as a general tool simply does not exist to many people. Consequently it's little wonder that they know next to nothing about them.
