My mom doesn't want to be a "liberated computer user", she wants to use her phone to watch youtube, see pics of her grandkids and listen to music, she doesn't even care about having social networks. You're projecting your own personal interests into others, the world contains multitudes, not everyone wants to understand every little detail of how computers work.
For most people computers are like cars, they couldn't care less about how they work, as long as they can use them to take them from place A to place B.
This comment is mildly ironic because the same kind of argument has often been used around cars. Do you want to be merely a car driver, or do you want to be a car "operator", who understands (to some level of abstraction) what happens "under the hood" when you manipulate the levers and wheels in your car?
Different strokes for different folks, but never forget, knowledge is power.
