Sometimes I get the impression that they are so used to understanding things, and doing things based on that understanding, that they don't have experience and confidence with systems that no human likely even can understand fully.
These are people who can process input from their entire body at once while riding a skateboard. They can draw or sculpt or carve. They can play instruments and drive cars... But they're terrible with computers.
They are afraid to touch anything thinking the settings panel is full of instantly catch fire buttons. They touch the mouse with uncomfortable body language, like it's a pocket knife that has an overcomplicated spring mechanism you don't trust.
They don't try to solve problems themselves because they have lots of anxiety when they go near one.
In real life it doesn't work to say "Yeah I have no idea how any of this works but there's an undo button".
These highly capable people also seem to have boredom issues too. They can physically build something a faster than they can design and 3D print it. It probably doesn't feel as exciting when you can already do everything the machine can.
Apple is considered the top company for n00bs, but they rely heavily in gestures and your own memory. I suspect that it's not an easy system for "idiots" as some think, it's a system for people who aren't comfortable with indirection and like direct control.
Everyone always thinks users are idiots, but they can all do so much that I can't. I suspect they're just used to freedom living in the moment, and are strongly tactile and connected to their body, so that they don't really feel the artificial abstractions as real things they trust, plus they have active minds and are distracted by not understanding how something works, instead of just accepting it as probably some nonsense that a drunk coder made up that can't be changed because legacy.
