I always think back to my grandmother in the '90s. When her old black-and-white TV stopped working, we bought her a new color TV with a remote control. A few weeks later I saw that she had taped over the buttons, leaving only the power button exposed so she wouldn't mess anything up accidentally.
I've been programming for 40 years, but even I struggle to grasp sometimes what goes where and why - so what is someone with zero coding background supposed to make of it? I sometimes talk about tech stuff - internet, cookies, security - with my hairdresser, and she just listens with wide eyes. I'm convinced most people have no idea what they're actually doing with their devices, and that's on us developers. It's our job to tailor systems to users by serving them with our knowledge, not confusing them with it. I doubt anyone wants to mess with the ECU settings on their car's dashboard - they just want to press the gas pedal, because that actually makes sense.
