> it was another source of confusion. "What does the menu button do? How is that impossible to explain? > I know for a fact my mom didn't even know her phone had a trackball on it (hiya Android 2.x era), but she was mystified when I told her what it was and what it did. And? You're just saying such things are impossible to explain for you, or impossible to explain to people you know. But consider how complex the world is. The alphabet has 26 letters, all of which are impossible to explain. We have complex books, simple books, some people even drive cars with all sorts of levers and buttons and many dozen street signs to learn. They earn instruments and raise children, all sorts of complicated stuff, but they can't learn what a button does? How about we simplify English, remove 95% of the words, because some people never use them?
