Idk how old your mother is but my dad is 80 (I’m 53) and he doesn’t understand windowing at all. I always thought it strange he has never figured it out. Even phone UIs baffle him. Older generations inability to grasp the concepts behind computer interfaces seems so strange to me. I wonder if a command line interface would make more sense. I know that sounds crazy, but using bash, for example, is more straightforward, in a way. You can list what folder you’re in, execute commands without any images or windows or other distractions. Mainly, it’s memorisation, as opposed to the more abstract concepts behind desktop interfaces. Sorry, I’m rambling now lol.
