I sorely miss the days when it was possible to explain to someone the principles of how an OS UI worked, and for those principles to be reusable across a wide array of applications. Today, every application seems to just do its own thing, and continually churns its own UI, chasing trends. There was a time when an elderly relative would say “computers are too hard to use”, and I could recommend a book or manual that would help make it clearer. Nowadays I tend to just agree with them.
