> I would say information density was too high. All those always-on indicators: 3D scrollbars, buttons, etc. create a very busy picture.

Have you been in nature recently? We've evolved to deal with very busy pictures and parse relevant information from them.

New UIs often don't have relevant information - like what is clickable or scrollable - and that's a problem.

It used to be that grandpa couldn't find a button with his poor eyesight, since everything was cramped and too tiny on the small screens we used to have.

Nowadays the clickable label is hidden behind a tiny hamburger menu that you can't tell apart from a mere stylistic flourish on the massive screens we keep mostly empty. Now neither of us can find the button.

That's progress? Every time I open an old application I breathe a sigh of relief because I can feel the cognitive load decreasing. Not having to put myself in the headspace of the designer to figure out what random geometric shape happens to be interactive is like taking a vacation.
