Current interfaces are not aimed at being optimally useful. Padding everywhere as of today means more time scrolling and wasted screen space. Animations everywhere means a lot of wasted time watching pixels moving instead of the computer/phone giving us control immediately after it did the thing we (maybe) asked for. Hiding scrollbars is a nightmare in general in desktop OSes but is the default (once lost half an hour setting up a proxy because the "save" button was hidden behind a scrollbar).

Usability feels it has only been down since Windows 7. (on another hand, Windows has plenty of accessibility features that help a lot in restoring usability)
