We largely abandoned an unbelievably efficient form of human input in favor of big fat dumb slow touchscreens. Can you imagine where we'd be as a species if we got our shit together 25 years ago and standardized a few of the most important keyboard shortcuts and layouts and that was the default everywhere? I won't advocate terminal-only, but even classical GUIs with windows and icons and all could have been much more efficient if keyboard input and navigation was given priority instead of the comedy of using a pixel-precise indirect pointer to fart around a virtual screen select some button when...there are buttons under my fingers.
