That's the thing: the HN crowd is a small segment of their user base. For most people, Cmd-P might as well be C-x M-c M-butterfly. The touch bar doesn't replace the function keys but rather the mouse.
Hmm, there's a touch of contempt for the average user in what you say... something that causes this current trend towards over-simplification.
Users love clear, systematic, repeatable, stable. Anyone using a shortcut often enough, given enough time will learn to use it because anyone can appreciate the advantage.
People that hunt-and-peck, or click around like seniors in a retirement-home absolutely hate the hostile and cumbersome UI that is hiding all the usefulness behind gimmicks.
It's not like I said they were "click[ing] around like seniors in a retirement-home". ;)
IMHO, users don't care about simple, clear, systematic, or repeatable, either; only stable. But keeping said workflow stable doesn't matter when your boss' bonus depends on how much innovation he fostered.
