It's a lovely set of sentiments. I think another aspect of UI that has been lost is discoverability - finding out how to do things in a new interface seems harder than it used to be when there was one app-level menu bar. Too many things are hidden in context menus, found only by right-clicking or long pressing on just the right spot. A set of multi-modal interfaces might just make discoverability even worse.

Consistent use of context menus would actually be a boon, because it’s a single mechanism that can be applied everywhere, and just opening a context menu is a benign interaction (no fear of triggering some undesired action). The disappearance of context menus is one thing that I lament about modern UIs (another is tooltips). There may be “share” or “ellipsis” or long-press menus, but they are highly inconsistent, and you never know where to look for desired or possible actions.

But don't you love buttons with ad-hoc icons and no text and no explanation of what they do and they don't even have any visual indication that they're buttons? :)

In the late 1990s and early 2000s, we used to call that "mystery meat navigation." Now, we call it user interface design.
