Its funny you mention watches. Another reason I rarely use the SE is because all of my notifications, volume control, etc are on my Pebble.

With this, I think you're onto something. So long as what I see isn't uploaded anywhere, I can't wait for AR glasses. I'm horrible with names, so some form of [completely invasive] facial scanning would be a god-send. And if not that, at least some sort of AR where I can slap a name tag on someone at a function.
