1. Notifications on a watch do not need to be more disturbing. To the contrary, it is quite possible that the vibration on the wrist is easier to ignore than the phone, that it is easier to just check the display very shortly, instead of fumbling with the phone in your pocket. That was one of the reports from the android devices used. 2. There is no age of notifications. There is one system where notifications seems to go a bit rampant, and even on iOS user have the option to just not opt into them (like several others mentioned here already). 3. The great AI solution actually colides with the idea of seeing them as a feed, because there, the solution is rather to let the feed be filtered by humans. I don't let newspapers ping me, I follow friends who ping me with articles from newspapers. And there always where notification we let humans decide that we want to see them, they are called texts/sms/chat messages. A technical solution might be nice, but is probably not necessary - especially since it is so much easier to just not accept anything unimportant to send you a notification. 4. A really great notification concept is notify-osd on the ubuntu desktop. That concept behind the software defines notification as awareness things that users might want to see or might want to ignore, so they are in black boxes that can be transparent when the mouse hovers them, they are only shown shortly, they don't make a sound, they are not animated, they never expect any input. It's the perfect system for stuff that is not really important. If one really has to let every crappy app ping oneself, it should be with a notification system that adopts this principles.
