The whole push notification issue needs to be seen in context though even though most people consider it in a rather myopic and self-centered manner. Push notifications, in and of themselves are not all that bad of a thing; but push notifications sent by all the apps and all the services without any sort of coordination is bad for all of the apps because people tune them out or turn them off except for the most important ones like email, messages, calls.

I think the OS that can solve the mental load question regarding notifications will make significant headway. I'm not sure what the answer totally looks like, but it seems to be it really needs to be an OS managed service. I would love to see it even utilize behavioral patterns, but I think there is still much work to be done for that to be useful, but I think Apple and Microsoft could be heading that way.
