I just disable all notifications other than SMS and phone calls and life is good
And now the tables have turned, to put it mildly, and a lot of people are growing up with the tech and not enough people around them to point out all the experiences they're missing out on because they're servicing a notification manager.
Conversely, a lot of people who didn't really like computers ten years ago are now hopelessly addicted to their phones. So maybe its just more practice, and we can look forward to more people doing this as times goes on.
If successful phone-based VR takes off though, we're all screwed ;)
