Life happens. Your wife falls and breaks her wrist. Your mom has a heart attack. They want you now, not when you deign to look at your communications. And until you do look, you won't know if it's that she broke her wrist or that she had a heart attack.

If you are disconnected enough from other people that nobody has a valid demand on your attention, then you're part of the problem of social disconnection.
