I turn my notifications off, and I never let an application notify me unless there’s a problem with the computer. I have yet to receive a message so urgent it changed my life when I ignored it. Or, if it did, I long ago forgot which is the same thing.
What is urgent to the sender may not be urgent to the rest of us.
This may seem anti-social to many, but our lives have too much value to allow an algorithm to distract us.
