So this guy chooses to be a distracted idiot and let his phone or watch constantly tap him on the shoulder, as he admits it mostly nonsense notifications. I have a “smartphone” but I only check it if I get a phone call or a text message. But there are times I won’t even take the call or hear the message (such as in church, when it is on ‘silent’).
I remember the advent of Bluetooth, when rude people could be standing talking to you, and get a phone call and begin talking to the caller, without even so much as an “excuse me, I have a phone call”. Technology doesn’t make people rude, that’s a choice they make.
Technology makes their pre-existing rudeness more convenient.
Years ago I decided to mute all cell phone sounds. I determine when to do phone calls, when to check email, and when to text. I don't allow inanimate devices to interrupt me (unless expecting an important call - still my decision).
It's much easier to remain in the moment (in other words, in life).
Multi-tasking is not productive. I've spent my entire life practicing focus.
