It is now essential to be considered part of the society, to the point that someone who does not want to or cannot carry a cell phone is sneered at. Anecdotally, I was in the USA and during a few day lay-over, I wanted to get a hair cut. I was refused service at a hair cutting chain because I did not have a cell phone with me (it was in the hotel, did not want spam, would not get there and back on time, etc.). I offered credit card or cash, but was rejected, and explicitly told I have to have cell phone.
I am not angry, just sad.
As @nonrandomstring noted, "absurdity of reality is escaping parody".
