No one is forcing us to watch or be on social media 24/7 but many are. Is it contributing to today's problems? I don't know but my opinion is it can't help.
I was first exposed to 24/7 news during the first Gulf War. I was in high school and they set up a tv in the cafeteria and allowed "concerned" students to skip class and watch. I was 16 and something in the back of my head said, "this can't be good" (ref 24/7 immersion in a subject).
Fast forward 12 or so years. I'm living in SYR flying for a commuter and a girl I was dating showed me that social media site that came before Facebook, I think it was MySpace. Thinking back now the same voice in the back of my head said the same thing.
