           | 
           | I feel like there's a little disconnect between these two
           | statements. It's not that television is taking priority, it's
           | that the times when people used to break out a book -- that
           | they carried in their back pocket or purse! -- now break out
           | their phones and engage with social media, or they check
           | their work email, or respond to slack messages, or they get
           | involved in texting, or they play some video game just to
           | make the time go faster. I suppose some of them put in
           | headphones and watch Netflix, but I don't see that often, to
           | be honest.
           | 
           | The world has gotten so busy and defaulting to 'on' that no
           | one feels they can default to reading a book, _but you can_.
           | You just have to decide to carry a book and, instead of
           | breaking out a phone at those times to stay connected, you
           | _just let yourself be disconnected_ , and you read a book. Or
           | meditate.
           | 
           | That's how I go about my life, and frankly I don't understand
           | why more people don't. I never use my phone unless it's an
           | emergency. I get a lot more out of life meditating and
           | reading books than checking my email, playing candy crush,

         | I agree with this to a point. A lot of this happens online
         | first, and companies will do whatever they can to align
         | themselves with what's popular online at the time. These
         | companies align to whatever the most virtuous opinion is at the

         | companies can almost be viewed as a microcosm of society as a
         | whole. None of their alignments are real. Maybe that's why you
