You can not overstate the impact of the smart phone on our society. One thing I often think about is how people never just sit and think anymore, ever. The few minutes you have before class, waiting for the bus, during commercials, endless moments of downtime thru the day...Now every second of those moments is spent on the smart phone.
And I do believe that in a couple more decades, almost all communication will be in text form. I am pretty sure I could offer $100 to the first of my young staff to CALL me to discuss something, and none of them would do it. When these people grow up and are in charge more, it will become more and more prevalent and calling someone will be viewed like we view someone using a fax machine or pager. Any work that can be done remotely will be, doing something in person when not needed will be seen as a complete waste of resources.
And I am not necessarily being one of those that screams how terrible this all is. It is hard for me to accept, but I recognize that these things happen and what is normal to me will not be normal to my kids. That doesn't make them terrible heartless people that are getting it all wrong.
