communication norms of the future...

Our society is evolving into a strange socially awkward existence. I can see it in my own behaviors. I would much rather email or text message than have an actual conversation on the phone. It's not that I don't like to talk to people— it's that I don't like to initiate conversations in the real world. Don't ask me why, I don't know.
In this very coffee shop there are at least 20 people with their eyes glued to their computers. I am sitting here among all these interesting (and yes, real life) people— all of which I ignore because I would rather talk to my friends on messenger.
I have heard that there have been cases of people born without tonsils or wisdom teeth because they are no longer needed. It's a form of evolution. Is it possible that in the future there will be babies born without vocal cords for this very reason? Maybe the children of the future will also develop long fingers and highly toned thumb muscles to better operate these new forms of communication and entertainment. I suppose time can only tell...
