We are more and more becoming a connected world, but it is in stark contrast to historical sense of what being connected was. As a society we will go through growing pains, but we will endure and redefine what it means to be connected. We once lived in an area our whole lives with barely interaction with people just 100 miles away, but now we live in a world where physical distance is not essential to engagement. As technology evolves so too will society. I watch now as VR is starting to have that effect, and while today we may view phones and SMS as ancient we will have advances that will make today's world seem ancient.
Humanity will learn and adapt and stumble but in the end we will evolve and redefine what it is to be connected.
I think you are right but we also must not lose sight of what it is that seems to make us human. It's the care and kindness we show towards other, the social interaction IRL not online that seems to be the most meaningful. Things we no longer seem to appreciate may be much more important than we give them credit for.
