I'm curious if this is a direct result of the internet and smartphones. The two make us feel more connected, more global, but I think it makes us more isolated. I miss talking to my friends on the phone, and hanging out in the 90s. Everything, especially how humans interact, is so digital today.
My wife and I had this discussion the other day. Messaging or posting on FB or whatever is very flat. There's no depth to it at all. It doesn't replace hearing a loved one's voice or looking into their eyes or hugging them or even having a meal with them. When you go and you visit them and you see them, you realize how much you're missing and, yeah, it feels very isolating to realize that. Social media is a facade.
