The quantity of human interactions has increased, but the quality is arguably diminished.
When I was in high school I bought my first cell phone, and it came with a truly amazing feature: Text messaging. I remember how amazing it was to be able to communicate with anyone without actually talking to them!
Things got even better when I got access to the world wide web on my spare time. I found a chat room with some friendly people, bound together by a common interest in video games and pop culture, which I still hang out in every day, almost a decade later. Without that room and those dozen+ people I count among my friends, spread across time zones, I might have been a very lonely person.
The first time I learned about this was reading an article on, of all places, Cracked. I'm not allowed to share links yet, so if you have the time, visit Cracked and search for "monkeysphere". It's seriously one of the most eye-opening articles I've ever read.
