But, check this out...
Everyone misses that. All you have to do is initiate the conversation.
A few days ago I had a 30 minute discussion with a random dude on Swedish death metal bands because he happened to be playing a song from a band I know while I walked past his house. I've been walking for 5 years and this hasn't happened once, so I had stop and say something.
Every time I take the 90min train ride into the city I usually end up talking to someone for most of the way. I'm not a good conversationalist either or some super extroverted person. I'm just bored sitting on the train, and other people are too (even if they are flipping through their twitter feed).
It's prime pickings to start conversations because everyone is so deprived of it.
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.
It's not like I touch my friends much when we're meeting up IRL anyway, and voice is more comfortable to me than being on video (or being visible irl), as I don't have to think about how I carry myself.
Tons of gamers do this and I don't think many of them are in the "lonely" camp. I'm not sure why voice channels haven't seen wider adoption outside of gaming.
When she finally decided to dump me, she did it by text, and refused to meet in person or even talk on the phone about it.
If you're going to make a hypothesis that A leads to B then you should at other countries that also have A (in this case, lots of smart phones and internet) and see if they also have B (in this case loneliness). That doesn't seem to be the case, certainly not anywhere near the rate in the US.
This basic practice refutes a really large percent of unfounded views, and so is really a good habit to get into when looking to explain things.
Edit: not that I'm against it. I've had a very friendly chat with people in a mechanic's waiting room. It's just vanishingly rare.
At least for me I find it a bit more difficult to approach someone if I think they’re listening to something or on a call.
There used to be a time when constantly looking at a smartphone was the odd one out. Now it's the reverse.
