Yes, I understand what you're getting at, but personally I've never felt nostalgic for 'the good old days'. On the contrary, I find having the random happenstance of geography determining 'here, these people are your friends' to be terribly limiting. I want to spend time and socialize with people because I find them interesting, because we enjoy similar things. They may live down the street, or on the other side of the world, I don;t care. Games we play and things we do may be facilitated by computers, game consoles or mobile phones, but that doesn't make them any less enjoyable.
Just today I was with my kid out on Pokemon Go Community Day, with dozens of other people from my town. Some I knew, some I didn't. We still had fun (got me three shiny Bagon!). In the last 4-5 years I went with my Ingress friends to Vienna, Munich, Ljubljana, Bratislava for weekend outings, usually with a busload of other players from my city to meet up and play with hundreds, sometimes thousands of other players.
It's not just games. I got my first Neil Young bootleg tapes from a guy in the US I knew only over a mailing list (that was some 20-odd years ago). I had a wonderful weekend in Budapest in 1996. with Sophie and her friends, who I knew only through Pearl Jam mailing list. Socialized with a granny from Lisbon. Portugal, who I never did meet or see, but regularly chatted and exchanged music for years through Soulseek, one of the early file sharing programs.
And here we are, too, on Cake. A bunch of people from all over the world. And still, I have a mental image and model for many of you here. You are becoming part of 'people in my life'. And if this weird and wonderful thing keeps going, I pretty sure some of you will count towards my Dunbar's number.
Times change, relationships change, socializing changes too. I say roll with it.
