Just two example out of millions: Uber reduces the need to have friends drive you to the airport. ChatGPT reduces the need to ask your friends about their areas of expertise.
However, ALL the kids of that generation have none of that connection to each other. We would feel like we are imposing if we called a cousin’s friend in a different city to hang out or stay over. We prefer to stay in nice hotels, and fly to exotic destinations. And I don’t think we can re-create the type of relationships our parents had with their extended tribe, no matter what, since we are all very independent.
But look at how we have life set up in a US suburb, where all our travel is in an environment where we cannot talk to anyone, most of our commerce is done in places designed to get you in and out as fast as possible, and where employees rotate often enough it might not be all so easy to ever make them register as people, much less build relationships with you. Stopping anywhere is inconvenient enough that that few people spend a significant amount of time lounging anywhere other than their home. So where are you, exactly, supposed to make friends? You have to be trying pretty hard.
People's best bets is to pick up a hobby where people meet regularly, like an exercise class, or a boardgame meetup. Then you have enough people that the probabilities of finding someone compatible go up.
tl;dr friendship is formed when there is alignment of values/personality (but not in the way people always expect), and also when a lot of time it put in.
The time thing is powers of 10. IIRC, 10 hours to get to know someone as an acquittance, 100 hours is a casual friend, 1000 hours is a good friend, and 10,000 hours is a lifelong friend you can really depend on.
The way to fast track this process is to create a shared feeling of oppression. Military boot camps rely on this technique to rapidly form group bonds. It is the same idea behind quite a few team building outings as well. It is also why college dormmates can form long lasting relationships, lots of time spent together during a period of high stress.
Same goes for people working at high pressure startups together.
