Yes it should, but modernity also made us less reliant on the group and I think it made use more introvert and more social risk averse. This is something that can be worked on with reasonable cost.
Human experience isn't just hanging out with other people. It includes going to other places, experiencing what the world has to offer. You can't do much of that, if any, when you're living paycheck to paycheck like most people.
I think this varies from place to place. In some places, I've definitely felt like going out and interacting with physical people was too dangerous, since the culture was along the lines of "everyone for themselves" and "don't trust anyone". That being said, I've also lived in places where the people around me were extremely friendly, so for many people that opportunity still does exist.
For the people who feel like going out and interacting with strangers is dangerous, I think it might help to go to specific places where the kinds of people you want to meet would also go to (and the kinds of people you want to avoid wouldn't go to), although that can be hard to find.
