I can't imagine going to a general "group social event" like a party and making a connection. I'd end up just sitting there being bored until I left. I don't have the personality to just strike up a conversation about nothing with some one I don't know. But I do somewhat often go to events that revolve around my hobbies. There, I already have a connection with the strangers, through the hobby, and I have something to talk about or listen to. I've met plenty of new friends that way.
I'm old enough to remember what socialization was like pre-Internet. And by curated social media standards, it was really boring. It was also great.
It's fine to feel intimidated or shy, but then find something else that does feel manageable. It's something you can get better with by practicing. And I say that as an introvert who went semi-feral after Covid lol.
People sitting at home living on apps and watching TV who decide to go to a new group social event to change things up will struggle to make a connection with someone else who was at home on an app and watching TV deciding to get out and meet someone else.
The people who have friends.. already have friends. Those who don't are numerous social cycle iterations in on that.
And how long before those people just end up talking about TV shows anyway?
