Social media might play a part but I'd argue it's not the biggest one. It's urban sprawl, car dependency and now remote work. People are being isolated in boxes out in the suburbs surrounded by no points of interest or areas to hang around.
The most important thing for socialization is to just have physical proximity to other people in shared spaces, be that a park, office, school, club, etc. If anything, social media is just enabling people to sit in their boxes longer while still getting some form of socialization.
