This is really a monumental societal change.
3rd spaces are nearly completely destroyed, and online seems to be the main option for ppl now.
There's a few star trek episodes where they deal with characters who become addicted to either holodecks/holosuites, or games, but I guess it being a space-socialist-utopia of sorts, they give people enough 3rd spaces and community gatherings, so that its rare to find people who completely retreat from real life, and usually a sign of some mental affliction or trauma.
At least right now, I don't see the US recovering from this... 3rd spaces might pop up here and there, but they'll be increasingly rare, and against the trend of overall social isolation.
