Not everyone has left the real world, only the people who got really sucked into the online/social media world. This can maybe seem like the whole world though, if you're in that bubble.

Bars are still packed on the weekends, people still gather at churches, or gyms, or bowling leagues, or book clubs, or any number of other "IRL" activities of all kinds that are going on. You do have to make the effort to go out and get involved though, nobody is going to come and rescue you.

Many of these activities have gotten extremely expensive or just died out in the majority of places. There's 2600 bowling alleys in the US compared to 4000 20 years ago. That's a decline of 35% without accounting for population. Last time I went to a bowling alley the price for a lane without drinks was 100 dollars for an hour and a half. This isn't even in a very high cost of living area. Besides a place like the gym can hardly be considered a place where people gather, most people just see it as something functional and would rather not be disturbed (I believe this has gotten 'worse').

I agree with the fact that it's exaggerated online but when you see these kinda numbers in the vast majority of activities which were affordable for most Americans not too long ago it's not solely to be blamed on individuals.

I believe in the majority of the country things will only get worse with how little value is placed on being involved in things for 'community'. People have gotten more anti-social because of social media (and just media in general).

Most tech workers won't be as impacted by this I assume, they can afford paying 200 dollars for bowling without thinking twice, same with many others of the upper middle class.
