I’m sorry, but this phrase has worn out its welcome.
Seems like a perfectly fine phrase to me.
Think of a city as both a spatial and a temporal grouping of people that are in the same place at the same time. Every hour a person spends at home on social media is an hour that they aren't really in the city and are not available for you to socialize with.
The cumulative hours that people spend staring at their phones are effectively a massive loss of population density. That lost density makes it harder to find people even if you yourself are getting off a screen and looking for them.
My thoughts on this are you need to have multiple roots into your community. This is something that you go to often and talk to people, become a regular, say hi. Think back to how your parents or grandparents did it: They went to church/temple/synagogue, they went to PTA meetings, they talked to their neighbors, they were in clubs, they went to the same bar.
So I think doing things that get you out of the house, consistently the most important part:
1. People need to make a point to talk to their neighbors, invite them over for dinner or bbqs, make small talk. How towns are constructed now is a hindrance to this (unwalkable towns where all of the houses are big garages in the front and no porches).
2. Join a religious organization. Go to church, but also join the mens/womens group, join a bible studies class. Attend every week.
3. Join social clubs / ethnic organization. The polish or ukrainian clubs, knights of columbus, elks, freemasons. Go every week.
4. Join a club / league. Chess club, bowling league, softball league, golf league. Tech meetups, DnD Night etc. But you have to talk with people and try to elevate things to friendships.
5. Have lunch, happy hour, etc with coworkers.
BYD Dolphin is right on the edge of being a CUV. They can trivially scale it up a bit. It'll be more expensive, but not by much.
At the very least, a general strike. That's absolutely the bare minimum that should be expected of the 94% of US citizens that do not support this regime (as is the claim upthread).
