This entire post will age poorly if we ever transition out of this incredibly self-indulgent and wasteful period of human civilization.
We should have walkable neighborhoods, mass transit of gleaming efficiency, bike lanes as priority, we should be encouraging socializing and creating spaces for people to gather that aren't profit-driven, but with plans to create comfort and recreation to better the people and foster a sense of belonging to a community. It's absurd we all live in places with lots of people but have no sense of belonging to a community. This goes against literally millions of years of our own evolutionary history. We NEED community to function and have healthy minds.
I mean, it's not likely to happen. But maybe when the next great apocalyptic event happens the survivors can try to remake things with a little more planning. After the whole period of darkness and cannibalism of course.
