> In what universe is anyone proposing tearing down the buildings in NY, London, Tokyo, or Shanghai and replacing them with SFH? COVID-19 will kill megacities. Whether they'll all be torn down and replaced with single-family dwellings or just left to rot into slums is indeterminate, but they're going to go away one way or the other. Cities over a certain size are only viable if they have an effective public transport network, and public transit isn't compatible with endemic COVID-19. Get one superspreader on one train car and you now have 250 infected people and multiple deaths. Even the vaccines that are currently under development would only reduce the carnage to 125, rather than 250, people. No one is going to accept this risk if they have a choice, which is why public transit ridership has cratered everywhere. Remove public transit from the picture and you have a car dependent city. By definition car dependent cities must have a low density to keep traffic congestion barely manageable. Highrise multifamily is no longer possible, nor are high rise offices. SFH with suburban office parks are the only style of building that makes sense when everyone must drive. Further, everyone who can is shifting to WFH, which will erode the importance of cities as a concept. Get good Internet into the rural areas and most white collar workers will live there just to reduce the risk of dying from COVID. When, in a few decades, we eventually get COVID-19 vaccines and treatments good enough to go back to the way things were, the changes to how we live will be socially baked-in and it will be too late to walk them back. Cities are over.
