Probably what we will end up with is school from home, work from home, everything from home. Socialisation will move entirely online where you meet up on VR Chat or whatever is popular at the time. Many people will almost never leave their house.
This is... demonstrably untrue? People who work from home generally aren't house-bound, they will still go to the coffee shop, the local park, local stores, meetups, pubs, bars, etc.
Sure, if you live in a very amenity-poor area WFH may in fact be quite isolating - but if anything that reinforces the main thrust of the argument: live in a city where there are things to do other than working and hanging out with coworkers!
