Maybe we won't have cities? With automation, faster internet connections, online shopping, online learning, VR, and the recent surge in people working from home, I could see a future where cities become mostly obsolete.

Some functions in society would still need a central location, like hospitals, transportation hubs, tourist attractions and jobs that require people to show up in person, but I don't see these forming the foundation of something like New York City or London.

Most of them don't even have to be in a city. There's plenty of airports and large hospitals that are located in rural areas today, and a group of companies could easily buy up some land and build a small town/campus with apartments for their employees.
