The path to the post-Covid city

The basic exchange that’s required is obvious: cities need to take space from cars, offices and shops and give it to affordable housing, community and nature. The city of the future may look a lot like the city of the past, just cleaner: bicycles, farms and 18th-century-style homeworking rather than flying cars. I’ve tried to distil the best ideas for the post-Covid city, focusing on rich-country megapolises such as London, New York and Paris. Developing-world cities have different problems, but much of what follows applies to them, too.
