New cities should be able to leverage technology to create large buildings as public reconfigurable infrastructure. Especially if you think of them as megastructures that are there to help provide infrastructure and shelter for smaller modular buildings inside. This makes it less likely to end up with a very large building that becomes unusable as society shifts. For existing cities, I wonder if its possible with at least some of these office buildings to change them to residential or mixed-use.
