Sorry for performing an /all driveby, but it's a wee bit ironic that the author uses the image of the Nakagin Capsule Tower in Tokyo—built in the early 70s and demolished last year—for a 'vision of the future arcologies.' Granted, it fit the architectural philosophy for density and practical use of space, but here we are 50 years later and, thankfully, self-contained working/living environments are not a thing.
I sincerely hope humans won't end up inhabiting Sim City 2000's Darco Arcology in the future.
