Billionaires Are Building Fascinating Cities of the Future

In what feels like a very mid-century optimism vibe, billionaires the world over are pioneering futuristic cities that combine forward-thinking technologies and social trends. The concepts might bring to mind terrifying Borg cubes for some of us (fair). But so long as residency in these self-contained high-density environments remains voluntary, the constructions would provide fascinating opportunities to test out new forms of governance, economy, and urban design, and could provide learnings that have applications from improved political representation to interplanetary colonization.
