One billion homes. To put a dent in the global housing crisis, we need to build one billion homes in a lifetime and today we simply aren’t solving the problem fast enough. To build the future, we must change the way we design and build for a world that will enhance human happiness and flourishing. The future starts with 3D printing. The technology that can create a more sustainable and beautiful world will be the same technology that helps us become a spacefaring civilization.  Will cities of the future be built by robots and drones? Will humans colonize the Moon and Mars? In this SXSW Session, ICON’s Jason Ballard  discusses humanity’s future and how architecture, design, robotics and sustainability can be in service to humanity and help us reimagine worlds.
