The document summarizes Tony Hsieh's Downtown Project which aims to revitalize downtown Las Vegas through increasing density, collisions, and community. The $350 million project focuses on small businesses, tech startups, education and arts to attract residents and visitors downtown, with the goal of making it the most community-focused large city through co-learning and collisions. The hope is this will accelerate innovation, productivity and happiness by focusing on long-term return on community rather than short-term financial returns.
