Uruguay's "city of the future" joins list of billionaire utopias

Uruguay is set to host “+Colonia,” a new waterfront community billed as a “city of the future” focused on sustainability, technology and AI-led economic innovation. The project, announced this month by Praxis, will be built next to Colonia del Sacramento and aims to welcome residents in mid-2027. Praxis says it plans to mobilize $1 billion in investment over the next three years, describing the development as “the world’s first digital nation.” Supporters tout improved quality of life, while critics question whether an AI-driven model can function as a real city and whether the funding goals are realistic. The article also reviews other proposed billionaire “utopias,” including California Forever and Japan’s Woven City.
