Zero is no longer a technical target. It’s a moral one. This chapter shifts the lens from companies to communities, asking the daring question: can we design a society with zero inequality, zero crime, zero hunger, zero poverty, and zero prejudice? The answer, says Singh, is yes—if we fuse technology, empathy, and policy into bold new systems. From Copenhagen’s carbon–neutral blueprint to Amsterdam’s circular economy to India’s digital public infrastructure, the case studies are powerful and urgent. Whether it’s zero homelessness through housing innovation or zero discrimination via inclusive hiring, the goal is not utopia—but intentional design. Society 5.0 isn’t a fantasy. It’s a framework. And zero is its organizing principle.
