Dan Wang, a technology analyst who lived in China for years, offers a firsthand account of the country's rapid development that goes beyond statistics to capture its human texture. Wang argues that China functions as an 'engineering state,' one that prioritizes building and making in ways that America, which has become what he calls a 'lawyerly society,' no longer does. The contrast is not simply about manufacturing capacity but about fundamental attitudes toward change: China's leadership reflexively asks how to build things, while America's reflexively asks how to prevent harms. Wang draws on extensive travel throughout China and conversations with workers, engineers, and officials at all levels. He documents both achievements and costs, describing the pollution, displacement, and labor exploitation that accompanied breakneck development. The book is neither a celebration of Chinese authoritarianism nor a warning about its rise, but an attempt to understand the country on its own terms. Wang writes with journalistic immediacy and analytical depth, offering readers a ground-level view of a transformation that will shape the twenty-first century. This is essential reading for anyone seeking to understand what China has become and where it might be heading.
