The book explains why China leads in apps like mobile payments now, unlike the US which stuck with credit cards for too long. Lee argues this happens because China has huge amounts of real-time data from daily life that AI needs to learn quickly. While the US focuses on basic research in labs, Chinese companies use data from ride-hailing and delivery apps to test new features fast. This means Chinese tools solve real problems better because they are built on actual user habits rather than just theory. The author also notes that government support helps these companies scale faster than US firms can in a slower, more fragmented market system.
