But China is already in decline before reaching this ascendancy.

I think new models will result in new structures, not just a switch from the US to China.

China's population is declining while building and operating the largest fleet of manufacturing robotics in the world. The US population is not declining as quickly while having limited capability to do anything. A recent example is $500M of taxpayer dollars spent on a munition manufacturing facility that did not build a single munition.

The US has coasted just about as far as it can go on it's exorbitant privilege while failing to invest in the future.

TLDR China builds, and will continue to build long into the future, the US prospers (for now) from financialization but cannot build, nor has the will to attempt to.

> Frankfurt, May 05, 2026 — China has launched its 15th Five-Year Plan by placing robotics at the heart of its modern industrial system. The aim is to pivot its AI research towards physical applications with robots as main drivers for economic growth. This is a next step in the country´s strong automation development: China´s manufacturing industry already has an operational stock of around 2 million units — approximately 4.5 times more than the global no. 2, Japan. 54% of annual industrial robots installed worldwide were deployed in China. This is according to the World Robotics 2025 Report, presented by the International Federation of Robotics (IFR).
