China’s population projections:

2030: China has about 1.4 billion people; there are many people, but aging begins;
2060: China has about 1 billion people, entering deep aging;
2100: China has around 600 million people, entering an AI society;
2200: China may have around 200 million people, but productivity could far exceed today.
In the future, measuring national strength may shift from “how many people” to “how many high-intelligence people + how much AI productivity.”
This could be the first time in human history that: population decline doesn’t necessarily mean civilizational decline.
