South Korean TFR falls to 0.79, which is probably the lowest in the world. If historical association is of any indication, China lags South Korea about ~5-10 years in terms of TFR. This is the future of the East Asia, if drastic steps are not taken to reverse the TFR decline. For comparison, North Korea TFR is 1.9, indicating that this is not as much about East Asian culture, as it is about the highly materialistic hybrid of East Asian and Western culture that prevails across much of East Asia.
This is a historic moment and opportunity. The near term fate of East Asia will be determined by the strength and courage of its leadership to explore alternate solutions, separate from the West's largely absurd proposals of feminism being the solution (because we all just know feminists would love to have more children, but for the patriarchy) or immigration being the solution (because getting third rate immigrants that the US doesn't want is an obvious recipe for success, I'm sure).
The price is high, but so is the reward.
Succeed, and the country in question will likely become the model for other East Asian countries, if not the developed world as a whole. Solving TFR and achieving sustainable growth is the holy grail of post-industrial economic leadership. If a government wants to show to the world that it's got the superior system,
this is one way you do it.
Fail, and a long period of economic stagnation and decline awaits; for though automation and AI can provide a degree of relief, there is no fundamental advantage that East Asian economies enjoy beyond their superior talent base and forward planning. Robot factories and AI systems can be replicated else where, and they only address labor, not demand, therefore being vulnerable to economic nationalism from importing countries.
By contrast, demographic advantages other countries enjoy cannot be replicated in East Asia. If you don't have young people, you don't have young people, and it's young people who tend to take risks, create start ups, new business strategies, products, and inventions. AI might be able to help with many of these tasks, but they cannot replace the energy of human youths. We see a great example of this in the decline of Japan as a post-industrial power - they are just too old, too slow, to keep up with the pace of change in business and technology. China must not suffer the same fate.
