The turning point of the labor force population lags behind the turning point of the birth rate. Japan's labor force population began to decline rapidly around 1995. China's decline started around 2015 and is expected to accelerate around 2030. The sign is that a large number of people born in the 1960s are starting to exit the labor market, leading to a shortage of workers such as wall tilers, cleaning ladies, and road maintenance workers, making it difficult to sustain large-scale infrastructure maintenance. Humanoid robots and industrial robots will be pushed to a very high strategic position to cope with the population decline. This is the fundamental logic of investing in computing power and motors; if we don't produce results in five to ten years, we won't be able to cope with the accelerated decline of the labor population.
