In the near future, AI has not awakened, rebelled, or raised weapons against humans. It just becomes cheap enough, stable enough, and deep enough in the process. It first takes over a large number of jobs in the white-collar world, and then along the chain of profits, platforms, orders, finance, and finance, it pushes the entire human society to a doomsday without explosions. The crisis first broke out in the United States, and then spilled over to other parts of the world through global demand, platform systems, supply chains, and computing infrastructure. In China, the true face of this doomsday is most clearly shown in the cooling of external demand, white-collar replacement, platform involution, mortgage defense, and county financial losses. The world did not end immediately. The lights are still on, the subways are still running, and shopping malls are still open. However, the working society, the middle-class schedule, and the old order of "people are naturally at the center of the economy" have quietly ended.
