On the 39th day of the rain, Haizhou No. 3 Tunnel received an unsourced early warning from a large city model "watching the tide" twelve minutes before water surged.
Developer Meng Heng illegally blocked the road and saved the people at the tunnel entrance. It also made the whole city start to ask: Why did a model with no explanation of the basis know about the disaster earlier than all the sensors?
Meteorologist Qiao Zhao found in the raindrop data that tide watching did not predict the future.
It is a retelling of another disaster that has already occurred.
Early warning can save lives, and it can also determine who gets roads, medicines, beds and the right to leave first. When the city hands tomorrow over to algorithms, Meng Heng and Qiao Zhao must answer first: Who is using early warning to rewrite everyone's future?
