Since ancient times, humans have been obsessed with predicting the future, and artificial intelligence spawned by ant colony algorithms has made Laplace‘s demon-like precise predictions possible. In the future, vertical farming will be able to bring the growth of all crops under algorithmic control, predicting every second of a plant‘s respiration. The story describes an artificial intelligence drone caring for the growth of sugarcane, its duty is to eliminate all accidental factors and nurture plant growth, even though humans have long been extinct. At this moment, the appearance of an ant suddenly reminds the drone of its first patrol, in an era after the collapse of collectivism in the 20th century, a sugar mill destroyed by globalized precise predictive behavior...
