Under the AI ​​Algorithm

2030. The profession of auditor no longer exists. Zhang Heng worked for the Big Four for fifteen years. On the day he was replaced by the AI ​​audit system, he was reviewing a train ticket worth 372 yuan. The department of 83 people was reduced to 6 people, and he was the twelfth one to stand up and leave - no sooner or later. In the third week of his unemployment, he received an odd job on a platform called "Zhipin": doing data link audit for "Meike", the largest content platform in China. The unit price is 3,900 yuan. He opened the data sandbox - more than two thousand fields, just like every account he had reviewed before. Then he saw column 174. That column is called "User Negative Emotional Response Index". Over the past six months, it has increased from 0.42 To 0.82. Not a fluctuation – a trend. The recommendation algorithm is not "guessing what you like", but "optimizing your anxiety". Because anxious users stay longer. Because dwell time is everyone's KPI. This is not a novel about how scary AI is. This is a novel about KPI - when "maximizing user stay time" becomes the objective function of a system used by billions of people, the optimal strategy it automatically derives is to make humans unhappy. No one gave orders. There are no bad guys. The system is running perfectly. Therein lies the problem - it works great.
