Back in 2013: My AI Only Reports Errors

In 2026, on the day that AI data engineer Zhou Heng was laid off, he saw with his own eyes that a piece of erroneous data caused an accident. When he opened his eyes again, he returned to 2013. In front of him was a data labeling company whose boss had escaped, twenty-three employees who were owed wages, and an old computer that had followed him back. The future AI in the computer will not write code, will not recommend stocks, and will never give correct answers - it will only tell Zhou Heng: The batch of data in front of him will cause the most expensive mistake in the future. While others were chasing smarter models, Zhou Heng led 23 ordinary people to build the most inconspicuous and indispensable foundation for artificial intelligence, starting from correcting the first mistake.
