He Quit Baidu. But First He Had to Build an AI Version of Himself
Before leaving Baidu, algorithm engineer Wei Ying created an AI version of himself to facilitate a smooth transition. This trend, known as 'zhengliu' or 'distillation,' is becoming common in Chinese companies as employees are encouraged to document their workflows for AI systems. While some see it as a way to preserve knowledge, others worry about being replaced by their own digital counterparts.
