Yang Zhilin, the 34-year-old Chinese entrepreneur rocking the AI world to its foundations, is often described as "baby-faced". It is not his only homage to prog-rock, as Yang suggested to one Chinese technology journalist two years ago. "We may be the earliest to explore the dark side of the Moon," he said of its AI technology. In one rare video of the technology entrepreneur, addressing a conference for chipmaker Nvidia. If Yang speaks his mind, he could be cast out like Jack Ma, the founder of Alibaba, who was barely seen for three years after a 2020 speech criticising China's financial regulations.
