携程梁建章×罗永浩！在企业家与学者之间，他选择了最艰难的“往返票”

A boy who taught himself to code before most of his peers learned algebra. A Stanford-trained economist. The founder who turned a Shanghai startup into Trip.com Group — one of the largest online travel empires in the world. And, in recent years, the scholar China's internet teasingly calls "Director of the Birth Promotion Office," for his tireless alarms about the country's looming demographic cliff. James Liang (梁建章) has never fit inside a single frame. The businessman, the academic, the technologist, the public intellectual — each label is true, none of them complete. What looks from the outside like restless reinvention is, up close, a single continuous line: a lifelong preoccupation with innovation, with the long horizon, with what the future owes the present. To move between building a company and building a body of research is, as he puts it, the hardest kind of round-trip ticket to hold. Most people pick a destination. He keeps going back and forth — and brings something new home each time. In this twenty-fifth episode of Crossroads with Luo Yonghao, we sit down with James Liang for a three-plus-hour conversation that is not, in the end, about chasing the next market wave. It is about the ethics of technology, the higher orders of love, and what kind of future is still worth fighting for.
