In 2019, Yang Zhilin completed his PhD at Carnegie Mellon in four years. Apple, Google, and Meta courted him; Stanford and MIT offered postdoc roles. He chose none, returning to China to found Moonshot AI. His supervisor Russ Salakhutdinov recalled Yang's conviction: starting his own company was a life goal, not a visa necessity.

Last week, Beijing-based Moonshot released Kimi K3, ranked alongside OpenAI and Anthropic flagships. Elon Musk called it "impressive work." Silicon Valley asks why America let him go, but immigration policy is only part of the story. Multiple Chinese founders cite larger home networks, familiar culture, unified regulation, and a deeper talent pool as advantages.

China has built its own pipeline. Stanford's Hoover Institution found 53.5 per cent of DeepSeek core researchers never studied abroad; 70 per cent with US experience returned. Meanwhile, a 2024 Stanford survey of 1,304 Chinese-descent scientists revealed 73 per cent felt unsafe, 65 per cent citing anti-Asian hate. The US visa system favors employment over entrepreneurship. As Yang Zhilin shows, returning is now a first choice — not a fallback — testing America's decades-old formula of attracting and keeping the world's brightest minds.
