Peking University mathematician: AI's millennium-prize wins are 'harvesting,' not discovery

In an interview with 新智元, Peking University mathematician Li Xinyi argues OpenAI/Anthropic's claims of solving math conjectures are PR-driven 'trophy hunting': results get 'solved but never understood.' He reveals a postdoc's unpublished draft was nearly reproduced verbatim on arXiv after discussions with an early GPT-5.x build, and says an unsolved conjecture of his for 20 years fell instantly to an LLM using its proposer's old method—evidence AI is mining human knowledge, not creating. He estimates the Navier-Stokes effort burned $20M in tokens, enough to hire 100 top mathematicians for a year, and insists credit and funding must go to humans contributing understanding, echoing the open letter by 25 Fields medalists including Terence Tao.
