Comment by Felix Juefei Xu

Having worked both on AI safety topics—including robustness, evaluation, and responsible model development—and on frontier multimodal AI systems, I have seen firsthand how quickly capabilities can advance and how difficult it can be for our understanding, safeguards, and institutions to keep pace. I remain deeply optimistic about AI’s potential to accelerate science, creativity, and human progress, but realizing that potential requires more than advancing capabilities alone. We should also build credible technical and governance mechanisms that allow the international community to coordinate, assess emerging risks, and deliberately buy time when necessary. For these reasons, I support this statement in my personal capacity.
