申请入围"中国IC独角兽" 半导体高质量发展创新成果征集 今天，黄仁勋在中国台湾地区Computex 2025的主题演讲结束后，接受了 Stratechery的主理人 Ben Thompson的 一次面对面访谈。 在这次访谈中，黄仁勋比较罕见地对AI扩散规则、芯片出口管制、美国对华AI竞争的战略 等问题发表了观点。 黄仁勋认为，AI扩散规则限制其他国家使用美国技术，这个目标从一开始就错了。美国应该加速向全球推广 美国技术，否则一切都为时已晚。如果目标是让美国处于领先位置，那么AI扩散规则完全是反作用。美国公 司不能放弃中国， 如果不去中国竞争，就会允许中国生态系统在美国公司缺席的情况下发展壮大。这将导致 新平台出现，但这些平台将不是美国的。尤其在AI技术迅速向全球扩散的时候，中国的领先地位及其技术将 扩散到世界各地。 在黄仁勋看来， 美国要想赢得和中国的竞争，不能靠 打压竞争对手，而是要靠快速发展和创新。因为美国商 务部 禁止H20对华出口，英伟达 不仅损失了55亿美元（库存注销），还放弃了中国市场150亿美元的销售收 入，美国政府也损失了大约30亿美元的税收，且还威胁到CUDA平台。 任何认为仅仅通过禁止向 ...
