Nvidia’s chief security officer has published a blog post insisting that its GPUs “do not and should not have kill switches and backdoors.” It comes amid pressure from both sides of the Pacific, with some US lawmakers pushing Nvidia to grant the government backdoors to AI chips, while Chinese officials have alleged that they already exist. It’s an overreaction that would irreparably harm America’s economic and national security interests.”Both Nvidia and the US government would like the company to be the dominant supplier of AI chips to China, but the suggestion of direct US access to the hardware might put that at risk. Chinese chip companies are steadily improving their performance and production capacity, as China looks for a homegrown alternative. That raises the possibility that Nvidia will be usurped in the market by Huawei, a company that knows a thing or two about losing market share over alleged government access.
