Recently, the question of whether the H20 chip harbors a 'backdoor' has ignited widespread debate. Experts have emphasized that it is technically feasible to embed functionalities like 'tracking and location' and 'remote shutdown' within such chips. A deeper probe unearths that the United States has systematically contemplated installing 'backdoors' in AI chips. The US government has gone so far as to propose that companies cooperating in the installation of such 'backdoors' would be exempt from export control restrictions, potentially even enjoying relaxed export controls for 'low-risk Chinese customers.' Against this backdrop, NVIDIA's approval to export H20 chips to China has sparked profound concerns.
