Accusations have surfaced against the United States, alleging that it has embedded 'backdoors' in AI chips, enabling control over the devices through functions such as tracking and remote shutdown. This strategy is suspected to be a means of restricting chip exports to China. The US government has indicated that it may ease export controls for companies willing to cooperate in embedding these 'backdoors.' Amidst this controversy, NVIDIA's export of H20 chips to China has sparked concerns. The article raises questions regarding the safety, environmental sustainability, and technological advancement of the H20 chips, urging consumers to make informed choices. In response, NVIDIA categorically denies the existence of any 'backdoors' in its chips and underscores its commitment to cybersecurity. However, further evidence is required to substantiate these claims. The Cyberspace Administration of China has interviewed NVIDIA and requested supporting documentation to address these allegations.
