“The US action takes advantage of a decade-long boom in artificial intelligence in which new breakthroughs have become coupled to advances in computing power. Pioneering new projects often involve machine learning algorithms trained on supercomputers with hundreds or thousands of graphics processing units (GPUs), chips originally designed for gaming but also ideal for running the necessary mathematical operations. That leaves China’s AI ambitions heavily dependent on US silicon.” Wired on the heart of the American cold war with China. US Chip Sanctions ‘Kneecap’ China’s Tech Industry.
