Jensen Huang
Does restricting AI chip sales to China keep the US ahead?
Skeptical: China is compute-bottlenecked in the critical next few years, so denying chips buys the US a real lead.
No: China has abundant energy, 7nm capacity and ~50% of AI researchers; controls just cede the world market to a foreign tech stack.
Do TPUs and custom ASICs threaten Nvidia's position?
Two of the top-three models (Claude, Gemini) trained on TPU, that's a real signal.
Anthropic is effectively the only ASIC buyer; CUDA, install base and best-in-class TCO keep the moat.
Is China memory-bandwidth bottlenecked (HBM2 vs latest HBM)?
Yes, roughly an order-of-magnitude memory-bandwidth gap matters for training and inference.
No, gang chips together with silicon photonics, NVL-style, and the gap stops mattering.
