Episode notes
Selling Some Nvidia Chips May Preserve Taiwan Deterrence
- John argues chip bans can weaken a key deterrent by reducing China’s dependence on a functioning TSMC fab in Taiwan.
- He says if China cannot access TSMC chips anyway, invading Taiwan becomes less risky despite America wanting more AI chips domestically.
China Chip Controls Matter Through Demand Not Capital
- John says restrictions may slow China only if they suppress real customer demand, not just by denying government funding.
- Without buyers, local fabs miss the execution pressure and process excellence that come from running an actual business.
Cerebras Says Interconnects Break Giant Inference Clusters
- Cerebras CEO Andrew Feldman claims Nvidia’s new inference approach inherits a scaling bottleneck from wiring together thousands of smaller chips.
- He argues wafer-scale systems avoid interconnect latency and overhead, enabling much higher token throughput on giant models.
