The AI Hardware Stack Is Being Rebuilt From the Wafer Up

The AI Hardware Stack Is Being Rebuilt From the Wafer Up Before a single H100 ever runs a training job, it has to survive one of the most constrained supply chains in industrial history. Every serious AI accelerator, H100, B200, Cerebras WSE-3, starts its life on a TSMC wafer, gets etched by an ASML EUV machine, and then waits in a queue for CoWoS packaging capacity that is sold out through 2026. Understanding that stack matters if you are building on top of it, because the constraints at the...
