Beijing Is Closing Its AI. Washington Should Open.

Stack wars are won by who ships, not who hoards. The operating-system, cloud, and software waves all broke the same way: the side that spread widest set the global default, and the side that walled itself off fed the other side's network.

AEI's recent op-ed reads Beijing's reported move to restrict exports of its most advanced AI models as a tell that China is choosing the closed-stack path. The American response should not be a mirror.

The historical pattern suggests a mechanism that tends to repeat: control of the layer where the world writes its defaults. Microsoft, Amazon, and the SaaS incumbents did not win on secrecy. They won because every developer, integrator, and IT department outside their walls had a reason to write to their layer. Restrict a frontier model and the customer writes to the next one. Export the full stack, as White House Executive Order 14320 and the April 2026 Federal Register consortia call are now attempting, and the default shifts the other way.

The H.R. 2683 Remote Access Security Act marks a counter-current: it would extend chip-era export controls into cloud-based AI services, the same layer where American advantages are most exportable. That is the move to watch, and the one the OS, cloud, and SaaS receipts warn against.

The stakes are not who has the best model this quarter. They are whose stack the world writes to for the next decade.
