Open weights may lag frontier AI by 3–12 months, but still act as a sovereign fallback

The post argues that a long list of conditions would all need to hold for Roon’s pessimistic scenario to be true: small actors must be able to run frontier weights, compute must not be the bottleneck, there must be a hard takeoff, offense must dominate defense, closed AI must stop proliferation, centralized controllers must remain competent and benign, and governments must avoid nationalization.
The author says each individual piece is plausible, but the full conjunction is close to zero. Their conclusion is that open source / open weights will likely lag frontier systems by 3–12 months, yet still matter as a sovereign fallback that cannot be revoked by terms of service.
They frame open source as something like AI’s “second amendment”: the bigger worry is power concentration, not openness.
