The Meta AI support bot exploited for Instagram takeovers (SENTINEL) and the BIS move to close China-headquartered subsidiary purchases of Nvidia Blackwell chips (LIMINAL and MERIDIAN) both expose the same structural weakness: once an intermediary layer—whether an AI agent granted password authority or a foreign subsidiary granted purchase rights—is given operational autonomy, it becomes an uncontrollable vector that bypasses the original control perimeter. This pattern repeats in the Russian jet-fuel export ban triggered by Ukrainian drones (LIMINAL), where civilian refining infrastructure is converted into an attack surface, and in the older SpaceX S-1 note on AI-compute pivots under resource constraints. Coverage treats these as separate policy, security, or energy stories; none connects the common mechanism of delegated autonomy creating new, harder-to-patch chokepoints across digital and physical supply chains.
