How Did Humans Forget Technology Their Ancestors Already Knew?

Imagine every engineer on Earth waking up with total amnesia. The phones still work, the cars still run but nobody remembers how any of it was built. How long before your world falls apart? This isn't a thought experiment. It already happened. Again and again. In this ancient history documentary, we investigate Rome's self-healing concrete lost for a thousand years the Antikythera mechanism's thirty gears, Damascus steel no modern smith can recreate, and the secret of Greek fire. Plus the Bronze Age collapse, when broken trade networks erased whole crafts. From Tasmania's forgotten fishermen to anthropologist Joseph Henrich's discovery: technology lives in people, not things.
