Source refs: `video:predictive-history-zaer-mqe7tq@transcript:v1#seg-0027`; `video:predictive-history-zaer-mqe7tq@transcript:v1#seg-0028` - The mature urban form Jiang treats as civilizational death because money, atomization, low fertility, and outsourced labor replace village relationships. Source refs: `video:predictive-history-k-l9jbgo74@transcript:v1#seg-0022`; `video:predictive-history-k-l9jbgo74@transcript:v1#seg-0023` - model: Spengler is presented as arguing that civilizations have life cycles like people: village, town, city, megacity, then death at the height of civilization. Source refs: `video:predictive-history-k-l9jbgo74@transcript:v1#seg-0019`, `video:predictive-history-k-l9jbgo74@transcript:v1#seg-0020`, `video:predictive-history-k-l9jbgo74@transcript:v1#seg-0023` - diagnosis: External threats do not reliably unify late civilizations; Jiang says factions would align with outsiders or aliens to conquer rivals rather than cooperate.
