In “The Three-Arched Bridge,” the novelist Ismail Kadare tells the story of a bridge being built in medieval Arberia (modern-day Albania, Kadare’s homeland) just as the Byzantine Empire is giving way to the Ottomans. The bridge is exceedingly difficult to build and equally difficult to cross. With every week bringing new headlines about the fierce rivalry between American and Chinese artificial intelligence developers, Kadare’s bridge is an apt metaphor for today’s global AI governance. In the US, policymakers are obsessed with weaponizing their country’s AI advantages.
