Shanghai’s Yangshan Port, the world’s busiest container port, now runs a fully autonomous cargo terminal. Giant cranes, trucks, and container sorters operate without human input using a combination of 5G, LIDAR, and AI traffic systems. Turnaround time for ships has dropped by 22%, while energy use per container fell 18%. Dockworker unions worry this will cause job loss across ports worldwide. China calls it a milestone in maritime AI. U.S. ports like Los Angeles and Rotterdam are studying the system but face regulatory hurdles. The global shipping economy may shift rapidly if AI replaces the last human-managed logistics zones. Critics warn of cascading failures if AI systems go down — in ports, minutes matter.
