Recently, Meta officially announced a major project named Project Waterworth. This initiative represents a multi-billion dollar investment spanning several years, aimed at constructing an undersea cable exceeding 50,000 kilometers to support global AI infrastructure. Once completed, this undersea cable project will become the longest in the world, capable of withstanding damage from ship anchors and other hazards. According to the project plan, the cable will extend from the East Coast of the United States to the West Coast, with depths reaching up to 7,000.
