The global economy relies on a network of undersea cables transmitting trillions of dollars in transactions daily. Many of these cables are exposed and physically vulnerable to sabotage, representing a critical, often overlooked, national security threat with massive economic implications.

The funding model for undersea cables has shifted from state-owned telecom consortiums to private investment, and now to big tech. Giants like Google, Meta, Amazon, and Microsoft now fund and own two-thirds of all new cables, giving them unprecedented control over the internet's physical infrastructure.

Contrary to fears of digital takeover, the US submarine-launched ballistic missile system is deliberately analog. Its primary navigation method is "star sighting"—an ancient technique—making it resilient to hacking and external digital control, a fusion of primitive and advanced technology for ultimate security.

With roughly 100 undersea cables cut accidentally each year, the internet remains stable due to immense redundancy. This is achieved through a form of 'coopetition,' where rivals like Google and Meta will purchase backup capacity on each other's proprietary cables to ensure their own services never go down.

The quest for nanosecond advantages is a physical battle over geography. It began with co-locating servers in data centers, escalated to digging dedicated, straighter fiber optic cables from Chicago to New Jersey, and culminated in building microwave tower networks for even faster, line-of-sight data transmission.

The primary bottleneck for Project Maven wasn't algorithms but outdated digital infrastructure. Data packets crisscrossing the Atlantic multiple times and physical hardware encryptors creating bottlenecks revealed that cutting-edge AI is useless without a modernized, high-throughput network to support it.

Due to inertia and the high cost of building new landing infrastructure, today's fiber optic cables often terminate in the exact same coastal cities as telegraph cables did over a century ago. This historical path dependency creates concentrated points of failure instead of a more distributed, resilient network.

Just like global shipping, the internet's physical infrastructure is concentrated in geographic chokepoints. The Red Sea and the Strait of Hormuz are critical corridors for data traffic between Asia and Europe, making them highly vulnerable to disruption by malicious actors.

Previous fears of a glut in undersea cable capacity have been erased by the rise of AI. The massive data flows required for training and operating AI models are accelerating the need for new, higher-capacity cables, driving the next major investment cycle in the industry.
