Lucas and Luna explore a massive but rarely discussed trend: Big Tech's acquisition of submarine cable systems and the physical internet infrastructure that connects data centers. With cloud growth and AI workloads demanding more bandwidth, companies like Google, Microsoft, Amazon, and Meta have gone from leasing fiber to owning entire cable projects. The episode zooms in on Google's 29 submarine cables—including the $300 million Firmina cable connecting the US to Argentina—and what this means for network neutrality, cost control, and geopolitical leverage. Lucas breaks down how owning the physical layer gives these companies an edge in latency, reliability, and negotiating power with traditional telecom carriers. Luna questions whether this vertical integration could create new bottlenecks or undermine open internet principles. Tying back to recent stock moves (Microsoft up 0.7%, Meta down 1.6%), the hosts ask: as Big Tech owns more of the pipes, who gets squeezed? A timely look behind the submarine maps.
