Why It Matters

Data movement is a major bottleneck and energy drain in modern computing, consuming up to 50% of a data center's power, a market of over $200 billion annually. Mainstream adoption means processors can communicate at terabits per second with minimal power consumption, enabling far more powerful AI and scientific computing. Chip manufacturers like Intel and AMD would be major winners, while traditional electrical interconnect component suppliers might need to pivot their offerings. Key barriers include integrating lasers directly onto silicon reliably and ensuring cost-effective manufacturing at scale for complex chips. Widespread adoption for on-chip applications could be 5-10 years away, with the US, China, and EU racing for dominance in next-gen chip technology. A subtle consequence is the potential for entirely new chip architectures, moving away from von Neumann bottlenecks and enabling truly parallel processing.
