The $475M Bet to Build 1,000x More Efficient Compute | Naveen Rao, Unconventional AI

Learn more about Unconventional AI at https://unconv.ai/ Unconventional AI founder Naveen Rao joins Lightspeed partner Guru Chahal to explain why the future of computing is running into an energy wall and why today’s chip architectures aren’t built for the AI era ahead. Naveen breaks down how deep neural networks are rapidly becoming the dominant global workload, why this shift is unprecedented, and why power efficiency is now the defining constraint for compute. Drawing on his background in semiconductors, neuroscience, and AI systems, Naveen explains how Unconventional AI is rethinking compute from first principles, using physics-inspired approaches rather than traditional digital abstractions. He and Guru discuss the limits of current accelerators, how far modern hardware is from biological efficiency, and what it takes to pursue a 1,000× improvement while still building something that can scale. It’s a grounded look at the AI energy crisis and what it will take to build the next foundation of intelligence.
