Emile Riachi on dispute resolution, the art of travel, and political change in Lebanon

Tapa Ghosh on AI chips, studying your field, and collective self-belief

Jeson and I interview Tapa Ghosh [https://x.com/semiDL], an engineer, Thiel Fellow, and the founder of Volantis Semi, which raised $5M from Open AI’s Sam Altman to build photonic motherboards for AI chips. Tapa's journey began with crashed drones, leading him to a hardware deep dive and giving a talk Stanford on designing 3D ICs for deep learning as a teenager. We explore Volantis's approach to solving a key bottleneck in AI: latency and bandwidth in communication between chips. Tapa explains why using light instead of electricity could revolutionize AI infrastructure, and offers insights into the current landscape dominated by NVIDIA. His perspectives on self-learning, team building, and resurfacing old ideas to solve new problems reveal what it’s like to work on the foundational layer to our AI future. Please enjoy this wide-ranging conversation with Tapa Ghosh.
