Cory Gardner, former U.S. senator and current NCTA CEO who led on Taiwan and tech policy, discusses how AI depends on boring infrastructure like fiber, spectrum, and memory chips. He highlights DRAM shortages, local opposition to data centers, and how foreign influence could make Americans wary of AI. Short, policy-forward conversation about practical bottlenecks and geopolitical tech competition.

Harjot Gill, co-founder and CEO of CodeRabbit and serial entrepreneur in developer tooling and AI workflows. He talks about why code review became software's new bottleneck. He explains centralizing reviews as a guardrail for agent-driven code. He discusses scaling a freemium, viral GTM into enterprise and how AI reshapes junior engineer productivity.

Moritz Baier-Lentz, investor and founder in gaming and AI who helped build Goldman Sachs’s gaming practice and co-founded General Intuition. He argues video games are the ideal training data for future AI. He discusses play as core to learning. He outlines how game design, player-driven worlds, and social platforms shape next-gen AI and hit games.

Ronnie Chatterji, Chief Economist at OpenAI and former White House CHIPS coordinator, discusses how AI reshapes growth, jobs, and firms. He explains how people actually use ChatGPT and the shift from chatbots to agentic AI.
