Marc Andreessen on AI Winters and Agent Breakthroughs

Anish Acharya speaks with Peter Yang, creator and product lead at Roblox, about how personal AI agents are replacing the apps we open every day, why coding agents feel like slot machines, and what happens when the cost of building software drops to near zero. They discuss why future companies will stay radically small, how the IDE is becoming a thinking tool rather than a making tool, and why human ambition will always create more jobs than AI eliminates.

a16z's Ben Horowitz and Erik Torenberg speak with Alex Blania, cofounder and CEO of Tools for Humanity, World, and cofounder of Merge Labs. World is building the largest real human network, a proof-of-human layer for the AI era. They cover the technical challenge of proving human uniqueness at scale using iris biometrics, the privacy architecture behind World ID, and why platforms from social networks to dating apps to video conferencing will soon require proof of human verification.

David Haber speaks with Owen Jennings, executive officer and business lead at Block, about how the company rebuilt itself around AI agents, small squads, and internal tools like Goose and Builder Bot after restructuring more than 40% of its workforce. They discuss what it took to execute a major restructuring, how teams of three are now doing what teams of 14 used to, and how Block is shipping AI-native products like Money Bot and Manager Bot that generate custom interfaces on the fly for tens of millions of users.

a16z general partners Erin Price-Wright and Erik Torenberg speak with Doug Bernauer, founder and CEO of Radiant, and Drew Baglino, founder and CEO of Heron, about rebuilding American energy infrastructure. They discuss portable micro nuclear reactors, solid state power electronics, why delivery rather than generation is the real bottleneck, the case for modular manufacturing, and whether data centers are actually good for the grid.

This episode originally aired on The Twenty Minute VC with Harry Stebbings. Marc Andreessen explains why learning from past investment mistakes can be a trap, shares his framework for evaluating founder greatness through IQ, courage, and drive, and makes the case that venture investors should back the person over the business plan. They also discuss why AI is reconcentrating the tech industry in Silicon Valley, the concept of consumer surplus and where 99% of AI's value will actually go, and why the labor displacement narrative is fundamentally wrong.
