David Reich, a leading ancient DNA geneticist, explains why natural selection sped up around the Bronze Age. He describes how large-scale ancient DNA reveals rapid shifts in immune, metabolic, pigmentation, body-fat, and cognitive-related gene frequencies. He also offers a provocative rethinking of Neanderthals as genetically swamped modern-human offshoots and outlines the methods behind these discoveries.

Reiner Pope, MatX CEO and former Google engineer, turns a chalkboard into a tour of how frontier LLMs really run. He gets into batching, sparsity, MoE routing, rack design, pipeline parallelism, KV cache bottlenecks, and why decode is pricier than prefill. There’s also a fun detour into API pricing, long-context costs, and links between neural nets and cryptography.

Jensen Huang, Nvidia co-founder and CEO who helped pioneer GPU computing, dives into TPU rivalry, supply chain bottlenecks, and why Nvidia stays out of becoming a hyperscaler. He also gets into selling AI chips to China, CUDA’s ecosystem edge, and why the company bets on a few strong chip designs instead of many wild alternatives.

Michael Nielsen, a quantum computing pioneer and open science thinker, explores why science moves ahead long before proof catches up. He revisits Einstein, Darwin, heliocentrism, and isotopes to show how messy discovery really is. The conversation also dives into AlphaFold, rival research programs, alien tech trees, and why future civilizations might trade radically different ideas.

Terence Tao, UCLA mathematician and one of the era’s top problem-solvers, explores Kepler’s surprising path to planetary motion and why great theories can look worse before they win. He gets into AI flooding science with ideas, the bottleneck of verification, why breadth beats depth for now, and how writing, persuasion, serendipity, and human-AI teamwork shape discovery.

Dylan Patel, founder and chief analyst at SemiAnalysis, maps the real choke points behind AI compute growth. He gets into why old H100s can get more valuable, how Nvidia locked in TSMC capacity early, why memory may be the nastiest crunch ahead, and why ASML could become the limiting factor by 2030. They also touch on power buildouts, China timelines, robots, and Taiwan risk.

A deep look at the Anthropic–Pentagon dispute and why it matters for AI’s role in society. Discussion of how AI makes mass surveillance cheap and ubiquitous. Examination of government levers like supply-chain designations and procurement power. Debate over who AI should be aligned to and whether regulation hands power to a despot.

Ada Palmer, Renaissance historian, novelist, and composer at the University of Chicago. She explains how Italian city-republics and Roman cosplay shaped politics and learning. She traces printing’s real revolution from books to pamphlets and how distribution made Gutenberg fail. She links libraries, networks, and inquisitorial labs to the rise of shared scientific practices.

Dario Amodei, AI researcher and CEO of Anthropic, renowned for work on large-scale models and AI risk. He discusses why scaling and task-specific RL may generalize, how AI could diffuse through the economy, timelines for near-AGI-like capabilities, Anthropic’s compute and profitability choices, and governance and geopolitical risks tied to powerful models.

Elon Musk, entrepreneur and CEO of SpaceX and Tesla, leading large-scale projects in space, energy and AI. He discusses why space could become the cheapest place for AI within 36 months. He explains power limits on Earth and scaling solar and launches. He covers scaling humanoid robots, xAI’s approach to alignment and business, and chip and memory bottlenecks for massive compute.
