Originally published in June 2023, this conversation features a16z cofounder Marc Andreessen following the release of his nearly 7,000-word essay arguing that AI does not threaten our humanity. In a wide-ranging discussion with a16z General Partner Martin Casado, Andreessen expands on why he believes AI can dramatically amplify human potential, why its future should be shaped by open markets rather than regulation, and why fears of existential catastrophe are misplaced. Rather than destroying the world, he argues, AI may help save it. Read “Why AI Will Save the World”: https://a16z.com/2023/06/06/ai-will-save-the-world/

We’ve been checking in on the economic conditions in Venezuela for about a decade now. In response to the U.S. strike and the capture of Venezuelan president Nicolás Maduro this weekend, we’re re-surfacing this episode with an update.The original version ran in 2016, with an update in 2024.Back in 2016, things were pretty bad in Venezuela. Grocery stores didn’t have enough food. Hospitals didn’t have basic supplies, like gauze. Child mortality was spiking. Businesses were shuttering. It was one of the epic economic collapses of our time. And it was totally avoidable.Venezuela used to be a relatively rich country. It has just about all the economic advantages a country could ask for: Beautiful beaches and mountains ready for tourism, fertile land good for farming, an educated population, and oil, lots and lots of oil.But during the boom years, the Venezuelan government made some choices that add up to an economic time bomb.Today on the show, we run through the decisions that foreshadowed the collapse, and we hear from people in Venezuela in 2016 at a particularly low point for the economy, then again and in 2024 after a bounce back and a stabilization, in part due to the unlikely impact of the U.S. dollar. Pre-order the Planet Money book and get a free gift. / Subscribe to Planet Money+Listen free: Apple Podcasts, Spotify, the NPR app or anywhere you get podcasts.Facebook / Instagram / TikTok / Our weekly Newsletter.This original episode was hosted by Robert Smith and Noel King.

From undergraduate research seminars at Princeton to winning Best Paper award at NeurIPS 2025, Kevin Wang, Ishaan Javali, Michał Bortkiewicz, Tomasz Trzcinski, Benjamin Eysenbach defied conventional wisdom by scaling reinforcement learning networks to 1,000 layers deep—unlocking performance gains that the RL community thought impossible. We caught up with the team live at NeurIPS to dig into the story behind RL1000: why deep networks have worked in language and vision but failed in RL for over a decade (spoiler: it's not just about depth, it's about the objective), how they discovered that self-supervised RL (learning representations of states, actions, and future states via contrastive learning) scales where value-based methods collapse, the critical architectural tricks that made it work (residual connections, layer normalization, and a shift from regression to classification), why scaling depth is more parameter-efficient than scaling width (linear vs. quadratic growth), how Jax and GPU-accelerated environments let them collect hundreds of millions of transitions in hours (the data abundance that unlocked scaling in the first place), the "critical depth" phenomenon where performance doesn't just improve—it multiplies once you cross 15M+ transitions and add the right architectural components, why this isn't just "make networks bigger" but a fundamental shift in RL objectives (their code doesn't have a line saying "maximize rewards"—it's pure self-supervised representation learning), how deep teacher, shallow student distillation could unlock deployment at scale (train frontier capabilities with 1000 layers, distill down to efficient inference models), the robotics implications (goal-conditioned RL without human supervision or demonstrations, scaling architecture instead of scaling manual data collection), and their thesis that RL is finally ready to scale like language and vision—not by throwing compute at value functions, but by borrowing the self-supervised, representation-learning paradigms that made the rest of deep learning work. We discuss: The self-supervised RL objective: instead of learning value functions (noisy, biased, spurious), they learn representations where states along the same trajectory are pushed together, states along different trajectories are pushed apart—turning RL into a classification problem Why naive scaling failed: doubling depth degraded performance, doubling again with residual connections and layer norm suddenly skyrocketed performance in one environment—unlocking the "critical depth" phenomenon Scaling depth vs. width: depth grows parameters linearly, width grows quadratically—depth is more parameter-efficient and sample-efficient for the same performance The Jax + GPU-accelerated environments unlock: collecting thousands of trajectories in parallel meant data wasn't the bottleneck, and crossing 15M+ transitions was when deep networks really paid off The blurring of RL and self-supervised learning: their code doesn't maximize rewards directly, it's an actor-critic goal-conditioned RL algorithm, but the learning burden shifts to classification (cross-entropy loss, representation learning) instead of TD error regression Why scaling batch size unlocks at depth: traditional RL doesn't benefit from larger batches because networks are too small to exploit the signal, but once you scale depth, batch size becomes another effective scaling dimension — RL1000 Team (Princeton) 1000 Layer Networks for Self-Supervised RL: Scaling Depth Can Enable New Goal-Reaching Capabilities: https://openreview.net/forum?id=s0JVsx3bx1 Chapters 00:00:00 Introduction: Best Paper Award and NeurIPS Poster Experience 00:01:11 Team Introductions and Princeton Research Origins 00:03:35 The Deep Learning Anomaly: Why RL Stayed Shallow 00:04:35 Self-Supervised RL: A Different Approach to Scaling 00:05:13 The Breakthrough Moment: Residual Connections and Critical Depth 00:07:15 Architectural Choices: Borrowing from ResNets and Avoiding Vanishing Gradients 00:07:50 Clarifying the Paper: Not Just Big Networks, But Different Objectives 00:08:46 Blurring the Lines: RL Meets Self-Supervised Learning 00:09:44 From TD Errors to Classification: Why This Objective Scales 00:11:06 Architecture Details: Building on Braw and SymbaFowl 00:12:05 Robotics Applications: Goal-Conditioned RL Without Human Supervision 00:13:15 Efficiency Trade-offs: Depth vs Width and Parameter Scaling 00:15:48 JAX and GPU-Accelerated Environments: The Data Infrastructure 00:18:05 World Models and Next State Classification 00:22:37 Unlocking Batch Size Scaling Through Network Capacity 00:24:10 Compute Requirements: State-of-the-Art on a Single GPU 00:21:02 Future Directions: Distillation, VLMs, and Hierarchical Planning 00:27:15 Closing Thoughts: Challenging Conventional Wisdom in RL Scaling

Originally aired in October 2023, this episode centers on Marc Andreessen’s essay The Techno-Optimist Manifesto, which lays out his vision for the future of technology. The piece sparked widespread discussion across traditional and social media by challenging the prevailing pessimistic narrative around technology and arguing instead that it can be a force for growth, progress, and abundance. In this one-on-one conversation, based on listener questions from X (formerly Twitter), a16z cofounder Ben Horowitz and Marc discuss how technological advances can improve quality of life, support marginalized communities, and shape how we think about humanity’s long-term future.
