In this episode, Patrick McKenzie reads his essay about the financial infrastructure that makes buying windows painless. When a window installer can originate, underwrite, and fund a $25,000 loan in 15 minutes before leaving your house, it's because four parties—window companies, facilitating platforms, specialized banks, and capital providers—have built a system that actually works. Patrick explains how modern consumer lending learned from 2008 to create better underwriting, clearer compliance, and properly distributed risk, all in service of enabling commerce in the real economy.

Patrick McKenzie (@patio11) shares his remarks to the Bank of England on critical vulnerabilities in financial infrastructure. Drawing from the July 2024 CrowdStrike outage which brought down teller systems at major US banks, Patrick discusses how regulatory guidance inadvertently created dangerous software monocultures. He also examines the stablecoin market, its impressive growth, and the elephant tethered to the room. He also delivers a message from Silicon Valley to other centers of power on the urgent necessity of waking up regarding AI, which almost the entire world currently far underrates.

Patrick McKenzie (patio11) is joined again by Ricki Heicklen to discuss Metagame 2025, a conference where 250 attendees were divided into Purple and Orange teams competing for territories across campus. Patrick built a complete roguelike RPG in 25 days using LLMs, discovering that providing minimal world-building context transformed generic fantasy outputs into emotionally resonant storytelling. They discuss the power and responsibility of game designers, how games create pedagogical experiences that traditional teaching cannot, and what happens when the line between player identity and character identity starts to blur.

Patrick McKenzie is joined by Clara Collier, editor and publisher of Asterisk Magazine, to discuss how we create institutions that bend towards truth. Clara explains why she launched a quarterly print magazine in the Internet age. She traces how 19th century German universities invented the modern infrastructure for rewarding knowledge production and training researchers at scale, and where our public science communication falls short of that heritage. The conversation examines why institutional trust has declined, particularly around science communication and public health, and whether we can rebuild trust in knowledge-producing institutions.

Patrick McKenzie is joined again by Kelsey Piper, who has co-founded "The Argument" to revive principled liberal discourse after witnessing how coordinated social media campaigns replaced substantive disagreement in newsrooms. Their conversation traces this institutional breakdown from media to government, examining how DOGE's spreadsheet-driven governance nearly destroyed PEPFAR, America's most successful foreign aid program that had driven infant coffin manufacturers out of business across Africa. The discussion ultimately argues that rebuilding both effective journalism and competent governance requires returning to the hard work of engaging with ground-level reality rather than managing online narratives.

Patrick McKenzie (patio11) is joined by Bean, a pseudonymous defense industry expert, to explore the intellectual crossovers between military and civilian domains. The conversation reveals how the defense industry's fundamental constraint of having only one customer (a monopsony) creates entirely different incentives than tech, leading to conservatism and 30-50 year product lifecycles. Bean argues that drones are largely modern iterations of cruise missiles we've had since the 1950s, and explains why current anti-drone defenses make swarm attacks less threatening than headlines suggest.

This week on Complex Systems, Patrick McKenzie (patio11) is joined by Joel Becker from METR. They discuss groundbreaking research on AI coding assistants.
Joel et al’s randomized controlled trial of 16 expert developers working on major open source projects revealed a counterintuitive finding: despite predictions of 24-40% speed improvements, developers actually took 19% longer to complete tasks when using AI tools, even though they retrospectively believed they were 20% faster. The conversation explores why even sophisticated professionals struggle to accurately assess their own productivity with AI tools, the industrial organization of software development, and the implications for AI's recursive self-improvement in research and development. It also touches on other perspectives from software developers using these tools professionally, and where we can expect them to improve rapidly.

In this solo episode, Patrick McKenzie reads his classic essay "Seeing Like a Bank," exploring why financial institutions often appear to have no memory of previous customer interactions despite being excellent at tracking money itself. He breaks down the complex web of legacy systems, tiered support structures, and regulatory constraints that create Kafka-esque experiences for bank customers. Using the lens of institutional legibility borrowed from "Seeing Like a State," Patrick explains how banks' technical architecture and organizational design choices—from core processing systems to customer service tiers—systematically generate the dysfunction that customers experience when things go wrong.

Ricki shares war stories from the bootcamp trenches—infinite loop bugs that mirror Knight Capital's disaster, WiFi outages that create unexpected trading opportunities, and that the most successful trading teams often focus on internal team communication even more than trade execution or technical acumen.

Patrick McKenzie is joined by Adam Jarvis, author of the Public Service substack and a New Zealand civil engineer and public sector veteran. They discuss how political capital constraints, funding misalignment across government levels, and accumulated regulatory "scar tissue" make infrastructure projects extraordinarily difficult. The conversation reveals why replacing a water pipe now costs more in planning than the entire project did a decade ago, and how talent sorting has drained capacity from public institutions. Despite these challenges, Patrick and Adam find reasons for optimism about reforming government capacity.

In this episode, Patrick McKenzie (@patio11) is joined by Jennifer Li, a general partner at a16z investing in enterprise, infrastructure and AI. Jennifer breaks down how AI workloads are creating new demands on everything from inference pipelines to observability systems, explaining why we're seeing a bifurcation between language models and diffusion models at the infrastructure level. They explore emerging categories like reinforcement learning environments that help train agents, the evolution of web scraping for agentic workflows, and why Jennifer believes the API economy is about to experience another boom as agents become the primary consumers of software interfaces.

In this episode, Patrick McKenzie (patio11) recorded with Zvi Mowshowitz (TheZvi) live at the LessOnline conference. They explore practical strategies for getting better results from large language models. Zvi explains how to customize AI behavior through thoughtful system prompts, while Patrick shares techniques for using LLMs as writing partners and research assistants. They discuss the evolving relationship between content creators and AI training data, touching on the emerging field of "generative engine optimization" (GEO). The conversation also covers multimodal capabilities, recursive AI use, and strategies for avoiding common failure modes like hallucination and sycophancy.
