Join Patrick McKenzie (patio11) as he discusses how decisions, technology, culture, and incentives shape our finance, technology, government, and more, with the people who built (and build) those Complex Systems.

    Home improvement lending with fewer bankers and more computers

    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.– Full transcript available here: www.complexsystemspodcast.com/home-improvement-lending/ – Sponsor: MercuryThis episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.

    Talking to the Bank of England about systemic risk and systems engineering

    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.– Full transcript available here: www.complexsystemspodcast.com/talking-to-the-bank-of-england/ – Sponsor: MercuryThis episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.

    Narrative, mastery, and character bleed in games, with Ricki Heicklen

    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. – Full transcript available here: www.complexsystemspodcast.com/narrative-mastery-character-bleed-in-games-with-ricki-heicklen/ – Sponsor: MercuryThis episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.

    Bits and bricks: Oliver Habryka on LessWrong, LightHaven, and community infrastructure

    Patrick McKenzie (patio11) is joined by Oliver Habryka, who runs Lightcone Infrastructure—the organization behind both the LessWrong forum and the Lighthaven conference venue in Berkeley. They explore how LessWrong became one of the most intellectually consequential forums on the internet, the surprising challenges of running a hotel with fractal geometry, and why Berkeley's building regulations include an explicit permission to plug in a lamp. The conversation ranges from fire codes that inadvertently shape traffic deaths, to nonprofit fundraising strategies borrowed from church capital campaigns, to why coordination is scarcer than money in philanthropy.– Full transcript available here: www.complexsystemspodcast.com/bits-and-bricks-oliver-habryka/– Sponsor: MercuryThis episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.

    Building institutions that bend towards truth, with Clara Collier of Asterisk Magazine

    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.– Full transcript available here: www.complexsystemspodcast.com/building-institutions-that-bend-towards-truth-with-clara-collier-of-asterisk-magazine/– Sponsor: MercuryThis episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.

    How blogging went legit, with Substack CEO Chris Best

    Patrick McKenzie is joined by Chris Best, CEO of Substack, to discuss how the platform created new economic infrastructure for independent media. They explore Substack's evolution from a simple newsletter tool to a full media network, the revenue guarantee program that attracted prominent writers, and the company's principled stance on press freedom during the "cancel culture" years. Chris explains how subscription-based business models create better incentive alignment than attention-based advertising, and discusses new features like AI-powered video production and Substack Defender, their legal protection program for writers facing lawsuits.– Full transcript available here: www.complexsystemspodcast.com/how-blogging-went-legit-with-substack-ceo-chris-best/ –Sponsor: MercuryThis episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.

    Prestige media, new media, and the US government, with Kelsey Piper

    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. – Full transcript available here: www.complexsystemspodcast.com/prestige-media-new-media-with-kelsey-piper/– Sponsor:  This episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.

Emmett argues that current AI safety approaches focused on "systems of control" are fundamentally flawed and proposes "organic alignment" instead—where AI systems develop genuine care for their local communities rather than following rigid rules. – Full transcript available here: www.complexsystemspodcast.com/ai-alignment-with-emmett-shear/–Sponsor: MercuryThis episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.
