Achieving results in the physical world, with Adam Jarvis of “Public Service”
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.Complex Systems now has video episodes as well.

The AI infrastructure stack with Jennifer Li, a16z
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.–Full transcript: www.complexsystemspodcast.com/the-ai-infrastructure-stack-with-jennifer-li-a16z/–Sponsor: VantaVanta automates security compliance and builds trust, helping companies streamline ISO, SOC 2, and AI framework certifications.

Getting better at LLMs, with Zvi Mowshowitz
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. –Full transcript: www.complexsystemspodcast.com/getting-better-at-llms-with-zvi-mowshowitz/–Sponsor: VantaVanta automates security compliance and builds trust, helping companies streamline ISO, SOC 2, and AI framework certifications.

Machine learning meets malware, with Caleb Fenton
Patrick McKenzie (patio11) discusses software reversing and AI's transformative impact on cybersecurity with Caleb Fenton, co-founder of Delphos Labs. They explore how LLMs are revolutionizing the traditionally tedious work of analyzing compiled binaries, the nation-state cyber warfare landscape, and how AI is shifting security from reactive to proactive defense. They cover the technical details of malware analysis, the economics of vulnerability detection, and the broader implications as both defenders and attackers gain access to increasingly powerful AI tools. –Full transcript available here: https://www.complexsystemspodcast.com/machine-learning-meets-malware-with-caleb-fenton/–Sponsor: MercuryThis episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.

How to negotiate your salary package
In this episode, Patrick McKenzie (patio11) revisits his widely-shared negotiation essay, which he notes may be the most impactful thing he's done in his career aside from VaccinateCA. The essay covers the psychology and tactics of salary negotiation, emphasizing that engineers have turned being bad at negotiation into a "perverse badge of virtue" and that the financial stakes are enormous—a small salary increase compounds over decades to six-figure differences. Patrick walks through practical advice including never giving a number first, understanding how employers actually think about compensation costs, and reframing negotiation as a professional business discussion rather than something morally questionable. –Full transcript available here:www.complexsystemspodcast.com/how-to-negotiate-your-salary-package/–Sponsor: MercuryThis episode is brought to you by Mercury, the fintech trusted by 200K+ companies — from first milestones to running complex systems.
