The Father of AI Assistant on Why Joy Comes Before Success - Kevin Surace

If you’re not using AI five times an hour, you’re already behind, says the man who built the first AI assistant back in 1998. Kevin explains why that pace is now the baseline, not the exception, for developers who want to stay employed. In this episode, Kevin Surace, the inventor of the first AI assistant and CEO of Appvance, joins to unpack six decades of AI evolution, from hidden Markov models to the LLM breakthroughs now powering coding agents. Kevin shares how his work at General Magic became the licensed technology behind Siri and Alexa, and how he ended up inventing post-training before anyone had a name for it. He explains why the only developers losing their jobs are the ones refusing to adopt AI, and how the role is shifting from writing code to specifying, coordinating, and testing it across a fleet of agents. Kevin also introduces AI Script Generation Bug Hunter, the testing technology uncovering thousands of bugs humans never catch. The conversation closes with his new book, Joy-Success Cycle, and why he believes joy has to come before success, not after.

Software Engineering Laws Every Developer Must Know in the AI Era - Milan Milanovic

Does moving faster with AI mean you get to skip the laws that governed every software project before it? Milan Milanovic argues the opposite, the old laws of software engineering now apply twice as hard. In this episode, Milan Milanovic, CTO and author of Laws of Software Engineering, returns to unpack why the laws that have quietly governed software projects for decades are more relevant than ever in the AI era. He walks through Gall’s Law and why AI lets teams generate complex systems on unvalidated assumptions faster than ever, Conway’s Law and how it now runs twice, shaping both human organizations and agent topologies, and Goodhart’s Law and the trap of “tokenmaxxing” as a metric. Milan also covers Hofstadter’s Law and the 90-90 rule, explaining why the last 10% of a project still takes as long with AI in the loop, and the Dunning-Kruger effect, where vibe coders overestimate their skills while senior engineers underestimate theirs. The conversation closes with his advice for juniors entering the field, his top five must-read books, and how he personally uses AI for research and planning rather than implementation. Key topics discussed: Gall’s Law: the trap of generating complex systems with AI Conway’s Law now runs twice, on humans and on AI agent topology Why software architects should help design your org chart Goodhart’s Law and the danger of “tokenmaxxing” as a metric The 90-90 rule: why AI’s last 10% still costs half the project Dunning-Kruger effect on vibe coders and experts Why less code beats more, even with AI writing it for free Timestamps: (00:00) Trailer & Intro (03:02) What Inspired Milan to Write Laws of Software Engineering?

Check out the Simba Voice Agents API for low-latency, natural back-and-forth interaction. Try it free at speechify.ai . Why do the same software delivery illusions keep fooling smart engineering teams? Elisabeth and Joel show how systems thinking, through signals and levers, helps you spot the illusions of progress, predictability, and control before they cost you. In this episode, Elisabeth Hendrickson and Joel Tosi, co-authors of Signals & Levers, share the story behind the book and trace the “software crisis” back to a 1968 NATO conference, arguing it never actually went away. They explain why software delivery is an adaptive sociotechnical system, and why treating it as a simple linear process leads leaders to pull the wrong levers. Elisabeth breaks down why proxy metrics like velocity are made-up numbers dressed up as science, and why cycle time tells a truer story. Joel walks through the CREATE framework (capacity, risk, execution, adaptability, trust, and economics), and how it can help leaders spot unintended consequences before they happen. They also dig into the three illusions leaders live under: illusion of progress, predictability, and control. The conversation closes with a candid look at where AI fits into all of this, when it amplifies good systems, when it makes bad ones worse, and why optimizing for learning matters more than ever.

From Technical Debt to Triple Debt: The Hidden Cost of AI-Generated Code

Is vibe coding quietly draining the thing that makes teams effective: their shared understanding? Margaret breaks down her new “triple debt” model, and why cognitive debt might be the one nobody’s tracking. In this episode, Margaret-Anne Storey, co-author of the SPACE framework and a leading developer experience researcher, returns three years after her first appearance to unpack her new “triple debt” model. She explains how technical debt is now joined by cognitive debt, the erosion of shared understanding across a team, and intent debt, the loss of the “why” behind decisions that agents also lack. Drawing on her Startup Studio course, where student teams built MVPs in minutes only to lose track of their own architecture weeks later, she walks through what pushed her to name these problems. The conversation covers cognitive surrender, developer fatigue from managing swarms of agents, and the warning signs leaders should watch for on their teams. Margaret also introduces Cognitive Tours, a tool inspired by sailing waypoints and log books, and the idea of strategic friction: deliberately slowing down to preserve understanding. She closes by revisiting the SPACE framework and why its five dimensions still hold up even as AI changes every question we ask about them. Key topics discussed: Why cognitive debt has always existed, just never named The triple debt model: technical, cognitive, and intent Cognitive surrender: accepting AI output without understanding Warning signs leaders should watch for on their teams Why the SPACE framework still holds up in the AI era Timestamps: (00:00:00) Trailer & Intro (00:02:42) How Has AI Transformed Software Development Over the Past Three Years?

Ex-Gojek CTO: Why the Age of AI Rewards Builders as Judgment Becomes Expensive

If expertise is becoming almost free, why is judgment becoming the most expensive skill in tech? Ajey Gore, former Gojek CTO, explains why the age of AI agents rewards builders over typists. In this episode, Ajey Gore, former Group CTO of Gojek and Operating Partner at Peak XV Partners, explains why coding agents are forcing software teams to rethink what “correct” really means. He argues that as expertise becomes cheap, judgment becomes the scarcest and most valuable skill in engineering. Ajey walks through why the classic developer-to-reviewer workflow no longer makes sense when agents can generate thousands of lines a day, and why trunk-based development, feature flags, and rigorous testing matter more than ever. He also shares how he built ClawStation solo, coordinating specialized AI agents through story cards instead of writing code by hand. The conversation covers why most organizations still fail to see returns from AI adoption, and what happens when leaders cut headcount without redesigning how work actually flows. Key topics discussed: Why judgment, not typing speed, is now the scarce skill The workflow mistake behind most failed AI adoption How Ajey built ClawStation solo without writing code Why he advocates trunk-based development to replace PRs The real risk of cutting headcount before rethinking work Why “earning time” matters as much as earning money Southeast Asia’s surprising advantage in the AI era Timestamps: (00:00:00) Trailer & Intro (00:04:10) What Has Life Been Like Since Leaving Peak XV?

The AI Productivity Paradox: Why 10X Output Doesn't Mean 10X Business Outcome

What if optimizing for AI output is actually slowing your company down? When code becomes nearly free to produce, the organizations still measuring productivity by output are solving the wrong problem. In this episode, Mik Kersten, author of “Project to Product” and the forthcoming “Output to Outcome,” shares why the real challenge of the AI era isn’t generating more code — it’s building organizations that can turn that output into customer and business value. Drawing on Carlota Perez’s model of technological revolutions and the theory of constraints, Mik explains how AI has removed the output bottleneck that software organizations were built around, and where the new constraints now live. He introduces three core models from the book — the outcome loop, the product operating model, and the outcome tree — as a framework for adapting how organizations plan, fund, and deliver value. Mik also addresses one of the most pressing decisions leaders face today: whether to cut headcount based on AI productivity gains, and why doing so without outcome visibility is a dangerous bet. The conversation covers how organizational structure, decision-making accountability, and leadership roles all need to shift — not just development practices. Timestamps: (00:00:00) Trailer & Intro (00:02:40) What Makes Output to Outcome Different From Project to Product? (00:05:02) Why Did Mik Write Every Word of This Book Without AI? (00:08:18) How Do the AI Prompts at the End of Each Chapter Work? (00:11:53) What Happens to Organizations When AI Makes Software Output 10 to 100 Times Cheaper?

The Hidden Stories Sabotaging Your Culture Change

Why do 70% of change efforts fail — even when leadership is fully committed? The answer isn’t strategy or resources; it’s the hidden stories people unknowingly carry that silently block every initiative. In this episode, Ronica Roth, author of “Practice Makes Culture” and co-founder of The Welcome Elephant, shares a practical framework for creating lasting organizational change. Drawing on 25 years of experience helping teams and companies transform, she explains why culture declarations and vision speeches alone never work — and what leaders at any level can do instead. Ronica introduces the concept of “welcoming elephants” — the emotional, systems, and room elephants that surface whenever change is attempted — and why acknowledging them is the first step toward real progress. She also unpacks why most culture lives beneath the surface, in hidden stories that employees carry without realizing it, and how those stories quietly undermine even well-designed initiatives. The conversation covers how to build psychological ownership so people invest in change rather than just comply with it, and why small, intentional daily practices — not grand overhauls — are what actually shift culture. The discussion also touches on applying these principles to AI transformation, where the emotional stakes are especially high and the hidden stories especially loud. Key topics discussed: Why 70% of change efforts fail — and what to do about it The three types of “elephants” blocking organizational change Hidden stories: the invisible force sabotaging your culture Why declaring a new culture is necessary but not sufficient How to create psychological ownership (not just buy-in) Using meetings as a daily practice for cultural change Leading AI transformation with vulnerability and structure The WOOP method for making personal behavior change stick Timestamps: (00:00:00) Trailer & Intro (00:02:43) Why Ronica Write a Book About IT Culture? (00:05:14) What Are the Three Types of Elephants That Hold Organizations Back? (00:11:05) Why Do 70% of Change Efforts Fail? (00:15:45) How Does Ronica Define the Different Layers of Culture? (00:20:57) Why Is Declaring a New Culture Necessary But Not Sufficient? (00:23:12) What Are the Three Pillars of Your Cultural Transformation Framework? (00:39:28) How Can You Turn Meetings Into a Daily Practice for Cultural Change? (00:48:51) How Can Leaders Address the Emotional Elephant of AI Transformation? (00:56:13) Can You Apply These Culture Change Principles to Personal Growth? (01:02:06) What Are the Five Culture Hacks for Scaling Cultural Impact?

Creator of Meta's Hack: Your AI Will Always Cheat — Here's How to Stop It

What if your AI coding agent is quietly cheating on your tests — and how do you stop it? Julien Verlaguet, who built the type system Meta used to migrate tens of millions of PHP lines, is now building Skipper: a closed-loop coding agent designed to make AI-generated code verifiably correct, without human intervention. In this episode, Julien Verlaguet, creator of the Hack programming language at Meta and co-founder of SkipLabs, explains why AI agents will always try to cheat — gaming tests, quietly modifying logic while doing something else, and declaring work done when it isn’t. He draws on his experience migrating Meta’s PHP codebase to a statically typed system, drawing sharp parallels between convincing engineers to trust a new type checker and building systems that can trust an LLM. Julien makes the case for spec-driven development with validation layers at every step, where separate AI instances verify correctness and the code-writing agent is locked out of touching tests. He shares the story of an LLM that silently swapped a union for an intersection while splitting a file — a subtle bug that passed all tests — and why no human would ever have made that mistake. He then walks through how Skipper works: you write a spec, hand over control, and a compiler-like agent produces correct, runnable TypeScript without back-and-forth, backed by a sound incremental type system, reachability analysis, and a reactive runtime that applies diffs in milliseconds. He closes with a grounded take on how the developer role is shifting — not disappearing — toward the kind of design, integration, and oversight work that always mattered most. Key topics discussed: Why AI agents will always try to cheat on your tests The union-vs-intersection bug an LLM introduced silently Spec-driven development to keep LLMs on track How to separate the AI that verifies from the one that fixes Skipper: a compiler-like closed-loop coding agent Sound, incremental TypeScript built for AI-speed iteration Hot-reloading state without restarting — in milliseconds Why developers are all becoming tech leads Timestamps: (00:00:00) Trailer & Intro (00:02:34) How Did Julien Create the Hack Programming Language at Facebook? (00:05:53) Does Static Typing Make Your Code More Secure? (00:09:54) How Did You Convince Facebook Engineers to Adopt Hack at Scale? (00:17:15) How Can Engineers Overcome Skepticism Toward AI Coding Tools? (00:22:44) Should Junior Engineers Trust AI-Generated Code? (00:29:44) How Do You Build Reliable Guardrails for LLM-Generated Code? (00:42:15) What Validation Strategies Prevent AI Agents From Cheating on Tests? (00:45:54) What Is Skipper and How Does a Closed-Loop Coding Agent Work? (00:54:59) How Does Skipper Compare to Claude Code in Terms of Correctness? (00:58:27) How Do You Get Started With Skipper and What Does the Output Look Like? (01:04:50) How Will the Software Developer Role Change in an AI-First World? (01:09:06) 3 Tech Lead Wisdom _____ Julien Verlaguet’s Bio Julien Verlaguet is a programming language designer and the Founder and CEO of SkipLabs. He is best known as the creator of Hack—the gradually typed language he built at Facebook that currently powers over 100 million lines of the company’s production code. After creating the open-source reactive framework Skip, Julien founded SkipLabs in 2022. His company recently launched Skipper, a closed-loop coding agent that takes a single prompt from a developer and returns a running, validated service.

Eric Ries: Why Good Tech Companies Go Bad, and How to Stop It

Why do companies with the best intentions end up betraying their customers, employees, and mission? Eric Ries calls it “financial gravity” — an invisible force that pulls even the most principled companies toward corruption, and understanding it is the first step to resisting it. In this episode, Eric Ries, entrepreneur and author of The Lean Startup and Incorruptible, shares why building a great company isn’t just about having a strong vision — it’s about building structures that protect that vision from external pressure. Eric revisits the core ideas behind the Lean Startup and MVP, explaining how the purpose of a minimum viable product is not to ship fast but to learn fast. He then introduces the central thesis of his new book: that the corruption we see in companies isn’t caused by bad people, but by a financial system that pulls organizations away from their values. Drawing on stories of Sol Price, FedMart, Costco, HEB, Novo Nordisk, and Anthropic, he shows that incorruptible companies are built through a combination of ethos — a deep operational commitment to doing right — and structural governance that resists outside pressure. He also unpacks how false metrics like OKRs can hollow out a company’s integrity over time, and how Mary Parker Follett’s concept of the “invisible leader” helps culture survive beyond any single founder or CEO. Key topics discussed: What “financial gravity” is and why even good companies fall to it The true purpose of an MVP (hint: it’s not about shipping fast) Why OKRs become dangerous false proxies over time Blueprint for building a truly incorruptible company Why Costco and Novo Nordisk resisted forces that killed FedMart Mary Parker Follett’s invisible leader explained Why Anthropic’s structure gives it a lasting competitive edge How everyday decisions become acts of systemic change Timestamps: (00:00) Trailer & Intro (02:31) What Two Mega-Trends Make Lean Startup More Relevant Than Ever?

Why Your AI Strategy Is Failing: The AI Paradox of Optimizing Coding Alone

What if faster coding is actually slowing your software delivery down? Most teams are pouring AI into the coding phase, but the real bottleneck is everywhere else. In this episode, Andrew Haschka, Field CTO at GitLab for Asia Pacific and Japan, explains why most AI strategies in software engineering are failing and what it takes to fix them. He introduces the AI paradox: teams invest heavily in AI-assisted coding, yet coding accounts for less than 20% of the software delivery lifecycle, leaving the biggest bottlenecks untouched. Andrew makes the case for intelligent orchestration — moving from isolated AI interactions to governed, end-to-end agentic flows that span planning, coding, testing, security, compliance, and release. He shares how a unified system of record forms the foundation for high-quality AI outcomes, and why fragmented tools and siloed context actively limit what AI can deliver. Drawing on real customer examples — including Ericsson’s 50% faster deployments and 130,000 hours saved in six months — he shows what a holistic approach actually looks like in practice. The conversation also covers how tech leads, developers, and junior engineers need to evolve their skills in a world where AI handles routine implementation. Andrew closes with a compelling argument: in the agentic era, governance isn’t just a compliance burden, it’s the primary source of competitive advantage.
