Are you making critical decisions without consulting AI? Greg argues it’s now irresponsible for any leader to make high-stakes decisions without talking to AI first.

In this episode, Greg Shove, CEO of Section and a multi-time founder with 30 years of entrepreneurial experience, shares how AI is fundamentally different from any previous technology wave. Unlike traditional software that makes us more productive within our existing boundaries, AI allows us to jump capability boundaries – enabling individuals and organizations to do things they simply couldn’t do before.

Greg explains why most enterprise AI rollouts are failing (hint: they’re treating AI like software when it’s actually co-intelligence), how to cultivate resilience through multiple startup failures, and the practical strategies for getting teams to adopt AI (from simple hacks like putting a post-it note on your monitor to creating an entire AI-dedicated screen).

This conversation goes beyond the hype to explore both the superpowers and limitations of AI, the real organizational outcomes you can expect (spoiler: it’s not just about layoffs), and why moving from efficiency to creation is the key to unlocking AI’s true potential in your organization.

Key topics discussed:

• Why AI breaks capability boundaries unlike any other tech
• Treating AI as a thought partner, not just a productivity tool
• Why most large organizations fail at AI deployment
• Managing workforce anxiety during AI transformation
• The four possible team outcomes when rolling out AI
• Moving from efficiency (cut) to growth (create) with AI
• The Post-it note hack that changed how teams use AI daily
• Walking the walk: leading authentically in AI adoption

Why do organizations constantly complain about having too much technical debt? Because they’re solving the wrong problem.

In this episode, Dr. Andrew Brown, author of “Taming Your Dragon: Addressing Your Technical Debt,” reveals a profound insight: technical debt isn’t fundamentally a technical problem. It’s a trade-off problem rooted in human bias, organizational systems, and economic incentives. Through his innovative “Technical Debt Onion Model,” Andrew shows how decisions about code quality happen across five interconnected layers, from individual cognitive biases to wicked problem dynamics.

Andrew explains why the financial debt analogy is dangerously misleading and, more importantly, how others can rack up debt you’ll eventually pay for. Drawing from behavioral economics, systems thinking, and organizational theory, he reveals why our emotions, not logic, drive most technical decisions, and how to work with this reality rather than against it.

Key topics discussed:

• Why technical debt is a trade-off problem, not technical
• How emotions override logic in critical decisions
• The Technical Debt Onion Model framework explained
• Principal-agent problems sabotaging your codebase
• Externalities: who pays for shortcuts taken today?
• Why burning down debt is already too late
• Ulysses contracts for managing future obligations
• Systems thinking applied to software development
• Wicked problems: why different teams see different solutions
• AI’s impact on technical debt creation

Simon Wardley’s Bio
Simon Wardley is a researcher, former CEO, and the creator of Wardley Mapping, a powerful method for visualizing and developing business strategy. His journey began accidentally after a bookseller recommended Sun Tzu’s The Art of War, which sparked a fascination with understanding the competitive “landscape.”

As the former CEO of an online photo service acquired by Canon, he felt like a “fake CEO,” leading with stories while lacking true situational awareness. This led him to discover that almost all business “maps” were merely graphs, prompting him to develop his own mapping technique. Today, his work is used by organizations like NASA and taught at multiple MBA programs, helping leaders to “look before they leap” and navigate complex technological and market shifts, including the current disruption caused by AI.

“Architecture is something that has to emerge naturally from the code. If it doesn’t make the code better, more elegant, and more flexible, then you should not be doing it.”

Why do so many developers have a love-hate relationship with ORM? The creator of Hibernate reveals the real reasons behind the controversy and what’s being done to fix the fundamental issues.

In this episode, Gavin King, the creator of Hibernate, shares the story behind its creation, from a debate with his boss to its rise as a popular open-source. He dives deep into why developers often dislike ORM, pinpointing the “magic” of the stateful persistence context as a major pain point.

Gavin explains how modern specifications are fixing these historical issues with an emphasis on type safety and more explicit, stateless operations, giving developers greater control.

Key topics discussed:

• The origin story of Hibernate and the early frustrations with Java EE
• The single biggest mistake that led some developers to hate ORM
• Why type safety matters and how the new Jakarta specifications enable type-safe queries
• Why architecture should emerge from code, not from whiteboard diagrams
• A critique on industry dogmas and architecture best practices, including DDD aggregates
• Why disagreement is essential for healthy engineering teams
