Hi there! We start the new podcast season with a bang, by hosting Martin Fowler!
Martin is Chief Scientist at Thoughtworks, he is one of the original signatories of the Agile Manifesto, and author of several legendary books, among which there is Refactoring, which shares the name with this podcast and newsletter.
With Martin we talked about:
-
🤖 The Impact of AI on Software Development — from the dev process, to how human learning and understanding changes, to the future of engineering jobs.
-
🏦 The Technical Debt Metaphor — why it has been so successful, and Martin’s advice on dealing with it.
-
🔄 The State of Agile — the resistance that still exists today against agile practices, and how to measure engineering effectiveness.
Here are also useful resources mentioned by Martin in conversation:

Let’s dive in 👇
Martin shares his views on how AI is influencing software development, emphasizing that it’s still early days and the technology is evolving rapidly. He notes that AI tools are good at generating drafts but require human oversight to ensure quality.
“It’s good at coming up with drafts, but you have to look at the drafts because it’s going to include mistakes.”
He cautions that over-reliance on AI-generated code may reduce learning opportunities for developers:
-
🧠 Importance of learning — If developers don’t engage deeply with the code, they may not understand the systems they’re building, which can hinder future adaptability.
-
⚠️ Potential pitfalls — AI can replicate a junior developer’s output but lacks the experience and judgment of a senior developer.
-
💡 Skill shift — Developers need to learn how to effectively integrate AI into their workflow to stay relevant.
Martin suggests that while AI can enhance productivity, it’s crucial for developers to focus on learning and understanding the tools they use.
Emphasizing the critical role of nurturing junior developers into senior roles, Martin highlights the long-term benefits for organizations.
“One of the most important properties of a junior developer is the fact that you can turn them into a senior developer.”
He believes that investing in talent development is essential:
