   Heimir Thor Sverrisson: Architecture First, Tech Debt Second

   Sustainable software starts with sustainable architecture. Heimir Thor Sverrisson joins Robby to discuss why poor architectural decisions make maintenance a losing battle, how technical debt should be managed, and why adding more CPUs won’t always fix your performance problems.

   Matija Šošić: Abstractions Aren’t Going Anywhere

   What happens to frameworks when generating code becomes cheap enough that nobody particularly cares about the boilerplate anymore? Matija Šošić joins Robby to talk about boring software, abstraction as a form of restraint, Wasp’s decision to abandon its custom DSL, and why AI may make good abstractions more valuable rather than less.

   José Valim: Designing a Language You Can Maintain for Decades

   What changes when the software you’re maintaining is a programming language that thousands of other applications depend on? José Valim joins Robby to trace Elixir from a frustrating Rails concurrency bug to a language designed for long-term evolution, then looks at how AI is changing documentation, dependencies, coding tools, and open-source maintenance.

   John Athayde: Maintaining the User Side of Software

   The user interface of a long-lived application carries years of technical decisions, design choices, and organizational history. John Athayde joins Robby to explore how teams can untangle that front-end sprawl, and what changes when AI makes it much easier to analyze and rewrite what came before.

   Kristin Isaac: The Customer Doesn’t Care About Your Technical Debt

   Customers don’t ask you to pay down technical debt. They notice when the product is slow, unreliable, or keeps breaking in the same damn way. Kristin Isaac joins Robby to explore how engineers can translate invisible maintenance work into customer and business impact… and why that skill may become even more important as AI makes software faster to create than to understand.

   Diana Pfeil: Building Confidence in Probabilistic Systems

   Software powered by AI can change its behavior without a deployment, leaving teams to maintain code, data, prompts, models, and the uncertainty between them. Diana Pfeil joins Robby to explain how evals, production monitoring, and a preference for simpler models help teams build confidence in systems they cannot completely predict.

    Chris Coyier: The Long Game of Maintaining CodePen

    Chris Coyier, co-founder of CodePen, joins Robby to reflect on what it takes to maintain software over the long haul. Drawing from CodePen’s 15-plus-year journey, Chris shares lessons about balancing stability with innovation, navigating technical debt, and gradually evolving a product without losing sight of the people who depend on it. They discuss CodePen’s origins, the team’s ongoing migration from Rails to Go, the realities of building with a small engineering team, and why maintainability is often more about people than code.
