   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.

   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.

   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.
