Most architects have been thinking about coupling the wrong way for years. Not as something to understand and design deliberately but as something to eliminate. That misunderstanding is behind most of the distributed monolith disasters of the microservices era.

In this episode, Vlad, author of Balancing Coupling in Software Design, shares what he learned after building a textbook distributed monolith while following best practices to the letter. We dig into why coupling is unavoidable, what the three dimensions of coupling actually are, and why strategic DDD consistently beats tactical DDD for large systems.

But the conversation takes an unexpected turn: Vlad argues AI is the third coming of Domain-Driven Design. When you prompt an AI in natural language, ambiguous domain models don't just slow your team down — they get baked silently into generated code. The same discipline that makes systems evolvable turns out to be the foundation for working effectively with AI.
