AI made volume cheap. It didn't make correctness cheaper. Why the scarce resource has shifted — and what that means for how marketing infrastructure gets built, verified, and maintained.

Resources vs Insights

Resources are reference documents — frameworks, definitions, and working concepts that don't date. Insights are articles: analysis, perspective, and field notes from real engagements. Both are worth reading, for different reasons.
