Mark Dominus challenges common assumptions about code review in a recent discussion on Mathstodon. Many developers believe the primary goal is catching bugs, but Dominus argues this approach is fundamentally flawed. He states that attempting to find bugs through code review means living in a fool's paradise, as bug detection through static examination is generally impossible.

Instead, Dominus identifies code maintainability as the true purpose of code review. When reviewers struggle to understand code logic or flow, it signals future maintenance problems. Addressing these clarity issues while the original author is still available prevents costly refactoring later. This reframing shifts focus from defect hunting to code quality assessment.

The practical implication is significant for development teams. Rather than treating code review as a final checkpoint for bugs, teams should use it as an opportunity to improve code readability and structure. This approach leads to more sustainable codebases and reduces long-term technical debt. Reviewers become collaborators focused on improving developer experience, not just gatekeepers preventing defects.

Dominus emphasizes that unclear code represents the real risk in software development. When code becomes difficult to modify or extend, maintenance costs compound over time. Teams that prioritize clarity during review processes build systems that age gracefully rather than accumulating hidden complexity.
