Summary
Cognitive debt refers to the gap between a system's evolving structure and a team's understanding of its functionality and adaptability. Generative and Agentic AI may exacerbate this cognitive debt, prompting discussions within various communities about its implications.
Key Takeaways
- Cognitive debt refers to the gap between a system's evolving structure and a team's shared understanding of that system, impacting developers' ability to confidently make changes.
- Cognitive debt manifests in developers through loss of confidence, heavier review burdens, debugging friction, slower onboarding, and increased stress.
- Like technical debt, cognitive debt must be repaid by restoring the distributed theory of the system, which includes capturing intent and rationale across various mediums.
- AI's influence on development practices can accelerate cognitive debt if teams do not actively maintain shared understanding through living documentation and rigorous review processes.
