Summary
The article discusses the concept of 'Cognitive Debt' as a metaphor for how teams lose understanding of complex systems, particularly in the context of LLMs generating large amounts of code. It presents Margaret-Anne Storey's framework of three layers of system health for diagnosing and mitigating different types of debt that interact with each other. The author acknowledges some skepticism about debt metaphor proliferation but finds this approach sensible and useful for teams.
