When a team delegates its technical thinking to AI, it risks losing something irreplaceable: a deep understanding of its own system.
An organization that massively delegates to AI tools without cultivating internal understanding creates a dangerous dependency. Not a dependency on a tool β tools change β but a cognitive dependency: developers no longer truly understand the code they maintain. This loss of knowledge capitalization is silent and cumulative.
The classic symptom: a team using Copilot intensively produces functional code quickly, but two years later nobody can explain why certain architectural decisions were made. Documentation is lacking because code was generated too fast to be understood. The bus factor β the number of people whose departure would endanger the project β drops to zero, because the knowledge is in the model, not in people's heads.
The solution is not to reject AI, but to establish explicit capitalization practices. ADR (Architecture Decision Record) documents important decisions and their reasoning β regardless of who or what produced the code. Regular code walkthrough sessions force developers to explain code to their colleagues. Pair programming with AI as a tool (not as the driver) preserves human understanding. And rigorous code reviews, even β especially β for generated code, maintain collective knowledge.
- Document architectural decisions in ADRs
- Organize regular code walkthrough sessions
- Use AI as a tool, not a decision-maker
- Measure your team's bus factor regularly
