Engineering Judgment Still Depends on Fundamentals and History

Two essays make a case for preserving engineering depth: one argues that fundamentals matter more as AI handles implementation, while the other argues that engineers neglect lessons from past work. Both concern the knowledge behind technical decisions.

Implementation still needs engineering judgment

As AI tools take on more implementation work, understanding what to build and how a system behaves remains essential. The author of Software Engineering fundamentals matter more argues that judgment and system understanding become the bottleneck. In that account, assistance with implementation increases the importance of the knowledge needed to direct and evaluate the work.

Past solutions belong in present decisions

Engineering knowledge also comes from work that has already happened. The companion essay argues that engineers avoid learning from past incidents and prior art, repeating mistakes that others have already solved. Its concern extends beyond individual technical skill to whether engineers draw on existing experience when making decisions.

The two arguments address complementary parts of engineering judgment: fundamentals help engineers reason about a system, while past incidents and prior art give them experience beyond their own. Together, the essays suggest that AI-assisted development still depends on both technical understanding and institutional memory.
