Brooks' No Silver Bullet thesis still applies to AI productivity claims

An essay revisits Fred Brooks' argument that software work splits into essence (deciding what to build) and accident (representing it), and applies it to current LLM productivity claims, arguing they compress only the accident.
If Brooks is right, any AI speedup measures how much of your work was representation labor rather than conceptual design. The framework gives engineers a concrete way to evaluate whether a tool addresses the actual hard problem or just the scaffolding around it.

Brooks splits software work into essence (specification, design, testing of the conceptual construct) and accident (syntax, boilerplate, representation labor), arguing tools can only compress the latter.
LLMs are described as the most effective accident-compressor ever built but still cannot address the essential difficulty of deciding what to build.
AI productivity claims implicitly reveal the accident-to-essence ratio in a role: a tenfold speedup means nine tenths of the work was representation, not conceptual design.
