The hidden cost of AI code generation: cognitive overload during review
By
Vinicius Brasil
Summary
The article discusses the cognitive overload developers face when reviewing AI-generated code. While AI coding agents dramatically speed up implementation, they shift the bottleneck to code review. The author argues that reviewing code you didn't write or think through yourself creates a paradox: faster generation leads to slower, more mentally taxing review processes. The piece explores how AI makes implementation cheap while making judgment and review more expensive, ultimately questioning the true productivity gains of AI-assisted coding.

· 3 pulledEven when I follow good practices – like starting with the plan mode, dividing big tasks into phases, and shipping small changes – I still feel cognitive overload when reviewing something I haven't actually thought through myself.
With implementation getting faster and faster, the real bottleneck moves to reviewing the volume of code generated by AI.
AI can make implementation cheap while making review and judgment more expensive.
