Beyond Code Review
Not that long ago, we were resigned to the idea that humans would need to inspect every line of AI-generated code. We’d do it personally, code reviews would always be part of a serious software practice, and the ability to read and review code would become an even more important part of a developer’s skillset.

In recent years, the idea that humans would need to inspect every line of AI-generated code seemed inevitable. Code reviews were expected to remain a cornerstone of serious software development, and the ability to read and review code was considered a critical skill for developers. However, this approach was always fraught with challenges. While AI could rapidly generate code, the time spent reviewing it often outweighed the benefits of automation. This realization isn't new; decades ago, the need to inspect assembly code generated by compilers diminished as the field matured. Similarly, code reviews, while occasionally catching style issues or poorly implemented algorithms, were often seen as an expensive solution to minor problems.
This shift in perspective has led to a reevaluation of software development practices. Specification-driven development (SDD) emerges as a promising alternative, emphasizing verification over review, specification over prompting, and testing over testing. The ultimate goal of software development isn't code that passes human review but systems whose behavior aligns with a well-defined specification that reflects the customer's needs.
Understanding the customer's requirements and designing an architecture to meet those needs requires human intelligence. Ankit Jain's work in "Latent Space" highlights the need to transition from asking whether the code is written correctly to asking whether we're solving the right problem. The specification process, which historically has been a weak point in the industry, plays a crucial role in this understanding.
Verifying that the system actually meets the specified requirements is just as important as writing the code. By focusing on specifications, developers can ensure that the software delivers the desired outcomes, reducing the reliance on time-consuming code reviews. This approach not only streamlines the development process but also enhances the overall quality of the software by aligning it with the customer's needs from the outset.
In conclusion, the future of software development may lie beyond traditional code reviews. By adopting specification-driven development and prioritizing the alignment of software with customer needs, the industry can move towards more efficient and effective systems. This shift requires a reevaluation of existing practices and a renewed focus on understanding the problems we aim to solve, rather than merely reviewing the code that addresses them.
