Comparative Advantage in Software
The article applies the economic theory of comparative advantage to software development, arguing that developers and teams should focus on tasks where they have the greatest relative efficiency, rather than trying to do everything. It suggests that specializing and leveraging existing tools, libraries, and services can lead to higher productivity and better outcomes in building software.
Background
- The article uses the economic concept of **comparative advantage** (Ricardo's theory that countries benefit from specializing in what they do relatively best, even if they're worse at everything) to analyze software development.
- It argues that AI code assistants (like GitHub Copilot, Cursor) are changing developers' productivity so much that teams should rethink **who builds what**, not just how fast they build it.
- Key implied reference: the classic example of a lawyer vs. a secretary — a lawyer is better at both law and typing, but still hires a secretary because the opportunity cost of typing is too high. The article applies similar logic to senior vs. junior engineers and to different programming languages.
- The piece is aimed at software leaders and builders in the English-language tech world, written during the 2024–2025 surge in generative AI coding tools.
