Rather than theorizing, the architect wrote actual code to test each approach. The key insight: one design option dismissed as a throwaway turned out to be the best performer — something that could never have been discovered through pure design thinking alone. The story makes a case for validating designs through implementation and empirical testing rather than relying solely on intuition or architectural reasoning. ## Full article daily.dev links to this article rather than hosting it.
