Clean Code Is a Lie. Here’s What’s Actually Destroying Your Performance.
The ‘clean code’ movement taught us to optimize for readability β tiny methods, layers of abstraction, interfaces everywhere. But what feels clean to your brain runs like garbage on silicon. Every abstraction is a tax on CPU cycles, cache lines, and memory. The real clean code isn’t pretty prose; it’s code that respects the hardware’s execution model. We’ve been optimizing for the wrong bottleneck for years.
