Better Problems: The Power of Abstraction

Better Problems: The Power of Abstraction

Short summary

This article argues that abstraction in software design is not just about code readability but about managing cognitive load so developers can focus on problem shape rather than implementation mechanics. It contrasts a verbose 40-line API endpoint with a clean abstracted version to show how encapsulation frees working memory for higher-level reasoning. The author draws an analogy to everyday planning—like assessing your day for lunch plans—to illustrate that abstraction is a natural mental skill that should be applied deliberately in code.

  • •Abstraction reduces cognitive load by hiding implementation details behind meaningful symbols
  • •Encapsulation's real purpose is holding complexity at bay so the mind can work above it
  • •Developers already abstract instinctively in daily life; the skill is applying it deliberately in code
