The Lost Discipline: Why Modern Software Feels Slow

The modern computing landscape presents a paradox: while hardware has achieved "miraculous" levels of power—featuring dozens of cores, gigabytes of RAM, and ultra-fast storage—software performance often feels slower and less responsive than the systems of the 1990s. This document analyzes the root causes of this "software bloat," identifying a shift from the "discipline of scarcity" to a modern "permission to waste" hardware resources.The analysis reveals that the decline in efficiency is not due to a lack of programmer talent, but rather a combination of excessive abstraction layers, misaligned business incentives, a loss of "systems literacy," and the uncritical use of third-party dependencies. Furthermore, the rise of AI-generated code threatens to accelerate this trend by producing "plausible but unoptimized" software at industrial speeds. To combat this, organizations must elevate performance to a first-class build artifact, implement strict performance budgets, and reintegrate the "taste" and discipline that once characterized software development.
