“Simplicity is prerequisite for reliability.”
Dijkstra argued that intellectual control over software depends on disciplined reasoning and structures people can actually comprehend. Reading Edsger Dijkstra in the setting of “EWD498 — How Do We Tell Truths That Might Hurt?” changes how the quotation lands. The year 1975 identifies the documented source, while June 9 is only this series calendar position. Returning to the original work verifies authorship, clarifies the problem under discussion, and marks where modern interpretation begins.
Reducing unnecessary states, dependencies, and special cases makes correct behavior easier to establish and maintain. For a present-day team, the idea becomes useful when it changes a decision instead of decorating a slide. A reviewer can apply it to an interface, architecture, dataset, workflow, classroom, or governance rule, naming the desired outcome and the evidence that could challenge a preferred story.
A simple surface can hide complexity elsewhere, and some domains remain inherently difficult despite careful design. This qualification keeps the sentence from becoming a universal slogan. Technical results live inside organizations, markets, laws, and communities, where a narrow benchmark rarely settles the whole question. Responsible use makes assumptions visible, records tradeoffs, and asks who gains convenience and who inherits risk.
Distributed services, safety-critical code, and software supply chains reward designs that minimize hidden interactions and failure modes. The quotation endures as a method rather than a formula: understand the source, test the claim in its new environment, disclose important limits, and revise the implementation when real conditions disagree. What matters is whether the idea helps make technology more understandable, dependable, useful, and answerable to the people it affects.

The strongest modern use connects the principle to evidence, states tradeoffs, and keeps responsibility visible.
