"The way to build a complex system that works is to build it from very simple systems that work"
About this Quote
The subtext is anti-heroic. It pushes back against the lone-genius fantasy and toward iteration, modularity, and failure containment. Build “very simple systems that work” and you get components you can test, understand, and swap. Start with grand complexity and you get a black box whose failures are mysterious, expensive, and contagious. It’s basically the engineering version of institutional wisdom: make small promises, keep them, then layer.
Contextually, this is the worldview of someone who watched software eat the world and noticed what the hype rarely admits: most “innovations” collapse under their own interconnectedness. In an era of brittle platforms, overoptimized supply chains, and AI systems that behave like confident strangers, Kelly’s emphasis on working simplicity reads less like conservatism than survival. It’s a plea for a culture that respects boring competence, because that’s what scales without breaking.
