After Hierarchy
Hierarchy was never about organising people. It was always about routing information. That problem just got solved.
The Router Problem
Think about what a middle manager actually does. They take information from the people below them and pass it up. They take decisions from above and pass them down. They schedule meetings so information can move sideways. They write status reports. They manage inboxes so nothing falls through.
That is not leadership. That is routing.
In the 20th century, humans were the cheapest available routers. So organisations were built around them. The org chart is a routing map — who handles information from whom. Hierarchy was not a statement about human worth or ability. It was an engineering solution to a communications problem.
The cost was real. Every message that passed through a human layer also passed through human attention, human mood, human politics. The signal degraded. Decision fatigue accumulated at every node. The further from the source, the more noise.
Nobody complained too loudly. There was no better option.
The Unix Lesson
In 1969, a small team at Bell Labs built something that would quietly change the world. Their operating system had one unusual rule: programs should do one thing and do it well. Not one program that does everything. Many small programs, each with one clear job, connected by clean interfaces.
A pipe let you feed the output of one program directly into another. A dozen small tools could combine into a system that none of them could build alone.
The Art of Unix Programming calls it: "Rule of Modularity — Write simple parts connected by clean interfaces."
This principle — call it unixification — became the standard beneath the internet. Email servers, web browsers, payment gateways, search engines. All of them: small parts, stable interfaces, composable into larger systems. No single company owns the whole stack. Anyone can build a piece. If the interface is standard, the piece fits.
The reason the internet compounded into something nobody planned: open standards. Nobody owns the rules. Everyone builds on the same floor.
Gall's Law explains why this works: a complex system that works is invariably found to have evolved from a simple system that worked. Complexity built on messy foundations collapses under its own weight. Complexity built from composable parts survives.
