Introduction to the Global Chip Industry

Modern global power is no longer defined by the strength of steel or the size of nuclear arsenals, but by the microscopic switches known as transistors. These tiny components, etched onto silicon chips, form the brain of every piece of electronic equipment, from smartphones to sophisticated missile systems. Chris Miller explains that while we often think of the digital world as a collection of abstract data, it actually relies on a physical infrastructure of semiconductors that process billions of electrical currents every second. This industry has become the foundation of the modern economy, yet it is built upon a supply chain so concentrated that it represents a massive geopolitical vulnerability.

The rapid advancement of this technology is governed by Moore's Law, the observation that the number of components on a chip doubles roughly every year or two. This exponential growth has transformed the simple chips of the 1960s into modern processors that house nearly twelve billion transistors. This progress was driven by a unique combination of scientific genius in Silicon Valley, massive government research funding, and a relentless drive for manufacturing efficiency. Without this constant doubling of computing power, the modern digital economy would simply not exist.

While the United States remains a leader in chip design, the actual fabrication of the world's most advanced chips has shifted almost entirely to East Asia. The Taiwan Semiconductor Manufacturing Company produces about a third of the world's new computing power each year. Because these chips are essential for both consumer goods and military dominance, they have become the primary focus of the rivalry between the United States and China. China spends more on importing chips than it does on oil, and it is currently investing billions to break its dependence on Western technology.

The fragility of this system became clear during the global pandemic when minor disruptions in the supply chain caused factories to shut down worldwide. Unlike oil, which can be sourced from many different nations, the production of high-end computing power depends on a handful of specialized companies. A single natural disaster or a military conflict in the Taiwan Strait could paralyze the global economy. As the world moves further into the age of artificial intelligence, the struggle to control these silicon chips will determine the future balance of global power.
