GoKawiilThe Chip Age: How Chips Shaped Our Past and Will Define Our Future Rakesh Kumar Icon (2026)
Few items are so imperceptible to the public, yet so essential to their lives, as the semiconductor. The computer chip powers the machinery, systems and interfaces that people interact with on a daily basis. The average person will encounter a semiconductor dozens of times a day, whether it’s a small chip in their thermostat, in their computer or phone’s motherboard or in their vehicle’s entertainment system.
Despite their diminutive status, chips have become a very big deal. They are the object through which almost every modern anxiety passes: artificial intelligence, industrial sovereignty, military escalation, environmental strain, supply-chain fragility and the future of scientific discovery.
How wealthy tech entrepreneurs seek to shape politics, culture and the future — and why we must resist
Rakesh Kumar, a computer engineer at the University of Illinois Urbana-Champaign, understands how important chips are. And in The Chip Age, he tries to explain how these fingernail-sized gizmos have become the material substrate of contemporary power.
At its best, the book is a reminder that the history of computing is not just the history of software, entrepreneurs and Californian myth-making. It is a history of materials, manufacturing, state subsidy, trade battles and small technical decisions that later change the world.
Kumar outlines the geological accident 380 million years ago that made the town of Spruce Pine, North Carolina, the world’s main source of the high-purity quartz needed for chip-manufacturing crucibles. And he describes the fierce 1980s trade battles, tariffs and lawsuits against the ‘dumping’ of goods into domestic markets between the United States and Japan that ultimately led to the decline of the Japanese memory-chip industry.
Industrial history
The account is particularly strong when describing the early history of chip integration, when electronics moved from discrete components to circuits etched on a single substrate. Kumar writes that institutions, not lone geniuses, pushed forward the development of chips. However, he notes the breakthroughs of engineer Jack Kilby at Texas Instruments in Dallas and physicist Robert Noyce at Fairchild Semiconductor: Kilby invented the first integrated circuit on a single block of germanium in 1958, and Noyce subsequently worked out how to build a mass-producible chip that integrated all of the components and their interconnections onto a single block of silicon.
