The Chip Age: How Chips Shaped Our Past and Will Define Our Future Rakesh Kumar Icon (2026)

Few elements are as imperceptible to the public, but as essential to their lives, as semiconductors. The computer chip powers the machinery, systems and interfaces that people interact with daily. The average person will encounter a semiconductor dozens of times a day, whether it’s a small chip in your thermostat, on the motherboard of your computer or phone, or in your vehicle’s entertainment system.

Despite their tiny status, chips have become a very important business. They are the stuff of almost all modern anxiety: artificial intelligence, industrial sovereignty, military escalation, environmental stress, 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 eraattempts to explain how these fingernail-sized gadgets 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 story of materials, manufacturing, state subsidies, trade battles and small technical decisions that later change the world.

Kumar describes the geological feature that 380 million years ago made the town of Spruce Pine, North Carolina, the world’s leading source of high-purity quartz needed for chip-making crucibles. And it describes the fierce trade battles, tariffs and lawsuits of the 1980s against the “dumping” of goods in domestic markets between the United States and Japan that ultimately led to the decline of the Japanese memory chip industry.

Industrial history

The narrative is particularly strong when describing the early history of chip integration, when electronics moved from discrete components to circuits etched onto a single substrate. Kumar writes that institutions, not lone geniuses, drove chip development. However, it highlights the advances of engineer Jack Kilby of Texas Instruments in Dallas and physicist Robert Noyce of Fairchild Semiconductor: Kilby invented the first integrated circuit on a single block of germanium in 1958, and Noyce later discovered how to build a mass-producible chip that integrated all the components and their interconnections on a single block of silicon.

Innovative computer chip technology could help meet ‘monumental demand’ driven by AI

Kumar’s account of Acorn Computers, BBC Micro and the eventual birth of UK-based chip titan Arm is wonderful. In the late 1970s, British broadcaster BBC launched a computer literacy project and computer company Acorn won the contract to build BBC Micro, which became a hit in UK schools and homes. In planning its next computer, Acorn discovered that existing microprocessors were inadequate and partnered with the American electronics company VLSI Technology in 1983 to design its own chip: the Acorn RISC machine. This highly efficient chip caught the attention of American tech giant Apple for its Newton wearable device. To manage this collaboration, Acorn spun off its 12-person processor division in 1990 to form Advanced RISC Machines (now Arm), which pioneered the revolutionary and wildly successful model of licensing its chip designs rather than manufacturing them.

Similarly, Kumar’s sections on Japan’s rise to become a leading producer of memory chips, the 1986 Japan-US Semiconductor Agreement, South Korea’s rise through the dynamic random access memory market, and Taiwan’s foundry model are rife with reflections on the current chip hierarchy, showing how the current global race was crafted through political decisions, industrial bets, and ruthless trade pressure.

Concentrated market

Explaining semiconductors to a lay audience is no easy task, and Kumar does it admirably. The book is full of details that make the reader cringe: Taiwan Semiconductor Manufacturing Company in Hsinchu produces more than half of the world’s chips and more than 90% of the most advanced ones. Globally, more than one trillion chips are shipped each year, with a total value of nearly $700 billion, and annual sales could surpass $1 trillion by 2030.

Kumar also gives an idea of ​​the scale of the race for state subsidies to ensure chip supremacy: $52 billion from the United States, €43 billion ($48 billion) from Europe, $24.5 billion from Japan, $10 billion from India and more than $100 billion each from South Korea and China.

It also goes beyond the usual geopolitical debate and addresses the issues of environmental damage, labor, rare earth minerals, counterfeit components, and geopolitical dilemmas facing world leaders.
