Best Of: The Most Amazing — and Dangerous — Technology in the World

“We rarely think about chips, yet they’ve created the modern world,” writes the historian Chris Miller.

He’s not exaggerating. Semiconductors power everything from our phones and computers to cars, planes, advanced military equipment, and A.I. systems. Chips are the foundation of modern economic prosperity, military strength and geopolitical power.

This conversation with Chris Miller, author of “Chip WarThe Fight for the World’s Most Critical Technology, () ” was recorded back in April. But we wanted to reair it, because what Miller lays out in that book, and in this conversation, is essential to understanding where we are in 2023, and the faultlines that will shape the world ahead.

Because semiconductors have  one of the most concentrated supply chains of any technology today. One Taiwanese company, TSMC, produces around 90 percent of the most advanced chips. A single Dutch firm, ASML, produces all of the world’s EUV lithography machines, which are essential to produce leading-edge chips. The entire industry is built like this.

That doesn’t just make the chip supply chain vulnerable to external shocks; it also makes it easily weaponizable by the powers that control it. In 2022, the Biden administration banned exports of advanced chips — and the equipment needed to produce those chips — to China, and then further tightened those rules this October. In August 2022, President Biden signed into law the bipartisan CHIPS and Science Act, which includes a $52 billion investment to on-shore U.S. chip manufacturing. China has invested tens of billions of dollars over the past decade to build a domestic semiconductor industry of its own. Chips have become to the geopolitics of the 21st century what oil was to the geopolitics of the 20th.

In this conversation, Miller talks me through what semiconductors are, why they matter and how they are shaping everything from U.S.-China relations and the Russia-Ukraine war to the Biden policy agenda and the future of A.I.
