The Ezra Klein Show: The Most Amazing — and Dangerous — Technology in the World

New York Times Opinion New York Times Opinion 4/4/23 - Episode Page - 58m - PDF Transcript

I'm Ezra Klein, this is the Ezra Klein Show.

So you may have noticed at the beginning of the year that two themes are really dominating

the show. China and AI. And obviously that's not an accident. I'm not going to try to rank

order what matters most in the world, but these are two good contenders for the top

five at least. When I imagine the history books getting written of our era, it is very

hard for me not to imagine these being dominant themes. And these stories connect. They connect

in obvious ways. There's a geopolitics of who controls AI, a race between the US and

China to get the strongest and earliest AI capabilities, but they also connect in another,

more tangible way. They are both stories driven by semiconductors and who controls them.

In the same way that you couldn't understand geopolitics in the 20th century without understanding

oil and other forms of energy, where it was and who had it and who needed it and what

they would do to get it, you can't understand the major stories of the 21st century without

understanding semiconductors. Whoever controls semiconductors controls the future. And it

turns out for reasons I didn't really understand until I read Chris Miller's book, Chippor,

that semiconductors really can be controlled. So Chippor, which is just amazingly timed

given how deep it is, is a history of semiconductors as a technology, as an industry, and then

it traces the way they have and are shaping geopolitics. It was a Financial Times's business

book of the year in 2022 and having read it now, definitely going to be on my year-end

list of the most important books I read in 2023. And there's a lot more in the book

than I'm able to cover in the show. I really do recommend reading this one. But I do think

the show is one of the more important we're going to do and important for understanding

a lot of the other shows we're going to do, because this is getting in a material reality

that is easy to miss, but is going to shape so many of the big stories we're living through

in the coming years. As always, my email is reclinedshow at nytimes.com.

Chris Miller, welcome to the show.

Thanks for having me.

What timing on this book, man. I assume, when did you actually start it? Because I honestly

cannot imagine a better moment for it to have come out.

I started researching it around 2015, 2016. Didn't start writing until 2020 and finished

writing early 2022, just as the chip shortage was reaching its peak.

So let's talk a bit about why semiconductors end up mattering this much. You write that

we rarely think about chips, yet they've created the modern world. Justify that for

me.

Well, today, people like you and me can't live our lives without touching hundreds or thousands

of chips, just going about the course of our daily lives. We think of chips as being in

smartphones or being in PCs, but today, they're in almost any device with an on-off switch.

So a new car will have a thousand chips inside of it, your refrigerator, your microwave,

your dishwasher. All of our devices are full of chips that do computing, do sensing, increasingly

do communication. And so the modern economy just can't function without lots and lots

of chips.

I don't know if this will be a hard question or easy question for you, but like most people,

and particularly before I read the book, I have only the haziest idea of what a semiconductor

chip actually does. So you often describe it as providing the processing power of the

modern world. What is it actually doing?

So a chip is a piece of silicon with a lot of tiny circuits carved into it, and these

circuits are either completed or interrupted via device called a transistor, which is a

switch basically that turns them on or off. And when a circuit is on, it produces a one.

When it's off, it produces a zero. And all of the ones and zeros that undergird all of

software, all of data storage, it's just circuits turning on or off to produce the right digit.

And today, we have lots of digits we require because we store and process lots of data.

And so advanced semiconductors today have millions or often billions of these tiny circuits

etched into them that provide the ones and zeros that modern computing requires.

Tell me about that size. When you say you have billions of these circuits on a chip,

how small are we talking? How is that possible to be etching or really doing anything at

that scale?

Today, if you go to an Apple store, for example, and buy a new iPhone, just the primary chip

in an iPhone will have around 15 billion transistors on it. And so each one of these tiny switches

is smaller than the size of a virus. They're measured in a number of nanometers, which

is a billionth of a meter. And so these are the smallest devices that humans have ever

mass produced. And we produce more of them than we produced any other device in human

history.

Tell me a bit about how quickly we've been able to shrink the scale at which we're working

here and increase the density of the chips. I mean, these aren't a very old technology.

As you point out, Silicon Valley, which has not been around forever, gets its name from

the silicon of which these chips are made. So when this starts, what is a level of complexity?

When is that? And what is the process by which we get to today?

The first chips were invented in the late 1950s. They first became commercially available

in the early 1960s. And at the time, they would have had a handful of transistors on

them. And the rate at which we were able to pack more transistors onto a chip, which was

also the same as the rate that we were able to shrink transistors down to enable more

of them to fit on a piece of silicon, has increased exponentially. So there's been basically

a doubling of the number of transistors you can fit on a given size chip every two years

since the 1960s. And that's come to be known as Moore's Law, named after Gordon Moore,

who was one of the early engineers that created the industry and eventually went on to found

Intel. And what that's meant is that the chip industry has produced improvements that have

gone far beyond any other aspect of the economy. There's nowhere else in the economy we've

had exponential growth rates persist for not only years, but half a century.

Let's talk for a minute here about Moore's Law because there's a, I think a misleading

way in which it's called a law. It's not like the second law of thermodynamics or something.

It isn't a law. It's an early observation that ends up being weirdly predictive. So

what is he looking at, Gordon Moore, who actually recently just died? What is he looking at

when he makes that observation? And then why in your view, does it not just come true,

but come true beyond his own expectations for it?

So he made this observation in 1965, which was just seven years after the first chip

was invented. And he noticed that the number of transistors per chip was doubling every

year or two. And he predicted, given the technology that he saw being developed at the time, it

would last for at least another decade through 1975. And that proved true. But as that was

proven true, chips became more powerful, also cheaper, because you could get more computing

power with a smaller and smaller chip. And they found more use cases across the economy.

So the first chips were used primarily for defense systems. But as the cost of computing

power fell, it became possible to apply them to more and more uses, to corporate computers,

for example, then to pocket calculators, then to automobiles. And as the use cases proliferated,

the investment dollars going into further shrinking transistors and further packing

more computing power into chips also increased dramatically. And so there's been a sort of

virtuous cycle between the cost of computing declining and even more investment dollars

going into driving that down further, because people realize that there were a lot more

uses for computing than anyone really imagined at the time that Gordon Moore first coined

the concept of Moore's law.

Which direction does that causality run? Were there more uses for computing than anybody

imagined? Or are there more uses for computing than anybody imagined because such computing

is now possible?

You know, I think it's actually both in some ways. Gordon Moore himself wrote a couple

of essays looking into the future of computing. And at the time, he predicted devices like

what he called personal portable communications equipment, sort of like a smartphone, if you

will. He envisioned home computers that would be networked together, sort of like the internet.

So it was possible to envision some pretty futuristic uses. But I think even he was

shocked by just the diversity of applications of computing and the ways in which they transformed

society. He could predict portable communications devices, but I think even he was shocked by

the iPhone when it first emerged a half century later.

I want to key in on an example of what it has taken to keep Moore's law going for as

long as it has. Because I also think having this in people's minds is important for the

geopolitics and the policy that's going to come in this conversation. So you spend some

time that I would describe as somewhere between loving and odd, describing the development

of EUV lithography. So tell me that story in some detail. What is it and how did it

get from a hope to a reality?

One of the process steps in manufacturing chips is projecting a pattern onto the silicon,

a pattern that describes where the transistors will be. And at first, you could actually

do these patterns by hand because transistors were large enough to be carved out by hand.

But as they've become smaller, you need to project them using sort of like a microscope

backwards. Microscopes take optics to make something small like big, and we do the opposite

to make a big pattern projected in a very small form onto a chip. And for a long time,

the optics involved were pretty straightforward, and you could use visible light to project

the patterns and interact with chemicals in specific ways to carve transistors onto chips.

But as they've gotten smaller and smaller, the wavelength of visible light has gotten

far too broad to actually carve transistors in the way that we want. So visible light has

a wavelength of several hundred nanometers, depending on the color, whereas the transistors

on your smartphone are far smaller than that in dimension. And so around three decades ago

in the early 1990s, scientists began developing a new type of lithography more precise using

smaller wavelength light in the ultraviolet spectrum. And this was necessary to get the

precision, but it was also extraordinarily complex to produce. And so today, there's

just one company that is capable of producing the machines that are capable of providing

this light at the scale and with the precision necessary. And these machines are the most

complex machines humans have ever made. They require one of the most powerful lasers that

has ever been deployed in a commercial device. They have an explosion happening inside of

them at 40 or 50 times hotter than the surface of the sun. And because of all this precision,

they require $150 million per machine to produce, require multiple airplanes to move. They're

sort of extraordinary accomplishments of human engineering, but also wildly complex. And

that complexity has made modern shipmaking more and more difficult. But that's the only

way to get the precision that we require.

They also, from the way you tell the story, represent remarkable accomplishments of supply

chain management and to some degree globalization. So it's a Dutch company making these systems,

but they are a company that does a lot of sourcing. They don't just make the system

in a factory somewhere. You talk about just the laser needed for the system, which comes

from another company, which is called a slightly weirdly Trump with a PNF. And you say that

the laser itself requires exactly 457,329 component parts, many of which need to be

made by different players. So you're dealing with the sourcing when you then scale up to

the entire machine of a number of parts that seems almost unimaginable.

Yeah, that's right. And the engineering doesn't simply happen on the machine itself. The supply

chain itself is an engineered process carefully sculpted to select the suppliers that this

company knows they can trust, suppliers that they know they can deliver on time, and suppliers

that they know they can deliver high quality products. Because if you think, for example,

of what it takes to keep a machine with hundreds of thousands of component parts operational,

the mean time to failure of each of those parts has to be measured in the decades or

else the machine never works. So that level of precision and reliability has been extraordinarily

difficult to produce. And it's why there's just one company in the world that is capable

of producing them.

So something you trace in your story is that for some time now, chips have been this hidden

geopolitical force. You tell it in part through the changes in military power and what got

called in the US, the offset strategy beginning sort of late in Vietnam as that war was failing.

But then building into something that created an era of quite profound American military

dominance, which was then noticed by everybody else and others are trying to match. Can you

talk a bit about how these ended up changing, not just warfare, but America's military

position vis-a-vis competitors?

Yeah, the US military was actually one of the early drivers of innovation in semiconductors.

The first chips that were created were created for guidance computers in both space systems

and in missile systems. And the Pentagon funded a lot of the early research in semiconductors

and still is a major funder of a lot of cutting edge research today. The military was interested

in semiconductors because it wanted to miniaturize computing power to distribute it across battlefields.

If you think back to the earliest computers in the 1940s or 1950s, they were the size

of rooms far too large to be deployed in systems in the field. And so the military wanted to

find a miniaturization technique and chips were the answer. And over the course of the

Cold War, the US military deployed chips in all manner of devices and in airplanes and

satellites and missile guidance systems. And a lot of the precision that we take for granted

today in military systems, the idea that you could launch a missile and have it hit a target

hundreds of miles away with pretty close to perfect accuracy, is only possible because

of lots and lots of semiconductors, chips in the missile that guide it, chips in the

satellites that send signals as it identifies its location over the course of its flight,

chips in the sensors that are collecting, targeting information, chips in the communication

systems that are distributing this data across the battlefield. And so the US military was

actually the first institution to show the ways that the distribution of computing and

sensing that chips provide can transform how organizations work and can provide extraordinary

value in terms of networking different devices together. And so that, that was important

both in explaining why the US jumped ahead in military power during the late Cold War,

but it also provided an example for the rest of the world to see not only how militaries

but how all institutions could take advantage of semiconductors to provide new types of

capabilities they previously hadn't imagined. A point you make towards the end of the book

is that one reason Russia has struggled so badly in its effort to invade Ukraine is

that they're using a lot of pretty technologically rudimentary military hardware that a surprising

number of their munitions we're seeing are unguided. They're not sort of modern smart

weapons. A lot of what we're giving and Europe is giving to Ukraine are more precision oriented

like the javelin missiles that people have probably heard about. Can you talk a bit about

how that's played out into the balance of military power and force there now as we speak?

It's been hugely important in a number of different ways, partly as you say, because

the Russians just have less sophisticated equipment than we're able to give to the Ukrainians.

Partly because even in the relatively sophisticated equipment that the Russians have, they're

using pirated or smuggled in version of Western microelectronics, Western chips, which are

not custom-made for their defense systems in which Russia's never sure whether they're

getting counterfeit versions or the real thing. So even when Russia's able to acquire

more advanced Western chips from abroad, there's all sorts of issues it creates in their supply

chain and their systems integration as a result. But then perhaps the most important is that

Ukraine has benefited from all the intelligence gathering and processing capabilities that

the US military has, which is largely today a question of signals intelligence, of satellite

photos, of radio signals being gathered, decoded, processed. And this is intensely reliant

on computing power, both to understand what's being said and then to dissect signal from

noise and give the Ukrainians the useful information. So when you think about a Heimar's rocket,

for example, the easy part of the computing is actually guiding the rocket towards its

target. The hard part is identifying where the targets are in a rapid enough fashion

so that the target hasn't moved by the time you want to fire it. And that is thanks to

US intelligence gathering, which today is more dependent than ever on semiconductors.

The next turn of this wheel, both militarily and more broadly economically, seems to be

different forms of machine learning of artificial intelligence. And that's a story we tend to

talk about in terms of data. You'll hear things like data is a new oil story we sometimes

talk about in terms of training algorithms and theories like deep learning. And it's

a story that is very much grounded in semiconductors that if you're talking about training next

generation artificial intelligence systems, you're talking about these chips. So can you

talk a bit about the interrelationship there and what kinds of chips have become crucial

for AI and the way that has also begun to play into different major countries' conceptions

of what you need for geopolitical primacy?

If you want to train a sophisticated AI system, you do need lots of data to train it on. But

that data is only possible to process and to remember by deploying lots of advanced

chips. And so today, for training AI systems, there's a type of a chip called a GPU, a graphics

processor unit, which was actually originally invented for computer graphics. But the math

that the chip was capable of processing turned out to be useful for training as well. And

so today, there's just a couple of companies that produce or design the most advanced AI

chips. And in particular, a company called NVIDIA based in California produces the majority

of the chips used for AI training in the world. And NVIDIA manufactures all of its leading

chips at one company, TSMC in Taiwan. So underneath all of the AI training happening around the

world, whether in the US or in Europe or in China, are chips produced by just a couple

of companies. And that produces a level of political influence that the US in particular

has tried to wield in recent years.

So you brought up Taiwan here, which is a helpful bridge for me because you spend a lot

of the book focused on this one Taiwanese firm, TSMC, which produces 90% of the world's

most advanced chips, 90%. And let's start here by talking about why. Why does TSMC have

this hammerlock over the most advanced chips? I think the number you have in the book is

they're producing or Taiwan is producing more than a third of new computing power every year.

How?

So there are only three companies in the world that are anywhere close to being able to produce

cutting edge processor chips, TSMC in Taiwan, Samsung in South Korea and Intel in the United

States. And the complexity and the cost involved of cutting edge production means that these

three firms will be the only three firms close to the cutting edge for at least the next

half decade, probably longer. So there's just extraordinary concentration in the industry

when you get close to the leading edge because of the expense and the sophisticated technology

involved. TSMC is the leader of those three because when it was founded in 1987, it was

founded with a unique business model. Morris Chang, the individual who founded the company,

had a vision of not designing any chips, only manufacturing them. And before that point,

almost all chip firms both designed chips and manufactured them in-house. But Morris

Chang realized at the time that the complexity of both design and manufacturing was growing

in a way that would require firms to specialize. And so he set up TSMC, promising never to

design any chips, but only to manufacture them. And he was able as a result to serve

many different customers. Today, he manufactures chips for Apple, for Nvidia, for AMD, for

Qualcomm, many of the biggest chip design firms. But he doesn't compete with any of

them because TSMC doesn't do any design itself. And so TSMC is now the world's largest chip

maker. Because it's the world's largest chip maker, it has reaped extraordinary economies

of scale, letting it drive down costs. And what's most important is that there's a pretty

clear relationship between the number of chips you produce and your ability to hone your

technology over time because you get data for each chip you develop. And so TSMC has

been able to develop the most advanced manufacturing technologies as a result of its scale. And

so today, TSMC produces, as you said, 90% of the most advanced processors, the types

of processors that go into smartphones, PCs, data centers. The other 10% are produced by

Samsung of South Korea. And Intel right now is a generation or two behind what either

of those firms are capable of producing.

Tell me about the political economy of TSMC's birth and rise. Because when you tell a story

of Intel, you have a bunch of scrappy young weirdos, they're one firm and then another

and then they go to another or found another, I should say. And it's a very Silicon Valley

story. And TSMC isn't like that. It's a sort of public-private hybrid institution. So

tell me a bit of their story.

So TSMC was founded in 1987 by Morris Chang, who at the time had been a tech executive at

Texas Instruments for almost three decades. He was passed over for the CEO job. And so

I was looking for something else to do. And he was approached by the government of Taiwan,

which wanted to create a chip industry that was moving up the value chain. At that time,

Taiwan was a producer of relatively low value electronics and wanted to produce higher value

semiconductors. And the government gave Morris Chang a sort of a blank check to set up a

new firm. It provided half the capital for the company and got a number of Taiwanese business

people to invest another 25% in the firm and was very supportive of the company's early

development. And so in some ways, it was very much a public-private partnership. But in

other ways, the company had to survive from day one by selling to the international market

because the domestic market in Taiwan was far too small to sustain a semiconductor industry.

So the firm had to sink or swim by selling manufacturing services to largely U.S. firms

from day one. And so in a lot of ways, TSMC has grown up alongside a new set of semiconductor

design firms that previously didn't exist because there weren't companies like TSMC

that manufactured chips but have been able to thrive because they haven't had to worry

about manufacturing. They've outsourced all that to TSMC and have designed chips instead.

And so companies like Apple, which manufactures all of its key chips at TSMC or NVIDIA, the

company that makes the chips that train AI systems, they've never had to build their

own manufacturing facilities because TSMC handles all of the cost and understands all

the manufacturing technology so they don't have to worry about it. And that's been a

very effective business model both for TSMC but also for the U.S. chip design firms that

have always been TSMC's largest customers.

Let's say I designed a computer virus tomorrow. What it did is it simply targeted every TSMC

location worldwide and knocked out all their electronics. So effectively, the company ceases

to in any way function tomorrow. And there's no real way to get it back online. What happens

to the global economy after that?

We'd face an economic crisis globally akin to the disruptions that we saw during the

Great Depression. It's not just tech devices like smartphones or PCs that would be catastrophically

disrupted. And we certainly struggled to build a cell phone anywhere in the world for the

next year or so. We'd have PC production fall easily by a third, maybe by half. Data

center rollouts would grind to a halt to be hard to build a cell phone tower anywhere

in the world because cell phone towers are just big metal poles with lots of chips on

top of them. But it's also all other manufactured goods, so dishwashers and microwaves and automobiles.

They don't necessarily need the most advanced chips, but Taiwan doesn't only produce the

most advanced chips. They produce lots of less advanced chips as well. And the semiconductor

shortage of the last couple of years illustrated that it's not only the tech sector that's

reliant on chips. It's companies like car firms, too. During the chip shortage of 2020,

2021, the world's car industry faced an estimated $200 billion worth of losses because they

couldn't sell as many cars as they'd hoped because they couldn't get all the chips that

they needed. And there's lots of different countries that produce chips in cars. But

if you think of a typical new car having 1,000 chips inside and figure 10, 20, 30% of those

chips generally come from Taiwan, replacing those would be an extraordinary challenge.

And we'd see huge disruptions across the entire world's manufacturing sectors. And final

point is that it's not just the U.S. that's reliant on chips from Taiwan. It's everyone.

It's Europe. It's Japan. It's China. The entire world's manufacturing sector requires TSMC's

chips.

And so there's TSMC's chips, but we also mentioned the Dutch manufacturer, lithography.

This is a place you say where the oil metaphor misleads, but probably not in the direction

that people would think. If I say chips like the new oil, you might think, that's great

because we know that there's only oil in so many places and chips all you need is a manufacturing

facility. But you write that unlike oil, which can be bought from many countries, our production

of computing power depends fundamentally on a series of choke points, tools, chemicals

and software that are often produced by a handful of companies and sometimes only one.

So beyond TSMC, tell me a bit about the level of vulnerability and choke points here.

Let every step in the production process of an advanced semiconductor, whether it's the

software tools that are used to design them, the machine tools like the lithography systems

that are used to manufacture them, the actual manufacturing often at TSMC, there's usually

just a couple of companies that are capable of producing the most cutting edge capabilities.

And that's just because it's very expensive and very hard to do so. And specialization

has been critical to the industry. That's why we're able to produce semiconductors

with 15 billion transistors on them at a price that all of us can afford. But it's also created

risks and vulnerabilities, because in some cases, there's only a single source for certain

types of materials or tools. And that creates single points of potential failure. And the

world I think has done a reasonable job of managing many of these risks. We've made an

error somewhat in putting a lot of our chip making capacity in seismically active zones

like Silicon Valley in Japan and Taiwan. But actually, we've been able to manage that risk

somewhat too. But obviously, the biggest risk hanging over the industry today is the concentration

in the Taiwan Straits where compared to five or 10 years ago, there's far more concern

that something might go wrong. And if it does, we're guaranteed to get vast disruptions in

chip supply.

So this to me has been a very undernoticed part of America's commitment to Taiwan and

America's concern about China potentially taking Taiwan. I think most people hear this

and they think, in reality, why would we really care that much about Taiwan? I mean, we don't

want China becoming territorially expansionist. Taiwan is our friend. But why do we really

like real politic care about Taiwan? And one reason seems to be that you lose Taiwan and

you lose semiconductor industry that Taiwan is a point of vulnerability for the entire

world. And that really raises the stakes on this. So can you talk a bit about the ways

in which the geopolitics around Taiwan have become merged with the dependence we all have

on semiconductors?

If you ask the Taiwanese government, what they'll tell you is that Taiwan's position

in the chip industry creates what they call the silicon shield. The idea being that it

would be too expensive for anyone to disrupt the chip supply coming out of Taiwan and therefore

no one will be willing to do so. And I think that might be true, but I'm not sure about

it. It's also the case that Taiwan's chip production guarantees that the U.S. is interested

in ensuring ongoing good relations between the U.S. and Taiwan and peace between China

and Taiwan. And that dynamic is certainly true as well. I also think it's probably an oversimplification

to argue that semiconductors are the primary reason or a primary reason that either China

or the U.S. are interested in Taiwan, because of course both countries have been involved

in the Taiwan question since 1949 before the first chips were invented. And so in some

ways we have semiconductors sitting at the center of the competition in the Asia region

between the U.S. and China. But in other ways, the competition is largely driven by political

and military factors that intersect with chips but are far from guaranteed to ensure

that their supply is uninterrupted. And so I do worry that actually chips don't provide

a deterrence against conflict or don't guarantee that conflict won't happen, but actually they

would be the first disruption and the first most dramatic disruption that we face if in

case conflict does materialize. So as a result, I finished my study of the chip industry in

the ways it intersects with the China-U.S. relationship, much more worried, thinking

that perhaps it's stabilizing, but perhaps it's not. And if it's not stabilizing, we're

in a very vulnerable position.

Tell me a bit about the chip's question from China's perspective. You make the point that

China now spends more money importing chips and it spends importing oil, which is a striking

fact. How does this look to them?

Well, for China's leaders, it's an extraordinary vulnerability, both because they're well aware

that in case of a crisis, they're likely to lose access to the most advanced chips produced

in Taiwan, also in Korea, Japan, and the United States. They also see it as an economic vulnerability

because for China's electronics industry, moving up the value chain requires producing

semiconductors. If you look, for example, at a smartphone, most of the world's smartphones

are assembled in China, but most of the high value components of a smartphone are semiconductors.

And so even in Chinese branded smartphones assembled in China, most of the bill of materials

ends up going to Taiwanese, to Japanese, Korean firms because they're producing the chips

inside of these phones. And so if China wants to progress technologically, economically,

they believe they've got to domesticate production of semiconductors. And the challenge they

face is that the Chinese government has been struggling to do so. They've been spending

billions of dollars a year since 2014 to try to produce cutting-edge chips domestically.

They've made some progress in a number of spheres, but in aggregate, they still remain fundamentally

dependent, not only on importing chips, but also the chips that China does produce domestically

are produced almost exclusively using imported machine tools like the lithography tools that

I described. And so although China is a manufacturing powerhouse, it's actually a small player when

it comes to the production of semiconductors, especially when we're talking about cutting-edge

semiconductors.

Can you talk about the idea of weaponized interdependence?

Well, this is a phrase that was popularized by two political scientists several years

ago who noted that in theory, many people had thought that interdependence would produce

peace. It would increase the incentive for political actors to cooperate because they

had economic incentives to do so. But in reality, what we were seeing in the world was that

interdependence was not only relevant in terms of building bridges between countries, but

it was also a sphere of competition. In that countries, we're using their privileged position

in certain networks to try to cut out or to punish their competitors. And we've seen

this in cyber networks, for example, where the US has a unique capability to conduct

cyber espionage because a lot of the world's key data centers and cables transfer through

the US. We see it in financial networks with the US also has a unique position. We also

see it increasingly in semiconductors because the US sits at the center of many of the world's

semiconductor supply chains and the other key nodes are close US allies like Taiwan or

like Japan. And what that's meant is that the US government over the past 10 years or

so has been able to surgically cut China out of certain parts of the chip industry while

keeping China dependent on many other types of chips. And so whether it's cutting edge

tools, cutting edge software or certain types of chips like the chips used to train AI systems,

the US is able to say China can't have access and it's able to force the world's chip firms

to basically comply.

I think the political history of our policies here is interesting. There's a pretty sharp

discontinuity between Obama and Trump and quite a bit of continuity on this from Trump

to Biden. So first can we talk about the Obama to Trump change? What is the Obama administration's

perspective on semiconductor competition dominance particularly around China? What

do they do about it? And then how does the Trump administration change that? What do they

actually do differently than the Obama administration had done?

I think the Obama administration in their final year or two in office was beginning to actually

trend in the direction that the Trump administration eventually took things, but it certainly was

the Trump administration that was first willing to disrupt supply chains, first willing to

take costly measures, and first willing to characterize tech competition as more zero

sum than positive sum when it came to China. And so as a result of this new worldview,

the Trump administration took a variety of steps in the semiconductor space to cut off

China and to punish China for efforts to steal technology from Western firms. So for example,

the U.S. put out of business a company called Fujian Jinhua, which had been found to be

stealing technology from a U.S. chip maker called Micron by banning this firm from accessing

machine tools that are made in the United States without which it's impossible to produce

semiconductors. And so overnight this company went out of business because it couldn't get

the requisite tools. And this was a really dramatic step. It was very different from

the prior U.S. strategy of starting WTO cases, for example, or trying legal measures. This

was just an executive measure that said this Chinese firm can't access the tools anymore.

And that began to illustrate the power that the U.S. regulators had to determine who got

access to chips and chip making tools and who didn't. Another example is Huawei, the

Chinese telecoms firm, the U.S. banned Huawei from accessing certain types of chips and

forced Huawei to divest entire business lines. And that again illustrated that even China's

leading tech firms were producing technology that required foreign semiconductors, U.S.,

Taiwanese, Japanese, Korean inside. And U.S. policy makers, I think, were impressed and

in some ways even surprised by the power that this demonstrated. And that explains why the

Biden administration has somewhat different ways, but in a large sense carried on the

weaponization of semiconductor supply chains that the Trump administration started.

Let's talk about the Fujian Jinwa story in more detail because the way it sounds there,

it's like me in America comes in and puts out the business is Chinese company. But you

told story in some detail in your book. And what was happening before that, which was

in some ways, I don't want to exactly call it normal, but a common complaint of American

businesses dealing with China, which then the Trump administration decides they're not

going to stand for anymore. It is pretty interesting at getting, I think, at the other side of

the frustrations here. So can you walk through that a little bit more slowly?

So there's a U.S. firm called Micron, which produces memory chips and had a facility in

Taiwan actually. And a number of the engineers there began stealing internal documents with

the aim of quitting the firm and then bringing this inside information to the Chinese firm,

Fujian Jinwa, which was trying to ramp up production of the exact same type of chips

in China. And this is a type of chip that Chinese firms have never produced at the cutting

edge before. And this was quickly discovered by the company. Legal cases were brought.

There's very clear evidence, for example, of some of the employees in question typing

into their computers, delete Google search records, for example, to try to cover their

tracks. So there wasn't much ambiguity as to what top flight espionage, how to delete

your records.

Exactly. So there wasn't much ambiguity as to what was going on. And I think in prior

instances, this would have produced a legal dispute or diplomatic discussions. But the

legal mechanism simply didn't work. Micron brought a suit against Fujian Jinwa for stealing

intellectual property in China. But in Chinese courts, they actually ruled in favor of the

Chinese company against Micron, alleging that Micron had stolen the Chinese company's

intellectual property, which was, of course, a bogus ruling. But for Micron, China was

a critical market because China is the world's largest consumer of chips. And so getting

locked out of the Chinese market was a real risk for any chip firm. And it had made them

all hesitant to actually take on Chinese companies or the Chinese government when they faced

legal issues.

And the Trump administration saw this, believed that the previous strategy hadn't really

worked, hadn't changed China's behavior. And so had real little faith in any sort of legal

or diplomatic mechanism and said, we're going to put Fujian Jinwa out of business. And via

executive order, that's exactly what they did.

Do you think they were right?

I think they were right. I think that the track record had been that the legal mechanisms

had failed to address intellectual property theft. The fact that Chinese courts, despite

all the evidence had intervened on behalf of the Chinese firm, suggested that there was

really not much hope for legal mechanisms working. And the alternative was just to let

intellectual property that stuff like this keep happening, which doesn't seem to me like

a very viable alternative strategy.

So you can look at that case as a case of reprisal. We are going to punish you for doing

something wrong. And I think that it's a pretty clear cut case that something was being done

wrong by China repeatedly there.

Then you have Huawei, which is more about not wanting a Chinese company to build the

backbone of 5G internet and a lot of telecommunications fears that on the one hand there were security

risks that couldn't be addressed. And even if you could address that, that the dependence

on China was a kind of dependence we didn't want. And you can tell me if you think that's

an unfair characterization of it.

And then under Biden, there's another pretty big step up in these export controls on semiconductor

chips, which isn't just that we don't want to be dependent on you, but we actually want

to slow down your advance. We don't want you to have a semiconductor industry moving towards

equality with ours to say nothing of getting beyond ours. And we're going to weaponize

the supply chain to stop that from happening.

So can you talk a bit about that change to the Biden administration? Where did they go

that the Trump administration had not and why?

Well, as you have this escalation in US policy, you also have technology trends developing

in important ways that I think are key to understand. And the key shift here is the

training of artificial intelligence systems and the realization that training the most

advanced AI systems will increasingly require vast volumes of data that grow every single

year and therefore cutting edge chips. And so the Biden administration, I think, not

only had the concerns of the Trump administration when it came to IP theft or came to China's

role in telecom networks, but it was also looking at the future of AI and realizing

that it was going to be US chips that were going to be training the world's AI systems

over the subsequent decade and that AI systems are going to be even more powerful than people

had thought five or 10 years earlier. And so it was hard to predict for them how AI systems

would develop, but it seemed inconceivable that they wouldn't have, in addition to transformative

economic ramifications, also vast military and intelligence uses. And so given the tremendous

growth in AI plus the reality that training AI required US hardware, to them, I think

this looked like a risky moment, actually. If AI was unleashed and the chips that could

train AI were unleashed to the entire world, the results would be unpredictable. And so

I think in addition to the Trump administration's concerns, they were also looking at these

trends saying, we want to have some control over how US chips are used to train AI systems.

And that explains why last year, they rolled out two different prongs of a new export control

regime, the first which limited the transfer of certain AI training chips to China, made

it illegal to transfer NVIDIA GPUs above a certain threshold to China, and then also

said because these chips are so important, we want to make sure that China can't produce

them domestically. And so to do that restricted the transfer of any advanced machine tools

to China as well. And so this is a very zero sum view of the world that takes all of the

national security advisor outlined when these controls were announced. But it's a zero sum

view of the world that I think is informed by a lot of concern and uncertainty about

how AI systems will be deployed by other countries for military uses and for intelligence gathering.

These export rules were announced six months ago. What has their effect been so far in

China?

We know the effect of the machine tool restrictions, which have caused pretty substantial challenges

for Chinese firms at the cutting edge or close to the cutting edge in production because

all of China's leading edge production has required tools from the US, from Japan, from

the Netherlands, and those three countries are all implementing roughly similar controls

right now. It's harder to say what the impact of the ban on AI chips has been because China

still has a large stock of existing AI chips that had imported before the ban was in place.

And so these controls won't begin to have an impact for a couple of years when the rest

of the world builds next generation data centers or the generation after that and China's unable

to. And at that point, we will begin, I think, to see some differential open up in terms

of the ease of training AI systems in the US or in Europe or in Japan and the comparative

difficulty of doing so with less advanced chips in China.

The other side of the Biden administration's thinking on semiconductors has been to build

or rebuild American semiconductor manufacturing. So tell me about the Chips and Sciences Act.

What does it want? What is it trying to achieve? And what does it actually do?

So there's two major facets of the Chips and Sciences Act. The first puts around $10 billion

to R&D spending, which is intended to increase innovation in the chip industry and keep the

US at the cutting edge in many different spheres. The second is to provide incentives for firms

that open up new manufacturing facilities in the US. And here the goal is to address the fact that

it's more expensive to build chip making facilities in the US than it is abroad. 20 or so percent

more expensive than in Taiwan or in Korea, which over the last several decades has been one of

several factors encouraging companies to build more facilities in other countries rather than

in the US. And so the $39 billion in incentives is intended to help companies defray the cost

differential and thereby encourage them to build more capacity in the US.

Do you think it is likely to succeed in doing that?

Well, I think there's no doubt that it will succeed in the short run. If you pay companies to

build factories, they're going to build them. That's straightforward. I think the harder

challenge is to have an impact after we've spent these first $39 billion of subsidies.

I'm skeptical that there will be a second round of Chips Act spending to defer cost

differentials in the future. And so I think the real challenge is to say, can we get the

chip industry investing more in the US over the long run even after we're no longer subsidizing

them? And I hope the answer is yes, because I don't think subsidies indefinitely into the future

are likely, but it's going to be much more challenging because a lot of the drivers of the

cost differential still exist, that labor costs are higher in the US. It's more difficult because

of environmental permits, for example, to build facilities in the US. And so we've got to produce

an environment that does address some of the cost differential, but also make sure we've got

other assets, more productive workers, for example, or closer integration between

chips and the software firms that they're serving that make up for the cost differential. And that's

ambitious goal. I think it's a worthwhile goal, but it's far from guaranteed that we're going to

achieve it. I've been spending a lot of time looking at the Chips Act for a big story that I

guess will probably be out by the time this publishes. And you and I spoke for this piece.

And something that looking through the Notice of Funding Opportunity, which is the

publication that explains how the US government is going to evaluate applications for this money.

And I think I'm prepared to say now, having spent more time with the document and talking to people

that this does not lower the cost differential. It is subsidies and it has a lot of, I think,

good ideas. But aside from funding R&D to try to create innovative breakthroughs,

it doesn't lower the cost of what it takes to build or operate fabs or labor or through immigration,

bringing in more technicians. It really just doesn't do much to change what it costs to run

one of these in America. And in some cases, very arguably, will make it higher. They add on a lot

of standards. People have talked a lot about insisting that there's high quality childcare in

the fabs. But even beyond that, there's just a lot of language about creating pathways for

marginalized workers and trying to increase the representation of women in the construction

industry. And a lot of these ideas might be good ideas. But if you start from the perspective that

US chip manufacturing fell behind, because it's very costly to build and operate factories here,

it is very, very, very hard for me to look at this document and say what they are trying to

address is a cost differential. They're subsidizing on one side. They're adding a certain number of

regulations and standards on the other. But if you're starting from a place where you're already

non-competitive on cost, I mean, I'm curious if you think I'm being too harsh on this. It's just

knowing a little bit more now about what has been the problem for American semiconductor

manufacturing. It doesn't really look like it has a solution to that problem.

Well, I think I would say a couple things in response. I think you're right that in

any program like this, there's a risk that it loses focus and that multiple different political

interest groups manage to make an imprint on it. And I think keeping focus on the cost differential

is going to be a key determinant of success or failure in the long run. I think if you look at

what the Commerce Department has said about a lot of the preferences around childcare,

for example, or around profit sharing that have been controversial, I think a lot of these end up

being preferences rather than requirements. And the Commerce Department, I think, has signaled

a willingness to be flexible on some of them. So we'll have to see how exactly they're implemented

and how firms decide to deal with them. I think on the permitting question, which I think is really

quite important, this is a tricky issue because it's not just about the federal government. It's

also about state and local governments. And so I know the Commerce Department is aware of the

importance of this issue, but it's also about making sure that the Arizona state government

and the Portland, Oregon City Council all agree that they're going to approve permits rapidly

rather than slow them down because of NIMBYism concerns. And this is a challenge in Taiwan.

TSMC is the island's most prestigious employer. It's the country's largest exporter. And so when

it has a request, its request is quickly granted. Whereas in the US, semiconductors are one important

industry among many. And so they just get less political priority as a result. And when they

face problems, they're solved less quickly for that reason. And so I think we still have a lot

more work to do, as you say, to make sure that we're actually taking steps that are addressing

the cost differential issues, both at the federal level, but also a lot at state and local levels.

And one thing I should say on this is when I spoke with Secretary Gina Armando, who runs commerce,

and when we talked about the environmental permitting and talked about the immigration

side, she said very clearly on the record, and it'll be in my piece, she would love that. She

would love Congress to come to her and do streamlined environmental permitting. She would

love Congress to come to her and work with her on easing immigration status for semiconductor

technicians. And she also said that she has made clear to governors that if they want a FAB,

that a grant application from a company where they've partnered with the governor or the mayors

or whatever to have permitting sped through will affect what commerce does. So if you're a governor

and you want this to happen in your state and you're able to give a company assurances that

they can take the commerce that it will and that you will have this the speedway, they will take

that into account. That gets me to one of my final questions here because I know we're running quite

out of time, which is when I read the history of the semiconductor industry in your book,

what it seems to me was one of the single most effective things we did was have a fairly open

immigration policy during a bunch of these periods that a lot of the industry has its roots in high

skilled immigrants to this country, particularly coming out of World War II. And it raises a

question as to whether or not one of the best things we can do for this industry and others is

actually high skilled immigration or targeted immigration because labor, is it such a shortage

in sort of skilled semiconductor manufacturing in America? How do you just think about immigration

as a technological competitiveness policy? Well, I think that's right. And if you look at

the individuals who founded the chip industry in the U.S., a disproportionate number of them were

foreign born, whether it's Andy Grove, the longtime CEO of Intel, born in Hungary, or Morris Chang,

who I mentioned, who built up chip making in Texas Instruments before he moved to Taiwan. He was

born in mainland China. You can go through a lot of the key CEOs and founders of the early

chip firms or the CEOs of today's biggest U.S. chip firms, and you'll find a disproportionate

number of immigrants there as well. So I think Secretary Armando is right that we ought to

have more pathways to have firms bring in the talented engineers that they need. The fact that

the industry has a really internationalized supply chain today allows a lot of efficiency. But

from the U.S. perspective, it would be even better to have a less internationalized supply chain if

more of those people could move to the U.S. and many of them would like to. They just can't get

the visas or the work permits that they need. I think that is a good place to end.

Always a final question. What are three books you'd recommend to the audience?

Well, I'd start with The World for Sale, which is an extraordinary account of commodity traders

who play an unseen role in the middle of the networks that deliver oil and minerals and metals

that we require. It's sort of an eye-opening view as to how all the world's raw materials get shipped

around the world. A second book I'd recommend, which picks up on a lot of the discussions we've

had about networks, is a book called Nexus by Jonathan Winkler, which is a study of telegraph

cables during the early 20th century. And what's striking about it is the extent to which all of

the world's governments saw telegraph cables as not only economically important, but also important

for military and intelligence uses. And when I think about Huawei today, I think back to the

telegraph cables debates of 100 years ago. And in some ways, not much has changed. And then a

third book, which was published last year, which I strongly recommend, is a book on decision-making

in China called Prestige, Manipulation, and Coercion, which is an extraordinary account of

high politics in China over the last half century that illustrates with just a really exceptional

archival documentation how Chinese politics has shifted in the key drivers in it. And so

in my efforts to understand Chinese decision-making around semiconductors, I found

the framework that he set out very, very useful to understand how it is that Chinese leaders

make decisions. Chris Miller, thank you very much. Thank you.

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

He’s not exaggerating. Semiconductors don’t just power our phones and computers; they also enable our cars, planes and home appliances to function. They are essential to everything from developing advanced military equipment to training artificial intelligence systems. Chips are the foundation of modern economic prosperity, military strength and geopolitical power.

But semiconductors are also part of one of the most concentrated supply chains of any technology today. One Taiwanese company, TSMC, produces 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 October, the Biden administration banned exports of advanced chips — and the equipment needed to produce those chips — to China. In August, 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.

There is no better or more timely explanation of the semiconductor industry — and the geopolitics that have formed around them — than Miller’s new book, “Chip War: The Fight for the World’s Most Critical Technology.” So I asked him on the show to talk 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.
