☀️ My chat (+transcript) with economist Noah Smith on technological progress

Faster, Please! — The Podcast #59
1

Some signs of tech progress are obvious: the moon landing, the internet, the smartphone, and now generative AI. For most of us who live in rich countries, improvements to our day-to-day lives seem to come gradually. We might (might), then, forgive some of those who claim that our society has not progressed, that our lives have not improved, and that a tech-optimist outlook is even naïve.

Today on Faster, Please! — The Podcast, I talk with economist Noah Smith about pushing the limits in areas like energy technology, how geopolitical threats spur innovation, and why a more fragmented industrial policy might actually be an advantage.

Smith is the author of the popular Noahpinion Substack. He was previously an assistant finance professor at Stony Brook University and an economics columnist for Bloomberg Opinion.

Recognizing progress (1:43)

Pethokoukis: Noah, welcome to the podcast.

Smith: Great to be here!

Not to talk about other podcast guests, but I will very briefly — Last year I did one with Marc Andreessen and I asked him just how tech optimistic he was, and he said, “I'm not sure I'm an optimist at all,” that the most reasonable expectation is to expect the future to be like the past, where we have a problem building things in the real world, that some of our best ideas don't necessarily become everything they could be, and I think a perfectly reasonable baseline forecast is that, for all our talk about optimism, and “let's go,” and “let's accelerate,” that none of that happens. Does that sound reasonable to you or are you more optimistic?

I'm optimistic. You know, a few years ago we didn't have mRNA vaccines. Now we do. And now we have a magical weight loss drug that will not only make you lose weight, but will solve half your other health problems for reasons we don't even understand yet.

So much inflammation.

Right. We didn't even have that a few years ago. That did not exist. If you told someone that would exist, they would laugh at you. A magic pill that not only makes you thin, but also just solves all these other health issues: They would laugh at you, Scott Alexander would laugh at you, everyone would laugh at you. Now it's real. That's cool.

If you had told someone a few years ago that batteries would be as insanely cheap as they are, they would've been like, “What? No. There's all these reasons why they can't be,” but none of those reasons were true. I remember because they did actually say that, and then batteries got insanely cheap, to the point where now Texas is adding ridiculous amounts of batteries for grid storage. Did I predict that was going to happen? No, that surprised me on the upside. The forecasters keep forecasting sort of a leveling off for things like solar and battery, and they keep being wrong.

There's a lot of other things like reusable rockets. Did you think they'd get this good? Did you think we'd have this many satellites in the low-earth orbit?

AI just came out of nowhere. Now everyone has this little personal assistant that's intelligent and can tell them stuff. That didn't exist three years ago.

So is that, perhaps, growing cluster of technologies, that's not just a short-term thing. Do you think all these technologies — and let's say particularly AI, but the healthcare-related stuff as well — that these taken together are a game-changer? Because people always say, “Boy, our lives 30 years ago didn't look much different than our lives today,” and some people say 40 years ago.

But that’s wrong!

Yes, I do think that is wrong, but that people's perception.

When I was a kid, people didn't spend all day looking at a little screen and talking to people around the world through a little screen. Now they do. That's like all they do all day.

But they say that those aren't significant, for some reason, they treat that as a kind of a triviality.

Like me, you're old enough to remember a thing called “getting bored.” Do you remember that? You’d just sit around and you're like, “Man, I’ve got nothing to do. I’m bored.” That emotion just doesn't exist anymore — I mean, very fleetingly for some people, but we've banished boredom from the world.

Remember “getting lost?” If you walk into that forest, you might get lost? That doesn't happen unless you want to get lost, unless you don't take your phone. But the idea that, “Oh my God, I'm lost! I'm lost!” No, just look at Google Maps and navigate your way back.

Being lost and being bored are fundamental human experiences that have been with us for literally millions of years, and now they're just gone in a few years, just gone!

Remember when you didn't know what other places looked like? You would think, “Oh, the Matterhorn, that’s some mountain in Switzerland, I can only imagine what that looks like.” And then maybe you'd look it up in an encyclopedia and see a picture of it or something. Now you just type it into Google Images, or Street View, or look at YouTube, look at a walking tour or something.

Remember not knowing how to fix things? You just had no idea how to fix it. You could try to make it up, but really what you'd do is you'd call someone who was handy with stuff who had this arcane knowledge, and this wizard would fix your cabinet, or your dresser, or whatever, your stereo.

Being lost and being bored are fundamental human experiences that have been with us for literally millions of years, and now they're just gone in a few years, just gone!

So why does that perception persist? I mean, it's not hard to find people — both of us are probably online too much — who just will say that we've had complete and utter stagnation. I don't believe that, yet that still seems to be the perception, and I don't know if things haven't moved fast enough, if there are particular visions of what today should look like that haven’t happened, and people got hung up on the flying-car, space-colony vision, so compared to that, GPS isn’t significant, but I think what you have just described, not everybody gets that.

Because I think they don't often stop to think about it. People don't often stop to think about how much the world has changed since they were young. It's like a gradual change that you don't notice day-to-day, but that adds up over years. It's like boiling the frog: You don't notice things getting better, just like the frog doesn't notice the water getting hotter.

Do you think it's going to get hotter going forward, though? Do you think it's going to boil faster? Do you think that AI is such a powerful technology that it'll be indisputable to everybody that something is happening in the economy, in their everyday lives, and they look a lot different now than they did 10 years ago, and they're going to look a whole lot different 10 years from now?

Utility, remember — back to econ class — utility is concave. A utility of wealth, utility of consumption, is concave, which means that if you get 10,000 more dollars of annual income and you're poor, that makes a hell of a lot of difference. That makes a world of difference to you. But if you're rich, it makes no difference to you. And I think that Americans are getting rich to the point where the new things that happen don't necessarily increase our utility as much, simply because utility is concave. That's how things work.

In the 20th century, people escaped material poverty. They started out the century with horses and buggies, and wood-burning stoves, and freezing in the winter, and having to repair their own clothes, and having food be super expensive, and having to work 60-hour weeks, 80-hour weeks at some sweatshop, or just some horrible thing, and horrible conditions with coal smoke blackening the skies; and then they ended in nice, clean suburbia with computers and HDTVs —I guess maybe we didn't get those till the 2000s — but anyway, we ended the 20th century so much richer.

Basically, material poverty in rich countries was banished except for a very few people with extreme mental health or drug problems. But then for regular people, material want was just banished. That was a huge increment. But if you took the same increment of wealth and did that again in the next century, people wouldn't notice as much. They'd notice a little bit, but they wouldn't notice as much, and I think that it's the concavity of utility that we're really working against here.

In the 20th century, people escaped material poverty. They started out the century. . . having to work 60-hour weeks, 80-hour weeks at some sweatshop. . . and then they ended in nice, clean suburbia with computers and HDTVs . . .

So is economic growth overrated then? That kind of sounds like economic growth is overrated.

Well, no. I don't know that it's overrated. It's good, but I don't know who overrates it. Obviously it's more important for poor countries to grow than for rich countries to grow. Growth is going to make a huge difference to the people of Bangladesh. It's going to be life-changing, just as it was life-changing for us in the 20th century. They're going to have their 20th century now, and that's amazing.

And, to some extent, our growth sustains their growth by buying their products; so that helps, and contributing to innovations that help them, those countries will be able to get energy more easily than we were because they're going to have this super-cheap solar power, and batteries, and all this stuff that we didn't have back in the day. They're going to have protections against diseases, against malaria, and dengue fever, and everything. We didn't have those when we were developing, we had to hack our way through the jungle.

So growth is great. Growth is great, and it's better for the people in the poor countries than for us because of concavity of utility, but it's still good for us. It's better to be advancing incrementally. It's better to be feeling like things are getting better slowly than to be feeling like things aren't getting better at all.

So many things have gotten better, like food. Food has gotten immeasurably better in our society than it was in the ’90s. The food you can eat at a regular restaurant is just so much tastier. I don't know if it's more nutritious, but it's so much tastier, and so much more interesting and varied than it was in the ’90s, and people who are in their 40s or 50s remember that. And if they stop to think about it, they'll be like, “You know what? That is better.” We don't always stop to remember what the past was. We don't remember what food was like in the ’90s — I don't. When I'm going out to a restaurant to eat, I don't think about what a restaurant was like in 1994, when I was a kid. I don't think about that. It just doesn't come to mind. It's been a long time.

In Japan I noticed it a lot, because Japan had, honestly, fairly bland and boring food up until about 2010 or so. And then there was just this revolution where they just got the most amazing food. Now Japan is the most amazing place to go eat in the world. Every restaurant's amazing and people don't understand how recent that is. People don't understand how 20 years ago, 25 years ago, it was like an egg in a bowl of rice and sort of bland little fried things. People don't remember how mediocre it was, because how often did they go to Japan back in 2005?

It's better to be feeling like things are getting better slowly than to be feeling like things aren't getting better at all.

Redrawing the boundaries of energy tech (12:39)

Your answer raised several questions: One, you were talking about solar energy and batteries. Is that enough? Is solar and batteries enough? Obviously I read about nuclear power maybe too much, and you see a lot of countries trying to build new reactors, or restart old reactors, or keep old nuclear reactors, but over the long run, do we need any of that other stuff or can it really just be solar and batteries almost entirely?

Jesse Jenkins has done a lot of modeling of this and what would be the best solutions. And of course those models change as costs change. As battery costs go down and battery capabilities improve, those models change, and we can do more with solar and batteries without having to get these other things. But the current models that the best modelers are making right now of energy systems, it says that we're probably looking at over half solar and batteries, maybe two thirds, or something like that. And then we'll have a bunch of other solutions: nuclear, wind, geothermal, and then a little bit of gas, we'll probably never completely get rid of it.

But then those things will all be kind of marginal solutions because they all have a lot of downsides. Nuclear is very expensive to build and there's not much of a learning curve because it gets built in-place instead of in a factory (unless it's on a submarine nuclear plant, but that's a different thing). And then wind takes too much land, really, and also the learning curve is slower. Geothermal is only certain areas. It's great, but it's only certain areas. And then gas, fossil fuel, whatever.

But the point is that those will all be probably part of our mix unless batteries continue to get better past where we even have expected them to. But it's possible they will, because new battery chemistries are always being experimented with, and the question is just: Can we get the production cost cheap enough? We have sodium ion batteries, iron flow batteries, all these other things, and the question is, can we get the cost cheap enough?

Fortunately, China has decided that it is going to pour untold amounts of capital and resources and whatever into being the Saudi Arabia of batteries, and they're doing a lot of our work for us on this. They're really pushing forward the envelope. They're trying to scale every single one of these battery chemistries up, and whether or not they succeed, I don't know. They might be wasting capital on a lot of these, or maybe not, but they're trying to do it at a very large scale, and so we could get batteries that are even better than we expect. And in that case, I would say the share of solar and batteries would be even higher than Jesse Jenkins and the other best modelers now predict.

But you don't know the future of technology. You don't know whether Moore's Law will stop tomorrow. You don't know these things. You can trace historical curves and forecast them out, and maybe come up with some hand-wavy principles about why this would continue, but ultimately, you don't really know. There's no laws of the universe for technological progress. I wish there were, that'd be cool. But think solar and batteries are on their way to being a majority of our total energy, not just electricity, but total energy.

Racing China in research (15:59)

Does it concern you, in that scenario, that it's China doing that research? I understand the point about, “Hey, if they want to plow lots of money and lose lots of money,” but, given geopolitical relations, and perhaps more tariffs, or war in the South China Sea, does that concern you that that innovation is happening there?

It absolutely does concern me. We don't want to get cut off from our main sources of energy supply. That's why I favor policies like the Inflation Reduction Act. Basically, industrial policy is to say, “Okay, we need some battery manufacturing here, we need some solar panel manufacturing here in the country as a security measure.” Politicians always sell it in terms of, “We created this many jobs.” I don't care. We can create jobs anyway. Anything we do will create jobs. I don't care about creating specific kinds of jobs. It is just a political marketing tactic: “Green jobs, yes!” Okay, cool, cool. Maybe you can market it that way, good for you.

But what I do care about is what you talked about, which is the strategic aspect of it. I want to have some of that manufacturing in the country, even if it's a little inefficient. I don't want to sacrifice everything at the altar of a few points of GDP, or a few tenths of a percent of points of GDP at most, honestly. Or sacrifice everything in the altar of perfect efficiency. Obviously the strategic considerations are important, but, that said, what China's doing with all this investment is it's improving the state of technology, and then we can just copy that. That's what they did to us for decades and decades. We invented the stuff, and then they would just copy it. We can do that on batteries: They invent the stuff, we will copy it, and that's cool. It means they're doing some of our work, just the way we did a lot of their work to develop all this technology that they somehow begged, borrowed, or stole.

. . . what China's doing with all this investment is it's improving the state of technology, and then we can just copy that. That's what they did to us for decades and decades. We invented the stuff, and then they would just copy it. We can do that on batteries. . .

The original question I asked about: Why should we think the future will be different than the recent past? Why should we think that, in the future, America will spend more on research? Why do we think that perhaps we'll look at some of the regulations that make it hard to do things? Why would any of that change?

And to me, the most compelling reason is, it's quite simple just to say, “Well, what about China? Do you want to lose this race to China? Do you want China to have this technology? Do you want them to be the leaders in AI?” And that sort of geopolitical consideration, to me, ends up being a simple but yet very persuasive argument if you're trying to argue for things which very loosely might be called “pro-progress” or “pro-abundance” or what have you.

I don't want to whip up any international conflict in order to stimulate people to embrace progress for national security concerns. That wouldn't be worth it, that’s like wagging the dog. But, given that international conflict has found us — we didn't want it, but given the fact that it found us — we should do what we did during the Cold War, during World War II, even during the Civil War, and use that problem to push progress forward.

If you look at when the United States has really spent a lot of money on research, has built a lot of infrastructure, has done all the things we now retrospectively associate with progress, it was for international competition. We built the interstates as part of the Cold War. We funded the modern university system as part of the Cold War. And a lot of these things, the NIH [National Institutes of Health], and the NSF [National Science Foundation], and all these things, of course those came from World War II programs, sort of crash-research programs during and just before World War II. And then, in the Civil War, of course, we built the railroads.

So, like it or not, that's how these things have gotten done. So now that we see that China and Russia have just decided, “Okay, we don't like American power, we want to diminish these guys in whatever way we can,” that's a threat to us, and we have to respond to that threat, or else just exceed to the loss of wealth and freedom that would come with China getting to do what it wants to us. I don't think we should exceed to that.

I don't want to whip up any international conflict in order to stimulate people to embrace progress. . . But, given that international conflict has found us. . . we should do what we did during the Cold War, during World War II, even during the Civil War, and use that problem to push progress forward.

Recalling Japanese economic history (20:32)

You write a lot about Japan. What is the thing you find that most people misunderstand about the last 30 years of Japanese economic history? I think the popular version is: Boom, in the ’80s, they looked like they were ahead in all these technologies, they had this huge property bubble, the economy slowed down, and they've been in a funk ever since — the lost decades. I think that might be the popular economic history. How accurate is that?

I would say that there was one lost decade, the ’90s, during which they had a very protracted slowdown, they ameliorated many of the effects of it, but they were very slow to get rid of the root cause of it, which was bad bank debts and a broken banking system. Eventually, they mostly cleaned it up in the 2000s, and then growth resumed. By the time per capita growth resumed, by the time productivity growth and all that resumed, Japan was aging very, very rapidly, more rapidly than any country has ever aged in the world, and that masked much of the increase in GDP per worker. So Japan was increasing its GDP per worker in the 2000s, but it was aging so fast that you couldn't really see it. It looked like another lost decade, but what was really happening is aging.

And now, with fertility falling all around the world right now in the wake of the pandemic, probably from some sort of effect of social media, smartphones, new technology, whatever, I don't know why, but fertility's falling everywhere — again, it looked like it had bottomed out, and then now it's falling again. We're all headed for what happened to Japan, and I think what people need to understand is that that's our future. What happened to Japan in the 2000s where they were able to increase productivity, but living standards stagnated because there were more and more old people to take care of. That is something that we need to expect to happen to us, because it is. And, of course, immigration can allay that somewhat, and it will, and it should. And so we're not because of immigration

Will it in this country? In this country, the United States, it seems like that should be something, a major advantage going forward, but it seems like it's an advantage we seem eager to throw away.

Well, I don't know about eager to throw away, but I think it is in danger. Obviously, dumb policies can wreck a country at any time. There's no country whose economy and whose progress cannot be wrecked by dumb policies. There's no country that's dumb-proof, it doesn't exist, and it can't exist. And so if we turn off immigration, we're in trouble. Maybe that's trouble that people are willing to accept if people buy the Trumpist idea that immigrants are polluting our culture, and bringing all kinds of social ills, and eating the pets, and whatever the hell, if people buy that and they elect Trump and Trump cracks down hard on immigration, it will be a massive own-goal from America. It will be a self-inflicted wound, and I really hope that doesn't happen, but it could happen. It could happen to the best of us.

There's no country whose economy and whose progress cannot be wrecked by dumb policies. There's no country that's dumb-proof, it doesn't exist, and it can't exist.

Regulating AI well (23:49)

Do you think what we're seeing now with AI, do you think it is an important enough technology that it is almost impossible, realistically, to screw it up through a bad regulation, through a regulatory bill in California, or something on the national level? When you look at what's going on, that if it's really as important as what perhaps the most bullish technologists think it is, it's going to happen, it's going to change businesses, it's going to change our lives, and unless you somehow try to prohibit the entire use of the technology, there's going to be an Age of AI?

Do people like me worry too much about regulation?

I can't say, actually. This is not something I'm really an expert on, the potential impact of regulation on AI. I would never underestimate the Europeans' ability to block new technologies from being used, they seem to be very, very good at it, but I don't think we'll completely block it, it could hamper it. I would say that this is just one that I don't know.

But I will say, I do think what's going to happen is that AI capabilities will outrun use cases for AI, and there will be a bust relatively soon, where people find out that they built so many data centers that, temporarily, no one needs them because people haven't figured out what to do with AI that's worth paying a lot of money for. And I have thoughts on why people haven't thought of those things yet, but I'll get to that in a second. But I think that eventually you'll have one of those Gartner Hype Cycles where eventually we figure out what to do with it, and then those data centers that we built at that time become useful. Like, “Oh, we have all these GPUs [graphics processing units] sitting around from that big bust a few years ago,” and then it starts accelerating again.

So I predict that that will happen, and I think that during the bust, people will say, just like they did after the Dot-com bust, people will say, “Oh, AI was a fake. It was all a mirage. It was all useless. Look at this wasted investment. The tech bros have lied to us. Where's your future now?” And it's just because excitement about capabilities outruns end-use cases, not all the time, obviously not every technology obeys this cycle, for sure . . . but then many do, you can see this happen a lot. You can see this happen with the internet. You can see this happen with railroads, and electricity. A lot of these things, you've seen this pattern. I think this will happen with AI. I think that there's going to be a bust and everyone's going to say, “AI sucks!” and then five, six years later, they'll say, “Oh, actually AI is pretty good,” when someone builds the Google of AI.

Rethinking growth strategy in the EU (26:46)

To me, this always gets a lot of good attention on social media, if you compare the US and Europe and you say, the US, it's richer, or we have all the technology companies, or we're leading in all the technology areas, and we can kind of gloat over Europe. But then I think, well, that's kind of bad. We should want Europe to be better, especially if you think we are engaged in this geopolitical competition with these authoritarian countries. We should want another big region of liberal democracy and market capitalism to be successful.

Can Europe turn it around? Mario Draghi just put out this big competitiveness report, things Europe can do, they need to be more like America in this way or that way. Can Europe become like a high-productivity region?

In general, European elites’ answer to all their problems is “more Europe,” more centralization, make Europe more like a country. . . But I think that Europe's strength is really in fragmentation . . .

I think it can. I wrote a post about this today, actually, about Mario Draghi's report. My bet for what Europe would have to do is actually very different than what the European elites think they have to do. In general, European elites’ answer to all their problems is “more Europe,” more centralization, make Europe more like a country. You know, Europe has a history of international competition. France, and Germany, and the UK, and all these powers would fight each other. That's their history. And for hundreds of years, it's very difficult to change that mindset, and Mario Draghi's report is written entirely in terms of competitiveness. And so I think the mindset now is “Okay, now there's these really big countries that we're competing with: America, China, whatever. We need to get bigger so we're a big country too.” And so the idea is to centralize so that Europe can be one big country competing with the other big countries.

But I think that Europe's strength is really in fragmentation, the way that some European countries experiment with different institutions, different policies. You've seen, for example, the Scandinavian countries, by and large, have very pro-business policies combined with very strong welfare states. That's a combination you don't see that in Italy, France, and Germany. In Italy, France, and Germany, you see policies that specifically restrict a lot of what business can do, who you can hire and fire, blah, blah, blah. Sweden, and Denmark, and Finland, and Norway make it very easy for businesses to do anything they want to do, and then they just redistribute. It's what we in America might even call “neoliberalism.”

Then they have very high taxes and they provide healthcare and blah, blah, and then they basically encourage businesses to do business-y things. And Sweden is more entrepreneurial than America. Sweden has more billionaires per capita, more unicorns per capita, more high-growth startups per capita than America does. And so many people fall into the lazy trap of thinking of this in terms of cultural essentialism: “The Swedes, they're just an entrepreneurial bunch of Vikings,” or something. But then I think you should look at those pro-business policies.

Europeans should use Sweden as a laboratory, use Denmark, use Norway. Look at these countries that are about as rich as the United States and have higher quality of life by some metrics. Look at these places and don't just assume that the Swedes have some magic sauce that nobody else has, that Italy and Greece and Spain have nothing to learn from Sweden and from Denmark. So I think Europe should use its fragmentation.

Also, individual countries in Europe can compete with their own local industrial policies. Draghi talks about the need to have a Europe-wide industrial policy to combat the industrial policies of China and America, but, often, when you see the most effective industrial policy regimes, they're often fragmented.

So for example, China until around 2006, didn't really have a national industrial policy at all. At the national level, all they did was basically Milton Friedman stuff, they just privatized and deregulated. That's what they did. And then all the industrial policy was at the provincial and city levels. They went all out to build infrastructure, to attract FDI [foreign direct investment], to train workers, all the kinds of things like that. They did all these industrial policies at the local level that were very effective, and they all competed with each other, because whichever provincial officials got the highest growth rate, you'd get promoted, and so they were competing with each other.

Now, obviously, you don't want to go for growth at the expense of anything else. Obviously you'd want to have things like the environment, and equality, and all those things, especially in Europe, it's a rich country, they don't just want to go for growth, growth, growth only. But if you did something like that where you gave the member states of the EU more latitude to do their local policies and to set their local regulations of things like the internet and AI, and then you use them as laboratories and copy and try to disseminate best practice, so that if Sweden figures something out, Greece can do it too, I think that would play to Europe's strength, because Draghi can write a million reports, but Europe is never going to become the “United States of Europe.” Its history and ethno-nationalism is too fragmented. You'll just break it apart if you try.

The European elites will just keep grousing, “We need more Europe! More Europe!” but they won't get it. They'll get marginally more, a little bit more. Instead, they should consider playing to Europe's natural strengths and using the interstate competitive effects, and also laboratory effects like policy experimentation, to create a new development strategy, something a little bit different than what they're thinking now. So that's my instinct of what they should do.
