- 财富是资产的账面价格,消费和偿债需要的是现金。
- 资产上涨扩大抵押能力与借贷,反向运行时则形成被迫抛售。
- 利润跟不上价格不否定技术,只是否定当前资本结构和估值。
主持人 Are you seeing signs that we're in an AI bubble, and therefore a economic collapse?
嘉宾 The classic signs. And that has implications for the economy, and it's bad for the society, and everybody loses money. But we also have some other things that are going on that happen around the same time. And I can go through these if you want.
主持人 Please.
嘉宾 So what I'm saying is clear, because I'm a global macro investor.
主持人 And you were one of the few managers to foresee the great financial crisis.
嘉宾 Yes. And so right now we're very excited about AI, and we should be very excited, cuz it's going to be revolutionary changes. But it's creeping into almost everything. The way I look at it is I look at the human body, and I see like it's replacing the body and so on. And then it replaces some aspects of the mind, levels of thinking and reasoning. But at the same time, we have another problem that's existing, geopolitics. I mean, that China is a larger trading partner with mos
t countries than the United States is.
主持人 And that's a changing of the world order.
嘉宾 That is one of the ingredients, right? And then also, you've got large wealth gaps. The government don't have enough money. And so when you have the downturn, then you have people at each other's throats.
主持人 So a lot of people that thinking about how to sort of secure their future, how do they all prepare?
嘉宾 Let me say that history has shown that it's not the most intelligent people that are the most successful. But the key to things to keep in mind is

嘉宾 Right. For people that might not know who you are, you founded Bridgewater Associates in a two-bedroom apartment in 1975, and you grew it to the world's largest hedge fund. What was the the total amount of cumulative net gains that you delivered for those investors over that period?
主持人 I think it was something like 53 billion. We produced about a 12% return with no never any significant losses, and it was uncorrelated with other investments.
嘉宾 And you were the one of the few managers to foresee the great financial crisis, which allowed Bridgewater to post positive returns of 9.5% in 2008, while the S&P 500 plunged by almost 40%.
主持人 Yeah.
嘉宾 Let me start with the thing that I'm most curious about, because I sat here with an investor called Jeremy Grantham, who you might know.
主持人 Mhm.
嘉宾 He told me that we're staring in the face of an AI bubble, and therefore a economic collapse potentially.
主持人 If you look at the data, it would be compatible with history for the peak to be very soon. Everything is in line. This is I think the biggest investment bubble in American history.
嘉宾 What's your perspective on that?
主持人 He's right. I don't want to jump to conclusions as much as I want to explain reasonings that lead up to conclusions. I'm at a stage in my life that I want to help people understand cause-effect relationships. What they call a bubble is when the price goes up a lot and companies do very well and then it collapses. And that has implications for the economy, it has implications for the markets. Like 1929 bubble. Okay? Or the 2000 bubble. Okay? Which was the dot-com bubble.
嘉宾 Does it impact real people as well? Cuz you said the economy and
主持人 It did. 1929 bubble bursting impact real people?
Yes, the Great Depression followed. Because what happens is there's a new technology that comes along that's revolutionary. The dot-com bubble, which was 2000, all the stuff that we have that's wonderful new technology. People get into that technology. They say that's miraculous. I can bet on that. I'm sure it's going to be successful. And then they bet on it. And sometimes they borrow money to bet on it. And they lose sight that the price of it matters. So, it goes up and it it's everybody's thing, you know?
Like right now, we're very excited about AI and we should be very excited cuz it's going to be revolutionary changes. And it then at the same time, so I want to buy some of that. And everybody wants to invest in some of that. And what they do is they don't pay attention to the price and there's a certain mechanics. People will borrow money. Wealth is not the same as money. So, you see a lot of people getting wealthy, but you can't spend the wealth. You have to sell the wealth to get money.
Cuz you can only spend money, right?So, what happens is when they need money for one reason or another, taxes change or interest rates go up and so they have to pay their debt service and so on. There is a pricking of the bubble, so that what happens is it falls. Okay?And when that happens, people lose money. And as they start to lose money, the process works in reverse because when they made a lot of money, they have a lot of collateral, right?
They can go borrow money because they're worth a lot. And that compounds on its way up. And then when it comes down the other way, it works the other way. Okay, now you got to pay your debt. And so when then you have to start to sell assets. And then there's less demand for things, right?
So there's less demand because if you're losing money cuz you put some money in the stock market and that company and so on, you're going to spend less. And as you spend less, then somebody else's income goes down, right?
So you don't go to the restaurants. The economic downturns that typically follow a bubble like the Great Depression. The late '20s was fantastic. If you talk about changes and and experiencing This was the first time there was electricity in houses. So that was the first time you would have refrigeration and you would have lighting in houses. This was the first time that you had um cars popular. That you could First time airplanes. First time you had radio. And so everybody knew that they were going to be great in the future and they were great in the future. But at the same time, what happens is as they buy them and they stocks go up and they borrow money to buy them and so on. Um and the profits don't live up to the price, then that causes this other dynamic and it produced the Great Depression.
嘉宾 So let's say that I buy this and this is a unit of artificial intelligence. So let's say I buy one share in one of the big AI companies right now because investors are so excited about AI, they value this at $100. This unit that I have here. They say it's worth $100. So my net worth is now $100. I go to the bank because I have this net worth, this paper worth $100 and I ask the bank for a 50% loan on this right thing that I have. They give me $50. Now I have $50. And then som
ething happens in the economy which means that the investors who have invested in this and investors generally now need money to pay off their other debts that they have. So this could be a war, it could be some kind of event that takes place and suddenly everybody rushes to sell their assets like this one. And so when I go to sell this, the price of it has now plummeted to say maybe $25, but I took a loan at the bank for $50, so I owe the bank $50, but now this thing that I
have that was worth $100 a couple of months ago is now worth $25 and I'm $25 in the hole. So I have to quickly sell.
And then with everybody selling, all the price of assets drop, people stop spending money at the restaurants like you say, there's less money around and then the bubble has burst and we're in this sort of declining
主持人 You got it.
嘉宾 Okay, good. All right, fine.
主持人 And it happens because it must happen. I mean meaning in these uh tremendous uh changes, uh there's very little that's known. So anybody who's in the business of making AI uh can't be precise. They don't know exactly how much money is going to come in, right?So there's either one of two things. You either don't invest enough and then the competition runs away or you invest a huge amount and you can't be precise, okay?
And so when that dynamic happens, it's a problem. So yes, you said it very well. So I'm going to repeat one other thing to emphasize. What's quite common now is um you can issue stock for uh let's say you raise $50 million. And you value the company at a billion dollars. Only $50 million was actually spent on that company. But now if you raise that, you're a billionaire.
嘉宾 Mhm.
主持人 Okay? Because the accounting value of that What do you own? You own stock that is valued at a billion dollars. Nobody paid a billion dollars or whatever it is, right? And now you own that stock. But that stock, um, you can't spend. Cuz you can't spend wealth.
嘉宾 Mhm.
主持人 In order to spend it, you have to sell some of that stock to get money.
嘉宾 Yeah.
主持人 Right? And quite often there's an interest rate rise because the you know, let's say as there's a fever and there's an inflation and the central bank wants to try to put the brakes on that a bit. Okay, what does that mean? It means people who have debt, in a sense, have to come up with more money.
嘉宾 Mhm.
主持人 Cuz when you own the debt all the debt, you have to come up with money to pay the debt.
嘉宾 So the downturn works.
主持人 Between us, we've said it uh clearly, I think we can understand the dynamic. So they they have to exist. Now we have another problem that's existing, okay?So we're talking about the bubble, okay?But we also have some other things that are going on that happen around the same time. A big gap between the rich and the poor and which also means the left and the right, the politics of it, right?
Just as we have now. When you have the downturn, um, then you have people at each other's throats. So if we take politics, what you see is this that they don't have enough money. The the governments don't have enough money. We have big budget deficits, okay?Where do you get the money from in order to pay those bills?
The UK has had, I think, six out of last seven years there's been a new prime minister. And because there's not enough money for the government, and so what you start to see is people come in with their claims, but there's this how do we get the money?
And then people run who have money, they say, "I don't want to be in this tax zone that's going to be." And then they leave. And so there's a domestic political problem that is not people compromising the same way they used to compromise, right?
So now you have the politics which compounds this. And And then you have a world, this is what I call the big cycle. You have a world in which also the geopolitics changes. By geopolitics, I mean country to country. Okay, there's a system under normal circumstances. When there's a more dominant power, they impose their order and that becomes more peaceful.
But when you have on uh arguments of how things should go, those arguments start to turn into conflicts, right?
And so, those things tend to happen together. That's why I refer to that as the big cycle, that dynamic. Now, that is the confluence of the money, the internal conflict politically, and the external conflict, which is what we're going through. And And the problem is, I think, that people don't know the cycle. So, every day we go to our sources of information and you see this latest news, but they don't connect the dots in in understanding that cycle.
