\"泡沫的心理学:警惕 AI 与加密货币的狂热\" TED 2025-12-19

泡沫心理学:集体非理性与风险警示

我们常常被一些“群体共识”所裹挟,即使它们可能带来危险的后果。正如“詹特法则”(Law of Jante)所警示的,不要认为自己比他人更特别、更优越。这种思维定势在金融市场中尤为明显,常常导致我们低估风险,忽视警告。当前,围绕着比特币、加密货币乃至AI的狂热,正是这种集体非理性的一个缩影。就连世界上最成功的投资者之一沃伦·巴菲特(Warren Buffett)和已故的查理·芒格(Charlie Munger)都曾用极为尖锐的言辞形容比特币,例如称其为“性病”(venereal disease)或“老鼠药的平方”(rat poison squared)。他们对加密货币的警惕,恰恰源于对金融泡沫的深刻理解。

尽管比特币一路走来创造了惊人的回报,吸引了无数追随者,甚至催生了“Lambo Guy”这样的现象,但理解那些成功投资者的警告至关重要。他们凭借数十年的投资经验,实现了数百万百分比的回报,他们的观点绝非空穴来风。

So, don't think you're special. Don't think that you know more than we do. These are some of the statements from the Law of Jante. And I think that is dangerous. I think that is actually driving a common thinking that can bring, you know, hazard outcomes. And today I want to talk about something that may be a little more dry than what we have just heard, which is Bitcoin, crypto, bubbles, financial bubbles. "Bitcoin is a venereal disease." "Bitcoin is rat poison squared." These are not my words. These are the words of Charlie Munger and Warren Buffett, two of the most prominent investors this world has ever seen. Most successful investors. Five million percent in returns over their investment careers, speaks for itself. So when they talk and speak, and unfortunately, Mr. Munger is dead, but when they did talk or when they they'd speak, we have to listen. And I definitely listen. Bitcoin has, of course, had a fantastic journey and we all need to praise, of course, the amazing returns that that has given over the years. But when we hear about it, of course, we have to wonder why are the two most successful investors in the world talking about it like rat poison?

FOMO与群体动力学:驱动泡沫的心理根源

驱动人们在泡沫中狂热追逐的,是一种深植于人类本能的心理机制——错失恐惧症(FOMO,Fear of Missing Out)。这种恐惧源于我们作为狩猎采集者的祖先,群体生存的保障(食物、安全、繁衍)使得与群体保持一致成为生存的关键。脱离群体意味着危险。这种古老的本能,在现代社会被放大,尤其是在信息爆炸和快速变化的金融市场中。当我们看到他人因某种资产获得巨额收益时,FOMO会让我们产生“不参与就落后”的焦虑,从而冲动决策。

历史上有许多名人也未能幸免于FOMO的陷阱。例如,伟大的科学家艾萨克·牛顿(Sir Isaac Newton)在1700年代就曾投资于“南海泡沫”(South Sea bubble)。他早期获利后退出,但看到朋友们因此变得更加富有,他便因FOMO再次投入巨资,最终在泡沫破裂时损失惨重。他痛苦地总结道:“我可以计算天体的运行,却无法计算人性的疯狂。”

群体动力学(crowd dynamics)是泡沫形成的另一重要因素。1968年的一项“烟雾房间实验”(smoked room experiment)揭示了这一点:在一个房间里,八名假扮者对门缝中冒出的烟雾视而不见,当真正的申请者独自一人时,他更有可能报告异常情况。这表明,群体行为和从众心理会改变个体的判断和行动,即使面对显而易见的问题。

I can tell this personal story. In 2016, I was close to investing in Bitcoin. Actually buying around maybe 150,000 dollar's worth of Bitcoin, which today would have had a value of around 20 to 25 million dollars. I didn't do it, I didn't get to it because of the difficulties in actually getting the money transferred from a bank to a wallet back then. But one of my friends actually did enter, did take the crypto plunge, and he entered Ethereum, which is another crypto, at a time when it was at 50 cents. And he held on to it until the moment it actually reached around 1,400 dollars. So 2,800 times. And he's not the only one that has done well when it comes to crypto. We've all heard of these Lambo guys, or people that have jumped into something that seems ridiculous, only to see it go up 100 times. I don't know about you, but I definitely can feel the FOMO. FOMO, what is that? FOMO, fear of missing out. Well fear of missing out is something that is very deep in the human mind. It goes back to the times as we lived as hunters and gatherers in groups. Being part of the group ensured food, security, mating, and being outside was dangerous. And that's something we have taken on to us today, also. If we're not part of the group, if we don't think alike, like, the Jante law is also kind of commending. Well then it's dangerous. So fear of missing out, FOMO, is something that is deeply in us, and is something that can make us maybe come up to conclusions or do things we don't necessarily would do if we were just ourselves. And this is not something just maybe I, as a stupid person, or people that don't understand things, do. Sir Isaac Newton is probably one of the most intelligent people that has ever lived. And in the 1700s, he actually were a victim of FOMO. So that was the time of the South Sea bubble. Newton invested in, saw his stock rise, earned a good money, got out, but saw his friends actually staying in and becoming even more rich. He FOMO-ed in, invested more, actually a lot. And the bubble burst. He famously said afterwards, "I can calculate the movement of heavenly bodies, but not of the madness of men." So FOMO can make us do things we don’t want, that can be against what we actually -- what is good for us. And that is actually also very visible, that crowd dynamics that is a part of, when we talk about what is called the smoked room experiment. This is an experiment from 1968, where a group of applicants to a job is invited in to a room. Eight of the nine applicants are actors. They are told to stay seated, just work on their assignment no matter what happens. One person is a real applicant. All of a sudden, while they do their application, smoke comes through the door. When there are other people, the other eight actors are in the room, 90 percent of the time people stay seated and do not report on the smoke, on the potential hazardous event that is unfolding. But when that person, the applicant is alone, 75 percent of them got up and actually reported on the smoke. So crowd dynamics is something that changes the way we think. And that is what actually also is part of why we see financial bubbles developing.

历史上的泡沫:技术浪潮与非理性繁荣

金融泡沫并非新近事物,其模式在历史长河中反复上演。从17世纪的“郁金香狂热”(Tulip Mania)到20世纪末的互联网泡沫,每一次泡沫的形成都伴随着新的技术或概念的出现,点燃了人们的想象,并最终因非理性繁荣而破灭。

  • 郁金香狂热(1630年代):一种来自奥斯曼帝国的新奇植物,在荷兰引发了史无前例的投机狂潮。人们购买郁金香并非因为其观赏价值或实用性,而是寄希望于第二天能以更高的价格转售。泡沫破裂时,一颗郁金香球茎的价格甚至相当于一栋房子的价值。
  • 19世纪40年代英国的铁路热潮:蒸汽机和火车头的出现曾被视为改变世界的革命性技术。无数公司应运而生,市场充斥着“绝不会赔钱”的乐观情绪。然而,这种过度投资最终导致了泡沫的破裂,许多人损失惨重,尽管火车技术本身确实改变了世界。
  • 20世纪20年代的“咆哮的二十年代”:一战后的电气化、汽车和广播技术的普及,为人们带来了前所未有的新奇体验。然而,这种对新时代的狂热也催生了巨大的金融泡沫,最终在1929年股市崩盘后引发了大萧条。
  • 互联网泡沫(Dot-com bubble):上世纪末,互联网的兴起被视为“新经济”的开端。市场不再关注盈利能力,而是过度投资于营销和概念,华尔街和媒体(如WebvanPets.com)的追捧更是将泡沫推向顶峰。尽管互联网无疑改变了世界,但市场对公司价值的判断却陷入了非理性狂热。

这些历史案例清晰地表明,即使是革命性的技术,也不能保证市场不会出现非理性繁荣和随后的崩溃。

Original English

If we look at financial bubbles, then we saw one of the largest financial bubbles back in the 1630s, which was called the Tulip Mania. It was at a time where the tulip had been introduced from the Ottoman Empire, and for some reason, it became the center of attention. People start buying it, and market rose up, and people kept buying this tulip or the tulips, not because of its utility, but because they thought they could sell it off the next day to earn money. The bubble burst at the peak of that hype, of that mania, and that's just to explain how mad it can become. One tulip bulb had the price of a house at that time. Then we can fast forward to the 1840s Britain. And this was at a time where a fantastic technology came out. Steam engine, the locomotive, promised to change the world, and it certainly did. But the thing was, everybody thought that this is now changing ways, also, we will earn money, and everybody FOMO-ed in. Thousands of companies rose up, were established. People thought this is a cannot-lose opportunity. And again, we saw how a bubble burst, and a lot of people actually lost money. And this was still because, even though there was a really fantastic technology that changed the world. We can then fast-forward to the roaring '20s and try and imagine, that was the time where we have just seen the end of the first World War. We saw the electrification, we saw the technology of a car. We saw radio coming out. Try and imagine sitting there in your silent home, all of a sudden you can turn on the radio and you can hear people speaking to you. That was quite something. Turning on the light, getting yourself into the car and driving instead of having horses. We think we have seen leap in technology. Well, I can tell you, that was special. And what happened then? Again, we saw people FOMO into it. Because this is, of course, a new world, this new time, forget about the old world. And a massive bubble unfolded. Again it burst. And as we probably know, as we heard from school, we saw the stock market crashing, we saw the large depression in the US and elsewhere, because of this FOMO. And then we can fast forward to something we may be able to remember, at least some of us with a little more gray hair. So that was dot-com bubble. And this was at a time where another new technology came out, just like the steam engine and the radio. And now we had the internet, and everybody again FOMO-ed in. What's not to like? Fantastic opportunity. The world is new, new economy, they called it. And it's no longer about how much you earn. It's about how much you spend on marketing. And there was a fantastic support to this. Wall Street were all behind it, media were all behind it. There were media darlings like Webvan and Pets.com. So the media were all over this. Everybody was praising this new, fantastic and brave world. Did the internet change the world? Absolutely. But is that the same as a promise that you cannot see that the market can crash, or that people get exuberant? No.

当前泡沫:AI与加密货币的“皇帝新衣”

现在,我们将目光转向当前最受瞩目的两个领域:AI与加密货币,尤其是比特币。演讲者认为,这构成了我们目前所见的最大金融泡沫。他援引沃伦·巴菲特提出的“市值对GDP比率”作为衡量泡沫大小的指标。历史上,1929年为89%,2000年为136%,2007年为107%。而当前这一比率已飙升至惊人的226%。

与此同时,一些科技公司如英伟达(Nvidia)和Palantir,在15年内实现了高达94,000%的回报,这显然是“非常泡沫化”(frothy)的。比特币自2012年以来更是上涨了120万%。这种惊人的涨幅,以及比特币纳斯达克指数之间的高度相关性,预示着风险。纳斯达克在2001年就曾经历过85%的崩盘,而如今的泡沫规模远大于当时。演讲者大胆预测,当泡沫破裂时,比特币的跌幅可能高达95%。

这种现象,如同汉斯·克里斯蒂安·安徒生(Hans Christian Andersen)的童话《皇帝的新衣》:故事中的皇帝因虚荣而相信了两名骗子的话,让他们为自己制作“看不见的”新衣。即使在臣民和顾问都无法看见的情况下,人们因害怕被视为愚蠢或不称职而不敢说出真相。最终,只有一个天真的孩子喊出了那句显而易见的事实:“他根本没穿衣服!”。演讲者以此类比,指出当前市场中,许多人可能正因害怕被视为不懂AI加密货币潮流而被抛弃,而不敢质疑那些显而易见的泡沫迹象。

Original English

So now I want to talk about Bitcoin. Because I think Bitcoin is the very definition of this financial bubble we have at this point. AI and crypto bubble. But before I do that, now we talked about Jante, but I'm from Denmark. In Denmark, we have a famous fairytale teller, Hans Christian Andersen, who had the story or told the story of “The Emperor’s New Clothes.” And this is the story, for the ones who don't know it already, of course, this is about the emperor who lived in his empire. And one day, two fraudsters came to town. And those were tailors. They would be able to make the most fantastic clothes that he had ever seen, so he could stand out really nice. He was very vain. And he, of course, got intrigued. There was, however, this one caveat to it. That if people were especially stupid or were not good at what they do, they would not be able to see the clothes. And the emperor thought that was interesting, and he sent them off and they started to work, the two fraudsters, on their looms, weaving and making the clothes. The emperor got impatient and sent off his best advisor and said, "Can you go to check on how it's going?" The advisor came to the fraudsters and couldn't see the clothes. And he thought, "What is that going to tell of me if I can't see the clothes? I'm not going to do that." So he went back to the emperor, said, “Oh, that’s amazing, sir. You love it, it's fantastic." And then the emperor thought, “OK, I’ve got to go see myself.” And he went. And again, he couldn't see the clothes. And he thought, "What is that going to tell my people about who I am?" Oh, sorry about that. There we go. "And how I run the country." So what he did was, again, like his advisor, to simply just keep silent. And the day came where he was supposed to walk down the street, as we do when we get new clothes, we like to show it off. And the fraudsters helped him put on the clothes and he walked down the street. And everybody, all in the crowd, were saying how fantastic this was, especially the elite. "Wow. Amazing garment." Until a little boy cried out, "But why isn't he wearing any clothes?" Now why am I saying that? What is the moral? Of course, that sometimes it takes an innocent mind, naive mind maybe, to point out what is obvious. And now I want to turn to Bitcoin, because, as I said, we currently have the largest financial bubble that we have ever seen. I have just told you about four massive bubbles, and I'm claiming we have one that is even bigger. Warren Buffett and Charlie Munger had a way of looking at that. That is the market capitalization to GDP ratio. Let's just put it there. The higher it is, the bigger the bubble. In 1929, 89 was the number there. 2000, massive bubble. We laughed at it afterwards. It was 136 percent. 2007, it was at 107 percent. These are the two lumps you see there. This is where we are today, 226 percent. And we can just look at some of the businesses that are doing well today. As I said, a crypto and AI bubble. Nvidia, Palantir. It looks like the Tulip bubble to me. I mean, you don't need to know much about finance to see that 94,000 percent in a matter of 15 years. That's pretty frothy. Nasdaq, Bitcoin. Bitcoin is up 1.2 million percent since 2012. So now people say, yeah, but, you know, it can keep going up. Well if you have a bubble and it bursts and you can see that Nasdaq and Bitcoin are following each other very, very closely, and you also know that Nasdaq actually tumbled, crashed 85 percent after 2001, in that massive bubble that is way smaller than what we have today. Now guess what is going to happen to Bitcoin. When Bitcoin crashes much, much more, every time we see a decline in Nasdaq. I say Bitcoin is going to crash by 95 percent. That's not what we hear when we hear the media, the academia, the crowd and the emperor’s new clothes talking about this.

经济放缓与泡沫的终结

与此同时,经济放缓的迹象日益明显。失业率的上升常常预示着经济衰退的到来,而衰退正是泡沫破裂的催化剂。当前,我们正处于一个比2001年纳斯达克崩盘时规模更大的泡沫之中。当经济滑入衰退,市场信心崩溃,AI和加密货币等资产的估值将面临严峻考验。

演讲者最终总结道,比特币和加密货币确实代表了一种技术创新,但这并不等同于投资回报的保证。它们很可能是一个即将破裂的巨大泡沫,其影响将是深远的。正如巴菲特芒格所言,它们可能就像一种“venereal disease”,对那些沉迷其中的投资者造成严重的、难以摆脱的伤害。识别并警惕这种由FOMO和群体心理驱动的非理性繁荣,是保护个人财富的关键。

Original English

So ... And then we also have a situation where we have a slowdown in the economy. It's very visible. We don't need to know much about economy to see these rounding bottoms. This is unemployment level in the US. Every time they move up, you get a recession. A recession is where bubbles burst. And when a bubble bursts, you're going to hurt if you have those assets that are crashing. So let's say I'm right. We have a recession coming, and Nasdaq dropped by 85 percent in 2001. And we have a larger bubble this time, much larger. What is going to happen if the economy falls into a recession and we see Nasdaq crashing, in this AI bubble we have? I say Bitcoin, crypto, is a massive bubble. It doesn't take away that there is a technology just like in the locomotive, steam engine, and also what we saw with the radio and so on. But it's not the same as guaranteed returns. And I think we're going to see this in a not too distant future. It's a bubble that is going to burst. I think Warren Buffett and Charlie Munger are right. Bitcoin, crypto, is like a venereal disease. Thank you. (Applause)
