AI时代的经济学:劳动力份额、稀缺性与财富重分配 Dwarkesh Patel 2026-06-04

AI与未来稀缺性

主持人: 今天我要和Alex Imas以及Phil Trammell聊聊。Alex 是 Google DeepMind AGI 经济学的负责人,也是芝加哥大学的经济学教授。Phil 则是 Epoch 的经济学主管,同时也是斯坦福大学的访问学者。在这场访谈中,我大体上想了解的是,在一个自动化程度越来越高、AI 越来越先进的世界里,经济学告诉我们能期待些什么。我想了解这对工资和劳动力份额会有什么影响,对 AGI 创造的财富进行征税和重新分配的最佳方式是什么,以及哪些东西会变得稀缺。弄清什么是稀缺的,就能知道价值会聚集在哪里。我想从这里开始。在未来什么东西会稀缺,有哪些合理的候选选项吗?

Original English

Host: Today I'm chatting with Alex Imas, who is Director of AGI Economics at Google DeepMind and Professor of Economics at the University of Chicago, and Phil Trammell, who is Head of Economics at Epoch and research scholar at Stanford. In general what I want to understand in this interview is what economics tells us about what we can expect in a world with more and more automation and more advanced AI. I want to understand what that tells us about what will happen to wages and the labor share, what the best way to tax and redistribute the wealth generated by AGI will be, and what kinds of things will be scarce. What is scarce tells you where the value will accrue. I want to start there. What are some plausible candidates of what will be scarce?

Alex Imas: 比如“关系部门”(relational sector),它的定义是:在这类服务和商品中,有人类参与其中本身就是产品价值的一部分。因为人类天生是稀缺的,如果我们拥有了自动化技术,许多其他东西不再稀缺,但在那些有人类参与和介入的事情上,我们仍然会面临稀缺性。

Original English

Alex Imas: Something like the relational sector, which is defined as services and goods where the fact that a human was in the loop is part of the value of that product. Because humans are naturally scarce, if we have automation where a lot of other things stop being scarce, we will still have scarcity in the things that humans are involved in and in the loop for.

主持人: 我很好奇,人类为其他人类提供服务能否成为经济的重要组成部分。这里可能有一个直觉泵。在一个 AI 在物理上能做任何人类能做的事情的世界里,会有这样一个纯机器经济系统,它们在那里建造工厂、进行研究、提出新想法。在这些东西的物理生产过程中,人类可能参与也可能不参与,但如果机器人技术得到彻底解决,在最终极限情况下人类很可能是不参与的。如果你不在乎人类是否参与到那个过程中,那他们为什么还要参与呢?但就像你指出的,还有其他一些事情,我们确实希望芭蕾舞演员或咖啡师是真正的人类。这是去咖啡馆或看演出的部分价值所在。但只有人类才有这种偏好。因此,在这个“人类经济”中,人类在互相提供服务,并且他们的一部分财富流向了其他人类。但这部分财富也同时在向外流失,因为他们也会想要这个纯机器经济创造的一些自动化商品。这不是一个闭环。纯机器经济中的很多事情是一个闭环,因为机器不在乎让人类咖啡师给它们做杯咖啡。在这个模型下,“纯人类经济”将占据越来越小的份额,这难道不是其内在必然的吗?

Original English

Host: I'm curious to understand whether humans doing services for other humans can ever be a big part of the economy. Here's maybe one intuition pump. In a world where AI can physically do anything humans can do, there's this whole machine economy where they're building factories and doing research and coming up with new ideas. Humans may or may not be involved in the physical production of those things, but probably not in the ultimate limit, if robotics is solved. If you don't care about humans being involved in that process, why would they be? But then there are these other things you point out where we actually do want the ballerina or the barista to be a human. That's part of the value of going to a cafe or a performance. But only humans have that preference. So there's this human economy where humans are doing services for each other, and part of their wealth is flowing to other humans. But part of their wealth is also flowing out, because they will want some of the automated goods this machine-only economy is creating. This is not a closed loop. A lot of things in the machine-only economy are a closed loop because the machines don't care about getting the human barista to make them a coffee. Within that model, isn't it intrinsic that the human-only economy will become a smaller and smaller share?

Phil Trammell: 我想换一种方式来回答这个问题。我的观点是,像我们这样的经济学家做出的个人预测,作为单个预测来说并不一定非常有用。昨天有一篇由 Andrey Fradkin、Brian Jabarian 和 Andrew Koh 发布的博客文章,考察了经济学家对劳动力市场的预测。他们发现,大家的观点在各个方向上都存在着巨大的分歧。他们提倡的做法(我也同意这一点)是,我们不应该去思考个人预测,而是应该建立预测市场,在那里你可以获得聚合的预测和群体智慧效应。我认为这样做的原因是因为我们在预测方面出了名的糟糕。让我们一直追溯到 1820 年。我们现在进行的这场辩论实际上已经有 200 年的历史了。David Ricardo 是古典经济学家之一,不是新古典。当工业革命开始发生时,他写了很多东西说,“这对大家都会很棒。物价会降下来。” 但接着他话锋一转,说,“等等,我能看到所有这些创造价值的工作都将被这些机器自动化。这将会非常糟糕。每个人都会失业,还会出现政治动荡。” 而如果你看看 Ricardo 的预测,它们实际上是对的。在 Ricardo 那个时代所有能赚钱的工作都被自动化了。如果 David Ricardo 醒来,有人告诉他所有那些工作确实都被自动化了,然后问他:“你认为 2026 年的黄金年龄就业率是多少?”,我想当他被告知这个数字除了 2000 年之外是有史以来最高的时候,他会感到惊讶的。我们现在潜在可就业人口的就业人数是自 2000 年以来的最高水平。那是个峰值,现在基本上是第二个峰值。David Ricardo 最终忽略的是,存在结构性变化的经济学,那些被自动化的东西都变得便宜了。人们有了更多的钱去消费,然后他们开始把钱花在服务业上。

Original English

Phil Trammell: I would like to pitch a rephrasing of that question. My view is that the individual forecasts economists like us would make, as individual forecasts, are not necessarily very useful. There was a blog post by Andrey Fradkin, Brian Jabarian, and Andrew Koh that came out yesterday looking at economists' forecasts about the labor market. What they found is that there's a ton of disagreement in every single direction. What they advocate for, and I'm in agreement here, is that rather than thinking about individual forecasts, we should be generating prediction markets where you get aggregate forecasts and wisdom-of-the-crowd effects. The reason I think this is because we have been famously terrible at forecasting. Let's go all the way back to 1820. This debate we've been having is actually 200 years old. David Ricardo is one of the classical economists, not neoclassical. When the Industrial Revolution started happening, he wrote a bunch of stuff saying, "This is going to be great for everybody. Prices are going to come down." But then he turned around and said, "Wait, I can see all these jobs that are creating value are going to be automated by these machines. This is going to be really bad. Everybody's going to become unemployed, and there's going to be political unrest." And if you look at Ricardo's predictions, they're actually right. All those jobs that made money in Ricardo's time got automated. If David Ricardo woke up and somebody told him all those jobs did get automated, and then asked him, "What do you think the prime-age employment rate is in 2026?", I think he’d be surprised to be told it was the highest it's ever been other than 2000. We have the highest number of employed people that could potentially be employed since 2000. That was the peak and now it’s the second peak basically. What David Ricardo ended up missing is that you have these economics of structural change, where everything that got automated became cheap. People had more money to spend, and then they started spending it on services.

主持人: 这就是劳动合成谬误(lump-of-labor fallacy)。David Ricardo 没考虑到会创造出新的工作岗位。但钱会流向服务业这一点并不明显。为什么这些钱不会流向更多自动化商品之类的地方呢?

Original English

Host: This is the lump-of-labor fallacy. David Ricardo didn't consider that new jobs would be created. But it's not obvious that money would go to services. Why wouldn't it go to more automated goods and something like that?

Alex Imas: 我举这个轶事不是为了说这就是现在要发生的事,或者说我们将实现充分就业。我用它来是为了说明做预测是非常困难的。对于经济学家来说,一个可能有用的工具是转而从一个假设开始。也许我们今天开始假设:劳动力份额(labor share)为零。劳动力份额下降了。什么能解释这一点?让我们写一个关于发生了什么事情的经济模型。Phil 今天晚些时候会谈到这个。或者你可以写一个模型,问自己:“如果劳动力份额保持不变呢?什么能让这种情况发生?” 如果你从我的这场对话中什么都没带走,请记住这一点:我们没有任何数据。我一直在说我们需要一个针对数据收集的“曼哈顿计划”。我们没有关于消费者需求弹性的数据。我们不知道它们是多少。我们也没有真正去追踪哪些工作被创造或被摧毁了。包含了所有任务和各种职位的 O*NET 数据库更新极少,而且质量非常低。真正有用的是去思考潜在的情景,将它们描绘出来,并说明是稀缺性的哪个维度导致了每种情景的产生。如果是充分就业,我们就可以谈论关系部门。如果劳动力份额崩溃了,我们就可以讨论其他类型的情景。这将告诉我们应该去收集什么样的数据。

Original English

Alex Imas: I'm not using this anecdote to say this is what's going to happen now and that we're going to have full employment. I'm using it to say it's really hard to make predictions. What may be a really useful tool that economists have is to instead start with a premise. Maybe we start today: labor share is zero. Labor share has gone down. What could possibly explain this? Let's write down an economic model of what happened. Phil will talk about this later today. Or you can write down a model that asks, "What if labor share just stays the same? What can make that happen?" If you don't take anything else out of this conversation from me: We don't have any data. I've been saying we need a Manhattan Project for data. We don't have data on consumer demand elasticities. We don't know what they are. We're not really tracking what jobs are getting created or destroyed. The O*NET database, with all of the tasks and different jobs, has been rarely updated and is super low quality. What is really useful is to think about the potential scenarios, map them out, and say what dimension of scarcity will generate each scenario. If there's full employment, we can talk about the relational sector. If the labor share collapses, we can talk about other sorts of scenarios. That will tell us what data we should be collecting.

劳动力份额与资本的未来

主持人: 可能有必要快速定义一下劳动力份额(labor share)和资本份额(capital share)。整个经济体,也就是售出的商品和服务的总和,要么以工资的形式支付给人们,要么支付给资本,也就是说,有建筑物的租金,也有公司股东获得的分红。在过去几百年里,经济体中大约 60% 基本是以工资形式支付给了人类,剩下的 30% 到 40% 支付给了那些拥有机器、土地和公司索取权的人。问题在于,如果现在 60% 流向了工资,随着 AI 变得越来越聪明、越来越强大,这个比例会缩小吗?

Original English

Host: It's probably worth defining labor share and capital share real quick. The whole economy, the total sum of goods and services sold, is either paid out to people in wages or it's paid out to capital, which is to say, there's rent on buildings and shareholders of companies that get paid out. For many hundreds of years, ~60% of the economy basically gets paid out to humans in wages, and the other 30-40% gets paid out to people who own machines and land and claims on companies. The question is, if 60% is going to wages right now, does that shrink as AIs get smarter and better?

Alex Imas: 这是一个卡尔多事实(Kaldor fact)。我们应该强调这一点。在经历了工业革命以及我们所见过的所有自动化之后,这个数字仍然保持在 60% 以上,这是极其令人惊讶的。有些人担心它保持如此恒定是个会计核算上的错误。现在甚至还有争议。有些人可能会说,过去 20 到 30 年间劳动力份额一直在下降。但过去 30 到 40 年间的会计准则发生了很多变化。例如,Atkinson 有一篇论文表明,如果你在过去这些年里保持会计准则不变,劳动力份额甚至根本没有下降过。

Original English

Alex Imas: This is a Kaldor fact. We should stress this. It's incredibly surprising that it's over 60% after the Industrial Revolution and all of the automation we've ever seen. Some people are worried it's an accounting error that it's been so constant. There's even a controversy right now. Some might say labor share has been falling in the last 20 to 30 years. But there have been a lot of accounting changes in the last 30 to 40 years. For example, Atkinson has a paper showing that if you keep the accounting constant over the years, labor share hasn't even fallen ever.

主持人: 但这其实并不那么令人惊讶,对吧?Phil,你提出过这样的观点:如果劳动力和资本是互补的,做任何事情你都需要两者。那么你需要同时向两者支付报酬来完成某件事,这就说得通了。

Original English

Host: But it's not that surprising, right? Phil, you made this point that if labor and capital are complements, you need both to do anything. It would make sense that you'd need to pay both of them to get something done.

Phil Trammell: 虽然有些东西被完全自动化了,但从某种意义上说,目前还没有任何东西被彻彻底底地完全自动化。看看一种商品的“网络调整后的要素份额”。顺着供应链往下看,不仅要看最终的步骤,还要看资本和劳动力在其中做了多少,以及什么投入到了那些能够将最终步骤自动化的机器中。你会发现,劳动力在整个供应链下游增加了很多价值。美国的计算机和电子产品的网络调整后的资本份额非常稳定,大约在 50% 左右。它不是 100%。我确实认为我们都同意这种定性转变即将到来,那就是至少会有一些商品,其网络调整后的资本份额会变成 1。整个供应链都可以被自动化,而且其中没有哪个部分是我们本质上关心是否由人类来完成的。这将是一个定性的转变。有趣的是,这种转变对整体资本份额的影响是模糊的。假设我们有两个部门:像芭蕾舞演员那样具有人类本质属性的部门,以及其他所有东西。现在,因为缺乏劳动力,“其他所有东西”一直是稀缺的。但如果我们把其他所有东西的供应链完全自动化,并且我们对其他所有东西的需求极快地达到饱和,那么除了芭蕾舞演员之外所有东西的数量都会趋向于无穷大,但这些东西的边际效用趋向于零的速度比数量增加的速度还要快。

Original English

Phil Trammell: You have had stuff be completely automated. There's a sense in which nothing has yet been completely automated. Look at the network-adjusted factor shares of a good. Look down the supply chain and not just the final step and how much of that is done by capital and labor, but what went into the machines that can automate that final step. You'll find that labor is adding a lot of value down the supply chain. Computer and electronic products in the US have a very stable network-adjusted capital share of around 50%. It's not 100%. I do think there's this qualitative shift that I think we agree is coming, which is that there will be at least some goods whose network-adjusted capital share goes to one. The whole supply chain can be automated, and there's no part in it that we care intrinsically about having a human do. That will be a qualitative shift. Interestingly, the implications of that shift for the overall capital share are ambiguous. Let's say we've got two sectors: the human-intrinsic sector with the ballerinas, and everything else. Right now, everything else has been scarce because of the lack of labor in it. But if we fully automate the supply chains for everything else, and we satiate in everything else really fast, then the quantity of everything that's not a ballerina goes to infinity, but the marginal utility in that stuff goes to zero faster than the quantity is rising.

Alex Imas: 我也想稍微跳出芭蕾舞演员这个例子。我在我的文章中想要表达的观点——从一个特定情景倒推——是芭蕾舞演员和表演者选错了参照系。现在我们有很多包含不同任务的工作。这是基于任务的职位模型。以医生为例,他们的工作是什么?他们要填写保险文件。他们要去给不同的制药公司打电话。他们的任务之一是看病人和与病人交谈,但那不是工作的主要部分。你可以让一个工作、服务或商品成为不同类型任务的产物,你可以把其中一大堆任务自动化。如果消费者愿意为这样一种产品或服务支付更多费用:它的每一项任务都自动化了,只保留医生提供诊断和给予支持的那一个环节,我们就会把这种工作称为关系部门的一部分。人们愿意为了让人类留在这个工作环节中支付更多的钱。我们没有数据来说明,“这些是关系型工作,这些不是。” 你需要去收集下面这类数据。做个联合分析(conjoint analysis),评估你对这项服务或商品的支付意愿。这是一个反事实假设:一切都由机器生产。这是另一个反事实假设:只有一个任务不是由机器生产的。你的支付意愿是多少?你对于“人类不在环节中”的弹性是多少?如果我没有这些数据,我能在这个故事里做出什么预测?

Original English

Alex Imas: I also want to move away from the ballerina example. The point I was trying to make in my post—working backwards from a particular scenario—was that the ballerina and the performer are the wrong reference class. Right now we have a lot of jobs where you have different tasks. This is the task-based model of jobs. Take a doctor, what is their job? They're filling out insurance documents. They're going and calling different pharmaceutical companies. One of their tasks is to see the patient and talk to them, but that's not the main part of the job. You could have a job and a service or a good be a product of different types of tasks, and you can automate a ton of those tasks. If the consumer is willing to pay more for a product or service where every single task is automated except for that one part where the doctor is delivering the diagnosis and providing support, we would call that job part of the relational sector. People are willing to pay more for the human to stay in the loop in the job. We don't have data to say, "Here are relational jobs, here are not." You literally need to collect data of the following sort. Do a conjoint analysis of your willingness to pay for this service or good. Here's the counterfactual where everything is produced by machine. Here's the counterfactual where this one task is not produced by a machine. What is your willingness to pay? What is your elasticity for the human to not be in the loop? If I don't have that data, what prediction am I going to make in this story?

主持人: 是不是还有另一点,那就是还有很多完全自动化的商品根本还没存在?你现在也收集不到任何数据,比如说,对于某种完全由 AI 生产的能让你更健康的药物,人们会想花多少钱继续买得越来越多。

Original English

Host: Isn't there another point, which is that there are a lot of fully automated goods that don't even exist yet? And you can't collect any data right now about, say, how much people will want to keep buying more and more of some drug that makes you healthier that is fully produced by the AIs.

Alex Imas: 绝对是。这差不多就是 Phil 的观点。你可以让资本品的多样性增加,这样你就不会达到饱和状态。你增加了多样性,所以你不会碰上那种大部分收入都流向人类部门的边际效用递减点。如果那种多样性增长得足够快,而人类部门没有这种多样性的增加,那么你可以得到所有你想要的关系型商品,但这对劳动力份额来说无关紧要。它会降到零。

Original English

Alex Imas: Absolutely. That's kind of Phil's point. You could have an increase in variety in capital where you don't get the satiation. You're increasing variety, so you're not hitting that diminishing marginal utility point where most of your income is going to the human sector. If that increasing variety is fast enough, and there is no such increasing variety in the human sector, then you can get all of the relational goods you want, but it doesn't matter for labor share. It goes to zero.

主持人: Phil,我很喜欢你打的那个比方:如果 1400 年的时候有一个蒙古经济学家坐在那里思考什么会变稀缺,以及那种分析的局限性。我觉得你应该讲讲那个。

Original English

Host: Phil, I liked your analogy to some Mongolian economist sitting around in 1400 thinking about what will be scarce and the limits of that kind of analysis. I think you should talk about that.

Phil Trammell: 看看遥远过去的蒙古人能接触到的商品。我不是研究这个社会的专家,但我知道他们当时的多样性远不及我们现在。看看那些人类本质性的工作,比如做一名歌手。然后再看看那些非人类本质性的东西,比如他们的马匹提供的运输服务,或者是他们拥有的各种不同食物。如果他们仅仅固定这两个类别中的种类然后问自己,“一旦我们有了更多的自动化,会发生什么?”,他们可能会说,“我们很快就会对马一类的运输方式、酸奶和蒙古包感到满足。花在这些东西上的份额会变成零,最后我们只能把所有的钱都花在歌手身上。” 但当然,后来发生的事情并非如此。随着我们积累了更多的财富和更先进的机器,我们扩大了可以在歌手以外花钱的商品范围,而花在歌手身上的份额一直微乎其微。同样地,这也是我对未来如何展开的核心预测,尽管事情也可能走向另一个方向。

Original English

Phil Trammell: Just look at the goods available to a Mongolian of the distant past. I'm no expert on this society, but I know that they didn't have nearly the variety that we have now. Look at the jobs that were intrinsically human, like being a singer. And then you look at the things that were not intrinsically human, like the transportation services provided by their horses or the different kinds of food they had. If they just held the varieties fixed in both categories and asked, "What will happen once we have a lot more automation?", they might have said, "We'll just satiate in horse-like transportation and in yogurt and in yurts. Those shares will all go to zero, and we'll be left spending all of our money on singers." But of course, that's not what happened. As we've accumulated more wealth and more advanced machines, we've expanded the range of things other than singers to spend our money on, and the share spent on singers has stayed negligible. Likewise, that's my central prediction about how the future unfolds, though it could go either way.

主持人: 我本来想提出一个观点,但我意识到这是一个谬论,不过它是谬论的原因很有趣。很难想象这样一个世界:那里有数万亿个机器人,却只有几十亿人类,但我们花在机器人上的总钱数却少于我们付给 Magnus Carlsen 或者——

Original English

Host: I was going to make a point and I realize it's a fallacy, but the reason it's a fallacy is interesting. It's just hard to imagine a world where there are trillions upon trillions of robots, but there's only some billion-odd humans, and the cumulative amount we're spending on robots is less than what we're spending to pay Magnus Carlsen or—

Alex Imas: 财务顾问、医生或者辅导老师。

Original English

Guest: Financial advisors or doctors or tutors.

主持人: 对,或者是播客主播什么的。但我后来意识到为什么这是个谬论了。世界上晶体管的数量毫不夸张地说增加了万亿倍,也许是一千万亿倍。你的同事 Chad Jones 有一个非常有趣的发现,就是经济体中用来购买计算能力、购买晶体管的份额一直在下降。你提出的观点是,看待摩尔定律的一种方式是……什么决定了价格?供给和需求。所以不仅我们能更便宜地生产更多晶体管,而且边际晶体管的价值也在下降。就像你说的,摩尔定律的另一种说法是……我喜欢摩尔定律的这个悲观框架:每过 18 个月,计算的价值就减半。我们消耗计算用途的速度如此之快,以至于它维持了摩尔定律。这与关于 AI 的讨论息息相关,也许这是第一次,这种情况不再成立了。这里一个著名的现象是,现在租用一块 H100 的成本比三年前还要高,尽管我们现在有了先进得多的技术和世界上多得多的算力。因为随着模型变得越来越聪明,计算的隐性成本就变高了。这就是 Phil 关于增加多样性的观点。我们所做的,是增加了人们对资本所要求的事务种类。现在突然间你有了新的使用资本的多样化场景,于是价格又跳了回去。你可以想象我们对算力的需求永远不会饱和。只要情况一直如此,流向计算的经济份额就会持续增长。这是一个大问题。这是我们需要关注的终极问题。我们究竟在多大程度上为计算找到了大量能够产生需求的新用途?

Original English

Host: Right, or podcasters or whatever. But then I realized why it's a fallacy. The number of transistors in the world has literally trillion-X’d, maybe quadrillion-X’d. Your colleague Chad Jones has a very interesting result about how the share of the economy that is going towards paying for computing, paying for the transistors, has been decreasing. The point you made is that one way to think about Moore's law is… What sets price? Supply and demand. So not only are we producing more transistors more cheaply, but also the value of the marginal transistor is decreasing. As you were saying, another way of saying Moore's law is… I like the pessimistic framing of Moore's law: every 18 months, the value of computation halves. We're running out of uses for computation so fast that it's sustaining Moore's law. This is relevant to a conversation about AI where maybe for the first time, this is no longer true. The famous fact here is that an H100 costs more to rent now than it did three years ago, even though we have much superior technology and much more compute in the world. Because as models get smarter, the opportunity cost of compute gets higher. This is Phil's point about increasing variety. What we have done is increased the types of things that people demand from capital. Now all of a sudden you have a new variety that you could be using capital for, and you jump back up. You could imagine we just never satiate demand for compute. As long as that stays the case, the share of the economy that is going towards compute would keep increasing. That's the big question. That is the ultimate question that we need to be looking at. What number of new uses are we finding for that compute where you have the demand for these uses?

Alex Imas: 我想强调的是,经济学中的很多模型,特别是在我们正在讨论的这个领域里,都把需求当作外生变量。它们没有去剖析人们实际需求背后的心理机制。让我开始思考“关系部门”这个概念的,是我对一个事实所做的研究,即人类确实似乎存在这种内在价值。这不仅仅是因为稀缺,也是因为人们对共情、连接以及与另一个人互动有着某种内在的偏好。我们做过的一个实验是关于一件艺术印刷品的。我们用一种与激励相容的方式去问:“你愿意为这件艺术印刷品花多少钱?” 人们真的在为此支付真金白银。然后我们说:“听着,这种艺术印刷品只有一件,它要么是 AI 做的,要么是人做的。” 这些是受试者间条件。在一种情况下,你会发现人类制作的艺术印刷品估价远高于 AI 版本的。然后,在另一组条件下,我们说生产了 500 件。对于人类制作的那件,价格下降了很多,因为它不再被看作是与这位艺术家建立的一种连接。对于 AI 的来说,没有任何区别。AI 已经被视为一种商品了。我们需要对此进行更多的研究,但这似乎就是它和像马这样的东西之间的关键区别。马是对某种产出的一种投入,你可以用其他东西代替马。你只关心产出。这个关系的故事能够成立的唯一途径——也是我们需要更多数据的地方——是人类在“提供来自产出的价值”这个意义上不等于马,也就是说,如果你替换掉人类,产出的价值就会下降。如果这一点不够强烈,如果它不能适用于足够多的行业或足够多的工作岗位,那么这个故事就不再成立了。

Original English

Alex Imas: What I want to emphasize is that a lot of models in economics, especially in the space that we're talking about, take demand as almost exogenous. They don't unpack the psychology of what people actually want. What got me thinking about the idea of the relational sector is work that I was doing on the fact that there does seem to be this intrinsic value. It's not just because it's scarce; it's because there's some intrinsic preference that people have for empathy, connection, and interacting with another person. One of the experiments that we ran involved an art print. We have an incentive-compatible way of asking, "How much are you willing to pay for this art print?" People are actually paying real money for it. Then we say, "Look, there's only one of those art prints, and it's either made by AI or by a person." These are between-subject conditions. With one, you get the effect that the person-produced art print is valued much higher than the AI version. Then, in a set of other conditions, we say there's 500 of these being produced. For the human-made one, the price goes down a lot because it's no longer seen as making a connection with this one artist. With AI there's no difference. AI is already viewed as a commodity. We need to do a lot more research on this, but it seems that's the key difference between this and something like a horse. A horse was an input into an output, where you can replace the horse with something else. You only care about the output. The only way this relational story works—and this is what we need more data on—is if a human is not a horse in the sense that they are providing value from the output, where if you replace the human, the value of the output decreases. If that's not strong enough, and if it doesn't hold for enough sectors or enough jobs, then this story doesn't work anymore.

“混乱的中间期”与财富分配

主持人: (广告插播)很少有机构能像 Jane Street 那样,如此深入地思考如何将聪明人转变为世界上最能干的研究员和工程师。这在部分程度上依赖于学徒制模型,新员工会与资深导师结对。但 Jane Street 也开设了一系列课堂式的讲座和实操训练营。这些课程涵盖了一系列主题,而且讲得非常深。有一节课专门讲使用 strace 和 gdb 等工具对系统进行逆向工程,另一节课则教你如何把代码剖析到缓存层级。重要的是,Jane Street 设计这些课程不只是为了教授相关的对象级技能,也是为了传授相关的隐性知识。比如,他们为期一周的神经网络训练营从一般理论开始,然后迅速过渡到如何将神经网络应用于交易。在这里他们会涵盖 Jane Street 员工容易遇到的具体障碍,以及他们想出来的绕过这些障碍的解决办法。Jane Street 非常重视这类学习。每个办公室都有专门的教室空间,课程被作为日常工作的一部分被优先对待。如果你想在这样的地方工作,Jane Street 正在招聘。你可以到 janestreet.com/dwarkesh 查看他们的空缺职位。

有一条 Molly Kinder 写过关于“混乱的中间期”(Messy Middle)情景的可能性。那种可能性让我思考,是不是——至少在财富分配和重分配方面——经历一次更快的 AI 起飞会更好。我想问你们,以下这种可能性是否哪怕有一丁点可能,或者有没有任何一组假设能让它成立:AI 使自动化工作成为可能,导致许多人失业,但在这个自动化发生的过程中,它并没有创造出足够的财富,来补偿那些被解雇的人,从而创造一种帕累托改进,即每个人都因为 AI 自动化而变得更好。当然,在某种平庸的意义上,这必定是真的。公司因为不用支付人类薪水而是只支付给 AI 所节省下来的任何钱,这些资源依然存在于经济体中,可以直接分发给人们。但是会存在一些分配上的低效。政府并不知道到底谁是因为 AI 而被解雇的。这存在政治问题。如果 Meta 的员工最先被解雇,而他们一年的收入是 200,000 美元,那么在还有许多劳动者收入远低于这个数字的情况下,你每年给他们发 200,000 美元的支票,这种情况在政治上是可持续的吗?你觉得这种情景合理吗:AI 自动化了很多东西,但创造的财富却不如自动化的程度那么多?

Original English

Host: There aren't that many institutions that have thought as hard as Jane Street about how to turn smart people into some of the most competent researchers and engineers in the world. This relies in part on an apprenticeship model, where new hires are paired with senior mentors. But Jane Street also runs a bunch of classroom-style lectures and hands-on bootcamps. These courses cover a range of topics and they go pretty deep. There's one lecture that focuses on reverse engineering systems with tools like strace and gdb and another that teaches you how to profile code down to the cache hierarchy level. Importantly, Jane Street designs these courses not just to teach the relevant object level skills. but also to impart the relevant tacit knowledge.

There's one possibility which Molly Kinder has written about, this "Messy Middle" scenario. That possibility made me think about whether it might be better to have—at least as far as wealth distribution and redistribution go—a much faster AI takeoff. I want to ask you whether the following possibility is at all likely, or if there's any set of assumptions that can make it so. AI makes it possible to automate jobs such that many people are losing their jobs, but it doesn't create enough wealth, while the process of automation is happening, to basically pay off the people who are getting laid off and create a Pareto improvement, where everybody's getting better as a result of AI automation. Of course, there's a trivial sense in which that must be true. Whatever money the company is saving by not paying the humans instead of just paying the AIs, those resources still exist in the economy and can just be paid out to people. But there's going to be some allocative inefficiency. The government doesn't know exactly who got laid off because of AI. There's a political problem. If the Meta worker gets laid off first and they were making $200,000 a year, is there a politically sustainable situation where you give them a $200,000 check a year when there are many working people making much less? Do you find this scenario plausible, where AI is automating a bunch of things, but there isn't as much wealth creation as there is automation?

Phil Trammell: 我认为有可能。在我看来,这确实像是一个相当狭窄的窗口期。我的猜测是,如果我们拥有了自动化如此多工作的技术,以至于它成了一个新的政治问题,那么(经济)这块蛋糕也会增长得非常快。

Original English

Phil Trammell: I think it's possible. To me, it does seem like a pretty narrow window. My guess is that if we have the technology to automate so many jobs that it becomes a new kind of political problem, then the pie will also be growing really fast.

主持人: 嗯,除非在它自动化的所有那些专业里,它的生产力只是微乎其微地提高了一点点。因此,用来替代所有软件工程师的所有资本成本,只是比我们付给软件工程师的成本稍微少一点点。为什么一家公司通过解雇一批软件工程师来省钱是不合理的呢?而且从长远来看,会存在杰文斯悖论(Jevons paradox),我们无法提前预见有了更多软件我们会做什么,肯定会有更多的用处。但在短期内,影响仅仅是许多人被解雇了,而他们仍然需要弄清楚如何才能利用多出一百万倍的 JavaScript token。

Original English

Host: Well, unless in all of those professions it's automating, it's just a hair more productive. So the cost of all the capital to replace all the software engineers is just a hair less than the cost of what we've been paying the software engineers. Why is it implausible that a company can save money by laying off a bunch of software engineers? And in the long run, there's a Jevons paradox, and we can't anticipate in advance what we'd do with more software, and surely there will be more uses. But in the short run, the effect is just that a lot of people are laid off, and they still need to figure out how they can use a million times more JavaScript tokens.

Alex Imas: Phil 和我一直在写关于这些事情的文章,在这些事情背后我们有数学模型。我们目前所有模型中都没有政治经济学的部分。Andy Hall 写过一篇非常好的关于 AGI 政治的博客文章,他做了一个非常有趣的观察。如果失业率增加 2%,政治风向就会完全改变。失业对政治局势有着巨大的影响。说到 Molly 那篇出色的文章,我认为在某种程度上,由于政治经济因素的影响,“缓慢渗透”(drip)情景是最糟糕的情况之一。你可能会看到人们并没有真正大规模失业,而是进入了付给他们更少钱的行业。这就是 1920 年到 1940 年间电话接线员身上发生的事情。电话接线员被完全取代了,但这花去了 20 年时间,尽管当时技术已经存在。这其中有一个缓慢滴流的过程。并不像是一整个巨大的行业凭空消失了。这方面有一篇很棒的 QJE(《经济学季刊》)论文显示,他们被经济体重新吸收了,但工资更低,并且主要是处于不充分就业状态。那就是 Molly 文章中所写的情景,在这个混乱的中间期,事情并不是一场彻底的灾难。我们在应对新冠疫情时看到,如果出现了紧急情况,财政响应可以行动得非常迅速。失业率快速上升就是一种紧急情况,这种上升甚至看起来只有 2-3%。如果它发生得很快,那就会成为国家紧急状态。令人担忧的是,无论你在那些白领身上省下了什么钱,如果这并没有使经济增长,而只是创造了可以分配到其他地方的被节省下来的资源,那这足够实施一个基础广泛的重新分配计划吗?你手里只有从少数几个人身上省下来的钱。除非你能弄清楚具体如何把这笔钱准确交到他们手上,否则你会面临这样的问题:“我能用解雇员工省下的钱来发 UBI(全民基本收入)吗?” 你的意思其实是蛋糕并没有扩大多少。你只是替代了一群人,但这并没有拓展经济生产能力的技术前沿。这里还有一个问题:历史上每次发生这种情况时,技术前沿是否都得到了极大扩展?我认为事实如此。简单看看历史,技术前沿是扩大了的。我觉得 Phil 也表达了同样的观点。很难想象会存在那样一种情景:你获得的智能刚好足以取代软件工程师,但仍然要花很多钱。它的成本只是比软件工程师便宜那么一点点,因此你没有获得这种丰饶效应(abundance effect)。既然蛋糕没有做大,财富再分配要从哪里来?

Original English

Alex Imas: Phil and I have been writing about these things, and we have mathematical models in the back of these things. We don't have any political economy in any of our models. Andy Hall wrote a really nice blog post about the politics of AGI, and he made a really interesting observation. If there's a 2% increase in unemployment, the political winds completely change. Unemployment has a huge effect on what happens politically. Referring to Molly's excellent essay, I think in some ways one of the worst scenarios is a drip scenario because of the political economy piece. What you might see is people not really being unemployed en masse, but moving into sectors that pay them less money. This is what happened with phone operators between 1920 and 1940. Phone operators were completely automated, but it took 20 years, even though the technology existed. There was this drip. It wasn't like this giant sector just disappeared. There's a really nice QJE paper on this showing that they got reabsorbed into the economy, but at lower salaries, and they were mostly underemployed. That's the scenario Molly was writing about, this messy middle where things aren't a disaster. We saw with COVID that the fiscal response can move quickly if there's an emergency. An emergency is a quick uptick in unemployment, which could even look like 2-3%. That becomes a national emergency if it happens fast. The concern is that whatever you're saving on those white-collar workers, if that's not growing the economy but just creating saved resources that can be allocated elsewhere, is that enough to do a broad-based redistribution scheme? You have the money you've saved off a couple of people. Unless you can figure out exactly how to get it to them specifically, you have the problem of, "Can I do a UBI off the money I saved by laying off…?" You're basically saying the pie did not grow that much. You're just displacing a bunch of people, but that didn't grow the technological frontier of what the economy can produce. Then there's a question of whether every time this has happened in history, the technological frontier has expanded a bunch. I think that's the case. Simply in history, the technological frontier has expanded. I think Phil made the same point. It's hard to imagine that sort of scenario where you are getting intelligence that's just enough to replace the software engineer but still costs a lot of money. It's just a hair less expensive than the software engineer, so you're not getting this abundance effect. Where is the redistribution going to happen because the pie didn't grow?

主持人: 这非常有帮助。如果要让这种情景成真,就必须同时满足很多不同的条件,而每个条件看起来都不太可能。其一,它必须满足:有可能实现整个白领工作的自动化,但这只是一种零碎的自动化。也就是说,你只能让软件工程师自动化,但同一个程序却不能同时让会计、分析师等等的工作自动化。我认为智能的运作模式是——无论是像软件工程这样的工作所涉及的广泛任务,还是智能本身的本质——如果你真的能解雇所有软件工程师,说明你的“智能池”里已经积累了足够的能量,你可以让各种白领工作都实现自动化。这些裁员能省下巨额开支,而且 AI 会比人类劳动力便宜得多。如果这两点都成立,这种我们真的拿不出财富来分配的“混乱的中间期”情景看起来就不太可能发生了。随之而来的问题是,对它进行征税和重新分配的最佳方式是什么?

Original English

Host: This is very helpful. Many different things have to be true for this scenario to come to pass, each of which seem unlikely. One, it has to be the case that it is possible to automate entire white-collar jobs, but only in a piecemeal way. That is to say that you can only automate software engineers, but that same program can't also automate an accountant and an analyst and whatever. My model of intelligence is such that—both the breadth of tasks it requires to do something like software engineering and what intelligence is—if you can really just lay off all the software engineers, you've got enough in the bucket there that you could automate all kinds of white-collar work. There are huge amounts of potential savings that have happened as a result of these layoffs, and also AI is going to be cheaper than human labor. If both of those things are true, this messy middle scenario where we literally don't have the wealth to go around seems unlikely. Then the question is, what is the best way to tax it and redistribute it?

Alex Imas: 我有些想法。我觉得列出成本和收益是非常重要的。首先,实施这些措施时的复杂性存在差异。其次,它们在真正发挥作用的时间线上存在差异。像“全民基本资本”(universal basic capital)这样的东西,是不会在六个月内就对发生的事情产生回报的。你最后可能会采取分层叠加的措施。比如,以负所得税为例。你实施它,在它成为法律的那一天,你已经获得了一份保障:设置了一个底线,每个人都能拿到一定数量的钱,如果你赚了更多的钱,就会被征更多的税。但负所得税有利也有弊。以 UBI(全民基本收入)为例,我非常担心其政治经济学的影响。如果人们只是依赖一张支票,那么谁掌权就变得非常重要了。现在,我们被赋予了可以转化为收入的劳动力。当情况不再如此,我们在满足基本需求上要受制于民选官员的恩赐时,这感觉像是一种非常危险的权力分享安排。

Original English

Alex Imas: I have some thoughts. I think it's really important to outline the costs and benefits. First, there's differential complexity in implementing these things. Two, they differ in the timeline of being actually helpful. Something like universal basic capital is not going to generate returns for something that happens in six months. You probably are going to end up with a layer of things. Take a negative income tax, for example. You implement it, and the day it turns into law, you already have this insurance that there's a floor where everybody gets a certain amount of money, and if you earn more money, you get taxed more. But there are positives and negatives to a negative income tax. With UBI, for example, I worry a lot about the political economy implications. If people are just dependent on a check, it really matters who's in power. Right now, we're endowed with labor that can turn into income. When that is no longer the case and we are at the mercy of the elected official for basic needs, that feels like a power-sharing arrangement that's really dangerous.

主持人: 但是,政府的任何财富再分配项目不都是如此吗?

Original English

Host: But wouldn't that be true of any sort of government redistribution program?

Alex Imas: 如果是“全民基本资本”这种形式,你就拥有资本的所有权份额和财产权,你只是拥有一个份额而已。你是一个普通的股东。你就是一个普通人。

Original English

Alex Imas: With something like universal basic capital, where you have an ownership share and property rights for capital, you just have a share. You're a normal shareholder. You're just a normal person.

主持人: 但这又回到了指数化投资(indexing)的问题,因为如果很难进行指数化投资,那么全民基本资本也很难实现。

Original English

Host: But this goes back to the question of indexing, because if indexing is hard, then universal basic capital is hard.

Alex Imas: 那确实是全民基本资本的问题:标的选择。你选择什么目标资产放进人们的投资组合里?

Original English

Alex Imas: That's the problem of universal basic capital: targeting. What do you target to put into people's portfolios?

主持人: 比如,如果 Anthropic 归零了,而某个不知名的机器人公司接管了这一切怎么办?

Original English

Host: Like, what if Anthropic goes to zero, but some random robotics company takes all this over?

Alex Imas: 完全正确。那就是全民基本资本的风险。对于负所得税,你也会遇到和 UBI 一样的问题,某个上台的人说,“我们不再搞这个了”,人们又不能去工作,然后你就面临着保障底线消失的问题。对于财富税的一个担忧是,在 0.5% 的财富税水平下,并不存在政治上可持续的平衡状态。这当然曾在所得税上发生过。一开始很低,可能是为了打仗什么的,然后慢慢水涨船高,直到美国的边际所得税率达到 40% 左右,而在某些州,这一比率高达 50% 以上。

Original English

Alex Imas: Exactly. That's the risk of universal basic capital. With a negative income tax, you have the same sort of issues as with UBI, where somebody comes into power and says, "We're not going to do that anymore," and people can't work, and then you have the issue of the floor being gone. One concern with the wealth tax is that there's no politically sustainable equilibrium at a 0.5% wealth tax. This happened with the income tax, of course. It starts low, it’s for war or something, and then it slowly escalates until the marginal income tax rate in the US is on the order of 40%, and in certain states, upwards of 50%.

主持人: 对资本征税的话,有理由担心它会扭曲投资吗?人们会不会觉得,“我为什么还要投资 Anthropic 或英特尔呢?政府要拿走越来越大的份额,稀释我的股份。”

Original English

Host: With a capital tax, is there a reason to worry that it would distort investment? Would people just say, "Why would I invest in Anthropic or Intel? The government is going to take larger and larger shares of it and dilute my share."

Phil Trammell: 等等。我们应该把资金如何筹集、征税对象是谁以及如何分配这些问题分开来看。有可能是政府通过实施基础广泛的税收,然后买下 Anthropic 的股票分发给每个人。

Original English

Phil Trammell: Hold on. It's worth separating how the revenue is raised, what's taxed, and how it's distributed. It could be that the government hands out shares of Anthropic to everyone by a broad-based tax and then buying Anthropic.

主持人: 这可能是正确的做法。希望一些民粹主义的提议不要干预这个过程,不要去剥夺那些恰好大家都知道的某家特定公司的财产。你这是在暗示可能会有某种最优的税收政策。我们正在对外部性征税,或者对土地征税。我想我们可能需要对这两者以外的东西征税。或者是消费税。

Original English

Host: Which would probably be the right thing to do. Hopefully, some populist proposal doesn't interfere with that and expropriate some particular company that everyone happens to know about. You're suggesting there could be some sort of optimal tax. We're taxing externalities or we're taxing land. I guess we probably need to tax something other than just those two things. Or consumption.

Alex Imas: 好吧,消费税,比如欧洲的增值税,允许政府去买一堆股票,然后他们把这些股票发给每个人。这就是 David Autor 的……

Original English

Alex Imas: Ok, a consumption tax, like a European value-added tax, allows the government to go buy a bunch of stocks, and then they just distribute those stocks to everybody. That's David Autor's...

Phil Trammell: 那和直接重新分配股票不会有太大区别,但还是会有一点不同。

Original English

Phil Trammell: That's not going to be that different from just redistributing the stocks, but it will be a little different.

Alex Imas: 顺便说一下,那曾经是有关社会保障体系的一项提议。那就是社会保障体系的私有化。到目前为止它一直在运转,但是关于它还能运转多久,存在着疑问。社会保障私有化基本上就是给每个人一篮子股票。

Original English

Alex Imas: That was the proposal for Social Security, by the way. That was privatizing Social Security. It's worked so far, but there are questions about how long it's going to keep working. Privatizing Social Security was basically giving everybody a basket of stocks.

AI与就业:现实还是叙事?

主持人: 人们都在谈论现在是不是已经迎来了白领的末日。有什么证据表明目前已经出现了由 AI 导致的大规模自动化或失业吗?

Original English

Host: People talk about whether there's a white-collar apocalypse already. Is there any evidence that suggests there is mass automation or unemployment as a result of AI already?

Alex Imas: 很多人都在关注这个问题。这个领域有很多双眼睛在盯着,而且正在产生大量的数据。耶鲁大学的 Budget Lab 正在对此进行非常好的分析。他们最近发布了一份报告,你必须眯起眼睛才能看到发生了什么变化。如果你纵观整个经济体,甚至去审视软件工程这些暴露程度最高的行业,其实也没有什么事情发生。可能有一点点初级开发人员获得的工作比以前少了的信号。但那是“比以前少”,而不是一种层次上的转变,这意味着实际上对高级软件工程师的需求反而是增加了。如果你看整体趋势的话,对初级开发人员的需求确实略低于之前的趋势线。

Original English

Alex Imas: A lot of people are looking at it. This is an area where there's a lot of eyes and a lot of data being produced. The Budget Lab over at Yale is doing really good analysis on this. They just recently released a report, and you really have to squint to see anything happening. If you want to take an approach across the entire economy, even looking at software engineering, the most exposed sectors, there's just not really anything going on. There might be a little bit of a signal about junior developers getting jobs less than before. But that's a "less than before" rather than a level shift, as in there's actually an increased demand for senior software engineers, if anything. If you look at the trend, for junior developers, it's a bit below trend.

主持人: 所以你是说,哪怕对于入门级软件工程师而言,现在的增长确实比以前慢了,但仍然是在增长的。你怎么看待那些快毕业的大学生都在说他们觉得找 CS 方面的工作越来越难的传闻呢?

Original English

Host: So you're saying the growth is slower than before, but there is still growth even for entry-level software engineers. What do you think is going on with the anecdotal evidence of graduating college students saying that they're finding it harder to find CS jobs?

Alex Imas: 我觉得那些都只是轶事而已。

Original English

Alex Imas: I think that's anecdotal evidence.

主持人: 你认为对某些人来说找工作一直都挺难,而现在只不过是把它包装成了关于 AI 的叙事?关于裁员也是一样,可能只是正常的裁员,却被包装成了“因 AI 裁员”。

Original English

Host: You think it's always been hard to get jobs for some people, and now it's getting turned into an AI narrative? Same with the layoffs, where it's probably just a normal layoff, and they turned it into an AI layoff.

Alex Imas: 你必须对这一切保持谨慎。存在一些作为公共协调装置的因素。假设我们陷入了这样一种叙事:如果你作为一家公司没有裁员,那么你就会被认为对 AI 的适应性不够。这将会引发一种级联效应,各个公司为了在起步裁员这件事上随大流,不得不相互跟风。那是非常令人担忧的:这家公司在裁员后的处境可能比裁员前更糟,但它只是为了制造一种印象而裁员,“看,我们没有落后于时代。我们在使用 AI。” 你可能听说过关于“计数 token”的轶事,他们被要求最大化 token 数量之类的事情。眼下,我们并没有任何关于白领大屠杀的证据。

Original English

Alex Imas: You have to be careful with all of this. There are these public coordination devices. Let's say we get into a narrative where if you're a firm and you're not laying people off, then you're seen as not adapting AI enough. Then you're going to just get a cascade effect of firms needing to keep up with the Joneses in terms of starting to lay people off. That's super worrying, where the firm might actually be worse off after the layoffs than before, but it's just doing the layoffs to have the perception that, "Look, we're not behind the times. We're using AI." You probably heard these anecdotal stories of token counters, where you have to maximize tokens and things like that. Right now, we don't really have any evidence of a white-collar bloodbath.

主持人: 考虑到 AI 能做的所有这些事情,这是否让人感到惊讶?

Original English

Host: Is that surprising at all, given all these things AI can do?

Phil Trammell: 这是个老生常谈的故事了。如果你把某些互补性任务自动化了,那么整个事物组合——那些与自动化形成互补的人类劳动——的价值就会上升。在这个论点中,一个极其重要的数据是需求弹性。以工作的“O型环模型”为例。一项工作就是一系列任务。假设 AI 自动化了十项任务中的九项。有一项任务没有被自动化。如果那个人现在可以专注于那一项任务,这项工作的生产力就会提高。如果这转化为一种价格效应,也就是产品实际上变得更便宜了,而且如果需求做出了足够的反应,买的人更多、服务用得更多了,那这实际上可能会导致更多的招聘。互联网上很多人都在非常普遍地阐述这个论点,他们说,“看,从数据上看如果说有什么的话,我们在软件工程方面的需求是增加的。” 这表明至少在目前,考虑到工作运作的模式,需求可能是具有足够弹性的。我认为这个需求弹性的论点非常重要,它是很多人提出的论点,或者只是很多人在不理解潜在因果关系时所使用标签的基础。大家经常谈论杰文斯悖论(Jevons paradox)。这个观点是,当某样东西变得更便宜时,你会想要如此之多,以至于你花在这个东西上的总金额增加了。众所周知,大约 200 年前英国的煤炭就发生过这种情况。但这实际上只有在某样东西的需求具有高度弹性时才会发生。有很多东西并没有那么高的弹性需求。比如,如果石油变得超级便宜,情况也不会像施了魔法一样——

Original English

Phil Trammell: This is a story as old as time. If you automate some complementary task, the overall bucket of things—the human labor which complements the automation—will increase in value. One of the statistics that's really important for that argument is elasticity of demand. Take the O-ring model of jobs. A job is a series of tasks. Let's say the AI automates nine out of ten tasks. One task is not automated. If that person can now focus in on that task, the job will become more productive. If that translates into a price effect where the product is actually cheaper, and if demand responds enough where it's being bought more and the service is being used more, that could actually lead to more hiring. A lot of people on the internet have been making that argument very generally, saying, "Look, if anything in the data, we're seeing an uptick in software engineering demand." Which suggests that at least for now, given the way that jobs work, it might be elastic enough. I think this elasticity of demand argument is incredibly important for a lot of arguments that people make, or just a lot of labels that people use without understanding what the underlying causation is. People often talk about Jevons paradox. This is the idea that as something gets cheaper, you will want so much more of it that the total amount you spend on the thing increases. Famously, this happened to coal in Britain ~200 years ago. But really this only happens if the demand for something is highly elastic. There are many things for which there is not super elastic demand. If oil, for example, gets super cheap, it's not like magically—

主持人: 或者是胰岛素。

Original English

Host: Or insulin.

Phil Trammell: 没错。不会像施了魔法一样突然多出那么多汽车,让我们现在使用的石油比以前多得多。

Original English

Phil Trammell: Exactly. It's not like magically there's going to be so many more cars that now we're going to be using way more oil than before.

主持人: 至少在短期内不会。

Original English

Host: At least not in the short run.

Phil Trammell: 确实。长期弹性要高于短期弹性。但即使在长期来看,农业就是一个众所周知的例子,如果我们把过去投入到农业的相同经济份额现在依然投入其中,我们可以生产出多得多的食物。无论如何,我们现在已经生产出了更多的食物,但如果 100 年前负责生产食物的经济份额拿到现在来,我们可以生产得更多。但你只要吃饱了,这就结束了。而关于软件的论断是,随着它变得更便宜,你会想要越来越多,这并不是市场的某种内在属性。关于软件的关键在于它是一种特殊类型的商品,它越便宜,我们想要的就越多。

Original English

Phil Trammell: Exactly. The long-run elasticity is higher than short-run elasticity. But even in the long run, agriculture famously is the example where we can produce way more food if we dedicated the same portion of the economy that we dedicated to agriculture in the past. We're already producing more food regardless, but we could produce even more if the same portion of the economy that was producing food 100 years ago was currently producing food. But you eat enough, and then you're done. The claim with software is that it is not some inherent property of markets that as it gets cheaper, you'll just keep wanting more of it. The thing about software is this is a particular kind of good where as it gets cheaper, we'll want more and more of it.

情景规划与经济负增长的谬误

主持人: 这也高度相关,你曾就此写过一篇文章——这期播客很大程度上就是我把你的文章总结后反馈给你。Citrini 有一篇在网上非常火的关于未来的情景预测,预测由于自动化和非常强大的 AI,将会出现经济衰退。白领工人将被自动化取代,他们拿不到薪水了,因此会出现经济衰退。你想再概括一下为什么这可能是不合理的吗?

Original English

Host: It is also highly relevant, and you wrote an essay about this—a lot of this podcast is me summarizing your essays back to you. There's this very viral scenario planning about the future by Citrini, predicting that as a result of automation and very powerful AI, there will be a recession. White-collar workers will get automated, their salaries will no longer be available, and so there will be a slump. Do you want to recapitulate why this might be implausible?

Alex Imas: 它有一部分是合理的,一部分是不合理的。我们谈话一开始提到的那部分就是合理的,即可能会出现大量失业。如果自动化速度很快,人们可能会被解雇,而且他们可能无法很快找到新工作。我们可以对 Citrini 文章中关于失业的部分进行商榷,但这并不是问题的关键。问题在于他们谈论了经济负增长。在我和 Phil 进行过交流的那篇文章里,我所做的就是说:让我们从经济负增长这个命题开始。你需要在经济中具备什么样的条件才能获得负的经济增长?事实证明这些条件是非常不可能的。你需要的一点是,资本的所有者,也就是富人们……基本上在那些情景中发生的事情,是财富和收入从利用其劳动力的低收入群体重新分配给了科技资本的所有者。所以你需要需求是有边界的,像一个硬性界限,甚至不是那种温和的敏感度递减。你需要他们最终说:“我已经赚够了。我不想再花任何钱了。” 并且这笔钱不能作为投资进入市场。然后你才能得到负增长。最关键的一点是,即使我们不想买更多东西了,在一个存在技术奇点并且我们竟然不想投入更多资金的世界也是疯狂的。我们没有说:“让我们建更多的数据中心吧。让我们建更多的晶圆厂吧。” 尽管我们拥有了 AGI,我们却没有投资于更多的数据中心来运行 AGI,从而推动更多的经济增长。我把那篇文章发给了 Phil,Phil 回信说:“这挺蠢的”,说的是我的文章。他说:“你想说将会出现经济负增长,但这些是非常不合理的条件。” 而我的回答是:“这就是这篇文章的重点。这些确实是非常不合理的经济条件。” 这正是情景规划真正发光的地方。比如 Citrini 的那篇文章,它写出来是很棒的一件事,因为它开启了对话。这种想法太直观了:如果需求崩溃,我们就可能让经济萎缩。你可以在大萧条(Depression)中看到这一点。在大萧条中,技术前沿并没有扩展。但在今天,技术前沿正在扩展。你其实拥有了丰饶(abundance)。要让丰饶导致经济负增长,这是很难做到的。

Original English

Alex Imas: Part of it is plausible, part of it's not. The part that we started the conversation with is the idea that there could be a lot of unemployment. If the speed of automation is quick, people could get laid off, and they may not find work very quickly. We can quibble about the unemployment part of the Citrini essay, but that's not the issue. The issue is that they talked about negative economic growth. What I did in the piece, that Phil and I had a back and forth on, was to say, let's start with the proposition that there's negative economic growth. What conditions do you need in the economy to get negative economic growth? It turns out the conditions are pretty improbable. One thing that you need is for the holders of capital, rich people basically… Basically what you have in those sorts of scenarios is a reallocation of wealth and income from lower-income people who are using their labor towards tech capital owners. So you need demand to be bounded, like a hard bound, not even a soft diminishing sensitivity. You need for them to eventually say, "I've had enough. I don't want to spend any more money." And for that money to not enter as investment. Then you can get negative growth. The crucial thing is, even if we don't want more shit, the world in which there's a singularity and we don't want to invest more money is crazy. We're not saying, "Let's build more data centers. Let's build more fabs." Even though we have AGI, we're not investing in more data centers to run the AGI and that's driving more economic growth. I sent the essay to Phil, and Phil wrote back being like, "This is pretty dumb," like my essay. He said, "You're trying to say that there's going to be negative economic growth, but these are very implausible conditions." And I was like, "That's the point of the essay. These are very implausible economic conditions." That's where scenario planning really shines. You have the Citrini essay, which was great that it was written because it started a conversation. It's so intuitive, this idea that if there's demand collapse, we can get the economy to shrink. You could get that with a depression. In the Depression, the technological frontier didn't expand. Here, the technological frontier is expanding. You actually have abundance. For abundance to generate negative economic growth, that's really hard to get.

主持人: (广告插播)Google 最近发布了 Gemini Omni,它的视频编辑能力令人难以置信。你可以上传一段视频,然后告诉 Omni 改变背景、调整光线,或者添加、删除元素。所有这些操作都能在保持其他一切事物连贯的同时完成。但 Omni 也不仅仅是一个视频编辑器。我有机会和 Omni 背后的研究及产品团队坐下来聊了聊,我了解到它是对未来前沿模型训练方式的一种预演。它可以接收任何类型的输入,不管是文本、音频还是视频。尽管它目前还没有这样做,但在架构上它是可以直接无缝输出图像或文本的。所以这确实是对多模态数据迁移假说(multimodal data transfer hypothesis)的一次押注。模型通过观察其他类型的数据,变得更善于预测某一种特定类型的数据。例如,Omni 非常擅长在视频上精确渲染文本,尽管 Google 并没有在这个模型中刻意将这种能力作为目标。并且 Omni 是迈向更精确世界模型(world models)的下一步。因为为了预测视频的下一帧,你必须对物理规律和空间动力学有深刻的理解。随着 Omni 的进步,看看它能否缩小仿真与现实的差距(Sim2Real gap)将会非常有趣。因为在现实世界中收集数据比在模拟环境中困难得多,机器人技术的进展已经落后于 AI 的其他应用。但如果你有能够模拟现实的极佳的视频模型,也许这种情况就会发生改变。与此同时,如果你想尝试 Omni,你可以在 gemini.google 的 Gemini 应用程序中查看它,或者在 Google 的人工智能创意工作室 Flow (flow.google) 中使用它。

我们刚才讨论了为什么目前没有因为大语言模型而出现更多的自动化。正如你提到 O型环理论(O-ring theory)时所说,有一个合理的机制可能是这样的……O型环理论指的是挑战者号航天飞机因为一个部件发生故障而爆炸,摧毁了整个航天飞机。也许那构成了经济体中商品如何生产的一个更通用的模型。你必须确保一切都是可靠且良好运转的。所以你现在还不能把一份完整的工作自动化给 AI。尽管它有可能以某种概率去完成这项任务,但你需要它具备极高的可靠性,以保证它不会毁掉最终成品。这也许解释了为什么现在的自动化程度远低于理论上可能达到的程度。但我认为,一旦 AI 变得足够先进,情况就会朝相反的方向发展。将人类融入未来产品的生产流程中将变得非常困难。甚至撇开关于人类会更昂贵或能力较弱的论点不谈,未来将会出现完全为 AI 劳动力组织的整个生产流程。它们用“神经语”(neuralese)交流。它们的思考速度快了好几千倍。因此,即便存在某种比较优势,雇佣人类是合理的,交易成本以及对可靠性的担忧,也会使得人类很难被整合到未来的生产流程中。

Original English

Host: Google recently announced Gemini Omni and its video editing capabilities are incredible. You can upload a video and then tell Omni to do things like change the background or adjust the lighting or add or remove elements. All while keeping everything else consistent. But Omni isn't just a video editor. I got a chance to sit down with the research and product team behind Omni and I learned that it's a preview of how future Frontier models will be trained. It can take in any kind of input, whether that's text or audio or video. And while it doesn't currently do so, architecturally it's capable of just seamlessly outputting images or text. So it's really a bet on the multimodal data transfer hypothesis. The model becomes better at predicting one data type by seeing the others. For example, Omni is really good at accurately rendering text on video, even though Google didn't specifically target that capability in this model. And Omni is the next step towards more accurate world models. Because in order to predict the next frame of a video, you have to have a deep understanding of physics and spatial dynamics. As Omni progresses, it'll be interesting to see whether it can close a Sim2Real gap. Because it's much harder to collect data in the real world than it is in simulation, robotics progress has lagged other applications of AI. But if you have really good video models that can simulate reality, maybe that stops being the case. In the meantime, if you want to try Omni, you can check it out in the Gemini app at gemini.google or use it in Google's AI Creative Studio, Flow, at flow.google.

We were talking a second ago about why there isn't more automation as a result of LLMs. One plausible mechanism could be, as you were saying with the O-ring theory… O-ring theory refers to the fact that the Challenger shuttle blew up because one component malfunctioned, and it destroyed the whole thing. Maybe that's a more general model of how goods are produced in the economy. You have to make sure everything is reliable and works well. So you can't automate an entire job to an AI right now. Even though it might be able to perform it at some probability, you need extreme reliability in order for it to not destroy the finished good. This might explain why there's a lot less automation now than there otherwise could be. But I think it works in the other direction once AIs get advanced enough. Integrating humans into the production flow of future goods will become difficult. Even beyond the arguments about how humans will be more expensive or less capable, there will be whole production flows organized for AI labor. They're talking in neuralese. They're thinking many thousands of times faster. So even if there's some comparative advantage where it makes sense to hire a human, there will be transaction costs and worries of reliability that will actually make it hard to integrate humans into future production flows.

Phil Trammell: 我觉得这说得很对。我要特别区分一下这一点:如果你把一项工作的十分之九自动化了,人们可能会转移到那剩下的十分之一上,但现在要求他们完成的工作量可能会达到原先的十倍。可以拿它和最近 Gans 和 Goldfarb 提出的 O型环自动化模型比较一下。如果你只能将这项工作十分之九的部分自动化,但完成的质量标准低于人类,你可能连那十分之九都不想自动化。这部分完全可以平移过来。同理,这也可能是为什么我们不再在工作的哪怕十分之一的环节上雇佣人类的原因:因为人类的表现在质量或速度上就是无法达到 AI 在其他部分工作中的水平。他们最终反而会拉低最终成品的质量或速度。

Original English

Phil Trammell: That seems right to me. In particular, I just want to distinguish between the point that if you automate nine-tenths of a job, people might shift over to the last tenth, but there might be ten times more work demanded of them. Compare that to the model of O-ring automation from Gans and Goldfarb recently. If you can only automate nine-tenths of the job, but you do it to a lower standard of quality than the human could, you might not want to automate even those nine-tenths. That's the thing that could totally port over. Symmetrically, it could be a reason why we don't use a human for one-tenth of the job anymore, because a human just can't perform it to the level of quality that the AI can perform the other parts of the job, or the level of speed. They end up pulling down the quality or speed of the finished product.

主持人: 顺便说一下,你所说的这个模型对我来说极具说服力,它解释了为什么更多的律师、会计师,甚至软件工程师还没有被自动化取代。在某些情况下,你完全可以确信这个东西确实能按预期运行,但你付钱给律师的原因是:“我需要这层保障,确认我的公司真的不会因为某些原因而破产——”

Original English

Host: By the way, the model you're talking about seems extremely plausible to me for why more lawyers, accountants, or even software engineers are not automated. There are cases where there's a pretty good probability that the thing worked as you expect, but the thing you're paying the lawyer for is: "No, really, my company's not going to go under because—"

Alex Imas: 你也是在为许多跟合规相关的事宜付钱。特别是对于律师行业,你需要某个实体来为产品背书。你需要拥有产品的所有权。你需要有人能够行使解雇或雇佣的权力,这其中还有执照发放的问题。许多监管层面的要求同样会让人类留在业务环节中——即使其中不存在任何人际关系因素——这些要求与人类实际执行该服务的能力毫无关系。

Original English

Alex Imas: You're also paying for a lot of regulation-type stuff. With lawyers particularly, you need some entity to back up the product. You need ownership of the product. You need somebody to be able to fire or hire, and there are licensing issues. There's a lot of regulatory layers that are also going to be keeping—even if there's no relational element—humans in the loop that have nothing to do with the ability of the human to actually perform the service.

Phil Trammell: 在诸如立法、担任法官、担任陪审员等这些我们习惯于只信任人类来进行的政治类决策上,以及使得特定职业保持由人类担任的所有执照要求上,所有这些摩擦在我看来都只是过渡性的。我们对人类有何期许、我们如何组织我们的政治,在整个历史长河中已经发生过很多次改变,从小型狩猎采集群体到庞大帝国等等。一旦一套由 AI 运行的政治体系比其替代方案高效得多时,这套体系可能会倾向于在竞争中淘汰掉其他体系。

Original English

Phil Trammell: All of these frictions on the political-type decisions that we are accustomed to only trusting humans for—legislation, being a judge, being a juror, or all the licensing that keeps certain professions human—that all strikes me as transitional. What we expect to come from a human and how we organize our politics has changed so many times throughout history, from little hunter-gatherer bands to empires to whatnot. Once an AI-run political system is much more efficient than the alternatives, those will probably tend to out-compete the others.

AI实体偏好与未来的资源分配

主持人: 说到这儿,我们一直在谈论人类目前拥有什么偏好,以及这会对未来哪种商品变稀缺产生什么影响。但当然了,未来我们将会面对各种不同的实体:人工智能。曾经有一段时间地球上还没有人类,但是进化选择出了拥有特定驱动力和偏好的个体,因为那些特质最有利于生存,而这些偏好如今决定了在这个规模达一百万亿美元的世界经济体中生产什么。为什么不指望未来在 AI 身上发生同样的事呢?这甚至都不是一个出现灾难性对齐失败从而屠杀所有人类的世界。但会出现一种进化,即便不是个体 AI 自身的进化,那也是将 AI 作为其一部分的公司的进化。这种进化会偏好什么?它可能偏好能够成长的公司或代理。有一个基于选择机制的论点指出,那些不断成长的实体将变得更为普遍。也许单凭这一点,你就可以对它们的偏好做出一些预测。那种偏好拥有“人类内在固有商品”的实体,会成为最能积攒资源的实体吗?可能不会。它可能更喜欢储蓄,并且对任何相关的资源有着无法满足的需求。算力就是一个显而易见的例子。我们能不能用它来对那些将指引未来的非人类偏好做出一些预测?

Original English

Host: Speaking of which, we've been talking about what preferences humans currently have and what impact that has on what kinds of goods will be scarce in the future. But of course, we'll have different kinds of entities in the future: AIs. There was a time when there were no humans on Earth, but evolution selected for agents that have specific drives and preferences because those tend to survive the most, and those preferences now determine what a hundred-trillion-dollar world economy produces. Why not expect the same thing from AIs in the future? This is not even a world with catastrophic misalignment, where they just kill everybody. But there will be evolution of, even if not individual AIs, firms which have AIs as part of them. What will that evolution favor? It will probably favor firms or agents that grow. There's a selection argument that things which grow will be more prevalent. Maybe just based on that, you can make some predictions about what their preferences will be. Is the kind of entity which prefers to have human-intrinsic goods going to be the kind of entity that accumulates resources the most? Probably not. Probably it saves more and has unsatisfiable demand for whatever the relevant resource happens to be. Compute is an obvious one. Can we use that to make some predictions about the non-human preferences that will be guiding the future?

Alex Imas: 如果有一个 AI 拥有它自己的福利,是完全自主的,并且在做出与其福利相关的决定,老实说,我绝对没有“它会偏好与人类打交道”这样的先验假设。完全没有理由。但我还是从这个论点的另一面来分析一下吧。人类偏好于彼此互动,比起一个模拟的 AI,人类更偏向于去信任其他人类并与他们产生共情,我认为这些偏好是否会改变,是一个非常重要的问题。我听到过很多论调说:“瞧,我们现在只是不习惯这种技术。你所认为的这种关系上的需求……到了某个时刻,人们只会把 AI 治疗师看作一种更高级的产品,他们不再需要由人类来提供的那种共情了。” 我觉得这实际上是一个极其复杂的问题。这里有一个可以证明它不会消失的理由,它和进化有关。假设世界上有两种人。其中一种人并没有这种执念。他们完全可以只和 AI 交流,或者任何能给出更好模拟的东西都行。另一种人身上则几乎具有一种道德情感——用 Jonathan Haidt 的框架来说——他们抵制将此类社交互动外包给 AI。这两种人中,哪一种人更会去繁衍后代,寻找配偶,去干所有这些事情?我想答案是很明确的。是那第二种对其他人有偏好的人。

Original English

Alex Imas: If there's an AI that has its own welfare, is fully autonomous, and is making its own decisions that are welfare-relevant, to be honest, I have absolutely no prior that it would prefer to deal with humans. There's no reason. But let me take the other side of that argument. Humans' preferences to be interacting with one another, to trust and empathize with other humans versus a simulated AI, I think it's a really important question whether those will change. I've heard a lot of arguments saying, "Look, right now we're just not used to the technology. What you’re thinking of as relational… At some point, people are just going to see an AI therapist as a superior product, and they're not going to need the empathy that the human is providing." I think this is actually a really complicated question. Here's one argument for why it's not going to go away, and it has to do with evolution. Let's say there are two types of people. One person doesn't really have this preference. They can just interact with an AI, whatever can simulate it better. The other one has almost a moral emotion—using Jonathan Haidt's framework—against offloading those sorts of social interactions to an AI. Which of those two people are going to reproduce, find a mate, all of these sorts of things? I think the answer is clear. It's the second one that has the preference for other people.

主持人: 这取决于繁殖是如何发生的。

Original English

Host: Depends on how the reproduction is happening.

Alex Imas: 确实。但如果我们处在一个繁殖仍然以目前这种方式发生的世界里,我认为……这是一个大问题,我不是在做预测。你曾在节目上邀请过 David Reich。他在上期播客中的观点是,我们依然处于自然选择的活跃期。因此即使你现在可能看到某种冷漠的态度,自然选择可能依然会将我们推向对其他人类拥有更强烈的偏好。

Original English

Alex Imas: Fair. But if we're in the world where reproduction is still happening the way that it's happening, I think… And this is a big question, I'm not making a prediction. You had David Reich on the show. His point on the last podcast was that we're buzzing with natural selection. So even if you get some sort of indifference now, you might get selection to point into an even stronger preference for other humans.

主持人: 有一种思考这个问题的方式是这样的。世界上最富有的人的财富是如何变现的?我们早些时候通了个电话,你指出他们的消费更多是偏向于关系型商品的。比如 Mark Zuckerberg 雇了 MMA 教练和舞者来参加他妻子的生日派对,等等。但他大部分财富就是 Meta 的股票。作为控股股东,他可以说:“Meta,把所有这些财富变成股息收入,我只把它们全花在消费上。” 相反,他更愿意让他的财富复利增长,让 Meta 建造更多的数据中心。所以甚至不需要人类发生改变就会出现这种情况。最富有的人——由于财富在复利增长而越来越富有——恰好带有这种几乎类似于尼克·兰德(Nick Land)式的、想要加速资本增长的偏好。这似乎说明了,这正是决定未来生产何种物品的一个重要决定因素。

Original English

Host: Here's one way to think about it. How is the wealth of the richest people in the world instantiated? We were having a call earlier, and you made the point that their consumption is more geared towards relational goods. Like Mark Zuckerberg is hiring MMA instructors and dancers for his wife's birthday, and so forth. But most of his wealth is just stock in Meta. As a controlling shareholder, he could say, "Meta, turn all this wealth into dividend income, and I will just spend that on consumption." Instead, he would rather have his wealth compound and have Meta build more data centers. So you don't even have to change humans for this to be the case. The humans who are wealthiest—and growing wealthier because their wealth is compounding—just have this almost Nick Landian preference for accelerating capital. That does seem to suggest that this is an important determinant of what kinds of things are produced in the future.

Phil Trammell: 在这两种人——偏好人类心理医生的人,和完全能够适应与 AI 互动的人——之间出现差异,可以从两方面来解释。如果他们在对资本品的满足感上饱和得一样快,但喜欢人类心理医生的人也恰好喜欢享有某些人类本质性的服务,那么在未来,资本的边际价值与今天的资本边际价值相比,如果在起初两人同样富有的情况下,对他们两人而言基本应该是相同的。当然其中可能会有一些交互作用之类,但基本上应该是相同的。如果导致差异的原因是其中一人对资本根本不觉得饱和,因为他们受到探索宇宙和把自己的大脑变成一个宇宙超级大脑前景的吸引,而另一个人感到满足了,那么对资本不感到饱和的那个人,如果是理性的,就会有更高的储蓄率。所以在长期来看,他们将拥有大部分财富,整体的资本份额基本就变成了这个人的支出的资本份额,也就是等于 1。很重要的一点是,我们谈论的并不是某个假想的未来。Elon Musk 正在谈论在月球上建质量加速器。他是世界上目前为止最富有的人。显然,他目前的投资既投向人类也投向了机器,但我认为他并不特别在乎他未来的研究员和工程师是人类还是 AI。

Original English

Phil Trammell: There are two ways you could get the two kinds of people, one of whom prefers a human therapist and one of whom is fine interacting with the AI. If they both satiate equally quickly in capital but the one who likes the human therapist also just likes having some human-intrinsic services, then the marginal value of capital in the future, compared to the marginal value of capital today, for each of them if they start out equally rich, should be basically the same. There could be interactions and whatnot, but basically, that should be the same. If what's driving the difference is that one person just doesn't satiate in capital because they're engaged by the prospect of exploring the universe and turning their head into a galaxy brain or whatever, and the other one satiates, then the person who doesn't satiate in capital is going to, if they're being rational, have a higher savings rate. So in the long run, they're going to have most of the wealth, and the overall capital share will basically be the capital share of that person's spending, which is going to be one. It's important that we're not talking about a hypothetical future. Elon Musk is talking about mass drivers on the moon. He's by far the wealthiest person in the world. Obviously, currently his investments are going towards humans as well as machines, but I don't think he cares particularly that his future researchers and engineers are humans versus AI.

主持人: 而且他繁衍后代的速度也很快。所以我认为划清这个界限是值得的。现在有一些富人似乎对资本很难快速饱和,所以也许长远来看他们会存下最多的钱。

Original English

Host: And he manages to reproduce fast as well. So I just think it's worth drawing that distinction. There are currently some rich people that don't seem to satiate quickly in capital, and so maybe in the long run they'll save the most.

Phil Trammell: 我觉得这是对的。我也想说,即使他们在生物学上繁殖的速度较慢,如果他们能长生不老,那可能在长远来看也根本没什么关系。

Original English

Phil Trammell: That does seem right to me. I would also say, even if they do reproduce more slowly biologically, that might just not matter that much in the long run if they can live forever.

Alex Imas: 长生不老是关键。重申一下,我们在这里是在构建情景模型。如果你能永远活下去,对我的推论来说很多事情也会改变。关于你说的有钱人不怎么消费而去投资的观点,这一切都取决于资本的回报率。现在,数据中心的回报率超高,但如果我们陷入人们对资本感到饱和的情况,那么积累资本的回报率就会下降。那么这些富人就会增加消费,因为投资的动机变小了。基本上,你可以思考一下这类过程的一般均衡……自 1820 年以来,我们变得极其富有。越来越多人开始投资,但同时你也获得了一种消费反应,这种反应让人们保持在就业状态并使劳动力份额居高不下。那是因为——

Original English

Alex Imas: The living forever is key. Again, we're scenario-building here. If you could live forever, a lot of stuff changes for my story as well. To your point about rich people not consuming a lot and investing, this will all depend on the returns to capital. Right now, the returns to data centers are super high, but if we get into a situation where people are satiated with capital, then the returns to accumulating capital are going to be lower. Then these rich people are going to be consuming more, because the incentive to invest is smaller. Basically, you think about the general equilibrium of this sort of process… We have gotten tremendously richer since 1820. Many more people are investing, but you're still getting a consumption response which keeps people employed and labor share high. That's because—

主持人: 等等。

Original English

Host: Hold on.

Phil Trammell: 等等,不一定。我觉得你可能在表达同样的观点。可能的情况是他们的投资必须经过实际劳动者的参与才能发挥作用。

Original English

Phil Trammell: Wait, not necessarily. I think you're probably making the same point. It could be that their investment has to be titrated through actual laborers who have to do things for their investment to work.

Alex Imas: 在未来,只有消费是通过人类来调节的,对吧?因为投资可以完全由机器人完成。

Original English

Alex Imas: In the future, only the consumption is human-mediated, right? Because the investment can just be done by the robots.

Phil Trammell: 所以我们现在讨论的是如何保持高劳动力份额的情景。让我们来看看那种情况。在那个保持了高劳动力份额的情景下,无论出于什么原因,资本的回报率都会更低。

Original English

Phil Trammell: So we're in the scenario of how you can keep high labor share. Let's take that scenario. In the scenario with high labor share, for whatever reason, the returns to capital are going to be lower.

主持人: 没错。回到之前我们说“混乱的中间期”不合理的那个点,我觉得我们在这里可以采用类似的分析。如果我们要让资本的回报率变低,经济增长率就必须得低,对吧?这肯定比我们在这个转化型 AI 发展期间预期的要低。如果出现了爆炸性的增长……

Original English

Host: That's right. To the earlier thing where we were saying why the messy middle is implausible, I feel like we can do a similar thing here. For our returns to capital to be lower, the growth rate has to be lower, right? It certainly has to be lower than what we're expecting through the period of transformative AI. If there's explosive growth…

Phil Trammell: 是也不是。资本存量可能会快速增长,但资本品相对于消费品的价格下降的速度可能比资本存量增长的速度还要快。

Original English

Phil Trammell: Yes and no. The capital stock could grow quickly, but the price of capital goods relative to consumption goods could be falling faster than the capital stock is growing.

Alex Imas: 这就是潜在技术前沿与这些东西实际变现价格之间的差异。因为存在相对价格。

Original English

Alex Imas: It's the difference between the potential frontier of technology and the realized prices of these things. Because you have relative prices.

主持人: 所以你的意思是,我可能会把钱用来赚取 30% 的利息,去投资数据中心等等。如果在未来增长率很高,就会出现一些获得高回报的东西。或者,由于所有这些技术突破,市场上出现了一些我很想立刻买的酷炫产品,这两者都会成为很有吸引力的选择。

Original English

Host: So you're saying I could be putting my money towards earning 30% interest and investing in data centers, or whatever. There will be something in the future, if the growth rate is high, that earns high returns. Or, as a result of all these technological breakthroughs, there's some cool product that I really want to buy right now, and both of those will be compelling options.

Phil Trammell: 是的。也不一定非要是新产品。它可以是一种具备人类本质性的产品。不过,如果这是一种人类本质性的产品,我们在未来对它的渴望肯定会比现在多得多,因为它与之比较的对象是——

Original English

Phil Trammell: Yeah. It doesn't have to be a new product. It could be a human-intrinsic product. Although, if it's a human-intrinsic product, we would want to have it much more in the future than we want it now, because the thing it compares against is—

主持人: 我们对它的渴望可能和现在一模一样,在这种意义上:我们从芭蕾舞表演中获得的边际效用与现在完全相同。但是我们从机器人那里获得的边际效用可能比现在要低得多。所以,如果以“机器人”为单位来衡量,我们想要的远比现在多得多。

Original English

Host: We might want it the same as we want it now in the sense that the marginal utility in a ballerina performance is exactly the same as now. But the marginal utility in a robot might just be a lot lower than now. So in units of robots, we want it a lot more than we want it now.

Alex Imas: 利率会是 30% 吗?

Original English

Alex Imas: Would the interest rate be 30%?

Phil Trammell: 那取决于你指的实际利率是什么。情况可能是现在的一个机器人能在明年变成 100 个机器人。所以,如果以机器人为单位计算,利率就是 10,000%。但是如果机器人的价格下降得非常快……

Original English

Phil Trammell: It depends what you mean by the real interest rate. It might be that every robot now can turn into 100 robots next year. So in units of robots, the interest rate's 10,000%. But if the price of robots is falling really fast...

Alex Imas: 价格会自我调整。我想这才是重点。在这里,价格正在以一种许多宏观经济模型无法容纳的有趣方式进行调整。正在发生的是所谓的特指投资的技术变革。资本品相对于消费品的价格正在下跌,而不是像标准宏观经济学那样,把“产出”看成一个虚构的综合体,认为产出可以按一比一的比例分配给资本或消费。在未来的世界里,那将不再成立。明年每一单位的资本所换取的消费,要远少于今年每一单位资本能换取的。

Original English

Alex Imas: Prices adjust. I think that's the whole point. Here prices are adjusting in this interesting way that too many macro models don't allow for. What's happening is what would be called investment-specific technical change. The price of capital is falling relative to the price of consumption, instead of doing the standard macro thing of saying there's just output, this chimera of a thing called output, which one for one can be allocated to capital or consumption. That's not going to be true in this world. Every unit of capital next year is giving up way less consumption than each unit of capital this year.

主持人: 现在的一个机器人明年会变成好多个机器人,但芭蕾舞演员的数量保持不变。

Original English

Host: One robot now turns into many robots next year, but the number of ballerinas is the same.

Phil Trammell: 再次强调,我们要回到“多样性增加”这一点上。如果明年所有的额外机器人实际上代表了不同种类的机器人,而且我对这些机器人并没有感到饱和,那么情况就会截然不同。不过现在我们讨论的是消费领域。

Original English

Phil Trammell: Again, we're going to go back to the increasing varieties thing. If all of those extra robots next year are actually different varieties of robots and I'm not getting satiated on those robots, then it's a very different story. But now we're talking about the consumption world.

主持人: 对于投资端来说,只要出现一个极其贪婪、总想要更多机器人的商业巨头就够了。单凭这一点,就足以提高机器人的边际价值,进而降低劳动力份额?

Original English

Host: For the investment side of things, there could be just some greedy titan of industry who keeps wanting more and more robots. That alone would be enough to increase the marginal value of robots and therefore decrease labor share?

Phil Trammell: 是的。

Original English

Phil Trammell: Yes.

主持人: 为什么我们不期望那些极其贪婪的商业巨头继续存在呢?历史上的商业大亨都建造了图书馆以及——

Original English

Host: Why are we not expecting greedy titans of industry to keep existing? Greedy titans of industry historically have built libraries and—

Phil Trammell: 但那是因为他们死去了,他们会想——

Original English

Phil Trammell: But that's because they die, and they're like—

主持人: 哦,他们都会死。每个人都会死。

Original English

Host: Oh, they all die. Everybody dies.

Phil Trammell: 嗯,走着瞧吧。

Original English

Phil Trammell: Well, we'll see.

主持人: 在人们终有一死的前提下……你曾请过一位嘉宾上节目,他说要了解未来就该去思考过去。未来可能会有新型巨头诞生,他们积累财富的目的仅仅是为了积累财富。但在大部分情况下,至少在历史上,积累财富的过程是同龄人以及所在社群内部大型社交互动的一部分,在这个过程中,你渴望以某种方式赢得他人的赞赏。关于这些商业大亨的一贯描述是,他们积累了资本,然后大买特买。

Original English

Host: Conditional on people dying… You had a guest on the show who said to understand the future, you should think about the past. You could have new types of titans being born whose entire reason for accumulating wealth is just to accumulate wealth. But a lot of the time, at least historically, the wealth accumulation process is part of a large social interaction amongst peers, amongst the community, where you want to be admired in some way. The stylized fact of titans of industry is you accumulate the capital, and then you buy a bunch of stuff.

Phil Trammell: 这是一个历史遗留问题,不过在我看来似乎在很多情况下,事实是当他们临近生命终点时,他们要么把财富传给子孙,而这些子孙作为资本的管理者往往不如他们出色。后代们甚至都无法使财富随经济的增长率而增长,更别说跑赢经济增长的速度,也就是他们父母当年的业绩了。他们会想:“比起由我继续玩这场累积财富的游戏,我其实不太在乎孩子们能否拥有它。所以我要直接把它交给某个信托基金。” 如果人类的寿命变得更长,或者如果他们能想出某种法子把他们的信托基金与这套财富累积过程彻底挂钩……感觉这里的进化力量简直太强了。只需要几个有着这种思维的个体,这就能成为决定整个经济体偏好的主导力量,因为这部分的增长速度比经济体中的其他部分快得多。

Original English

Phil Trammell: I guess this is a historical question, but it does seem to me that in a lot of cases what is happening is that as they near the end of their life, they either hand it off to their children, who are worse stewards of capital than they are. They don't even manage to grow their wealth at the rate the economy grows, much less faster than the economy grows, which their parents were doing. They're like, "Well, I care less about my children having it than me playing this game of accumulating wealth. So I'm just going to give it to some trust." If people are living longer or if they can figure out some way to align their trust to this wealth accumulation process… It just feels like the evolution here is so strong. You just need a couple of agents that think this way for this to be the dominant thing determining the preferences of the whole economy, because this part is growing much faster than the other parts of the economy.

Alex Imas: 刚才不断有人提到饱和点和边际效用递减的话题,我觉得这非常关键。如果一个人有一种对于累积财富的内在偏好,那就是他们唯一想要的,那么我认为你的观点是完全对的。但这通常不是偏好的运作方式。当你生命中的享乐达到一定程度时,社会地位就会占据主导地位……卢梭写过这方面的论点,圣奥古斯丁也探讨过。这是偏好的一个基本组成部分。现在,你们争论的是另一回事:即使只有那么一两个特例,由于他们的财富高度集中,这点力量就足以改变一切。对此我无话可说。

Original English

Alex Imas: The part about satiation and diminishing marginal utility keeps coming up, I think it's really important. If a person has an intrinsic preference for accumulation, that's just what they want, then I think your story is totally right. But that's just not how preferences usually work. You have enough hedonics in your life, and then the social status… Rousseau wrote about this, St. Augustine wrote about this. This is a basic part of preferences. Now, you guys are arguing about something else, where you could have such high concentration that you could just have a couple of exceptions to the rule, and that's going to be enough. I have nothing to say about that.

Phil Trammell: 我想这个主张还要更进一步:不仅仅是你可能遇到一些特例,而是我们在历史以及今天都清楚地看到了这些特例。他们之所以没有在历史上控制整个经济体,是因为发生了所谓的“耗散冲击”(dissipation shocks)。他们把财富传给挥霍无度的孩子,或者放进那些把钱花掉的基金会。

Original English

Phil Trammell: I think the claim is a little stronger, not just that you could have some exceptions, but that historically and today we see the exceptions. They just haven't really taken over the economy historically because there have been these dissipation shocks, as they're called. They've given it to their kids who squandered it, or they put it in foundations which spent it.

Alex Imas: 这其实算不上什么冲击,但是……

Original English

Alex Imas: It's not really a shock, but…

Phil Trammell: 这些人也许会希望让全宇宙都布满属于他们的纪念碑,然后永远富足地活下去。这是种很奇怪的偏好,但这不是一种假设。我认为这才是我们主张的核心。

Original English

Phil Trammell: People might have liked to fill the universe with monuments to themselves and live forever, very wealthy. It's a weird preference, but it's not a hypothetical preference. I think that's the claim.

Alex Imas: 但谁知道他们脑子里在想什么呢?

Original English

Alex Imas: But who knows what's going on in their heads?

Phil Trammell: 即使没有对累积的内在偏好,还有一些工具性的理由让一些人看重财富累积,这也是值得指出的。他们渴望在政治、哲学或宗教层面的影响力。人们在社会长什么样以及大众应该相信什么这方面陷入了军备竞赛。与此类似却又不同的一种情况是纯粹的功利主义慈善,因为它不是一场军备竞赛。作为一个优秀的古典功利主义者,当我思考为什么在未来拥有巨额财富可能是件好事时,对我而言,它的价值——或者至少能解释为什么在未来拥有财富会成为一种几乎无法满足的效用函数的原因——在于去创造出新的快乐生命。这些生命只不过是为世界增加了整体的福祉。这种想法至少可以追溯到 Bostrom 关于“天文级浪费”(astronomical waste)的观点:我们可以在恒星周围建造戴森球,将所有能量转化为极度快乐的模拟世界等等。我认为这个优化器具体贪婪与否并不重要,重要的是他们渴求什么。

Original English

Phil Trammell: Even without the intrinsic preference for accumulation, there are some instrumental reasons why some people might value accumulation, which is also worth bringing up. There's a desire for political, philosophical, or religious influence. People get into an arms race over what society looks like and what people believe. Similarly but differently, because it's not an arms race, there's just total utilitarian philanthropy. When I think about why it might be good to have a lot of wealth in the future as a good classical utilitarian, to me, the value—or at least one way you could have an almost unsatiating utility function in having wealth in the future—is to create new happy beings. They just add to the total welfare of the world. This idea goes at least as far back as Bostrom's astronomical waste point, that we could put Dyson spheres around the stars and turn all the energy into really happy simulations and whatnot. I think the particular greediness of this optimizer doesn't matter, what they're greedy for.

主持人: 抛开功利主义哲学或者诸如此类的想法,一个纯粹的冯·诺依曼探测器(von Neumann probe)有着……我不知道这么说准不准确。它们对它们将占领的任意随机恒星系有着极高的边际价值判定,因为那会转化为更多受控制的恒星系。一个冯·诺依曼探测器是一种可能存在的东西。那是一个极端贪婪的优化器。如果我们讨论它们是否会主宰经济体,这也许是一个技术细节。但是我们在计算 GDP 时,只算最终的消费品和投资品。如果出现下面这种现象——

Original English

Host: Forgetting about utilitarian philosophy or whatever, a pure von Neumann probe has… I don't know, is this an accurate way to say it? They just have high marginal value for the random solar system they'll occupy because that turns into more solar systems. A von Neumann probe is a thing that can exist. That's a very greedy optimizer. If we're talking about whether they'll dominate the economy, maybe this is a technicality. But we only count final consumption goods and investment goods as GDP. If there's just this phenomenon—

Alex Imas: 一个冯·诺依曼探测器要如何体现在 GDP 中呢?

Original English

Alex Imas: How does a von Neumann probe show up in GDP?

主持人: 没错。如果我们承认它是一个属于自己的“人”,并且它在决定到底是花点钱在“婴儿版”冯·诺依曼探测器上去殖民另一个星系,还是用来雇芭蕾舞演员时处于优化权衡的边缘状态,而它压根不怎么在乎芭蕾舞演员……当我们讨论 AI 生命体时,情况完全取决于我们在这种情况下如何进行会计核算。在一个可能存在冯·诺依曼探测器的世界里,这个世界到底是什么样的?劳动力份额有可能居高不下吗?

Original English

Host: Exactly. If we recognize it as a person that owns itself, and it's optimizing on the margin between spending a bit more on a baby von Neumann probe that colonizes another star system or a ballerina or something, and it just doesn't value the ballerina very much… When we're talking about AI beings, it just completely depends on how we're doing the accounting there. What does the world look like in a world where von Neumann probes are possible? Is it possible labor share is high?

Phil Trammell: 以我们通常的核算方式,我认为这有可能保持高劳动力份额。

Original English

Phil Trammell: I think it's possible the labor share is high the way we usually count it.

AI时代的全球应对与分化

主持人: (广告插播)目前在强化学习中最大的问题之一是学分分配,因为存在非常长的执行路径(rollout),你必须知道它们成功或失败的原因。Cursor 的研究员 Sasha Rush 曾在黑板上给我上了一课,讲解他们如何运用带文本反馈的有针对性的 RL 来解决这个问题并训练出了 Composer 2.5。这是我用 iPhone 拍的,所以请原谅画面质量。 Sasha Rush:所以我们生成了这个输出。这只是一连串的 token。我们要把这一串 token 发送给这个去读取它的模型,然后模型会圈出它认为有问题的某一步。然后我们就要进行文本编辑了。我们就取那个执行轨迹,然后真的直接强行往里塞些额外的 token。 主持人:在 Cursor 注入了这些提示性 token 之后,他们会进行另一次前向传递。执行轨迹本身没有变,但提示使得模型降低了分配给那些错误 token 的概率。然后 Cursor 训练原始模型来匹配那些概率,这基本上就是在教它降低这些特定错误的权重。这里还有很多细节我们在中插广告里放不下。如果你想看完整版,我已经把它发到我的 Twitter 上了。如果你想试试 Composer 2.5,去 cursor.com/dwarkesh 吧。

经济学家们对于那些不在 AI 生产链上的国家有什么建议吗?如果你既不生产 AI 模型,又不生产进入 AI 模型的硬件设施,如果你不是在制造 HBM 内存的韩国,或者有晶圆厂的台湾地区,又或者是有 ASML 的荷兰。印度或者尼日利亚,他们现在应该怎么做?如果此时此刻你在跟莫迪(Modi)谈话,你会对他说什么?

Original English

Host: One of the biggest problems in RL right now is credit assignment because you have these extremely long rollouts and you need to know why they succeeded or failed. One of Cursor's researchers, Sasha Rush, gave me a blackboard lecture on how they use targeted RL with textual feedback to deal with this problem and train Composer 2.5. I filmed on my iPhone, so apologies for the camera work. Sasha Rush: So we've generated this output. It's just a sequence of tokens. We're gonna send those sequence of tokens to this model that's gonna read it, then it's gonna isolate a specific turn that it says is problematic. Then we're just gonna do text manipulation. We're just gonna take that trajectory and we're literally just gonna smash in some extra tokens. Host: After Cursor injects these hint tokens, they run another forward pass. The trajectory itself doesn't change, but the hint causes the model to assign lower probability to the error tokens. Cursor then trains the original model to match those probabilities, basically teaching it to downweight these specific mistakes. There's a lot more nuance that we couldn't include in this mid-roll. If you want to watch the full thing, I posted it on my Twitter. And if you want to try out Composer 2.5, head to cursor.com/dwarkesh.

Do economists have any advice for countries which are not in the AI production chain? If you're not either producing the AI models, you're not producing the hardware that goes into AI models, if you're not Korea making HBM or Taiwan with the fabs or the Netherlands with ASML. India or Nigeria, what should they be doing right now? If you're talking to Modi right now, what do you say?

Alex Imas: 在我看来,经济学界在研究资源分配上最大的盲点之一就是,对于处于 AI 时代的中等收入发展中国家的关注不够。这也是我自己常常自责的地方。目前研究这个问题的人远远不够。有的情景中,AI 技术会分配、扩散到尼日利亚和各个发展中国家,从而创造了公平的竞争环境,基本在能力方面给了它们一次拉升的机会。但还有另外一个截然不同的世界,在那里因为他们缺乏足够的资源,他们没在训练模型,也没有硬件,于是直接被彻底抛在了后面。而且随着自动化的发展,现在我们在发达国家也能生产那些初级商品了。然后这些发展中国家连消费市场都挤不进去了。那样的一个世界看起来相当糟糕。

Original English

Alex Imas: I think the biggest lack of resources that we have allocated in the economics profession is thinking about middle-income developing countries in the age of AI. This is something I fault myself with as well. There's not enough people thinking about this question. There are scenarios where you get AI technology being allocated and dissipating to Nigeria and developing countries, leveling the playing field, essentially giving them a level up as far as capabilities. But there's another world where, because they don't have enough resources, they're not training the models, they don't have the hardware, and they just completely get left behind. And because of automation, we can produce commodities in developed countries now. Then we don't even have the consumer market. That world looks pretty bad.

Phil Trammell: 这在我看来像是“混乱中间期”案例的延伸。“混乱中间期”仅在一系列很窄的情景下才算是件坏事,它的途径之一不仅在于随着蛋糕做大从而使重新分配变得容易,还在于利率会变得极高,或者换句话说,除了带有“人类固有的价值的商品”外,其他所有物品的价格都将断崖式下跌。这差不多是一枚硬币的两面。一点点的积蓄到了第二年就会转化为大量的消费力。如果事情真的朝着极为不利的方向发展,即我们刚刚跨越资本的生产力足以取代大量工作这一门槛,但其生产力又没强到能让利率走高以及资本生产的商品价格大跌的地步,这确实很糟糕。否则即便是没有重新分配,哪怕是一点点储蓄也将能挽救许多人。

Original English

Phil Trammell: This seems to me like an extension of the messy middle case. One of the ways in which the messy middle might only be bad in a narrow range of scenarios isn't just that it would be easy to redistribute because the pie would be bigger, but because the interest rate would be way higher, and/or, equivalently, the price of everything except human-intrinsic goods would be falling really rapidly. They’re sort of two sides of the same coin. A little bit of savings would turn into a lot of consumption next year. Things have to go really wrong for us to just get over the threshold of capital being productive enough to automate lots of work, but not be productive enough that the interest rate is high and the price of capital-produced goods is falling a lot. Even without redistribution, a little bit of savings will save a lot of people.

主持人: 你的意思是,如果发展中国家在发达国家里留有一点储蓄,这些钱将足以产生大量的盈余,从而让它们能够——

Original English

Host: You're saying if the developing countries have some savings in the developed world, that will be enough to produce a lot of surplus that they can then—

Phil Trammell: 它们到时候就能用这笔储蓄消费许多东西。但是在这种情况下,“混乱的中间期”可能会更长。它们无论是在拥有的资本量上,还是在跟全球经济融合绑定的程度上,起点都要低得多。因此我认为他们现在就参与进来是非常重要的。对于究竟该以投资到正确供应链上的主权财富基金(sovereign wealth funds)形式来实现,还是该直接发放补贴好让他们的公民自己去买点儿份额,我没有很强烈的个人倾向——

Original English

Phil Trammell: They will now be able to consume a lot using their savings. But the messy middle could be wider in this case. They're starting from such a lower level in terms of how much they have and how much it's actually indexed to the global economy. I think it's important for them to get on it now. I don't have strong feelings about whether it should take the form of sovereign wealth funds that invest in the right supply chains or just subsidies to their own citizens to buy a little bit of—

主持人: 这是一个至关重要的关键点。如果我们前面关于那些贪婪优化器面临着自然选择机制的论点站得住脚,那我们早先讨论那些拥有洛克菲勒家族级别财富的人的后代为何没能控制一切的时候。其中一个原因就是,要对整个经济体进行指数化投资简直难如登天。也许那些大佬原本确实想要让子孙们对经济进行指数投资,并让财富跟随经济增长的步伐去增值,如果是那样,他们的继承人现在早就是万亿富翁了。在指数基金(index funds)诞生之前,这确实极其困难。如果你回顾100年前,经济体系中仅有极小的一部分,却在当今创造的价值中占据了绝大多数。倘若你当年不幸错失了投资这些领域的机会,你的财富就会停滞不前。可能存在一段短暂的黄金窗口期,它从指数基金问世算起一直延续到大约五年前,在那段时期你确实能够对整体经济进行指数化投资,使你的财富紧跟经济增长的步伐去同步增值。但如今我们深陷这样一个阶段:回报极度集中,尤其是在非上市公司层面。正像我们在博文中指出的那样,对于普通大众而言,他们接触这种资本的途径被大大削弱了。一般人拥有的资本大部分就是一套普普通通的房子,至少在美国是这样。

Original English

Host: This is actually a crucial point. We were talking earlier about why the Rockefellers of the world, why their descendants don't control everything, if our argument about the selection of these greedy optimizers holds. One argument is just that it's very hard to index the economy. Maybe they would've just decided to have their heirs index the economy and have their wealth grow at the rate of economic growth, and their heirs would be trillionaires by now. Before index funds existed, it was just very hard. A very small fraction of the economy, going back 100 years, accounts for a majority of the value created now. If you missed those particular things, your wealth would've just stagnated. Maybe there was a brief golden window from the creation of index funds up until five years ago where you could actually index the economy and have your wealth grow at the rate the economy grows. But now we're in this world with very concentrated returns, especially to private companies. As we were making the point in our blog post, this is capital that the average person has disproportionately less access to. Most of their capital is having a random house, at least in the US.

Phil Trammell: 或者是房子的一部分产权。

Original English

Phil Trammell: Or a part of a house.

主持人: 正像我们说过的那样,这是一种尤其不适合与 AI 研发、AI 运行或机器人产生互补效应的资本。

Original English

Host: Which, as we were saying, is capital that is uniquely ill-suited to be complementary to the production of AI or the serving of AI or to robots.

Phil Trammell: 或者是富人会抬高其价格的商品种类。

Original English

Phil Trammell: Or the kinds of goods that the rich will bid up the prices of.

主持人: 没错。现在一套房子的价值体现在哪里呢?无非是那块土地离其他人类很近,再加上一些人际关系方面的因素,而这些绝对不会成为未来主要生产要素的东西。

Original English

Host: Exactly. What is the value of a house currently? It's that the land is close to other humans and modulo relational stuff that is just not going to be the main factor of production in the future.

Phil Trammell: 这就是为什么乔治主义税(Georgist tax)根本筹集不到足够维持我们将要讨论的那些项目的资金。

Original English

Phil Trammell: This would be why a Georgist tax would not raise enough money for the sort of programs that we will be discussing.

主持人: 对。但退一步说,我刚才想表达的观点是,如果现在对整个经济体进行指数投资越来越难,而那原本是普通人——在剔除任何形式的全民基本收入(UBI)之后——

Original English

Host: Right. But stepping back, the point I was trying to make is, if it gets harder to index the economy now, and that is the main way in which normal people are supposed to—modulo some sort of universal basic income—

Alex Imas: 在发达国家里。

Original English

Alex Imas: In the developed world.

主持人: ——这本应该是他们借以在 AI 带来的财富中分得一杯羹的方式。这也是发展中国家用来在 AI 的财富增长中占得一席之地的方式。但这目前很难。尼日利亚拥有大量 SK海力士 和 Anthropic 的股票吗?我猜并没有。对于他们来说,仅仅持有标普500指数是远远不够的。

Original English

Host: —are supposed to have some purchase on the wealth from AI. And it's also the way that developing countries are supposed to have some purchase on the wealth gains from AI. But it's very hard. Does Nigeria own a lot of SK Hynix and Anthropic? I'm guessing not. It's not enough for them to just own the S&P 500.

Alex Imas: 这个问题引出了非常关键的一点。未来的 AI 将会像电力网,还是会像社交媒体?以 ConEd 或此地的任何电力供应商为例。这是一家垄断企业,它提供每个人都在使用的资源。但我们认为供电这门生意会导致权力高度集中吗?ConEd 拥有那些压倒性的政治或社会权力之类的吗?不,因为对电力行业而言,其下游创造的大量效益实际上流向了电力使用者,而非实际负责产电的企业。反观社交媒体行业情况正好相反。社交网络覆盖每一个角落。虽然每个人都在使用,但行业利润却几乎被平台吃干抹净了。

Original English

Alex Imas: This brings up a really important point. Is AI going to be like electricity or social media? Think about ConEd, or whatever the electricity provider here is. It's a monopoly. It provides a resource that everybody uses. But do we think about electricity as creating a concentration of power? Does ConEd have this huge amount of political power, social power, or something like that? No, because with electricity, a lot of the downstream benefits actually came to the users of the electricity rather than the actual entity producing it. On the other hand, with social media, it was the opposite case. Social media was everywhere. Everybody uses social media, but the rents went to the platform.

主持人: 这个观点真的很有意思。我个人暂时不一定完全同意这个看法,但我不妨说出我的猜测。越相信未来经济将被 AGI 接管的方式就像如今经济严重依赖电网一样——换句话说,整个经济体系将迎来一场全面且深刻的底层改造——它未来的发展模式就越像电力行业……在未来的标普 500 企业名录里,任何一家公司要是想跻身其中,那绝对是因为它极其充分地利用了 AI。

Original English

Host: That's a really interesting point. I don't endorse this take yet, I'm going to talk out loud. The more you think our economy is going to be run on AGI the way our economy currently runs on electricity—that is, there's a broad fundamental transformation of the entire economy—the more it looks like electricity… Every company in the S&P of the future, if it's going to make it to the S&P 500, it is because it has leveraged AI.

Alex Imas: 完全正确。到那时候你就可以再次做指数化投资了。

Original English

Alex Imas: Exactly. And then you're indexed again.

主持人: 不过回过头来看,如果只看标普500指数过去几十年来所体现的集中度,光是那几个大型科技巨头占比就大得多了……我想这触及了一个最核心的痛点:确实很难去预测,这些私营企业最终究竟能将因 AI 爆发所产生的利润红利控制到何种程度。

Original English

Host: But then again, I guess if you just look at how concentrated the S&P is over time, just these big tech companies much more so… I guess this goes to a fundamental point that it's hard to reason about how much of the gains from AI these individual private companies will be able to control.

Alex Imas: 我认为在这个议题中,“开源模型”将是一个核心焦点。要是我们真的身处开源模型的水平只比最尖端技术晚半年(或者九个月)落地的世界里,那不论我们何时实现 AGI 或者别的什么,只要再过半年,这项资源就会在全世界普及。

Original English

Alex Imas: I think the open model thing is going to be a big point here. If we're indeed in a world where the open models are six months behind the frontier—or nine months—then we'll hit AGI, we'll hit whatever, and in six months, everybody has access to this resource.

主持人: 这再次说明了所有问题之间都有盘根错节的联系。关于是否存在指数级收益增长的问题直接关系到 AI 自我递归改进的可能性。即便不是递归改进本身,也可以是持续学习或者说在线学习(online learning),这种方式能够让模型在实际运转中自主学习。一旦被部署,它就能源源不断地汲取知识。上述所有有关技术的预测直接关联到了另一个问题:像乌干达这样的国家在未来有没有可能分到 AGI 红利的一杯羹。

Original English

Host: This goes to show you that every question is connected to every other. That question about whether there's runaway gains connects to questions about recursive self-improvement. Even if not recursive self-improvement, then continual learning, or online learning, which lets a model learn on the job. So if it's deployed, it gets to learn more. These are just forecasting technical questions which then impact whether Uganda will have any purchase on the returns of AGI.

Alex Imas: 刚才我为什么非要把话题扯到这上面,主要是考虑到在应对“混乱的中间期”以及给发展中国家开药方这件事上,大家经常单纯地给出一个不成熟的建议:就是让劳动者转行再培训。你们得办一些扶持就业的项目,或者让巨头们在你们国家兴建几座数据中心。我觉得你们俩刚才暗示的发展策略更贴近于“干脆直接买爆 AGI 的大盘指数”。这条路走起来肯定比前者轻松得多,成功概率也高多了。实际上这里有两套剧本:一个是行业走向垄断集权,那时候投资 AGI 指数难如登天;而在另一个世界里它就像水电网。几乎所有的企业全在深度利用 AGI。如果是这种情况,那你只需要买指数就好。尼日利亚只要买入指数基金,由于存在开源模型,尼日利亚自然也就掌握了 AGI 的力量。

Original English

Alex Imas: The reason I'm emphasizing the question is I think both for the messy middle and for developing countries, a recommendation that is often made naively is that you've got to do some kind of retraining. You've got to do some kind of jobs program, or you've got to have them build data centers in your country. I think you guys are suggesting something closer to just buying the index of AGI. That's probably a much cleaner strategy and much more likely to succeed. These are the two scenarios. I think there is a world where it is concentrated, in which case it's going to be really hard to index AGI. There is another world where it is electricity. Basically every company has access to AGI. So you just buy the index. Nigeria just needs to buy the index, and Nigeria has access to AGI because of the open models.

Phil Trammell: 回到究竟是“转行培训”还是“买入指数”的问题上来。如果 AI 的浪潮真的席卷全球,我会把指数化投资放在首位考虑。但我绝不会仅以此为依赖。在诸如“混乱中间期”或 AI 到来遥遥无期的较长过渡期内,如果没趁此掌握最新的计算机使用方式,这无异于把巨额价值拱手让人。在我看来,这两者并非完全不能并存。

Original English

Phil Trammell: Just to get back to the question about whether to go with retraining or trying to index. I would prioritize trying to index, just given how fast AI could hit the world. But I definitely wouldn't just rely on that. In the messy middle cases or the long-timeline cases where we don't get anything like AGI all that soon, it would be leaving a lot of value on the table if you could have retrained to be a bit better educated on how to use the latest wave of computing. I don't think there's that much of an either/or there.

主持人: 这件事让人感到悲观的根源可能在于,一个国家贫穷的原因往往是该国的教育体系实在太差,所以指望这个贫穷国家能在培训国民如何使用 AI 方面成为世界翘楚,显然这策略在他们身上希望渺茫。

Original English

Host: Maybe the reason to be pessimistic about this is because one of the reasons a country is poor is that it has a bad education system, so becoming the best in the world at retraining people at using AI doesn't seem like a particularly promising strategy for that poor country.

Alex Imas: 尽管发展中国家身上确实出现过跳跃式发展的现象,比如移动支付的发展就是一个绝佳案例。尼日利亚手机银行的普及程度甚至碾压德国。全民都在用手机转账交易。他们手机上都装有这类软件,这种事对他们来说成了家常便饭。尽管我不敢妄下断言,但面对像 AI 这般具有跨时代颠覆性质的技术,这些国家极有可能彻底越过所有的中间发育阶段,直接迎来爆发性的经济增长。

Original English

Alex Imas: Although there are cases where, in developing countries, you had this leapfrogging effect with, for example, mobile banking. It's much more prevalent in Nigeria than it is in Germany. Everybody is doing mobile banking. They have it on their phones, and they're constantly doing this sort of thing. Again, I'm not putting probabilities on this, but with a transformative technology like AI, you could get leapfrogging where you skip the step in the middle and get really astronomical growth.

Phil Trammell: 谈及指数化投资操作的便利程度问题,它绝对需要我们严阵以待且持续关注。但就如我们在自己文章中所述,并有不少智者也指出的一样:目前做指数化投资门槛其实并不算高。确实,尽管近期投资回报走向私有化的趋势愈加明显,但纵观美国市场,非上市公司在全美那些叫得上名号的非微型企业总市值里的占比还是远远不到20%。人们现在满脑子想的都是 OpenAI 或是 Anthropic。假设那两家成了吸干全球财富的无底黑洞,那诸如开源模型能否紧跟脚步这种问题,将会变得十分要命。但就连这些企业看来也会在不久的将来上市。因为那些一直在阻碍企业走向公开发行阶段的阻力(比如冗繁复杂的各种信息披露要求等),很有可能被 AI 自身大刀阔斧地解决掉。况且,这还能帮助他们去争取到更广泛潜力的投资人。让我来猜的话,即便短期内出现了一些逆流,但长期而言,那些旨在扫清上市障碍以降低人们投资门槛的大趋势是不会改变的。

Original English

Phil Trammell: Just about the ease of indexing, I think it's definitely something to worry about a bit and keep an eye on. But as discussed in our own essay, and as other people have pointed out, it's already not that hard to index. There's been a bit of an increase in the privatization of returns, but still, well under 20% of the total market cap of non-tiny companies in the US is private. Everyone thinks about OpenAI and Anthropic. If that's where all the wealth will accrue, then all these questions about whether open models will stay only a little bit behind, those are important. But even they look like they're going public before too long, probably. The frictions that have been keeping companies from going public might themselves be alleviated by AI a lot, just all of the disclosure requirements and whatnot. They want to get access to more potential investors, too. If I had to guess, I would guess that the long general trend of lowering those frictions and making it easier for more and more people to index will continue, despite the recent bump in the other direction.

主持人: 这反倒让我更加期盼这些实验室们早日能被普遍化、商品化,哪怕退一万步,也希望能看到他们及早挂牌交易。但我最由衷的期望还是它们被完全地商品化。我个人的预感是,要想使 AI 真正在民众间普及,并且最关键的是能带来繁荣在世界范围内的共享,只有在一个条件达成时才可能出现,那就是想把持 AI 赚来的利润的难度,堪比如今想完全垄断电力网带来的利润一样。

Original English

Host: This actually makes me hope even more so than before that the labs do get commoditized, or at the very least they go public as soon as possible. But hopefully they just get totally commoditized. I think AI will be much more popular and, more importantly, will be much more likely to lead to broad increases in prosperity if it is as hard to capture the gains of AI as it is to capture the gains of electrification.

Alex Imas: 分毫不差。毕竟现在这世上可没出个什么所谓的“抵制电网协会”。

Original English

Alex Imas: Exactly. There's no anti-electricity people out there.

主持人: 我的意思是电力这玩意不会端了你的饭碗,但是——

Original English

Host: I mean electricity doesn't take your job, but—

Alex Imas: 实际上,当年这玩意也是砸过一些人饭碗的。

Original English

Alex Imas: Well, it takes some people's jobs.

主持人: 确实是砸了点儿饭碗,有道理。

Original English

Host: It took some people's jobs, yeah.

Alex Imas: 这话扯得稍微有点偏了,但是我想说在某种意义上叙事就是一切。如今市面上充斥着针对 AI 极为悲观绝望的调子,完全是因为还没人跑出来讲好一个振奋人心的故事的缘故。这也是有客观原因的。毕竟让人们去脑补一个虚无缥缈的好事,远比让他们去设想一个手头既得利益将要受损的情况难多了。上播客随便抛出一句:“大伙注意了啊,你们心心念念的那些饭碗通通不保啦”,远比凭空捏造一个还没影子的极乐盛世要容易得多了。

Original English

Alex Imas: This is maybe tangential to the conversation but I think narratives matter. There's this really negative narrative around AI right now, but that's because people are not putting out the positive narrative. There’s a reason. It's more difficult to imagine a good thing that doesn't exist than losing something that exists. It's much easier for somebody to go on a podcast and say, "These jobs that you like, they're going away," than for somebody to spin up a utopia which doesn't exist yet.

Phil Trammell: 我希望接下来的话不至于太突兀,但我若不趁机指出前沿 AI 被普遍化这事所引发的技术竞赛态势这一个沉重代价的话,那就是我的失职了。基于安全方面的权衡考量,我们反而会更希望处于绝对前沿阶梯的公司少一些。这样做才可能在各个尖端玩家之间创造出必要的余量(buffer),使得当他们为了降低失控风险而试图猛踩刹车时能成为可能。这点之所以与我们此前讨论“红利该被如何广泛触达分配”这个点密切挂钩的原因在于,两者间可能压根就没有外界臆想中存在的所谓尖锐矛盾。总有声音说,前沿 AI 的彻底商品化确实能惠及全民——尽管极度内卷的自由市场必将隐含有很大风险;或者另一种剧本是由于头部大哥和小弟们实力断档严重所以一切风平浪静。但难道说因为领先者掌握绝对控制权就会导致财富全被他一家卷跑吗?绝非如此。你可以拥有一道明显的护城河,只要维持这家公司的所有权面向社会广泛散出,使其依然是一家对全体公众开放股份的普通公司就行了。

Original English

Phil Trammell: I hope this isn't too out of left field, but I would be remiss if I didn't point out one big cost of having commoditized frontier AI models, which is the tech race dynamic. For safety purposes, you might want fewer frontier companies so that each one has a buffer in case they want to slow things down to make things safer. The way this relates to our point before about the widespread access of the returns, is that I think there's a lot less of a trade-off there than some people imagine. Some people think either frontier AI gets commoditized and we all enjoy the benefits—but there might be some risk, because the market's really competitive and cutthroat—or things are safer because there's a big gap between the leader and the laggard. But that means the leaders get fantastically wealthy? No. You could just have a relatively big gap, but it's a public company, and ownership in it is widely distributed.

主持人: 就我自己近期的情况来看,我反而开始相信那项叫做技术商品扩散的隐患——它会让滥用 AI 的门槛被大幅踩低——对比它带来的海量收益而言是绝对值得忍受的。我不禁担忧那些力量过度集中的极少数实验室不仅掐断了把这些财富反哺反哺给芸芸众生的管道,并且会给政府亲自下场树立一个最为显眼、明确无误的政治活靶子。比如在《国防生产法案》(Defense Production Act)出台期间发生于 Anthropic 身上的威压恐吓事件就是最好的例证。如果说本来压根没有那么几间一骑绝尘将同行远远甩在身后的垄断实验室的影子的话,这种居高临下的威胁压根就找不到地方使劲。不管怎么说,多谢两位的参与。我深感虽然遗留下了海量的迷局还没破解掉,但是理清楚所有的核心矛盾与重要分歧的第一根枝干长啥样还是极为受用的。

Host: More recently, I have been thinking that the risk of commodification—which is that it diffuses the ability to use AI to harmful ends—is worth the benefit. I worry that having these concentrated labs not only makes it so that the surplus isn't as widely distributed through society, but also creates a very tangible, clear political target for the government. We saw this with the Defense Production Act threat against Anthropic. If there wasn't one lab, or a couple of labs, that are clearly ahead of others, this kind of threat would be much harder to make. Thank you guys for doing this. I feel like there's a lot of unresolved questions, but it is helpful to know what the first branch is along all these important dimensions.

Alex Imas: 太棒了。
