科技泡沫的语言陷阱
人工智能(AI)泡沫已经开始泄气,并且有一些迹象表明,其中最强大的迹象有时并非来自股市。
View/Hide Original English
AI bubble is already deflating and there are signs and sometimes the most powerful one is not in the stock market.
它体现在“全自动驾驶(Full Self-Driving)”和“监督式全自动驾驶(Full Self-Driving Supervised)”这些词语中。
View/Hide Original English
It's in the words full self-driving full self-driving supervised.
你能分辨出其中的区别吗?它们几乎是相同的短语,但产品却完全不同。
View/Hide Original English
Can you tell the difference? It's almost the same phrase but entirely different products.
这一个词就足以告诉你科技泡沫是如何诞生的,以及我们为什么总是相信它们。
View/Hide Original English
That single word tells you everything you need to know about how tech bubbles are born and why we always believe them.
问题是,如果这些迹象一直都在,我们为什么还会上当?投资者又是如何上当的?
View/Hide Original English
And the question is, if the signs were always there, why did we fall for it? How did investors fall for it?
答案根本与技术无关,而是因为人类就是如此。
View/Hide Original English
And the answer isn't about tech at all. It's because that's what people do.
现在关于AI泡沫的讨论非常多,无论你是否相信它会破裂。
View/Hide Original English
There is so much noise about AI bubble right now, whether you believe it or not, whether it'll burst.
但一直困扰我的问题是:为什么?
View/Hide Original English
But the question that kept bothering me is why?
它们为什么会形成?我们经历过互联网泡沫,经历过2008年金融危机。
View/Hide Original English
Why do they form? We've seen the dot. We've seen 2008.
我们为什么会重复同样的错误?今天不是要预测或猜测它何时或是否会破裂。
View/Hide Original English
Why are we repeating the same mistakes? Today isn't about predicting or speculating when or whether it'll burst.
而是要理解科技泡沫最初是如何形成的。
View/Hide Original English
It's about understanding why tech bubbles are born in the first place.
让我们深入探讨。
View/Hide Original English
Let's dive in.
你可能已经注意到,行业是如何从“自主代理(Autonomous Agents)”和“元宇宙(Metaverse)”转向“副驾驶(Co-pilots)”、“虚拟助手(Virtual Assistants)”和“AI伴侣(AI Companion)”的。
View/Hide Original English
You might have noticed how the industry began shifting from autonomous agents, metaverse to co-pilots, virtual assistants, AI companion.
最近,AI的语言学确实发生了转变。
View/Hide Original English
The linguistics of AI have really shifted lately.
但请记住,仅仅两年前,Meta公司还积极推动将元宇宙作为其旗舰方向的叙事。
View/Hide Original English
But remember how just two years ago, Meta has aggressively pushed the narrative of metaverse as its flagship direction.
还记得马克·扎克伯格(Mark Zuckerberg)戴着眼镜的视频吗?
View/Hide Original English
And remember the videos with Mark Zuckerberg wearing the glasses?
那些视频无处不在。
View/Hide Original English
Those videos were everywhere.
著名的Facebook更名为Meta,他们向Reality Labs(Meta的VR/AR部门)、虚拟现实头显(VR sets)、虚拟形象(avatars)和虚拟生态系统(virtual ecosystems)投入了数十亿美元。
View/Hide Original English
The famous Facebook became Meta and they invested billions into reality labs, VR sets, avatars, virtual ecosystems.
这是该公司成立以来,Facebook首次进行全面品牌重塑,而这一切都因为AI而发生。
View/Hide Original English
This was the first time since the company's inception when Facebook did a fullscale rebranding and all of it happened because of AI.
但快进到今天,整个Meta的叙事正在慢慢成为过去。
View/Hide Original English
But fast forward to today and the whole meta narrative is slowly becoming a thing of the past.
当前的潮流是“个人超级智能(Personal Super Intelligence)”。
View/Hide Original English
The current vibe is personal super intelligence.
你可以感受到“代理式AI(Agentic AI)”主题的影响。
View/Hide Original English
You can smell the effect of Agentic AI theme.
有趣的是,他们仍在投资和生产硬件。
View/Hide Original English
The interesting thing is that they still invest and produce hardware.
你一定见过他们最近推出的AI眼镜。
View/Hide Original English
You must have seen the AI enabled glasses that they launched recently.
眼镜和许多AI硬件现在是他们的主打产品,但元宇宙的语言正在慢慢被扫到一边,因为超级智能接管了整个品牌。
View/Hide Original English
The glasses and a lot of AI hardware is their thing now, but the metaverse language is being slowly swept under the rug because super intelligence took over the entire branding.
这种语言上的品牌重塑,如果我可以说的话,也可以在其他行业中发现。
View/Hide Original English
And this linguistic rebranding, if I may, can be spotted in other industries as well.
例如,自动驾驶出租车(robo taxi)市场,特别是美国汽车工业巨头通用汽车(General Motors)。
View/Hide Original English
For example, robo taxi market and especially the giant of the American automotive industry, General Motors.
在通用汽车内部,他们有一个名为Cruise的部门。
View/Hide Original English
And within the GM, they have a division called Cruz.
Cruise的主要重点是自动驾驶汽车和自动驾驶出租车服务。
View/Hide Original English
Cruz's primary focus is autonomous vehicles and robo taxi services.
三年前,最初的定位是自动驾驶出租车。
View/Hide Original English
Three years ago, the original positioning was autonomous robo taxis.
他们的承诺和叙事是在旧金山和其他主要城市实现完全无人驾驶的四级自动驾驶(Level Four)汽车。
View/Hide Original English
The promise and the narrative was fully driverless level four cars in San Francisco and other major cities.
Cruise的公关、投资者演示文稿和新闻稿都将其描述为广泛可用的无人值守按需自动驾驶出租车服务的突破。
View/Hide Original English
Cruis's PR investor decks press releases all described as a breakthrough in widely available uncwred ondemand robo taxi service.
但后来在两年前的2023年10月,Cruise部门因多起事故而陷入困境。
View/Hide Original English
But then two years ago in October 2023, the cruise division got in trouble because of the multiple incidents.
甚至发生了一起出租车在碰撞后拖拽行人的事件。
View/Hide Original English
There was even one when a taxi was dragging a pedestrian after a collision.
正如你所想象的,这随后引发了巨大的反弹。
View/Hide Original English
And as you would imagine, this was followed by a major backlash.
Cruise的许可证被暂停,公众对安全感到担忧,整个叙事立即转向“运营暂停、调查进行中、根本原因分析”。
View/Hide Original English
Cruz's permits got suspended, public safety concerns, and the whole narrative immediately shifted to operation suspended, investigation ongoing, and root cause analysis.
你可能会问,但Waymo(Alphabet旗下的自动驾驶技术公司)是如何做到的?
View/Hide Original English
You may ask, but how did Whimo pull it off?
Cruise和Waymo都曾争夺自动驾驶出租车业务的主导地位,但在品牌、公关以及最重要的是运营决策方面存在巨大鸿沟。
View/Hide Original English
Then Cruz and Whimo both fought for dominance in autonomous driverless taxi business, but there was a chasm in branding, PR, and most importantly, operational decisions.
Cruise积极地将自己宣传为完全无人驾驶的四级自动驾驶出租车的先驱。
View/Hide Original English
Cruz aggressively marketed as a pioneer of fully driverless. Level four, autonomous robo taxi.
自动驾驶分级与市场策略
以防你不熟悉这个分级系统。
View/Hide Original English
Just in case you're unfamiliar with this whole leveling thing.
零级自动化(Level Zero)意味着没有自动化,你驾驶汽车,你负责一切。
View/Hide Original English
Level zero is no automation. You drive the car. You drive everything. You're responsible for everything.
一级自动化(Level One)是驾驶辅助,汽车可以自动完成一件事,比如巡航控制(Cruise control)、车道保持或制动,但你仍然控制其他一切。
View/Hide Original English
Level one is driver assistance. The car can do one thing automatically. Cruise control, lane keeping, or braking, but you still control everything else.
现在,二级自动化(Level Two)是部分自动化,汽车可以做两件事:转向和制动,或者转向和加速。
View/Hide Original English
Now, level two, partial automation. The car can do two things. Steer and brake or steer and accelerate.
因此,它可以在理想条件下在高速公路上自动驾驶,但你必须保持警惕,并能够随时接管。
View/Hide Original English
So, it can drive itself on a highway in ideal conditions, but you must stay alert and be able to take over at any point.
你负责监督,你是责任人。
View/Hide Original English
You are supervising and you're the one responsible.
三级自动化(Level Three)是有条件自动化,汽车可以在特定条件(如高速公路)下处理大多数驾驶任务,但如果出现问题或条件变化,它可能会要求你接管。
View/Hide Original English
Level three, conditional automation. When the car can handle most driving tasks in specific conditions like highways, but it can demand you take control if something goes wrong or conditions change.
在这种情况下,你负有部分责任,并处于待命状态。
View/Hide Original English
In this case, you're partially responsible and you're on standby.
四级自动化(Level Four)是高度自动化,这就是Cruise所承诺的,也是Waymo最终能够实现的。
View/Hide Original English
Level four, high automation. This is what Cruz promised and what Whimo was able to achieve in the end.
汽车可以在没有人为干预的情况下自动驾驶。
View/Hide Original English
The car can drive itself without human input.
正常操作不需要人类驾驶员,但系统有局限性。
View/Hide Original English
A human driver is not needed for normal operation, but the system has limits.
例如,只能在好天气或特定道路上。
View/Hide Original English
For example, only in good weather or only on certain roads.
四级自动化意味着你可以在车里睡觉,不用注意。
View/Hide Original English
Level four means that you can sleep in your car and not pay attention.
最后,五级自动化(Level Five)是完全自动化。
View/Hide Original English
And finally, level five, full automation.
汽车可以在任何地方、任何条件下自动驾驶。
View/Hide Original English
The car can drive itself anywhere in all conditions.
永远不需要人类,这是完全无人驾驶,目前尚不存在。
View/Hide Original English
No human needed ever. This is complete driverless and this does not exist yet.
因此,对于Cruise来说,叙事重点在于快速商业化推广。
View/Hide Original English
So for cruise, the narrative was focused on rapid commercial rollout.
他们大胆宣称完全移除人类驾驶员,然后扩展到更广泛的地理区域。
View/Hide Original English
A lot of bold claims about removing a human driver entirely and then scaling up to wider geography.
其商业模式旨在实现纯移动运营,所有操作都通过叫车应用程序完成,他们的整个商业模式和市场进入策略都是一次性颠覆。
View/Hide Original English
The business model aimed for mobile only operations all done through a ride app and their whole business model and go to market strategy was all at once disruption.
没有公开讨论分阶段推出。
View/Hide Original English
There were no public talks about a phase roll out.
另一方面,Waymo是Google的产品。
View/Hide Original English
Whimo on the other hand is Google's product.
Waymo是一家技术原生公司的产物。
View/Hide Original English
Whimo was clearly a lot more prepared knowing how tech launches work.
Waymo显然准备得更充分,了解技术发布的工作方式。
View/Hide Original English
They market it as the world's first commercial also level four self-driving service but with a measured safety first pilot in Phoenix, Arizona.
他们将其宣传为世界上第一个商业化的四级自动驾驶服务,但在亚利桑那州凤凰城进行了有计划的、安全至上的试点。
View/Hide Original English
They put a big emphasis on the user experience and the messaging kept reassuring about ongoing safety oversight.
他们非常重视用户体验,并且信息传递不断强调持续的安全监督。
View/Hide Original English
They went with a phased roll out and framed autonomy as incremental innovation, not fast disruption.
他们采取了分阶段推出,并将自动驾驶定义为渐进式创新,而非快速颠覆。
View/Hide Original English
And unlike GM, Whimo stayed afloat with its autonomous claims and their clearly communicating limitations and suspensions.
与通用汽车不同,Waymo凭借其自动驾驶主张以及清晰地沟通限制和暂停而得以维持。

But when I need to compile my findings and present, whether it's on video or if I'm presenting a product release at work, making all of that data readable, digestible, and aesthetically pleasing, is a torture for me.
但是,当需要整理我的发现并进行演示时,无论是通过视频还是在工作中发布产品,将所有数据变得可读、易懂且美观,对我来说都是一种折磨。
View/Hide Original English
I am really not creative when it comes to visuals.
在视觉方面,我真的缺乏创造力。
View/Hide Original English
And as someone who works in product, I don't get to just opt out of presentations.
作为一个从事产品工作的人,我不能仅仅选择不做演示。
View/Hide Original English
I have to do companywide updates. I have to do team presentations. I have to do feature releases and customer webinars.
我必须进行全公司范围的更新,团队演示,功能发布和客户网络研讨会。

And I need slides that don't just contain bullets. They need to land.
我需要的幻灯片不仅仅是项目符号,它们需要有说服力。
View/Hide Original English
And if I'm presenting to five different audiences, they need to land five different times in five different ways.
如果我向五个不同的受众演示,它们需要以五种不同的方式在五个不同的场合产生效果。
View/Hide Original English
That is why a tool like **Gamma AI** is a lifesaver for me.
这就是为什么像Gamma AI这样的工具对我是救星。

特斯拉FSD的误导性营销与法律后果
特斯拉(Tesla)将“全自动驾驶(Full Self-Driving)”更名为“监督式全自动驾驶(Full Self-Driving Supervised)”,如果你仔细思考,自主驾驶和监督式自主驾驶之间存在天壤之别。
View/Hide Original English
Tesla's rebranding from full self-driving to full self-driving supervised, which if you really think about it, there is a world of a difference between autonomous and supervised autonomous.
它们听起来相似,但用户体验完全不同,因为监督式自主驾驶本质上承认该产品是二级驾驶辅助(Level Two Driver Assistance),而不是五级或四级自动驾驶(Level Five or Level Four Autonomy)。
View/Hide Original English
They sound similar, but they're completely different user experiences because supervised autonomous essentially admits that the product is level two driver assistance, not level five or level four autonomy.
因为四级或五级意味着你可以在驾驶座上睡着,更不用说在后座了。
View/Hide Original English
Because level four or level five implies that you can fall asleep in a driver's seat, let alone in the back seat.
特斯拉的这种虚假广告在美国、中国和澳大利亚引发了多起关于欺骗性营销的诉讼。
View/Hide Original English
This false advertising on Tesla's part triggered a number of lawsuits in the US, China, and Australia over deceptive marketing.
这种营销的问题在于,当你提到“全自动驾驶”时,你暗示的是四级或五级自动驾驶,这意味着车辆在任何条件下都不需要人工输入或监控。
View/Hide Original English
The problem with this marketing is that when you say full self-driving, you imply level four or level five autonomy, meaning that the vehicle requires no human input, no monitoring under any conditions.
媒体和营销喜欢“无人驾驶”这个词。
View/Hide Original English
The media and marketing loves the word driverless.
作为一个普通消费者,当你听到“无人驾驶”时,你会听到什么?
View/Hide Original English
And what do you hear as an average consumer when you hear driverless?
你听到的是汽车可以自己驾驶。
View/Hide Original English
You hear the car can drive itself.
但“监督式全自动驾驶”在现实中意味着系统完全需要持续的人工监督,驾驶员随时准备接管。
View/Hide Original English
But full self-driving supervised in reality implies that the system fully requires constant human supervision with the driver ready to take control at any point.
这是二级自动驾驶(Level Two Autonomy),二级在功能上等同于巡航控制。
View/Hide Original English
This is level two autonomy and level two is functionally equivalent to cruise control.
这种差异不是语义上的,而是类别上的。
View/Hide Original English
The difference is not semantic, it's categorical.
二级意味着你始终负责。
View/Hide Original English
Level two means you're always responsible.
四级或五级意味着你可以在座位上睡觉。

Level four or five means you can sleep in your seat.
这不仅仅是缩减,而是一种根本不同的产品。

The driver took his eyes off the road and neither the driver nor Tesla reacted to what was happening in the intersection and the car drove straight through it.
现在听听判决的细分。这很重要。
View/Hide Original English
Now listen to the verdict breakdown. This is important.
责任是这样划分的:驾驶员承担67%的责任,特斯拉承担33%的责任。
View/Hide Original English
The liability was split like this. 6 to 7% of fault assigned to the driver, 33% assigned to Tesla.
这33%归咎于特斯拉意味着系统本身被认为是造成伤害的重要原因,而不仅仅是被驾驶员误用的被动工具。
View/Hide Original English
That 33% assigned to Tesla means that the system itself was found to be a meaningful cause of harm, not just a passive tool that was misused by a driver.
这给整个汽车行业发出了一个信号。
View/Hide Original English
And this was the signal to the entire automotive industry.
现在他们必须谨慎对待自己的营销。

And now they have to be careful with their marketing.
如果你正在听这段内容并思考,好吧,Meta对整个元宇宙很兴奋,但现在他们正在逐渐远离。

So, I spent the last week studying why bubbles form, why we don't learn, and why even though we know that the bubble is coming, we keep buying AI stocks.
答案是:这是人类本性。

And the answer to that is that it's human nature.
这个泡沫的形成是技术不准确、经济压力和大量心理偏差的完美结合。

And the reason this bubble has formed is a perfect storm of technical inaccuracies, economic pressures, and a mountain of psychological biases.
让我向你证明。
View/Hide Original English
Let me prove it to you.
科技泡沫的技术局限性:缩放定律的失效
直到最近,整个AI的进步都依赖于“缩放定律(Scaling Laws)”的概念。
View/Hide Original English
The entire AI progress until recently has relied on the notion of scaling laws.
缩放定律本质上是假设增加计算能力(Computing Power)(我指的是计算机处理数据的速度和量,即输入AI的文本、图像和其他信息的数量)和模型规模(Model Size)(即AI拥有的参数(Parameters)数量,可以将其视为机器上可调节的旋钮数量)可以提高性能的可预测性。
View/Hide Original English
Scaling laws are essentially principles that assume that increasing computing power and by computing power I'm referring to how fast and how much a computer can process data meaning the amount of text images and other information that are fed into AI and model size which is how many parameters AI has think of it as like the number of knobs that you can have in a machine. So scaling laws assume that increasing all three improves performance predictability.
其基本思想是越多越好。
View/Hide Original English
The underlying idea is the more the better.
数据越多越好,模型越大越好,计算能力越强越好。
View/Hide Original English
The more data the better. The bigger the model the better. The more computing power the better.
你可能会问是谁提出了这个理论。这种因果关系从何而来,它甚至存在吗?
View/Hide Original English
You may ask who came up with that. Where does this causal relationship come from and does it even exist?
答案有些令人惊讶,因为没有人真正提出过。
View/Hide Original English
And the answer is somewhat surprising because nobody really did.
30年来,研究人员和数学家只是不断观察到缩放是有效的。
View/Hide Original English
For 30 years researchers and mathematicians just kept observing that scaling worked.
更大的模型意味着更大的结果,更多的数据意味着更少的错误。
View/Hide Original English
Bigger models meant bigger results. More data meant fewer mistakes.
这纯粹是经验性的模式识别,而不是物理定律。
View/Hide Original English
It was pure empirical pattern recognition, not a law of physics.
所以他们一直这样做,但没有人真正深入研究它为什么有效,以及当你用尽可缩放的东西时会发生什么。
View/Hide Original English
So they kept doing it, but nobody was really digging into why it worked and what happens when you run out of things to scale.
而他们确实用尽了可缩放的东西。
View/Hide Original English
And they did run out of things to scale.
他们用尽了高质量的数据,因为互联网上几乎所有高质量、多样化的人类文本都已被收集并用于训练大型AI模型。
View/Hide Original English
They ran out of high-quality data because nearly all highquality diverse human text on the internet has already been collected and used to train large AI models.
他们开始达到计算硬件的物理极限。

Essentially the observation that chip power doubles every couple of years.
这条定律正在急剧放缓,因为这些芯片正在接近原子大小的极限。
View/Hide Original English
And that law is slowing down dramatically because those chips simply approach the limit of atomic size.
他们现在正触及天花板。
View/Hide Original English
And they're now hitting the ceiling.
缩放定律多年来一直有效,但现在每1%的改进都需要10倍甚至100倍的资源,这使得额外的收益变得极其昂贵。
View/Hide Original English
Scaling laws worked for years, but now each 1% improvement requires 10 or even 100 times more resources, which makes additional gains outrageously expensive.
但有一个更深层次的问题,使得数学假设的不准确性在某种程度上变得无关紧要。
View/Hide Original English
But there is a deeper problem that makes the inaccuracy of mathematical assumptions somewhat irrelevant.
那就是数据本身,数据的质量和稀缺性。
View/Hide Original English
And it's the data itself, the data quality and the data scarcity.
互联网包含大约500万亿个文本词元(Tokens)数据。

When you hear 95% AI project failure, the root cause is almost always poor data.
许多大语言模型(LLMs)所基于的基础——缩放定律的概念——正在面临收益递减。
View/Hide Original English
The foundation that a lot of LLMs are based on, the notion of scaling laws, has diminishing returns.
要获得第一个单位的改进需要一个单位的数据,但下一个单位需要10个,然后是100个。
View/Hide Original English
To get to the first unit of improvement requires one unit of data, but the next one requires 10 and then 100.
但每个人都期待着一场革命。

But everybody expecting revolution.
然而这场革命并没有发生,因为它在技术上不可能发生。
View/Hide Original English
But the revolution isn't happening because it cannot happen technically.
这是技术层面。现在让我们转向心理层面。

So this was the technical layer. And now let's move on to the psychological layer.
科技泡沫的心理驱动:线性外推与错失恐惧症
人类容易受到一系列偏差的影响。
View/Hide Original English
Humans are prone to a series of biases.
但当谈到泡沫时,这正是我们线性思维遇到指数增长(Exponents)世界的时刻。
View/Hide Original English
But when it comes to bubbles, this is exactly the moment when our linear minds meet the world of exponents.
这种偏差是双向的。
View/Hide Original English
And this bias cuts both ways.
投资者低估了AI进步的速度。

Investors underestimated how fast AI could progress.
例如,他们错过了英伟达(Nvidia)数据中心收入从6亿美元到410亿美元的指数级增长。
View/Hide Original English
For example, they missed Nvidia's exponential data center revenue growth from 600 million to $41 billion.
他们将Transformer模型(Transformer Models)视为渐进式改进,而实际上它们是跳跃式突破,结果导致那些迟入市场的人产生了巨大的错失恐惧症(FOMO),并急于追赶。
View/Hide Original English
They dismissed transformer models as incremental improvements when they were discontinuous leaps and as a result massive FOMO among those who enter the market late and rush to catch up.
反过来,当公众高估我们离通用人工智能(AGI)这个神奇实体有多近时,是因为他们将最近发生的快速进展线性外推,完全忽略了大语言模型(LLMs)在技术上已达到性能巅峰的事实。
View/Hide Original English
And the opposite way when the public overestimates how close we are to this magic entity of AGI because they extrapolate rapid progress that happened very recently linearly and completely ignore the fact that LLMs have technically reached their peak performance.

AI researchers fully admit it.
