AI 不一定带来“无工作反乌托邦”,也可能是人口下行时代的救命稻草

Marc Andreessen 的核心判断是:把 AI 等同于“大规模失业”过于简化——在过去 50 年技术变革异常缓慢、人口增速下行/移民放缓的背景下,AI 更可能把生产率与岗位更替拉回历史常态,甚至在极端高生产率情景下通过价格崩塌提升全民实际财富,使“无工作反乌托邦”反而不太像主路径。

核心观点

  • “岗位替代=失业”是过于简化的模型:作者引用 Andreessen 的说法,认为过去几十年技术进步慢导致岗位更替少;即使 AI 把生产率增速提高到数倍,也可能只是回到 1870-1930 那种高变革但机会充沛的区间。
  • 人口下降让劳动更稀缺:全球人口增速下降、部分国家走向人口收缩;若再叠加移民放缓,剩余人类劳动力会更“值钱”,从而缓和失业恐慌叙事。
  • AI 的“时机”可能是奇迹般对上了:没有 AI 的人口下行时代更像“经济慢性萎缩”;AI/机器人反而能抵消人口不足,避免经济自我收缩。
  • 极端高生产率的推演:若出现 10%~50%/年的生产率增长(远超历史),会带来产出过剩→价格崩塌→通缩→实际购买力大幅上升,相当于“全民加薪”;社会保障网也因价格下降而更可负担。
  • 总体结论偏渐进式乐观:无论是渐进还是更颠覆的变化,作者强调从基本经济学外推看都更像“好消息”。

跟我们的关联

  • “技术进步速度→岗位更替→机会结构”的历史类比(工业化时代)。
  • 人口结构(少子化/老龄化)与经济增长的关系。
  • AI 作为“补足劳动力供给”的资本替代(机器人/自动化)。

讨论引子

  • 你更担心 AI 带来的“净就业减少”,还是“分配与转型摩擦”(某些群体/地区短期被冲击)?为什么?

在一支反乌托邦未来主义者的舰队之中,他们把线性的思考投射到一个“AI 至上”的未来;而马克·安德里森却像一座潜在乌托邦之光的灯塔,看到的未来截然不同——对年轻人和老年人都同样积极。

在短短几分钟里,这位 Netscape 联合创始人、风投公司 Andreessen Horowitz(a16z)的联合创始人反而认为,我们正经历着历史上一个独特(且最令人惊叹)的时期:AI 的崛起恰好发生在人类文明最需要它的时候……

"我们将恰在真正需要它们的时候拥有 AI 和机器人[在人口萎缩之际],从而让经济不至于真的萎缩。"

简单来说,安德里森认为,对 AI 驱动的大规模失业的担忧过于简单化。

在经历了数十年异常缓慢的技术变革与低水平的岗位更替之后,AI 可能把生产率拉回历史常态(1870—1930 年便是例证),带来机会、创新以及净就业增长,而不是把人挤出岗位。

人口下降与移民减少将让人类劳动越来越值钱。安德里森感叹,AI 出现的时机“堪称奇迹”,它能避免因人口减少导致的经济收缩。

即便在更激进的情景中,生产率的爆炸式提升也会导致产出过剩、价格崩塌,以及巨大的实际财富增长——等同于给每个人“巨大加薪”——同时也让社会安全网更负担得起。

无论是渐进式变化还是颠覆性转变,在安德里森看来,其结果从根本上都是利好的经济消息。

"……年轻人非常担心将来没有他们的工作岗位了。AI 正在取代他们……"

安德里森回应道(重点为我们所加):

所以,把问题归结为“岗位替代/失业”是非常简化的。我觉得这是一种过于简单的模型。而且这又回到了我一开始说的:过去 50 年里,我们的经济实际上处在一个技术变革非常缓慢的阶段……大概只有此前那个时代的一半速度、也只有大约 100 年前的三分之一。

因此,我们正走出这样一个阶段:经济中几乎没有技术进步。与任何历史时期相比,由此带来的岗位更替都少得惊人。所以,即便 AI 把经济中的生产率增速提高到三倍——这当然会是件大事——也只是把我们带回到 1870—1930 年之间那种岗位更替的水平。

而如果你回去读一读 1870 到 1930 年的记述,人们只是觉得世界到处都是机会,对吧?在那样的技术变革速度下,年轻人能够在经济的新领域开辟新的职业,创造新的产品与服务。我们今天现代世界中的很大一部分东西,基本都是在那个时期被发明出来并迅速普及的。

所以,即便 AI 把经济变化的速度提高三倍,也会转化为更高的经济增速;也会转化为更高的就业增长率。确实会发生一定程度的任务层面和岗位层面的替代,但它会被经济增长与创新带来的宏观效应所淹没;相应地,说实话,我认为各个地方都会出现招聘的“井喷”。

再回到一个事实:这一切发生在全球人口增速下降、甚至越来越多地转向人口收缩的背景下。所以,在接下来你知道的 10 年、20 年、30 年里,许许多多国家的人类劳动者将越来越稀缺、越来越“值钱”,字面意义上就是因为人口规模在缩小。

[虽然] 我们并不太想特别谈政治,但看起来全球总体上会在过去 50 年的移民速度上掉头。似乎这是一种广泛发生的趋势——民族主义抬头、对移民速度的担忧——而在像美国这样的国家,历史上的移民规模也一直会随着国民情绪的变化而起起落落。

因此,在像美国(或欧洲任何国家)这样的地方,如果把人口下降与移民减少叠加起来,剩下的人类劳动者会更“值钱”,而不是更便宜。所以我认为,更快的生产率增长、更快的经济增长,再加上更慢的人口增长和更少的移民——这套组合实际上意味着那种反乌托邦式的“没有工作”情形会少得多。我觉得那种担忧很可能完全偏了方向。

"这太有意思了。也就是说,我听到的是你并不是特别担心失业。关键在于时机恰好对上了——人口下降之类的因素,你知道,要让 AI 不造成这种大规模失业,似乎得这些条件都凑在一起?"

安德里森回应道(重点为我们所加):

对。

你看,如果没有 AI,我们现在就会为经济将会怎样而恐慌,对吧?因为我们将面对的是一个人口减少的未来,而在人口减少却没有新技术的情况下,就意味着经济会萎缩,对吧?

这意味着经济会随着时间自己慢慢缩小,机会减少,没有新工作、没有新领域;也没有新的消费需求来源,让人们在各种东西上花钱。因此,你会非常担心进入一个严重下滑或停滞的时期。

本质上,你看到的会是那种极其反乌托邦的情景:经济在时间里“自我安乐死”。

所以,你真正该担心的,恰恰是与大家以为自己在担心的东西相反的方向。我们之所以不那么担心,是因为我们现在知道:我们拥有可以替代人口增长不足、也可以替代未来可能出现的移民不足的技术。

因此,我会说时机在某种意义上奇迹般地对上了:我们将恰在真正需要它们的时候拥有 AI 和机器人,让经济不至于真的萎缩。

这从根本上就是一个好消息。

要走到人们担心的那种“大规模失业”,你得看到远远、远远、远远更高的生产率增速。你得看到那种每年 10%、20%、30%、50% 的生产率增长——大概这种量级——这比地球历史上任何经济体曾经达到过的水平高出好几个数量级。

也不是不可能出现这种情况。我的意思是,你看,我和所有人一样,也会被乌托邦的想象所诱惑。

如果 AI 一夜之间彻底改变一切,那么也许……我们来推演一下那种乌托邦式的情景。

你会得到高得多的生产率增速。

你会得到高得多的技术变革速度。

相应地,你会迎来一场巨大的经济繁荣。

经济会大幅增长,而随之而来的,是价格的崩塌。

于是,那些受到 AI 影响(或被 AI 商品化)的商品与服务的价格会崩塌。

会出现通货紧缩;而通缩的结果是,人们今天购买的一切都会便宜得多,这等同于全社会范围内财富的巨大增加。

这其实值得讲一讲,因为我觉得人们在这个问题上常常会走偏。

所以,如果 AI 真会像乌托邦派或反乌托邦派(不管哪一派)所认为的那样深刻地改造经济,那么接下来必然发生的经济学推导,就是生产率大幅提升。

生产率的大幅提升,从机制上说,就意味着用更少的投入获得更多的产出,对吧?

也就是用更少的投入得到更多的经济产出,对吧?于是你用 AI 来替代人类劳动者。

结果就是,在投入成本大幅降低的同时,产出出现巨大的扩张。

这样一来,在所有受影响的部门,你会看到大量商品与服务涌现。过剩的结果就是价格崩塌,对吧?

价格崩塌意味着:今天要花你 100 美元的东西,明天变成 10 美元,再后来变成 1 美元。

这就等同于给每个人来一次巨额加薪,对吧?

因为他们现在拥有了额外的购买力。

而这份额外购买力又会转化为经济增长,对吧?

新领域随之发展起来。每个人的物质生活都会很快明显改善。而且顺带一提,如果在这一切之后确实出现一定失业,那么提供那种社会保障网、防止人们陷入困苦,也会变得便宜得多,对吧?

因为福利项目需要支付的那些商品与服务的价格都在崩塌,对吧?于是医疗价格崩塌、住房价格崩塌、教育价格崩塌,其他一切的价格也都崩塌——这是 AI 产生巨大影响的结果。

所以,在人们设想的这种乌托邦/反乌托邦情景里,不存在“人人都变穷”的结局。事实上,恰恰相反。

因为价格崩塌,大家会变得富裕得多;而对那些由于某些原因找不到工作的人,社会安全网也更容易负担。

所以,也许我们会走到那种情景。

我是说,我乐观的那一面会说:是的,也许 AI 真有那么强大;也许经济的其他部分也确实能调整来适应它;也许这会发生。

但那样的结果,会比人们想象的要“更像好消息”。

顺便说一句,我刚才描述的一切,都只是基于最基本经济学的一种非常直接的外推。我并没有在做什么大胆预测。这只是一个直接的、机械的过程:当你拥有更高的生产率增速时,它就会自行展开,而更高的生产率增速必然来自更快的技术进步。

所以,讲清楚一点,我认为我们面对的世界,并不会像乌托邦派以为的那样被彻底改造,也不会像反乌托邦派以为的那样被彻底改造。

我觉得它会更偏向渐进式。

但我认为这种渐进式的变化,整体上将是一个利好的过程。即便它快得多,也同样是一个利好的过程——只是会以我刚才描述的另一种方式成为好消息。

If You're Freaking Out About A Future Jobless AI Dystopia... | Tyler Durden, Zerohedge

Amid an armada of dystopian futurists, projecting linear thoughts into a future of 'AI uber alles', Marc Andreessen stands as a beacon of potential utopian light, seeing a future that looks very different and very positive for young and old alike.

In a brief few minutes, the co-founder of Netscape and VC firm Andreessen Horowitz (a16z) believes instead that we are living through a unique (and most incredible) time in history with the rise of AI coming right as human civilization needs it...

"we're going to have AI and robots precisely when we actually need them [with populations shrinking] to keep the economy from actually shrinking."

Simply put, Andreessen says that fears of AI-driven mass job loss are overly simplistic.

After decades of unusually slow technological change and low job churn, AI could restore historical productivity levels (exemplified by the period from 1870-1930), sparking opportunity, innovation, and net job growth rather than displacement.

Declining populations and reduced immigration will make human labor increasingly valuable. AI's timing is "miraculous", Andreessen exclaims, preventing economic shrinkage from depopulation.

In even radical scenarios, explosive productivity leads to output gluts, collapsing prices, and massive real-wealth gains - equivalent to "giant raises" for everyone - while making safety-nets more affordable.

Whether incremental or transformative, Andreessen sees the outcome as fundamentally positive economic news.

"...there's all this concern among young people that their jobs are not going to be there for them. AI is replacing them..."

Andreessen replies (emphasis ours):

So the job-substitution/job-loss thing is very reductive. I think it's an overly simplistic model. And again it goes back to what I said at the very beginning which is we've actually been in a regime for 50 years of very slow technological change in the economy... like at half the rate of the previous era and a third the rate of like 100 years ago.

And so we're coming out of this kind of phase where we've had like almost no technological progress in the economy. We've had remarkably little job churn as a result of that relative to any historical period. And so even if AI triples productivity growth in the economy, which would like be a massively big deal, it would take us back to the same level of job churn that was happening between 1870 and 1930.

And if you go back and you read accounts of 1870 to 1930, people just thought the world was awash with opportunity. Right? At that rate of technological transformation, kids were able to develop new careers into new areas of the economy, building new kinds of products and services. A huge part of everything in our modern world today was kind of invented and proliferated during that period.

And so even if AI triples the pace of economic change in the economy, it's going to translate to a much higher rate of economic growth; it's going to translate to a much higher rate of job growth. And there will be some level of like task level and job level substitution that will take place but that will be swamped by the macro effects of economic growth and innovation that will happen and that then corresponding to that there will be hiring blooms quite honestly I think all over the place

And then again go back to the fact that this is all happening in the face of declining population growth and increasingly population shrinkage. So human workers in many, many, many countries over the next you know 10, 20, 30 years are going to be at more and more of a premium, literally because you're going to have shrinking population levels.

[While] we don't really want to get into you know politics particularly but it does feel like the world broadly is going to reverse course on the rates of immigration that we've had for the last 50 years. it seems to be kind of a broad-based thing happening - rise in nationalism, concerns about the rate of immigration - and immigration historically in countries like the US ha ebbed and flowed over time based on how the national mood shifts.

And so in a country like the US (or any country in Europe), if you combine declining population with less immigration, the remaining human workers are going to be at a premium not at a discount. And so I think that the combination of faster productivity growth, faster economic growth, and then slower population growth and less immigration - actually means there's going to be much less of this kind of dystopian/no-jobs thing. I just think it's probably totally off-base.

"That is extremely interesting. So, what I'm hearing is you're not super worried about job loss. Is the key here that the timing kind of just works out, this population decrease, you know, like all these kind of have to line up for there not to be this massive job loss with AI?"

Andreessen replies (emphasis ours):

Yeah.

Well, look, if we didn't have AI, we'd be in a panic right now about what's going to happen to the economy. Right? Because what we what we'd be staring at is a future of depopulation and depopulation without new technology would just mean that the economy shrinks. Right?

So it would mean that the economy kind of itself kind of shrinks over time, the opportunity diminishes, and there are no new jobs, there are no new fields. There's no new source of consumer demand for spending on things. And so you would be very worried about going into period of severe decline or stagnation.

Essentially you'd be looking at these very dystopian scenarios of like an economy self-euthanizing over time.

So you'd be very worried about the opposite of what everybody thinks that they're worried about. The only reason we're not worried about that is because we now know that we have the technology that can substitute for the lack of population growth and also for the for the lack of immigration that's likely.

And so, I would say the timing has worked out miraculously well in the sense that we're going to have AI and robots precisely when we actually need them, to keep the economy from actually shrinking.

And that's just like a fundamentally good news story.

To get to the mass-job-loss thing that people are worried about, you'd have to look at like far, far, far higher rates of productivity growth. You'd have to look at rates of productivity growth that are 10, 20, 30, 50% a year - something like that - which are orders of magnitude higher than we've ever had in any economy in the history of the planet.

It's possible that we get that. I mean, look, I have my utopian temptation along with everybody else.

If AI radically transforms everything overnight, then maybe... let's play out the kind of utopian scenario.

You get to a much higher level of productivity growth.

You get to a much higher level of technological change.

Corresponding to that you'll have a massive economic boom.

You'll have massive growth in the economy and then corresponding with that you'll have a collapse in prices.

And so the price of goods and services that are affected by (or commoditized by) AI will collapse.

There'll be price deflation and then as a consequence of price deflation everything that people are buying today gets a lot cheaper and that's the equivalent of a gigantic increase in wealth right across the society.

This is actually worth talking about because people I think people get kind of sideways on this issue.

So if AI is going to transform the economy as much as the utopians or dystopians (or whatever kind) think that it will, the necessary economic calculation of what happens is massive productivity growth.

The consequence of massive productivity growth literally means mechanically more output requiring less input, right?

So you get more economic output for less input, right? So you're substituting in AI for human workers.

And as a consequence, you get like this massive boom in output with much lower input costs.

The result of that is you get lots of goods and services in all those affected sectors. The result of those gluts is you get collapsing prices, right?

The collapsing prices mean that the thing today that cost you $100 now cost you $10 and now cost you $1.

That's the equivalent of giving everybody a giant raise, right?

Because now they have all this additional spending power.

That additional spending power then translates to economic growth, right?

The development of new fields. Everybody's materially much better off very quickly. And then by the way, to the extent that you do have unemployment coming out the other side of that, it's now much cheaper to provide the kind of social safety net to prevent people from being immiserated, right?

Because the prices of all the goods and services that a welfare program has to pay from, they're all collapsing, right? And so the price of healthcare collapses, the price of housing collapses, the price of education collapses, the price of everything else collapses because of the incredible impact that AI is having.

And so in this kind of utopian/dystopian scenario that people have, there's no scenario in which everybody's just poor. In fact, it's quite the opposite.

Everybody gets a lot richer because prices collapse and then it's actually much easier to pay for the social safety net for the people who, for some reason, can't find a job.

And so, maybe we end up in that scenario.

I mean, the optimistic part of me says, yeah, maybe AI is that powerful and maybe the rest of the economy can actually change to accommodate that and maybe that'll happen.

But the result of that is going to be a much better news story than people think it's going to be.

Everything I've just described, by the way, is just a very straightforward extrapolation on very basic economics. I'm not making any like bold predictions in what I just said. This is just a straightforward mechanical process that plays itself out if you have higher rates of productivity growth, which are necessarily the results of higher rates of technological growth.

And so, to be clear, I think we're looking at a world that's not like radically transformed the way that maybe the utopians think that it will be or the dystopians think it will be.

I think it'll be more incremental.

But I think that incremental shift is overwhelmingly going to be a good news process. And then even if it's much faster, it's also going to be a good news process. It'll just be a good news process in the other way that I described.

在一支反乌托邦未来主义者的舰队之中,他们把线性的思考投射到一个“AI 至上”的未来;而马克·安德里森却像一座潜在乌托邦之光的灯塔,看到的未来截然不同——对年轻人和老年人都同样积极。

在短短几分钟里,这位 Netscape 联合创始人、风投公司 Andreessen Horowitz(a16z)的联合创始人反而认为,我们正经历着历史上一个独特(且最令人惊叹)的时期:AI 的崛起恰好发生在人类文明最需要它的时候……

"我们将恰在真正需要它们的时候拥有 AI 和机器人[在人口萎缩之际],从而让经济不至于真的萎缩。"

简单来说,安德里森认为,对 AI 驱动的大规模失业的担忧过于简单化。

在经历了数十年异常缓慢的技术变革与低水平的岗位更替之后,AI 可能把生产率拉回历史常态(1870—1930 年便是例证),带来机会、创新以及净就业增长,而不是把人挤出岗位。

人口下降与移民减少将让人类劳动越来越值钱。安德里森感叹,AI 出现的时机“堪称奇迹”,它能避免因人口减少导致的经济收缩。

即便在更激进的情景中,生产率的爆炸式提升也会导致产出过剩、价格崩塌,以及巨大的实际财富增长——等同于给每个人“巨大加薪”——同时也让社会安全网更负担得起。

无论是渐进式变化还是颠覆性转变,在安德里森看来,其结果从根本上都是利好的经济消息。

"……年轻人非常担心将来没有他们的工作岗位了。AI 正在取代他们……"

安德里森回应道(重点为我们所加):

所以,把问题归结为“岗位替代/失业”是非常简化的。我觉得这是一种过于简单的模型。而且这又回到了我一开始说的:过去 50 年里,我们的经济实际上处在一个技术变革非常缓慢的阶段……大概只有此前那个时代的一半速度、也只有大约 100 年前的三分之一。

因此,我们正走出这样一个阶段:经济中几乎没有技术进步。与任何历史时期相比,由此带来的岗位更替都少得惊人。所以,即便 AI 把经济中的生产率增速提高到三倍——这当然会是件大事——也只是把我们带回到 1870—1930 年之间那种岗位更替的水平。

而如果你回去读一读 1870 到 1930 年的记述,人们只是觉得世界到处都是机会,对吧?在那样的技术变革速度下,年轻人能够在经济的新领域开辟新的职业,创造新的产品与服务。我们今天现代世界中的很大一部分东西,基本都是在那个时期被发明出来并迅速普及的。

所以,即便 AI 把经济变化的速度提高三倍,也会转化为更高的经济增速;也会转化为更高的就业增长率。确实会发生一定程度的任务层面和岗位层面的替代,但它会被经济增长与创新带来的宏观效应所淹没;相应地,说实话,我认为各个地方都会出现招聘的“井喷”。

再回到一个事实:这一切发生在全球人口增速下降、甚至越来越多地转向人口收缩的背景下。所以,在接下来你知道的 10 年、20 年、30 年里,许许多多国家的人类劳动者将越来越稀缺、越来越“值钱”,字面意义上就是因为人口规模在缩小。

[虽然] 我们并不太想特别谈政治,但看起来全球总体上会在过去 50 年的移民速度上掉头。似乎这是一种广泛发生的趋势——民族主义抬头、对移民速度的担忧——而在像美国这样的国家,历史上的移民规模也一直会随着国民情绪的变化而起起落落。

因此,在像美国(或欧洲任何国家)这样的地方,如果把人口下降与移民减少叠加起来,剩下的人类劳动者会更“值钱”,而不是更便宜。所以我认为,更快的生产率增长、更快的经济增长,再加上更慢的人口增长和更少的移民——这套组合实际上意味着那种反乌托邦式的“没有工作”情形会少得多。我觉得那种担忧很可能完全偏了方向。

"这太有意思了。也就是说,我听到的是你并不是特别担心失业。关键在于时机恰好对上了——人口下降之类的因素,你知道,要让 AI 不造成这种大规模失业,似乎得这些条件都凑在一起?"

安德里森回应道(重点为我们所加):

对。

你看,如果没有 AI,我们现在就会为经济将会怎样而恐慌,对吧?因为我们将面对的是一个人口减少的未来,而在人口减少却没有新技术的情况下,就意味着经济会萎缩,对吧?

这意味着经济会随着时间自己慢慢缩小,机会减少,没有新工作、没有新领域;也没有新的消费需求来源,让人们在各种东西上花钱。因此,你会非常担心进入一个严重下滑或停滞的时期。

本质上,你看到的会是那种极其反乌托邦的情景:经济在时间里“自我安乐死”。

所以,你真正该担心的,恰恰是与大家以为自己在担心的东西相反的方向。我们之所以不那么担心,是因为我们现在知道:我们拥有可以替代人口增长不足、也可以替代未来可能出现的移民不足的技术。

因此,我会说时机在某种意义上奇迹般地对上了:我们将恰在真正需要它们的时候拥有 AI 和机器人,让经济不至于真的萎缩。

这从根本上就是一个好消息。

要走到人们担心的那种“大规模失业”,你得看到远远、远远、远远更高的生产率增速。你得看到那种每年 10%、20%、30%、50% 的生产率增长——大概这种量级——这比地球历史上任何经济体曾经达到过的水平高出好几个数量级。

也不是不可能出现这种情况。我的意思是,你看,我和所有人一样,也会被乌托邦的想象所诱惑。

如果 AI 一夜之间彻底改变一切,那么也许……我们来推演一下那种乌托邦式的情景。

你会得到高得多的生产率增速。

你会得到高得多的技术变革速度。

相应地,你会迎来一场巨大的经济繁荣。

经济会大幅增长,而随之而来的,是价格的崩塌。

于是,那些受到 AI 影响(或被 AI 商品化)的商品与服务的价格会崩塌。

会出现通货紧缩;而通缩的结果是,人们今天购买的一切都会便宜得多,这等同于全社会范围内财富的巨大增加。

这其实值得讲一讲,因为我觉得人们在这个问题上常常会走偏。

所以,如果 AI 真会像乌托邦派或反乌托邦派(不管哪一派)所认为的那样深刻地改造经济,那么接下来必然发生的经济学推导,就是生产率大幅提升。

生产率的大幅提升,从机制上说,就意味着用更少的投入获得更多的产出,对吧?

也就是用更少的投入得到更多的经济产出,对吧?于是你用 AI 来替代人类劳动者。

结果就是,在投入成本大幅降低的同时,产出出现巨大的扩张。

这样一来,在所有受影响的部门,你会看到大量商品与服务涌现。过剩的结果就是价格崩塌,对吧?

价格崩塌意味着:今天要花你 100 美元的东西,明天变成 10 美元,再后来变成 1 美元。

这就等同于给每个人来一次巨额加薪,对吧?

因为他们现在拥有了额外的购买力。

而这份额外购买力又会转化为经济增长,对吧?

新领域随之发展起来。每个人的物质生活都会很快明显改善。而且顺带一提,如果在这一切之后确实出现一定失业,那么提供那种社会保障网、防止人们陷入困苦,也会变得便宜得多,对吧?

因为福利项目需要支付的那些商品与服务的价格都在崩塌,对吧?于是医疗价格崩塌、住房价格崩塌、教育价格崩塌,其他一切的价格也都崩塌——这是 AI 产生巨大影响的结果。

所以,在人们设想的这种乌托邦/反乌托邦情景里,不存在“人人都变穷”的结局。事实上,恰恰相反。

因为价格崩塌,大家会变得富裕得多;而对那些由于某些原因找不到工作的人,社会安全网也更容易负担。

所以,也许我们会走到那种情景。

我是说,我乐观的那一面会说:是的,也许 AI 真有那么强大;也许经济的其他部分也确实能调整来适应它;也许这会发生。

但那样的结果,会比人们想象的要“更像好消息”。

顺便说一句,我刚才描述的一切,都只是基于最基本经济学的一种非常直接的外推。我并没有在做什么大胆预测。这只是一个直接的、机械的过程:当你拥有更高的生产率增速时,它就会自行展开,而更高的生产率增速必然来自更快的技术进步。

所以,讲清楚一点,我认为我们面对的世界,并不会像乌托邦派以为的那样被彻底改造,也不会像反乌托邦派以为的那样被彻底改造。

我觉得它会更偏向渐进式。

但我认为这种渐进式的变化,整体上将是一个利好的过程。即便它快得多,也同样是一个利好的过程——只是会以我刚才描述的另一种方式成为好消息。

Declining populations and reduced immigration will make human labor increasingly valuable. AI's timing is "miraculous", Andreessen exclaims, preventing economic shrinkage from depopulation.

And so even if AI triples productivity growth in the economy, which would like be a massively big deal, it would take us back to the same level of job churn that was happening between 1870 and 1930.

And if you go back and you read accounts of 1870 to 1930, people just thought the world was awash with opportunity. Right? At that rate of technological transformation, kids were able to develop new careers into new areas of the economy, building new kinds of products and services. A huge part of everything in our modern world today was kind of invented and proliferated during that period.

And so even if AI triples the pace of economic change in the economy, it's going to translate to a much higher rate of economic growth; it's going to translate to a much higher rate of job growth. And there will be some level of like task level and job level substitution that will take place but that will be swamped by the macro effects of economic growth and innovation that will happen and that then corresponding to that there will be hiring blooms quite honestly I think all over the place

And then again go back to the fact that this is all happening in the face of declining population growth and increasingly population shrinkage. So human workers in many, many, many countries over the next you know 10, 20, 30 years are going to be at more and more of a premium, literally because you're going to have shrinking population levels.

[While] we don't really want to get into you know politics particularly but it does feel like the world broadly is going to reverse course on the rates of immigration that we've had for the last 50 years. it seems to be kind of a broad-based thing happening - rise in nationalism, concerns about the rate of immigration - and immigration historically in countries like the US ha ebbed and flowed over time based on how the national mood shifts.

And so in a country like the US (or any country in Europe), if you combine declining population with less immigration, the remaining human workers are going to be at a premium not at a discount. And so I think that the combination of faster productivity growth, faster economic growth, and then slower population growth and less immigration - actually means there's going to be much less of this kind of dystopian/no-jobs thing. I just think it's probably totally off-base.

"That is extremely interesting. So, what I'm hearing is you're not super worried about job loss. Is the key here that the timing kind of just works out, this population decrease, you know, like all these kind of have to line up for there not to be this massive job loss with AI?"

Andreessen replies (emphasis ours):

Yeah.

Well, look, if we didn't have AI, we'd be in a panic right now about what's going to happen to the economy. Right? Because what we what we'd be staring at is a future of depopulation and depopulation without new technology would just mean that the economy shrinks. Right?

So it would mean that the economy kind of itself kind of shrinks over time, the opportunity diminishes, and there are no new jobs, there are no new fields. There's no new source of consumer demand for spending on things. And so you would be very worried about going into period of severe decline or stagnation.

Essentially you'd be looking at these very dystopian scenarios of like an economy self-euthanizing over time.

So you'd be very worried about the opposite of what everybody thinks that they're worried about. The only reason we're not worried about that is because we now know that we have the technology that can substitute for the lack of population growth and also for the for the lack of immigration that's likely.

And so, I would say the timing has worked out miraculously well in the sense that we're going to have AI and robots precisely when we actually need them, to keep the economy from actually shrinking.

And that's just like a fundamentally good news story.

To get to the mass-job-loss thing that people are worried about, you'd have to look at like far, far, far higher rates of productivity growth. You'd have to look at rates of productivity growth that are 10, 20, 30, 50% a year - something like that - which are orders of magnitude higher than we've ever had in any economy in the history of the planet.

It's possible that we get that. I mean, look, I have my utopian temptation along with everybody else.

If AI radically transforms everything overnight, then maybe... let's play out the kind of utopian scenario.

You get to a much higher level of productivity growth.

You get to a much higher level of technological change.

Corresponding to that you'll have a massive economic boom.

You'll have massive growth in the economy and then corresponding with that you'll have a collapse in prices.

And so the price of goods and services that are affected by (or commoditized by) AI will collapse.

There'll be price deflation and then as a consequence of price deflation everything that people are buying today gets a lot cheaper and that's the equivalent of a gigantic increase in wealth right across the society.

This is actually worth talking about because people I think people get kind of sideways on this issue.

So if AI is going to transform the economy as much as the utopians or dystopians (or whatever kind) think that it will, the necessary economic calculation of what happens is massive productivity growth.

The consequence of massive productivity growth literally means mechanically more output requiring less input, right?

So you get more economic output for less input, right? So you're substituting in AI for human workers.

And as a consequence, you get like this massive boom in output with much lower input costs.

The result of that is you get lots of goods and services in all those affected sectors. The result of those gluts is you get collapsing prices, right?

The collapsing prices mean that the thing today that cost you $100 now cost you $10 and now cost you $1.

That's the equivalent of giving everybody a giant raise, right?

Because now they have all this additional spending power.

That additional spending power then translates to economic growth, right?

The development of new fields. Everybody's materially much better off very quickly. And then by the way, to the extent that you do have unemployment coming out the other side of that, it's now much cheaper to provide the kind of social safety net to prevent people from being immiserated, right?

Because the prices of all the goods and services that a welfare program has to pay from, they're all collapsing, right? And so the price of healthcare collapses, the price of housing collapses, the price of education collapses, the price of everything else collapses because of the incredible impact that AI is having.

And so in this kind of utopian/dystopian scenario that people have, there's no scenario in which everybody's just poor. In fact, it's quite the opposite.

Everybody gets a lot richer because prices collapse and then it's actually much easier to pay for the social safety net for the people who, for some reason, can't find a job.

And so, maybe we end up in that scenario.

I mean, the optimistic part of me says, yeah, maybe AI is that powerful and maybe the rest of the economy can actually change to accommodate that and maybe that'll happen.

But the result of that is going to be a much better news story than people think it's going to be.

Everything I've just described, by the way, is just a very straightforward extrapolation on very basic economics. I'm not making any like bold predictions in what I just said. This is just a straightforward mechanical process that plays itself out if you have higher rates of productivity growth, which are necessarily the results of higher rates of technological growth.

And so, to be clear, I think we're looking at a world that's not like radically transformed the way that maybe the utopians think that it will be or the dystopians think it will be.

I think it'll be more incremental.

But I think that incremental shift is overwhelmingly going to be a good news process. And then even if it's much faster, it's also going to be a good news process. It'll just be a good news process in the other way that I described.
