      • 家园 真是技术迷信的典型

        你的逻辑很奇怪啊,一切软件计算机都可以生产,制造业倒反而离不开人了;真是软件生产都全自动化了,还有什么不可以全自动化,自动化不就是软件控制吗?

        不过在我看来,在下面各贴所提出的农业、能源等实际问题得到解决之前,这些都是“无稽之谈”(引用你的话)的空想,所以我是决不会杞人忧天的担心什么被计算机开除球籍的。

        诸如

        信息革命让人类进入了一个全新的进化时代,从人类历史角度说,类似人类产生了语言文字,从生物进化角度说,类似自然界出现了人这种生物。在这个时间跨度上,思考文科理工科或者中国崩溃论是无稽之谈

        之类。请慎重考虑一下,自然界演化出人类经历了多少年,人类发展出语言文字又经历了多少年。

        那么阁下在这个世上存活了多少年?盖茨多少年?那个凡身肉体被捧成资本主义偶像的乔布斯不是已经死了吗。。。

        在自然界面前,在人类历史面前,还是谦虚一点。或许50年后,盖茨之流,就不仅渺小,甚至成为笑柄。

        最后给你一个建议,除非确有必要,不要在写作和说话时动不动就把中英文混杂在一起。如果你人在国外,长此以往,祖国语言会荒废的。如果你人在国内,就更属于,(那句歇后语不太文明,不说了),多此一举。

        • 家园 呵呵,看来lz“抛砖引玉”不过是附庸风雅了,领教了

          连中英文混杂都可以被刺激到,在这个英文是事实世界语的年代还要费心去找歇后语,太劳您大驾了。不过我的确人不在中国日久,您先将就吧,再说荒废语言之说似乎离题万里了,不劳操心了。

          这些无聊口水放下不提,咱说回正事,光说楼下这些能源,生产自动化的贴子,我都读了。之所以在信息革命时代都不是问题,当然需要假以时日解决,在于一旦计算机的能力超越了人类的智力水平(以科学最前沿为代表),在那一天之后,人类现在面临的对自然界能源的未知,未解难题,会出现多大的进展,这本身都是超越人目前的想象力的。那么我们以目前的科学水平的理解范围做为基准来评价社会历史在未来的变化不是很可笑的一件事么?比如,谁会说左右人类历史的能源问题在下一个百年之中仍然不会得到突破而不再成为政经争端的头等话题呢。甚至人本身的寿命可能被延长超过百年现在都被预计有可能在一代人内实现,那么我们思考问题的方式是不是应该看得更远些,看得超越“凡身肉体”一些?

          虽然这样的可能性从理论上讲自从发明了计算机之后一直都存在,但是直到最近信息革命的进步才让人们对其发展能够对人类产生多大的影响有了更深刻的了解。其中就包括,这个进步最重要的还不是进步这个事实本身,而是进步的速度甚至其加速度。几千年几万年的发展与最近几十年的发展的对比,让人们认识到,以往的想象,不只是在科幻小说,而是切切实实有了更直观的感受,因此改变了许多人的世界观。当然还有更多的人由于信息流通的迟滞或个人性格上的主观原因,对此仍然抱持传统的观点,以为科幻的“无稽之谈”自然不在少数,甚至是99%中的主流。

          无疑,绝大多数的我们是看不到未来的广泛世界,但是同样无疑的是人类总是会感念那些在关键时刻为人类文明发展伸出神来之手的人,如果lz真的对历史谦逊的话,应该发现这个规律。这样的人当然不是那些王侯将相,甚至不是1%的绝大多数,但是这样的人中有发明电的爱迪生,发明蒸汽机的瓦特,爱因斯坦,牛顿,等等,同样也有第一个发明轮子的人,第一个发明文字的人,如果这些人的名字可知的话,这样的人中同样也包括信息时代的盖茨与乔布斯。人类中这些人的作用与影响不但不会随着时间而变得渺小或成为笑柄,而是肯定会超越这个时代而被纪念的,成为笑柄的最后往往是那些把这些人当作笑柄嘲笑的人自己。甚至最近的例子就包括信息业内部的比如黑莓手机等,假以时日,这个世事弄人的例子还会扩大到超出手机业,超出信息业的。

          同样也给你一个建议,不要让自己的所知限制了自己的所想。引一句也是使用英文而不是其祖国母语的人的话:imagination is more important than knowledge。看不懂的话,国内的各式翻译软件到出都是,随看随翻的都很多,强烈建议lz使用,有益帮助开阔眼界,也开括心胸,这后一点甚至更为重要。现代的行万里路读万卷书,不一定必须要飞到巴黎去买LV,跑到伦敦去读贵族学校那样,也可以简单的通过互联网(哪怕是围墙中的)去看世界,读网页,当然前提是你要接受自己母语不是全世界都用,自己所想不是全世界所想这个事实。

          • 家园 本人还没有迷信到将英语崇拜为世界语的程度

            另外,“世界语”这个名词要慎用,有一种语言就叫世界语,你把英语说成世界语,说世界语的人会抗议的。

            虽然我的英语自认也属于缺斤少两,但我估计我英语的斤两比你还是要足一些。我出国年头也不少了,但多年来一直坚持在说、写汉语时决不夹杂异国语言。这是我对祖国语言的珍惜。当然,人各有志,这个建议你不接受是你的自由。

            你知道什么是迷信吗?就是在没有事实和关于事实的证据的情况下,盲目地相信自己想要相信的东西。

            把你的一切命题,什么“计算机超越人的智力水平”,什么以“目前的科学水平为基准...是很可笑的一件事情”,还有什么“人的寿命可能延长超过百年”(当然,这里肯定指的不是个别长寿老人),如果都换成“上帝存在、上帝是造物主”,又有什么根本的不同吗?虔诚的教徒尚且还可以找出很多迹象来说明造物主的存在呢。。。

            据此我们还可以推理,只要我们相信你说的这些命题(只要我们相信上帝),那么什么能源问题、粮食问题,乃至目前的经济、失业问题,都可以不去管它。。。到时自然有奇迹发生。就是这个意思吧?

            至于你列举的那些人名,别人我不敢说,爱因斯坦肯定是羞与盖茨、乔布斯之类为伍的。原因吗,建议你读爱因斯坦的“我为什么赞成社会主义”,你既然通晓世界语,又知道到哪里可以找到翻译软件,想来读懂不是问题。

            最后,你提到进步的加速度问题,那么你知道一种事物如果一直加速度地膨胀、增长最后结果会怎样吗?有两个例子,一,可以拿你的汽车引擎试试,二,癌细胞。。。

            • 家园 我原来不肯定什么叫迷信了,刚看了lz的贴恍然大悟了

              后补:http://www.ccthere.com/article/3590671

              -----------------------------------------------

              lz说

              你知道什么是迷信吗?就是在没有事实和关于事实的证据的情况下,盲目地相信自己想要相信的东西。

              显然事实在其中的作用很大,那么我们看看什么是事实。

              1.英语做为流通最广的语言,与世界上人口最多国家的学校中第一外语,所以有了个“事实”世界语这么个称号。相反那个lz口中的世界语从流通上说比英语差的天壤之别,那么枉顾这样的事实而将称英语为世界语为迷信,是不是个打着反迷信的旗子行迷信之实的行为呢?

              2.我在贴中不但不会使用中英文混合造句,而且是引用英文原句来加强语气,虽然对英文程度低的读者不产生效果,但对lz这样号称英文极佳的读者并在国外日久,枉顾在中国以外的华语世界中英文的广泛应用,甚至各种语言彼此的影响而产生外来语词的大量事实,刻意强调在中文中出现英文就是对汉语的不珍希,如此形而上学的矫情,是在向别人显示自己对“爱国”,“祖国”这些语境的崇拜与迷信么?

              3.我从头贴就说我是从杂志新闻中获得的信息,根据我提供的信息在互联网上找到出处并不是什么难事,所有我说到的有可以找到相关文献与科研人员的资料,包括“计算机超越人的智力水平”“人的寿命可能延长超过百年”。不以自己的孤陋寡闻为意,枉顾事实的将其称为可以上帝教徒比喻,lz对自己的思维理解能力的如此着迷,倒是让人对“迷信”有了完全暂新的定义。

              4.事实有时在lz眼中也可以做为一件想穿就穿想脱就脱的衣服。我将哪些人名列在一起代表了一种观点,与那些人个人认可与否自然无关,因为大家都是旁观者。lz竟然说:“别人我不敢说,爱因斯坦肯定是羞与盖茨、乔布斯之类为伍的”。我倒,lz原来连死人在今天这个世界对未闻之事的想法都知道,这种对“事实”的全新定义,又一次让我对lz的崇拜如滔滔江水。。。

              总而言之,我完全想通了,诚心接受lz的建议,从此改崇拜lz迷信lz了。

              另外,我瞎猜一下,西西河里罗教主与lz应该是引为知己的。如果不是的话,我是很高兴为lz引荐一下的,有空多亲近才是。

    • 家园 说到理工科思维,这两天微软创始人Paul Allen在讲

      Singularity的不可能近期实现。不过看其文章下面的回帖很有感慨,可以说人类社会的近代史就是技术革命的近代史。而未来呢,历史恐怕已经不能做为未来的指标了。

      有个回帖提到了眼下华尔街的事,1%与99%在那个时刻到来之前会发生什么,也许现在华尔街的事就是正剧前的序幕。

      中国现在的格局不过是正在快速向这个1%与99%的形势转化中的一个前奏,政治必然为利益服务,何况是自己主动融入的这个全球生态圈,河里左左右右的瞎吵,不得要领,时代的车轮上不以个人好恶为转移的,会发生的就一定会发生,只是时间地点不可知罢了,达尔文的这套以后会被证明超越一切人类先贤的哲学思想,过去的一切都是浮云,只有未来才是神马,这其中只有达尔文看出了天机,连人这个生物本身都是一个过客,还吵什么吵。

      Re: You Don't need Human Intelligence for the Singularity

      I've been wondering the same thing for many years now. The problem of course is that you can automate a great deal of mundane tasks, and hand production over to robot factories for better, higher quality, lower cost production. Most intellectual tasks such as accounting can be handled by computers. Most service tasks can be handled by automated voice systems (though at present they are rather awful, that need not be the case, and they could be improved), etc.

      In the end the question becomes "What will all of the surplus people do to earn a living?"

      The answer to that is very difficult to fathom. And begs another question... for whom is all of this automation being conducted if not for the purchasing public... but who will buy the products when no one is needed to do the work, and therefore produces no value, and therefore cannot earn money because money is an exchange of value? What will become of the masses of people who have no value in the economy because their productive use has been superseded by machines? Economy works that people gain money according to their value, and that value flows around the market aggregating capital where it can be put to productive use. However, this assumes that everyone can provide some value to the economy. When they can’t because the means of production are automated, then they are out of work, and have no income. There are several possible results.

      One is that people will not earn money, but be given credits by the system to spend. The problem is that this runs against the nature of economy, which is you gain income according to your value. If you have no value, then the only place you can gain income is from someone who does have value. And that would be the so-called 1% being protested in major cities around the country. Things have not come to the point where the 1% are the *only* ones who have value/income, but the article is in regards to future conditions, not present. So eventually, and perhaps quite soon, the 1% will be the only working members of society. So the solution in this case is to tax the 1% sufficiently to pay everything for the masses who have no jobs, but still want and need to buy things. Talk about robbing Peter to pay Paul! The 1% will literally be paying everyone else so they can buy the products they produce. Somehow, this just seems quite wrong. I don’t know for sure, but I strongly suspect it cannot be sustained. It runs too counter to common sense economics.

      What could it be? Ah. I see. The masses will have no work, and without work they will be prone to restless mob-like activity. Unless they are entertained, fed, and provided for in every way they will feel disenfranchised and angry. One step further and the political class will have an enormous ability to rally the mob on the grounds that the entire system is “unequal”. Why? Well, the reason the 1% got where they are is because they wanted to make a lot of money, and to maximize their profits and beat their competition they automated significantly in order to lower costs of production. Makes sense. But what happens when the masses of the Unworking see the vast wealth of the 1% and their politicians who represent them (the Leftists) argue, rant and rail that it’s all “unfair” that the 1% have jets and fancy cars and mansions, while the masses must live in modest two bedroom houses with small cars? The mob will roar and rage and since they have no jobs, no responsibility, and are inclined to be restless and somewhat angry anyway… they may just go ahead and burn the Factories down. Look at Britain recently. Tip of the ice berg? Could be!

      It’s fair to ask, what good will all the automation in the world do when the mobs burn down the factories? The answer to that, of course, is Automated Military Guardians to protect the factories, obviously. Terrorism? No problem. Automated facial recognition, and body motion-emotion detector systems will show the Robot Guardians immediately who is going to do some unauthorized vandalism and open fire with Taser Banks set on stun. Or Kill. Robot warriors will be the 1%’s security. So what will the mob do to vent it’s ever increasing rage? It will in all likelihood go after the 1% directly. As we are now seeing the beginning signs of in NYC with the Occupy Wall Street protesters marching uptown to the mansions of the super wealthy. When will that turn violent? This year? Next year? In 5 years? No one can say for sure. It could be tomorrow morning.

      In the end the Great Ones, the high and the mighty Industrialists, the 1% who own the production will have to sequester themselves away into communities where the mobs cannot get at them. An island here, a fortress there... all will be safe for the 1%. Unfortunately they will soon discover, this is really, in fact, no way to live. They will discover that they live in a huge prison called Planet Earth, on which they have vastly restricted freedom because the mobs will have at them at every opportunity.

      Let’s not forget as well that their computer systems will be flawed, due to the decades of poor computer development practices, and so even far away in the Swiss Alps, behind their huge stone barriers... they will still be subject to the predations of hackers. There will be, in fact, no place for them to hide. And so what happens when the Industrialists find themselves living on Prison Earth, with the seething mobs circling their fortresses, having nothing better to do but riot, and plot, and wait for the precious day when they can catch the 1% off their guard, or hack into their Robot Army and turn their mechanical behemoths against their fleshy Overlords?

      It would be a weird, regrettable, and sadly not entirely improbable outcome if things keep going in the current direction.

      That is one possible scenario. We can all hope it does not get like that. What other possibilities are there?

      Another one is to follow the example of Titus the one of the wise Emperors of Rome. When an inventor came to him with the first steam engine, the Emperor asked, “what can you do with it?”. The Inventor replied, quite joyfully no doubt, “why you can build machines to cut down forests, and build giant aqueducts! There is no limit to what the machines powered by steam can do!” The wise Emperor stood on his balcony overlook the vast wheat fields, forests, and cities of his domain, and concluded that he should lock the Inventor away, and hide the machine for all time. When he was asked why he did such a thing, he wisely noted that the machines would replace the workers, who would then be left idle, and with nothing to do they would become restless, easily agitated, and so destroy the world. He decided that outcome would not be in the best interests of either the common man, or the aristocracy, or humanity at large as it would inevitably lead to universal disaster. He was wise.

      So that is another option. Do away with automation in favor of manual production in order to avoid the consequences that would follow when everything is automated. To keep people working is better than maximizing efficiency or profits.

      That is another option, but one that probably requires a wise Emperor at the beginning of the process to execute against. At this point the option of turning off technology seems rather remote. We can possibly mitigate, perhaps delay, but we can no longer avoid the inevitable. Another solution is very likely required.

      Let’s try a Utopic fantasy solution then. How about a world in which automated factories are put in space so as to not pollute the planet? A world in which the masses do not produce products, but instead produce entertainment. The more entertaining they are, the more valuable. The planet becomes filled with people who sing and dance, do sports, tell stories, run games, and otherwise entertain each other, and this forms the basis of the economy, while the machines build the products that people buy.

      Still problems. What about people who are simply not very entertaining? Not everyone is a genius, an artist, or a story teller. It also does not solve the problem of the need for human inspiration… the feeling that untied we can move forward and keep our race growing and advancing? For that, I would suppose there is another option. Space. The final frontier. Exploration. We could build towards that. Another option, of course, is scientific advancement. While machines may be able to achieve vast powers of calculation… can we expect them to Think Outside of the Box? To come up with new and original ideas?

      Unfortunately, perhaps, the answer is yes, we can. Already people are working on computers that write songs that sound nice, act like humans and tell stories, and from the prognostications regarding Singularity one gets the impression that the machine-mind will far exceed the limited capacity of the human mind.

      Perhaps the machines will invite the humans to join them? There is a growing field of Biological-Computers that base their mechanisms on DNA. Will we fuse with the machines like the Borg? Or will we become Super-Beings with computer enhanced capabilities far beyond those of ordinary men?

      The future indeed is unpredictable. I for one remain at this point optimistic. As in every era, there are bright spots and dark spots, and much gray in the middle. During the terrors of World War II there were young couples who fell in love, got engaged, and started families. There were beautiful sunrises, and fields of flowers. I choose, for myself, to look for love, for sunrises, and for flowering fields. And I hope that in the end, the beauty intrinsic in life will overcome the dark possibilities that lurk beyond the shadows of the horizon.

      Re: You Don't need Human Intelligence for the Singularity

      I can think of several different scenarios for how this all works out:

      1) It won't happen: Maybe productivity growth can't exceed output growth. This is the classical economic prediction, because increased productivity implies cheaper goods and services, which causes everybody to buy more stuff, which causes output to grow faster than productivity. Unfortunately, I think there's a saturation point at which humans are unwilling to buy more stuff, because they're simply not getting any marginal return from nicer furniture, or tastier food, or healthcare that lets them live to be 900 instead of 800, or 25 hours of entertainment in a 24 hour day.

      2) Hyper-consumerism: Maybe the reason that consumption saturation doesn't occur is because technology allows us to consume more and more with no upper bound or, alternatively, it gives us access to new realms of goods and services that are very expensive and require lots of human mediation. Health care comes to mind. But it seems that tech that turns us into hyper-consumers also turns us into hyper-producers, and we're back to the same old problem.

      3) An adequately benign welfare state: If 75% of the population can be provided with healthy, happy (non-productive) lives for 25% of GDP, then the productive people (and their machines) can support the non-productive relatively painlessly. Note that individual humans aren't the only entities that pay taxes.

      4) Everybody's a stockholder: If everybody owns a chunk of the automated companies that are producing all the wealth, then maybe they live off the dividends and capital gains spun off from those companies. The problem here is how to provide folks the capital to buy into the companies in the first place. Ultimately, I don't think this is a lot different than the benign welfare state; it's just another way to redistribute wealth from the productive to the unproductive. (NB: This isn't necessarily a bad thing when goods and services are sufficiently cheap.)

      5) Torches and pitchforks: Too many angry, desperate, unproductive people become violent enough to degrade society to the point where productivity falls below growth, and the system stabilizes. Note that "stabilizes" in this context really means "collapses to a much lower-tech civilization."

      6) Dramatically reduced human population: It's all well and good to posit a practical welfare state, or the mass equivalent of a bunch of trust fund babies, but these all strike me as transient conditions. Ultimately, people have babies because they perceive an economic advantage to having them, or because they believe that their kids will live better than they did. No advantage or aspirations, no kids. Then, as long as people actually die (which is probably open to question), maybe things finally stabilize at a lower population. The problem with this is that, in a world where half of everybody is of below-average intelligence (OK, OK: below-median intelligence), a lower population doesn't really change the balance between the haves and the have-nots.

      7) Just don't go there: I'm about as rabid a free-market libertarian as you'll find anywhere, but given how grim most of the scenarios above are, I've recently started to wonder if Titus's solution might be the only way out of the problem. If we make it illegal for automation to displace humans, then we don't have a problem. Unfortunately, this is an insurmountably difficult collective action problem. Getting all countries to voluntarily cap their productivity is tantamount to getting them all to agree to stop competing with one another. Hey, it could happen...

      8) Transcendence: Of course if Kurzweil is right, then we are the machines eventually, and we don't have to worry those pesky unproductive people--we'll just wire 'em up to be productive. Maybe this is ultimately the only way out of the problem. But I have to say that a lot of these scenarios offer an uncomfortably plausible solution to the Fermi Paradox.

      我猜未来是第六条。

    • 家园 谈谈理工科思维、形而上学和技术革命迷信

      谈谈理工科思维、形而上学和技术革命迷信

      (提上来答复兰州人、山谷男孩、mmq、Endless等)

      有的网友可能知道,强国论坛有个数学网友,经常用“理工科思维”与文科网友(其实主要是右派网友)论战,颇收奇效。数学网友的方法,就是重事实、讲逻辑,往往根据辩论对手自己的逻辑推出与之相反的结论,这是对科学思维方法的正确应用,是好的理工科思维。

      我这里要讲的是另外一种理工科思维。随着资本主义的发展,科学技术的分支越分越细,从而绝大部分研究人员终其一生只从事一个十分狭小领域的工作。其结果,就是具体的研究人员往往对各个科学领域以及自然界、社会与人的认识领域之间的相互作用感到茫然,另一方面,更加不了解人类和自然界的历史演变和发展趋势。由于这种客观条件造成的认识局限,表现在思维和认识方法上,就是现代的理工科人士往往容易犯形而上学的毛病,通俗地说,就是只见树木,不见森林,一叶障目,孤立地、静止地看问题(当然实际上绝大多数所谓社会科学界人士也存在同样的问题)。

      表现在关于技术革命的认识上,就是往往会夸大技术革命的实际进步作用。当然,批评某些理工科人士存在夸大技术革命作用的问题,并不是要否定技术革命确实有的进步作用,而是说不能忽视技术革命对社会、对自然环境,以及长远的对其它技术领域可能产生的副作用。而如果看不到这些副作用,一味地强调某些技术革命的正面作用,那么就会产生事实上的对技术革命的迷信。具体来说,就是认为技术革命总是可以提高生产力,而忽视一定的、反动的生产关系对技术革命和生产力的破坏作用;以及认为,在长远技术革命可以解决一切问题,让人们生活永远变得更好,而无视生态环境和资源对人类物质消费的根本限制以及人类社会未必永远进步的根本哲学问题。

      如上所述,对这种形而上学的理工科思维的批评,并不是对理工科以及社会科学任何个人的责难,而是认为这是现代资本主义条件下科学技术发展必然面临的历史局限。资本主义,为了资本积累和利润最大化的需要,就要求将各种学科进行越来越细的分工,以便实现在短期迅速进行对资本积累有利的创新的目的。另外,这种相信技术进步可以解决一切问题、明天永远会更美好的意识形态,也是有利于资本主义生产关系的不断再生产,有利于资产阶级长期维持对无产阶级和小资产阶级的统治。

      对技术革命迷信的一种特定表现方式,就是往往会夸大我们生活在其中的某次“技术革命”的作用,认为它特别伟大,是前所未有的进步等。在与兰州人、山谷男孩、mmq、Endless的讨论过程中,往往发生这样的情况,双方各自列举在某些领域的技术进步现象,然后为这一现象到底是否代表根本性变化而争吵不休。

      当然,本人如实坦白,由于本人非理工科出身,在遇到具体技术问题举例的时候,往往比较苍白,或如某些网友所说的,比较肤浅。对此,本人完全承认(靠着这些年对石油峰值、气候变化等问题略有研究,能和诸位讨论讨论能源问题已经不错了,另外,有机会,会再写气候变化的帖子)。

      所以,下面,我要设法将讨论转移到对我略微有利的领域,经济学领域。但是,我进行转移的理由还是“冠冕堂皇”的,那就是,技术进步的成果最终要体现在经济增长率上。为什么这么说呢,因为技术革命的目的,尤其是现代资本主义条件下技术进步的目的,归根结底是为了提高劳动生产率(降低资本家的成本)以及在更广大的范围满足消费者的需求(扩大市场),而这些成果会综合反映在经济增长率上。

      当然,在资本主义的条件下,经济一般是增长的。所以,我们要比较的,不是绝对的经济增长率,而是与技术革命发生之前的时期相比,看某次技术革命是否造成经济增长加速,加速多少。

      20世纪上半期,可以认为属于第二次技术革命(石油、电、汽车、钢铁)的酝酿推广期,当时这些技术主要是在美国推广,只是到第二次世界大战以后才在世界范围全面推广。1900-1950年,世界经济年平均增长2%。当然,这其中包括了两次世界大战。如果只看第一次世界大战以前的1900-1913年,世界经济年平均增长2.5%。

      1950年以后,第二次技术革命在世界范围全面推广,1950-1970年,世界经济年平均增长4.9%。可以说,第二次技术革命大大促进了世界经济的增长,与20世纪上半期相比,在第二次技术革命的成熟发展期,经济增长加速了2.4-2.9个百分点。

      那么,上个世纪末以来的以计算机、因特网为代表的信息技术革命又怎样呢?1970-1995年,可以算做信息技术革命的酝酿推广期,在这个时期,世界经济年平均增长3.2%,增长速度下降,说明第二次技术革命的作用在西方已经全面枯竭。1995-2010年,可以算做信息技术革命的成熟发展期,标志就是计算机普遍进入普通家庭。而世界经济增长的情况怎样呢?在这个时期,世界经济年平均增长3.6%,与1970-1995年相比,仅仅增加了0.4 个百分点,大大低于第二次技术革命时期的近5%,其对经济增长的加速作用,远不能与第二次技术革命相比。

      需要说明的是,中国、印度等国家实际上还在进行第二次技术革命,所以现有的世界经济增长,实际上还包括了一部分第二次技术革命的功劳。不仅如此,现在世界经济增长已经呈现颓势,在未来的一二十年,世界经济增长很可能减速而不是加速。换句话说,所谓信息技术革命,刚刚掀起一个浪花,就要结束了。

      而世界的实际情况是,面对能源危机、生态危机越来越严重的现实,整个现代资本主义的无限增长的神话或许在本世纪上半期就会寿终正寝了。

      关于历年世界经济增长率,参见附图(被回帖挤到下面了,跳过美国利润率的图,下面一个图就是):

      • 家园 老兄的深入思考和细致观察让人佩服。

        尤其是地球资源对于人类物质追求的根本限制这一点,实际上已经为人类所认识,但是就是知不能行。

        我对这一点有不同的认识,资源不会限制人类,但是环境恶化是不允许人类无限制满足自己需求的。人类最终的道路,可能是充分利用太阳能。

        • 家园 过奖了

          单纯讲资源限制确实是片面的。不过我个人认为环境恶化和资源短缺同样构成对经济增长的不可克服的限制。

          环境恶化需要另外讨论。能源问题,因为油价上涨,人们有切身体会,还好说明一点。气候变化问题,理解的人就更少了。

      • 家园 个人认为,使用劳动生产力比经济增长率这个指标可能更好

        生产单位工农业产品所需要的人工和经过信息技术改造后所需人工做一个对比。因为信息技术革命,对几乎所有的国民经济行业都进行了改造。

        比如您可以研究一下传统的钢铁厂和使用先进IT技术改造(PLC, DCS,各种总线,数字传感器等等)的钢铁厂,其单位产品的能耗,原材料消耗,所需工人数量等等。

        举一个我所在行业的例子。2010年,我们公司生产的柴油机,其单位二氧化氮排放是2000年的1/10. 这个得以实现,主要得益于使用嵌入式计算机对喷油量和其他一些参数的精确控制。

        同样,您所说的环境,资源等问题,如果能得到解决的话,一样离不开信息技术的帮助。

        当然,劳动生产率提高了,对工人并不一定是好事,因为制造业需要的就业人数少了....

        • 家园 你说的这些我都同意

          但是请注意,在资本主义历史中,劳动生产率提高是常态。所以要比较的话,应该是将一个时期的劳动生产率的增长速度与另一个时期的劳动生产率的增长速度相比较(而不是简单地比较劳动生产率水平);再有就是应当对整个经济而不是个别部分做比较。

          信息技术对于解决环境资源问题有帮助,但是最根本的还是要减少消费。否则,如果技术进步率2%,而消费增加3%,那么技术进步不但没有抵消消费的影响,反而可能由于它使资源变得更加便宜,客观上起到加速资源枯竭、环境破坏的作用。

          另外,尽管我对技术潜力不那么乐观,但是还是要说明,如果在社会主义条件下,就不怕劳动生产率提高会导致工人失业。毛主席那时候就不怕失业吗;至于将来,如果劳动生产率提高了,普遍缩短劳动时间就是了。宁鸣的另外一个帖子引用官方报告说中国农民工的劳动时间现在仍然是平均每周60小时,倒是达到了英国工厂法以后10小时工作日的水平,减到每天8小时、7小时不好吗?劳动生产率再提高,就增加节假日啊,可以增加带薪休假啊。

      • 家园 这种技术革命和世界经济增长之间的关系推导

        只能说明你的确是“文科”思维。当然,我认为不存在什么文科思维,很多历史学家的严谨性不亚于理工科。

        社会学问题影响因素太多了,技术革命只是其中一个变量,你还必须排除其他变量的影响,否则什么稀奇古怪的结论都能得出。

        • 家园 那好啊,你给一个指标啊?

          给一个排除其它变量的方法啊。理工科思维,或者换个说法,严谨思维总要定量吧。

          怎么把众多的、不同类型的技术创新定量化,然后加在一起?

          网上讨论吗,差不多就行了。

      • 家园 信息革命也可能还没有结束,也不一定以电脑进入家庭为标志
        • 家园 信息革命还远远没有结束。全人类有多少人可以上网啊?

          WHATEVER的观察不错,但是也不能夸大信息革命的影响。我倾向于量变引起质变,现在量变还远远没有到结束的时候,就宣称要质变到来或者快要结束,都是不合适的。

          信息革命,应该是深刻地改变我们的生活方式。现在已经出现了这种趋势,但是还谈不上深刻。拭目以待。
