1. 考研问题 想过很多,不知道怎么办了

首先先考虑自己的学业问题,重视自己的学习状态和想法,决定自己以后想要做什么,就可以了,考研也只是以后的一个出路而已

2. 元宇宙会展到底是啥,会催生下一个“会展新世界”吗

生命 其实也可以是一首诗如果你能让我慢慢前行静静盼望 搜寻怀带着逐渐加深的暮色经过不可知的泥淖在暗黑的云层里终于流下了泪 为所有

3. 元宇宙概念究竟是什么意思

元宇宙它就是指通过VR或者AR设备进入到一个虚拟的空间里面去,然后人们可以在这一个虚拟的空间里面去进行自由的社交工作,或者其他的一些事情。元宇宙概念,它主要是指在股票市场里面那一些元宇宙相关的概念股。因为市场最近在对这一些概念,进行着热烈的炒作。但是也有一些声音是反对元宇宙的发展,他们认为元宇宙会把人们带偏。

一.元宇宙

不知道大家是否看过一个电影叫做《头号玩家》。元宇宙想要实现的愿望,就是类似于这一个电影的那一种情况。人们可以通过头戴式AR或者VR设备进入到一个虚拟的世界里面,这个世界也就叫做元宇宙。在这一个世界里面它的东西都是具有价值的,通过区块链技术能够实现认证。就像是前一段时间某一些明星,他们去花了几百万甚至几千万美元,去购买了一个nft头像,就是属于元宇宙资产。

4. 清华大学发布清华简最新研究成果,这一次成果有多重要

这一次的成果基本上推动了相关行业的发展,而且拥有了最新的技术。

5. 讨论利用VR/AR/XR等实感成像技术实现元宇宙平台的商业模式

摘要元宇宙的发展可划分为四个阶段,当下处于以 PC、移动端为接口的准 元宇宙阶段。狭义而言,元宇宙是以 XR、AI、区块链三大技术为核心搭 建的下一代互联网生态,其中 XR 技术(VR/AR/MR/脑机接口等)是实 现沉浸感的关键技术,XR 设备是将虚拟经营世界与真实世界相融的必 要设备。

6. 元宇宙是什么梗

指沉浸式的虚拟世界,英文Metaverse。这个虚拟世界由VR(虚拟现实)、AR(增强现实)等3D技术和互联网组成。用户可以在元宇宙中感受不一样的人生,或是体验与真实世界完全不同的世界。与现有网络游戏不同的是,元宇宙能给玩家带来更真实的感受,让玩家可以仿佛置身于虚拟世界当中,甚至可以做到无法区分真实与虚拟世界。元宇宙也被吹捧成了互联网的终极形态。 电影《黑客帝国》和《头号玩家》就是元宇宙概念。 元宇宙一词最早出自美国科幻小说《雪崩》。小说中描绘了一个与现实世界平行的虚拟世界,元界(Metaverse)。

7. 迅速蹿红的“元宇宙”,到底是“风口”还是“虎口”

是风口三,元宇宙现在的已经运用的技术,已经说明是一个风口,并且是一个大风口。在过去时间里,我国已经研制出虚拟的人物,这其中就包括2021年6月1日,清华大学计算机系知识工程实验室迎来了中国首个原创虚拟学生——华智冰,清华大学为她办理了学生证和邮箱。 而华智冰的出现也代表着元宇宙在我国有着新的纪元。通过大数据以及各项数据判断,元宇宙的应用越来越广泛,这种广泛也必然是一个趋势一个方向,所以也一定是个风口。

四,过去的风口完全可以预判到元宇宙的未来。简单来说在工业革命前夕,蒸汽机发明以及新大陆的发现都给第一次工业革命带来了一个风口。那么现在虚拟技术的发展,AR技术的成熟,也给元宇宙带来技术支持的基础,这种基础也必然会给一个风口明显的导向。

8. 元宇宙游戏毁了多少孩子

大家好,我是很帅的狐狸

今天我准备来聊聊

元宇宙

最近这个概念很火——

facebook改名Meta迎接元宇宙,抖音的元宇宙up主「柳夜熙」凭借两个视频收获了200万粉丝,甚至罗永浩老师都提到了,自己下一个创业项目将会是元宇宙……


那么问题就来了——


元宇宙到底是什么?

后续它会怎么发展?最终形态是怎样的?

为什么说目前元宇宙最大的风险是政策风险?

为什么我们说它有可能会毁了这个世界?

我们有办法避免它对人类的摧毁吗?

这篇文章会回答上面的这些问题,希望可以升级你对世界的认知,辅助你更好地预测人类社会的发展趋势,找到在后续每个阶段最关键的技术与应用。

先来看看第一个问题:元宇宙是什么?

「元宇宙」这个概念来自科幻小说《雪崩》,简单来说就是一个虚拟世界。

在这个世界里头,用户可以连接万物,并且可以做到很多物理世界里无法实现的操作。

在科幻作品里头,元宇宙会更丰富一些: 比如像《头号玩家》里头那样,使用VR眼镜来与其他个体互动——

不过,元宇宙并不会单单停留在「炒作」层面上,它有极强的可拓展性。

未来的元宇宙,可能是像电影《超能查派》或《超验骇客》一样,我们可以把自己的意识上传到网络上,到时我们可以脱离肉身完全生活在元宇宙里。

大家听到这么赛博朋克的概念通常会特别兴奋,但我想把大家稍微往现实拉回来一些:

因为再往后推演了几步后我们发现,等发展到第4阶段,元宇宙很可能会让人类固步自封,甚至有可能毁了这个世界。

接下来我们可以一起来看看后续元宇宙的发展推演。

目前看来,我们还处于第一阶段——

阶段 1

虚拟元宇宙 ️

元宇宙其实是在复刻人类在现实世界的感官感受。

最早因为设备的限制 (只有电脑和手机) ,所以我们只能复刻一部分视觉和听觉的体验。

像是我以前详细介绍过的游戏 ,在那个元宇宙里一切皆有可能:玩家可以开银行、炒地皮、开会……这个游戏甚至还成功地预言了2008年的金融危机,感兴趣的可以翻看我之前的文章。

德国华人玩家Chung Anshe在现实生活中是个老师,在游戏中却靠着炒卖地皮赚了上百万美金,其虚拟形象甚至登上了《财富》和《商业周刊》杂志的封面。

图/商业周刊

还有后来流行的Roblox、我的世界、摩尔庄园、动森等等……

就像前面说的,所有角色扮演类游戏都可以说是「元宇宙」的前身。

而这几年,技术的发展让我们可以更好地复刻现实世界的体验——


基于上面提到的这些技术,我们可以更快地接收、处理、传输、输出感官信息。

我们来重点说一下负责信息输出的VR终端,它们的作用是复刻五感的体验——

目前我们对视觉和听觉的模拟已经相对成熟了。

触觉方面,目前有类似《头号玩家》里头的全身触觉体验套件Teslasuit,可以通过电流刺激来模拟触觉。

图/Teslasuit

嗅觉方面,有个叫OhRoma的产品可以模拟战争中的硝烟味、僵尸扑过来时的腐烂味、女生靠近时的体香 (其实…这个产品是色情网站设计的) 等等。

图/Techcrunch

随着化学和材料学等学科的发展,理论上未来也可以合成相应的气体固体,模拟更多嗅觉体验,甚至味觉。

到时候,我们会进入一个几乎可以复原现实世界一切感官体验的元宇宙。

不过,毕竟一切只是「模拟」,还是很难完美复刻所有感官体验。

这时候,我们会尝试进入「阶段2」。

阶段 2

脑接元宇宙

之前我在科普 的时候就提到过「缸中之脑」实验。

人类的感受其实都是大脑的「骗局」:而既然大脑信号都是电信号,我们完全可以把大脑信号转化为计算机可以读懂的语言,反过来也可以把计算机信号转化为大脑可以感知的电信号。

这样我们靠一段代码,就可以模拟吃饭的感受。

像是马斯克这几年在研究的脑机接口技术,就在努力攻克这些课题。

图/Neuralink

随着技术发展,未来我们或许完全不需要通过VR眼镜等外接设备,也可以直接通过电信号完美复刻现实世界带来的感官体验。

不过呢,还是有问题存在:我们的吃喝拉撒还是得在现实世界完成,人类无法跟现实世界完全脱节。

一种解决方案是类似电影《黑客帝国》的场景:所有人类的肉体被妥善保存,通过营养液维持生命机能——

图/《黑客帝国》剧照

这背后也有「两颗药丸」的伦理问题:「真实」到底重不重要?

Anyway,即使伦理问题解决了,所有人都愿意选择在元宇宙里生活和工作了,仍然有问题无法解决:衰老与死亡。

这时候,人类会尝试进入下一个阶段的元宇宙——

阶段 3

意识元宇宙

随着全脑仿真技术与人工智能技术的发展,未来如果我们可以像《超能查派》或《超验骇客》一样,直接把人类意识上载到服务器上,同时让意识具备自我计算机能,那么我们可以脱离肉身完全活在元宇宙里,彻底地进化为硅基生物。

而且我们的意识还可以无限复制,传到全世界的各个服务器上。

这个哲学上的讨论很多,今天就不展开了。

感兴趣的话,可以去看看WaitButWhy的文章《What Makes You You?》。

Anyway,假设意识本身都是「我」,那么在意识可以备份的前提下,只要不存在全球性灾难事件引发全网断网、数据库全毁这样的极端情形,理论上我们都可以实现「永生」。

不过这时候还是有问题:人们会变得不再快乐。

这一点可能有点违反直觉,我来解释解释——

大家之所以喜欢元宇宙的概念,是因为它能摆脱现实世界的诸多限制。

比如空间限制,我们可以在元宇宙里实现瞬间移动。

我们也可以脱离时间限制,很多动作可以有即时反馈,压根都不需要等待。

如果我们的意识可以上传到元宇宙,我们甚至可以通过提高计算速度,来改变我们对时间流逝的感知——就像刘慈欣在长篇处女作《中国2185》里头所描述的,「虚拟人类」在两个小时里度过了600年的演化。

还有就是规律限制——在元宇宙里我们能做到很多违背物理学生物学规律的事情,比如你可以飞可以漂浮,就算被车撞了被剑刺了也不会真正意义上的「死亡」。

图/Mark Zuckerberg via FB

而更重要的,在元宇宙里,理论上你也没有资源限制——

你可以拥有无限多的资源,你可以拥有无数套房、无数辆豪车、无数个名牌包包……

只要计算资源允许,甚至每个人都可以拥有自己的元宇宙,成为自己宇宙的「神」。

那么问题就来了——

既然几乎没有限制,为啥还会「不再快乐」呢?

这是因为,快乐的来源,在于「预期差」。

几乎什么都做得到,要什么就有什么,你就不会有「求之而不得」的感觉。

就算你得到了一切,都会觉得这是理所当然的。

而且意识被上载还有一个后果:我们的计算速度和准确性变强了,出现「意外」的概率很小。

换句话说,我们的「预期」变得极其准确,这也是导致没有预期差的原因。

意识到这一点的人会开始进入下一个阶段——

阶段 4

孪生元宇宙

为了制造预期差,我们会开始某种程度的自我设限,复刻真实世界中的各种规律:物理学、经济学…创造出一个现实世界的镜像,也就是我们经常会听到的「数字孪生」。

最简单的做法是加入随机数。

就像玩游戏抽道具,把把欧皇并不会让人沉迷,有了随机变量自然会有意外,会有预期差。

当然,我们也可以自我设限,让资源不再无限 (不过这也失去了元宇宙的大部分魅力) 。

比如说,我们可以利用我以前科普过的 ,让元宇宙里头的虚拟物品具备稀缺属性。

这么做,本质上就是让资源不再可以随随便便地无限复制,那么现实世界中的经济规律也可以在元宇宙里头被复刻。

当然,这些手段其实在更早的阶段就会开始发生,像是NFT在这几年就被热炒过几波。

不过在这个阶段还是有两个致命的问题,这两个问题甚至有可能让人类不再拥有创造力。

第一个问题是时间资源无法受限。

上载意识后,人类实现了「永生」。

虽然我们会自我设限,让经济规律重现,但我们不大可能会让时间资源被压缩。

毕竟从伦理道德来看,剥夺一个人的剩余时间,相当于主动「杀死」他。

一旦人类拥有近乎无限的生命,他们会做什么?

奈飞《爱死机》第二季的《Pop Squad》 (人口警察) 给出了答案——人类将会丧失创新意愿。

剧集里的一个女性角色,她是个歌手,过去20年一直在磨炼某一段独唱。

图/爱死机2

因为她拥有了无限的时间,已经试错了足够多次,「从0到1」甚至「从1到100」都搭好了,所以会把更多的精力放在「从100到101」的层面。

顺带一提,这时候「繁衍后代」也会变得没那么重要,你甚至可以跟NPC (人工智能) 生下后代,但很可能只是为了体验当父母的乐趣。

Anyway,人类创新的步伐确实会因此放缓。

当然你也可以说,虽然是放缓,但还是在进步的;而且时间资源近乎无限,那长远来看,人类还是在发展的。

这时候我们还会面对另一个问题——信息茧房。

人类知识的发展,要有信息的输入才能有智慧的输出。

而在元宇宙里头,信息的输入源会被局限在元宇宙 (外加地球) 本身,这会限制人类知识边界的拓展,会形成一个信息茧房。

当然,自我演化本身也可以有输出:因为我们对原始数据的处理会得到新的信息,会产生新的认知与洞见。

但这些都只是人类自身活动而产生的信息。

更可怕的是,一旦算力足够多,每个人都可以在意识里加载所有人类已知的知识,那么每个个体的输入相同、处理机制也相同 (因为处理机制由输入的信息决定) ,这样每个个体的输出也会相同。

这会诞生很多科幻小说里提到的「统一意识体」。

多样性的美将不复存在。

那么问题来了——如何破局呢?

人类在彻底理解了元宇宙与地球之后,还是有拓展知识边界的需求的。

这时候,我们需要打破信息茧房,从地球外部去找输入。

就像我在新加坡的ArtScience Musuem (艺术科学博物馆) 里头看到的这么一句话——

图/狐狸

翻译过来就是「科学是宇宙想告知人类的,而艺术则是人类想告知宇宙的。」

所以过往一直有所谓「飞船派」和「元宇宙派」的争论——

到底人类的未来,是走向外星殖民?还是成为地下运转的服务器?

如果是后者,那么一个流星过来,人类很可能会就此湮灭。

这是包括刘慈欣老师在内的诸多科幻小说家、未来学家所担心的;也是我开头提到的「元宇宙可能会毁掉这个世界」的底层逻辑。

无独有偶,人类登月的第二人Buzz Aldrin也吐槽过:「你承诺过给我们火星殖民,现在我得到的却只有Facebook。」

图/麻省理工科技评论

那么问题就来了——

你到底会选择加入「飞船派」呢?还是「元宇宙派」呢?

最后我想说,这两个派别其实并不矛盾。

这就像是投资和消费的关系一样。

像费雪说的,「投资是时间维度上的平衡消费」,或者说,投资其实就是未来的消费。

一样的,「飞船派」是在拓宽信息源,而「元宇宙派」则是在更好地利用和处理现有的信息。

两者并不矛盾,可以两者兼有。

只是,我们不能把所有的钱都花在消费上,还是该拿出一部分来投资。

照例一张图总结一下——

P.S.总有一天,疫情终将过去。疫情前和疫情后的生活会有什么变化,后疫情时代又有什么投资机会呢?找天给大家聊聊不晓得你们会感兴趣不,感兴趣的小伙伴点个在看呗。

9. “元宇宙”火了,这玩意到底是啥

元宇宙(Metaverse)是利用科技手段进行链接与创造的,与现实世界映射与交互的虚拟世界,具备新型社会体系的数字生活空间。[12]
元宇宙本质上是对现实世界的虚拟化、数字化过程,需要对内容生产、经济系统、用户体验以及实体世界内容等进行大量改造。但元宇宙的发展是循序渐进的,是在共享的基础设施、标准及协议的支撑下,由众多工具、平台不断融合、进化而最终成形。[23]它基于扩展现实技术提供沉浸式体验,基于数字孪生技术生成现实世界的镜像,基于区块链技术搭建经济体系,将虚拟世界与现实世界在经济系统、社交系统、身份系统上密切融合,并且允许每个用户进行内容生产和世界编辑。[23]
元宇宙一词诞生于1992年的科幻小说《雪崩》,小说描绘了一个庞大的虚拟现实世界,在这里,人们用数字化身来控制,并相互竞争以提高自己的地位,到现在看来,描述的还是超前的未来世界。[1]关于“元宇宙”,比较认可的思想源头是美国数学家和计算机专家弗诺·文奇教授,在其1981年出版的小说《真名实姓》中,创造性地构思了一个通过脑机接口进入并获得感官体验的虚拟世界。


1. I have thought about many postgraduate entrance examination issues and don’t know what to do.

First of all, consider your own academic problems, pay attention to your own learning status and ideas, and decide what you want to do in the future. That’s it, the postgraduate entrance examination is just a way out in the future

2. What exactly is the Metaverse Convention and Exhibition, and will it give birth to the next "New World of Convention and Exhibition"

Life can actually be A poem: If you can let me move forward slowly, quietly looking forward to searching, with the deepening twilight, passing through the unknown mud, in the dark clouds, I finally shed tears for all

3. Metaverse What exactly does the concept mean

Metaverse refers to entering a virtual space through VR or AR equipment, and then people can freely socialize, work, or do other things in this virtual space. some things. The Metaverse concept mainly refers to some Metaverse-related concept stocks in the stock market. Because the market has been enthusiastically hyping these concepts recently. However, there are also some voices who are opposed to the development of the Metaverse. They believe that the Metaverse will lead people astray.

1. Metaverse

I don’t know if you have seen a movie called "Ready Player One". The wish that the metaverse wants to realize is a situation similar to this movie. People can enter a virtual world through head-mounted AR or VR equipment, which is also called the Metaverse. In this world, everything has value, and certification can be achieved through blockchain technology. Just like some celebrities some time ago, they spent millions or even tens of millions of dollars to buy an NFT avatar, which is an asset of the Metaverse.

After everyone has finished reading, remember to like + follow + collect.

4. Tsinghua University released the latest research results of Tsinghua University. How important is this result?

This time the results basically promote the development of related industries and have the latest technology. .

5. Discuss the business model of using real-sense imaging technologies such as VR/AR/XR to realize the Metaverse platform

Abstract The development of the Metaverse can be divided into four stages. Currently, it is in the PC-based , the mobile terminal is the quasi-metaverse stage of the interface. In a narrow sense, Metaverse is a next-generation Internet ecosystem built around the three major technologies of XR, AI, and blockchain. Among them, XR technology (VR/AR/MR/brain-computer interface, etc.) is the key technology to achieve immersion. XR equipment is necessary to integrate the virtual business world with the real world.

6. What is the metaverse?

Refers to the immersive virtual world, the English Metaverse. This virtual world is composed of 3D technologies such as VR (Virtual Reality), AR (Augmented Reality) and the Internet. Users can experience a different life in the metaverse, or experience a world completely different from the real world. Different from existing online games, MetaverseIt can bring players a more realistic feeling, allowing players to feel as if they are in a virtual world, and even make it impossible to distinguish between the real and virtual worlds. The Metaverse has also been touted as the ultimate form of the Internet. The movies "The Matrix" and "Ready Player One" are concepts of the Metaverse. The term metaverse first came from the American science fiction novel "Snow Crash". The novel depicts a virtual world parallel to the real world, the Metaverse.

7. Is the rapidly becoming popular "Metaverse" a "wind outlet" or a "tiger's mouth"

It is the third outlet. The technology currently used in the Metaverse has shown that it is a The wind outlet is a big one. In the past time, our country has developed virtual characters, including On June 1, 2021, the Knowledge Engineering Laboratory of the Department of Computer Science of Tsinghua University welcomed China's first original virtual student-Hua Zhibing. She applied for her student ID card and email address. The emergence of Hua Zhibing also represents a new era for the Metaverse in our country. Judging from big data and various data, the application of the metaverse is becoming more and more extensive. This wideness must be a trend and direction, so it must also be an outlet.

Fourth, past trends can completely predict the future of the Metaverse. To put it simply, on the eve of the Industrial Revolution, the invention of the steam engine and the discovery of the New World brought an outlet to the first Industrial Revolution. So the current development of virtual technology and the maturity of AR technology have also brought a foundation of technical support to the Metaverse. This foundation will inevitably give a clear direction for the trend.

8. How many children have been ruined by metaverse games

Hello everyone, I am a very handsome fox

I am going to talk today

< p>Metaverse

This concept is very popular recently -

Facebook changed its name to Meta to welcome the Metaverse, and Douyin’s Metaverse up master "Liu Yexi" gained a lot of money with two videos 2 million fans, and even teacher Luo Yonghao mentioned that his next entrepreneurial project will be the Yuanverse...


Then the question arises——


What exactly is the Metaverse?

How will it develop in the future? What is the final form?

Why is it said that the biggest risk in the Metaverse at present is policy risk?

Why do we say it might destroy the world?

Is there any way to avoid its destruction of humanity?

This article will answer the above questions. I hope it can upgrade your understanding of the world, help you better predict the development trends of human society, and find the best solutions for each subsequent stage. Key technologies and applications.

Let’s take a look at the first question: What is the Metaverse?

The concept of "Metaverse" comes from the science fiction novel "Snow Crash". Simply put, it is a virtual world.

In this world, users can connect everything and perform many operations that are impossible in the physical world.

In science fiction works, the metaverse will be richer: for example, like in "Ready Player One", VR glasses are used to interact with other individuals -

However, the metaverse is not It will not just stay at the "hype" level, it has strong scalability.

The metaverse of the future may be like the movie "Chappie" or "Transcendence". We can upload our consciousness to the Internet, and then we can live completely without the physical body. In the metaverse.

Everyone is usually very excited when hearing such a cyberpunk concept, but I want to bring everyone back to reality a little bit:

Because after a few steps of deduction, we It was found that when it reaches the fourth stage of development, the Metaverse is likely to make humans stagnate and even destroy the world.

Next we can take a look at the subsequent development of the Metaverse.

Currently, it seems that we are still in the first stage -

Phase 1

Virtual Metaverse️

The Metaverse is actually Replicating human sensory experiences in the real world.

At first, due to device limitations (only computers and mobile phones), we could only reproduce part of the visual and auditory experience.

Like the game I have introduced in detail before, everything is possible in that metaverse: players can open a bank, speculate in land, hold meetings... This game even successfully predicted the financial future in 2008. Crisis, if you are interested, you can read my previous articles.

Chung Anshe, a Chinese-German player, is a teacher in real life, but has made millions of dollars by speculating on real estate in the game. His avatar has even appeared in Fortune and Business Week. Magazine cover.

Picture/Business Weekly

There are also the later popular Roblox, Minecraft, Moore Manor, Animal Crossing, etc...

As mentioned before , all role-playing games can be said to be the predecessor of the "Metaverse".

In recent years, the development of technology has allowed us to better replicate the real-world experience——


Based on the technologies mentioned above, we can Receive, process, transmit, and output sensory information faster.

Let’s focus on the VR terminals responsible for information output. Their role is to reproduce the experience of the five senses——

At present, our simulation of vision and hearing has Relatively mature.

In terms of tactile sensation, there is currently a full-body tactile experience suite, Teslasuit, similar to that in "Ready Player One", which can simulate touch through electrical stimulation.

Picture/Teslasuit

In terms of smell, there is a product called OhRoma that can simulate warThe smell of gunpowder smoke, the smell of decay when zombies attack, the body scent of girls when they get close (actually... this product is designed by pornographic websites), etc.

Picture/Techcrunch

With the development of disciplines such as chemistry and materials science, it is theoretically possible to synthesize corresponding gaseous solids in the future to simulate more olfactory experiences and even taste.

At that time, we will enter a metaverse that can restore almost all sensory experiences in the real world.

However, after all, everything is just a "simulation", and it is still difficult to perfectly reproduce all sensory experiences.

At this time, we will try to enter "Phase 2".

Phase 2

Brain Connected to the Metaverse

I have mentioned the "brain in a vat" experiment before when I popularized science.

Human feelings are actually "deceptions" of the brain: and since brain signals are all electrical signals, we can completely convert brain signals into a language that computers can understand, and conversely, we can also convert computer signals into Converted into electrical signals that the brain can perceive.

In this way, we can simulate the feeling of eating with a piece of code.

For example, the brain-computer interface technology that Musk has been researching in recent years is working hard to overcome these issues.

Picture/Neuralink

With the development of technology, in the future we may not need to use external devices such as VR glasses at all, but can also perfectly reproduce the senses brought by the real world directly through electrical signals. experience.

However, there is still a problem: our eating, drinking, and diarrhea still have to be completed in the real world, and humans cannot be completely disconnected from the real world.

One solution is a scene similar to the movie "The Matrix": all human flesh is properly preserved and life functions are maintained through nutrient solution -

Picture/"The Matrix" Stills

There is also the ethical issue of "two pills" behind this: Is "truth" important?

Anyway, even if the ethical issues are solved and everyone is willing to choose to live and work in the metaverse, there are still problems that cannot be solved: aging and death.

At this time, humans will try to enter the next stage of the metaverse -

Phase 3

The metaverse of consciousness

As With the development of whole-brain simulation technology and artificial intelligence technology, in the future, if we can directly upload human consciousness to the server like "Chappie" or "Transcendental Hack", and at the same time allow consciousness to have self-computing capabilities, then we Can leave the physical body and live completely in the metaverse, completely evolving into a silicon-based creature.

And our consciousness can be copied infinitely and spread to various servers around the world.

There are many philosophical discussions, so I won’t go into them today.

If you are interested, you can read WaitButWhy’s article "What Makes You You?".

Anyway, assuming that consciousness itself is "I", then on the premise that consciousness can be backed up, as long as there is no extreme situation such as a global disaster event causing the entire network to be disconnected and the database to be completely destroyed, in theory we can all "Eternal life" can be achieved.

But there is still a problem: people will no longer be happy.

This may be a bit counterintuitive, let me explain -

The reason why everyone likes the concept of the metaverse is that it can get rid of many restrictions of the real world.

For example, due to space limitations, we can achieve instant movement in the metaverse.

We can also get rid of the time limit. Many actions can have immediate feedback, without waiting at all.

If our consciousness can be uploaded to the metaverse, we can even change our perception of the passage of time by increasing the calculation speed - just as Liu Cixin described in her debut novel "China 2185", "Virtual humans" spent 600 years of evolution in two hours.

There are also law restrictions - in the metaverse we can do many things that violate the laws of physics and biology. For example, you can fly or float, even if you are hit by a car or stabbed with a sword, you will not be able to do anything. Will "die" in the true sense.

Picture/Mark Zuckerberg via FB

And more importantly, in the metaverse, theoretically you have no resource limits -

You can have unlimited With so many resources, you can have countless suites, countless luxury cars, countless brand-name bags...

As long as the computing resources allow, everyone can even have their own metaverse and become the "" of their own universe" god".

Then the question comes -

Since there are almost no restrictions, why is it "no longer happy"?

This is because the source of happiness lies in the "expectation difference".

You can do almost anything, you can get whatever you want, and you won’t have the feeling of “not getting what you want.”

Even if you get everything, you will take it for granted.

And there is another consequence of uploading consciousness: our calculation speed and accuracy have become stronger, and the probability of "accidents" is very small.

In other words, our "expectations" have become extremely accurate, which is also the reason why there is no expectation difference.

People who realize this will begin to enter the next stage -

Phase 4

Twin Metaverse

In order to create expectations Otherwise, we will begin to set limits on ourselves to a certain extent, replicating various laws in the real world: physics, economics... to create a mirror image of the real world, which is the "digital twin" that we often hear.

The simplest way is to add random numbers.

Just like playing a game to draw props, playing European Emperor will not make people addicted. With random variables, there will naturally be accidents.Poor expectations.

Of course, we can also set limits on ourselves so that resources are no longer unlimited (but this also loses most of the charm of the metaverse).

For example, we can use what I have popularized before to make the virtual items in the metaverse have scarcity attributes.

This essentially means that resources can no longer be copied casually and infinitely, so that the economic laws in the real world can also be replicated in the metaverse.

Of course, these methods will actually start to happen at an earlier stage. For example, NFT has been hyped several times in recent years.

However, there are still two fatal problems at this stage, which may even make humans no longer creative.

The first problem is that time resources cannot be limited.

After uploading consciousness, human beings have achieved "eternal life".

Although we will set limits on ourselves to allow economic laws to reappear, we are unlikely to allow time resources to be compressed.

After all, from an ethical point of view, depriving a person of his remaining time is equivalent to actively "killing" him.

What will humans do once they have near-infinite life?

"Pop Squad" (Population Police) in the second season of Netflix's "Love to Death" gives the answer-human beings will lose their will to innovate.

There is a female character in the series. She is a singer and has been practicing a certain solo for the past 20 years.

Picture/Love Death Machine 2

Because she has unlimited time and has tried and failed enough times, "from 0 to 1" or even "from 1 to 100" works. Okay, so I will focus more on the "from 100 to 101" level.

By the way, "reproducing offspring" will become less important at this time. You can even have offspring with NPC (artificial intelligence), but it is probably just to experience the fun of being a parent.

Anyway, the pace of human innovation will indeed slow down.

Of course, you can also say that although it is slowing down, it is still progressing; and time resources are almost unlimited, so in the long run, human beings are still developing.

At this time we will also face another problem - information cocoon room.

The development of human knowledge requires the input of information to produce the output of wisdom.

In the metaverse, the input source of information will be limited to the metaverse (plus the earth) itself, which will limit the expansion of the boundaries of human knowledge and form an information cocoon.

Of course, self-evolution itself can also have output: because our processing of original data will obtain new information and generate new cognitions and insights.

But these are only information generated by human activities.

What’s even more frightening is that once there is enough computing power, everyone can load all known human knowledge into their consciousness. Then each individual’s input will be the same and the processing mechanism will be the same.The same (because the processing mechanism is determined by the input information), so the output of each individual will be the same.

This will give birth to the "unified consciousness" mentioned in many science fiction novels.

The beauty of diversity will no longer exist.

Then the question is - how to break the situation?

After humans thoroughly understand the metaverse and the earth, they still have a need to expand the boundaries of knowledge.

At this time, we need to break the information cocoon and find input from outside the earth.

Just like this sentence I saw in the ArtScience Musuem (ArtScience Museum) in Singapore——

The translation is "Science is what the universe wants to tell humans, while art is what humans want to tell the universe."

So there has been a debate between the so-called "spaceship faction" and the "metaverse faction" in the past——< /p>

In the end, is the future of mankind heading toward alien colonization? Or will it become a server operating underground?

If it is the latter, then if a meteor comes over, human beings will probably be annihilated.

This is what many science fiction novelists and futurists, including Mr. Liu Cixin, are worried about; it is also the underlying logic of the "metaverse may destroy the world" I mentioned at the beginning.

Coincidentally, Buzz Aldrin, the second man to land on the moon, also complained: "You promised to colonize Mars for us, but now all I get is Facebook."

Then the question comes -

Would you choose to join the "Spaceship Faction"? Or is it the "Metaverse Sect"?

Finally, I want to say that these two factions are not actually contradictory.

This is like the relationship between investment and consumption.

As Fisher said, "Investment is balanced consumption in the time dimension." In other words, investment is actually future consumption.

Similarly, the "Spaceship Faction" is broadening the sources of information, while the "Metaverse Faction" is making better use of and processing existing information.

The two are not contradictory and can be both.

It’s just that we can’t spend all our money on consumption, we should still invest part of it.

As usual, I will summarize it with a picture——

P.S. One day, the epidemic will eventually pass. How will life change before and after the epidemic? What investment opportunities will there be in the post-epidemic era? I want to chat with you someday. I don’t know if you will be interested. If you are interested, please click and watch.

9. "Metaverse" is popular, what is this thing?

Metaverse is linked and created using scientific and technological means, and it maps and interacts with the real world. Virtual world, a digital living space with a new social system. [12]
The Metaverse is essentially a virtualization and digitalization process of the real world, which requires a lot of transformation of content production, economic systems, user experience, and physical world content. However, the development of the Metaverse is gradual. It is finally formed by the continuous integration and evolution of many tools and platforms under the support of shared infrastructure, standards and protocols. [23] It provides an immersive experience based on extended reality technology, generates a mirror of the real world based on digital twin technology, builds an economic system based on blockchain technology, and closely integrates the virtual world and the real world in the economic system, social system, and identity system. , and allows each user to perform content production and world editing. [23]
The term metaverse was born in the 1992 science fiction novel "Snow Crash". The novel depicts a huge virtual reality world where people use digital avatars to control and compete with each other to improve their status. , so far it seems that it still describes an advanced future world. [1] Regarding the "metaverse", the more recognized source of thought is the American mathematician and computer expert Professor Verno Vinci. In his novel "Real Names" published in 1981, he creatively conceived a brain-computer system. Interface to enter and gain sensory experience in the virtual world.
