Original title: meta universe: or redefining human civilization 4.0

You may not be interested in the topic of metauniverse, but you can't be interested in the future of mankind! If the future is bound to happen, enter that future first.

In 2021, the yuan universe came, the market attention was high, the industry coverage was wide, the discussion was popular, and the hot time was long. It was afraid that it would be difficult to catch up with them. Of course, the confrontation between differences and consensus was also rampant. Therefore, it is not too much to call this year the "first year of the meta universe".

To make a joke, the reason why the "meta universe" is out of the circle is definitely related to the creativity of writers and translators. Metaverse is "metaverse" in English. It was created by science fiction writer Neil Stephenson in 1992. The prefix meta means transcendence. The root word verse evolved from universe and generally refers to the universe and the world. Whether it's prefix or root, it's made of special art! In other words, if it is called "super world", does it mean almost? And when translated into "super world" and "more universe", is it not as cool as "meta universe"? Therefore, there will be a phenomenon that the word can be so profound that everyone does not understand it, and can be popularized to everyone to discuss it.

Therefore, in the past six months, research institutions, news media, brokerage funds, forum lectures and so on have carried out the most extensive literacy education around the meta universe, emerging in endlessly. But today, the author wants to understand the meta universe from the perspective of human historical development, and explore the value of the meta universe to human beings from the conceptual rather than technical level.

๏ผˆ1๏ผ‰ Metauniverse: digital version of parallel universe

In a brief history of mankind, Yuval herali puts forward a subversive view: the fundamental driving force behind human history lies in the cognitive revolution driven by imagination. In short, imagination is the underlying driving force of human progress. After reviewing human history, the author further finds another law: human's ability to realize imagination is beyond imagination. In other words, in the history of human progress, there is nothing that cannot be done, only unimaginable; If you can't do it, you can do it in another form!

A well-known example is that when Wu Chengen wrote journey to the west 500 years ago, he imagined that all kinds of gods and ghosts could fly through the clouds, but he certainly wouldn't think that people in the future could really "fly", just fly in the clouds by plane, and the flight experience was much better than Qi Tiansheng's naked flight.

There are many film and television works about the parallel universe, such as the night of the comet, the mirage and so on. The key "stem" in the film is that the protagonist has a separate body in multiple parallel universes, and each separate body is equal to each other with equal weight. Of course, the switching between different parallel universes is often an accident, such as the emergence of comets, storms and so on. However, such a plot is only the imagination of the screenwriter or creator. Is there really a parallel universe? At least for now, there is no obvious evidence of the existence of a parallel universe! If there is no objective existence, but the parallel universe is imagined by human beings, will the parallel universe be realized according to the above law? Yes, to put it another way, that is, the meta universe: the digital version of the parallel universe. And those parallel separations are not the so-called digital separations?

๏ผˆ2๏ผ‰ Meta universe: Super virtual world = highly intelligent real world ร— Highly intelligent virtual world

In other words, there are different definitions of the meta universe. A thousand people can really have a thousand interpretations. This is because the meta universe "is still a developing and evolving concept, and different participants continue to enrich its meaning in their own ways." We might as well repeat the views of two scholars from Tsinghua University and Peking University. Shenyang professor of Tsinghua University defines: "the meta universe is a new Internet application and social form integrating virtual reality produced by integrating a variety of new technologies." Professor Chen Gang of Peking University defined: "the meta universe is a virtual world linked and created by scientific and technological means, mapped and interacted with the real world, and a digital living space with a new social system." To some extent, the definitions of Professor Shen and Professor Chen accurately reveal the connotation of the meta universe.

One of the puzzles of the concept of meta universe itself is that it is too abstract. Can we simply and popularly define the meta universe in one sentence? The author's definition is that the meta universe is "super virtual world - a highly intelligent virtual world coupled with the real world in the future"! What is super? Super means highly intelligent and highly coupled with the real world in the future. The central word of this definition is "virtual world", but this "virtual world" is not the other "virtual world". The "virtual world" referred to by the meta universe means digital space, not utopian world. It can be seen that the definition has at least three levels of meaning: 1. High intelligence; 2. Highly coupled with the real world; 3. Digital space.

In the past, the virtual world was more a concrete imaginary world, without the extension, mapping, reproduction and coupling of the real world. It was just a fantasy in people's brain and did not have the subject identity. We can call it the original virtual world. It is independent of the real world and has a very loose relationship with it. Movies and games are typical virtual worlds, but in these scenes, it is difficult for viewers or players to obtain or experience the perception in the real world in the first person. This is one of the purposes for people to constantly explore VR, AR, Mr and other extended reality technologies.

However, the connotation and extension of the virtual world, which is highly intelligent and highly coupled with the real world, will change significantly in the future. It is a highly intelligent digital space that is closely coupled and integrated with the real world physically. This is reflected in at least three important aspects: first, the virtual world itself makes itself more intelligent with the help of artificial intelligence technologies such as machine learning, and even has the so-called "digital vitality" (there are such passages in the films transcendental hacker and eagle eye). Second, the virtual world establishes a connection with the real world and people through sensing materials and equipment, expanding reality, brain computer interface and other technologies, so that people's perception and touch can shuttle between the two worlds (the plot described in the movies hacker empire and number one player). Third, the virtual world realizes the right confirmation of digital assets through blockchain and NFT technology, so as to establish a secure digital economic system.

Finally, the real world and the virtual world are closely integrated, virtual and real symbiosis, and the virtual world becomes a part of the subject from the object, which will form a symbiotic subject coupled by the "real world" and "virtual world": meta universe = Super virtual world = highly intelligent real world ร— Highly intelligent virtual world. Of course, we can also understand the "highly intelligent virtual world" as a narrow meta universe.

In order to better understand the meaning of the virtual world and avoid confusion, we can look at it from the perspective of language. "Virtual world" is exactly a popular expression, or common name, and its academic name is "digital world". Correspondingly, the scientific name of "real world" is "physical world". "Atomic world" also refers to the real world, "bit world" refers to the virtual world. "Digital space", as well as "digital new world", "digital Utopia" and so on, are synonyms used to describe the virtual world.

In a word, just like a word that has not been emphasized in the title of this section: the future - metauniverse is the best gift that futurists give to the human world in 2021.

๏ผˆ3๏ผ‰ Meta universe: the integrated application of the sum of digital technology = a new species jointly constructed by the digital technology group

At present, there is a popular view that metauniverse is in the same line with PC Internet (first generation Internet) and mobile Internet (Second Generation Internet), which is "next generation Internet" or "Web3.0". Although this may be an analogy for understanding the meta universe, the author believes that this formulation pattern may be slightly lower, ha ha! Why?

Metauniverse is the next generation of Internet applications. It is very limited and thin in semantics and context! Because the meta universe is a comprehensive application of the sum of many digital technologies, such as artificial intelligence, big data, cloud computing, edge computing, 5g, extended reality, blockchain, quantum technology, cloud side-to-side collaboration, digital twinning, data center and so on, using the Internet alone can not represent such a complex group of digital technologies.

In addition, the expression of "next generation Internet" still focuses on "Internet", which means that the meta universe is the extension, development and evolution of the Internet, but what the connotation of the meta universe wants to express is that the meta universe itself is its own subject. It is a new species that connects a large number of discrete single point digital technologies developed in the past few decades into a line and then converges to a surface. Here, all digital technologies are given new life. For example, make data an asset through blockchain, build a programmable intelligent economic system through smart contract, build a global intelligent brain and create "digital people" through artificial intelligence, and widely map the real objects of the physical world to the digital space through the Internet of things, Realize the integration of digital world and physical world by expanding reality technology, and so on.

The past few decades can be said to be the golden age of the technology explosion. Countless advanced technologies have been invented and created and widely benefit mankind. For example, the following ABCDEFG

Artificial intelligence

Block chain: blockchain

Cloud Computing: Cloud Computing

Data technology: big data technology

Edge computing: edge computing

Fifth generation mobile communication technology

Graphics processing: graphics processing

Internet of things

Quantum computing: quantum computing

Digital twins: Digital twins

XR (augmented reality, virtual reality, mixed reality): expanding reality technology


You can keep it in alphabetical order if you like.

But have you found out that they actually have a common name: digital technology. Encyclopedia definition: digital technology is a science and technology accompanied by electronic computers. It refers to the technology of computing, processing, storage, transmission, dissemination and restoration after converting various information, including pictures, texts, sounds and images, into binary numbers "0" and "1" recognized by electronic computers with the help of certain equipment.

The emergence of each new digital technology will give birth to new species, new businesses and new models, so as to drive the progress of mankind.

Artificial intelligence: from smart phones and speakers to smart wear and smart cars, AI has gradually become the "key to success" for thousands of industries. The integration of AI has brought many changes to industrial manufacturing, public utilities, finance, retail, education, health care, agriculture and other industries.

Blockchain: a few years ago, the noise of ICO was just a small tributary of blockchain exploration. Blockchain has become a subversive technology to promote many industrial changes, and began to be rapidly applied in the fields of supply chain, credit investigation, product traceability, copyright trading, digital identity, electronic evidence and so on.

Cloud Computing: the explosion of applications such as artificial intelligence, Internet of things and blockchain has spawned strong demand for data computing and storage, resulting in explosive growth of cloud computing markets such as public cloud and full stack cloud. "Cloud" has become one of the new infrastructures in the digital age.


However, these technologies actually have their own application orientation at the beginning. However, in the era of meta universe, all digital technologies are like the general collective creation agreed in the previous life: clear division of labor, performing their duties, integrating the strengths of each family, and jointly building a new species that may surpass everyone's imagination: meta universe.

๏ผˆ4๏ผ‰ Metauniverse: a high-order form of digital civilization

In his book civilization, modernization, value investment and China, Mr. Li Lu defined civilization as "all the achievements created by human beings in their survival and development by using their own resources and the resources in the environment, which is intended to measure the distance between human beings and their closest animal ancestors." At the same time, he pointed out the difference between civilization and culture. "Culture is used to distinguish between different regions and different groups, while civilization is used to describe the commonness of human development and distinguish between human and animal ancestors."

Looking back on human history, every progress in science and technology has raised people's level of understanding the world to a new level, achieved a new leap in their ability to transform the world, and raised the economy, society and human civilization to a new level. With the rapid development of the Internet, as a result of human progress in the past few decades, digital technology has penetrated into various industries and formats, and has become the basis, intermediary and guidance of its development. As a result, the development of politics, economy, culture and society is deeply branded with digital, and the digital commonality of human development is obvious, Mankind has entered the historical stage of digital civilization.

The explosion of digital technology has created digital civilization. Any single technology cannot pry the emergence of new civilization. For example, you will not hear of Internet civilization, big data civilization, cloud computing civilization, etc. Digital civilization is a human civilization based on computer, Internet, artificial intelligence, blockchain, big data, cloud computing, Internet of things and other digital technologies.

The concept of digital civilization has a long history, but the most recent one with the highest degree of consensus is that the top leaders of the country profoundly pointed out in the congratulatory letter caused by the Wuzhen summit of the world Internet Conference held in September 2021: digital technology is being integrated into all fields and the whole process of human economic, political, cultural, social and ecological civilization construction with new ideas, new formats and new models, It has brought extensive and profound impact on human production and life. The theme of this world Internet Conference is "towards a new era of digital civilization". Leaders stressed that we should stimulate the vitality of the digital economy, enhance the effectiveness of the digital government, optimize the digital social environment, build a pattern of digital cooperation, build a solid digital security barrier, let the digital civilization benefit the people of all countries, and promote the construction of a community with a shared future for mankind.

Although 2021 is regarded as "the first year of the meta universe", it should be "the first year of the meta universe exploration". In the era of meta universe, human beings will live in a brand-new economic and ecological environment significantly different from today. If today is regarded as the primary stage of digital civilization, the era of meta universe will be the advanced stage of digital civilization, and the meta universe will be the high-order form of digital civilization.

The reason why this paper defines the current digital civilization as the primary stage is that the digitization of human society has not reached the level of advanced stage, that is, the digitization rate is still in a relatively low stage, and there is still a long way to go from comprehensive digitization. As mentioned earlier, in the primary stage of digital civilization, the physical world dominates human society. In the advanced stage, the digital world will coexist with the physical world!

At this stage, some key digital technologies have just appeared and are still in the exploratory stage, far from mature. Taking artificial intelligence as an example, although the current artificial intelligence technology has made great progress, some obvious problems still exist. The agent itself can not have a good understanding of the natural semantics of the surrounding world and interact smoothly with the real world. Some hardware technologies required by the metauniverse, such as touch technology, need to be further developed. There is also blockchain technology, which is regarded as the last "sky mending stone" to build the meta universe digital technology group. Without a decentralized blockchain, digital identity cannot be unique, digital assets cannot be confirmed, and a trusted economic system cannot be built. However, there are still some problems in the practical application of blockchain technology, such as low performance, low transaction frequency per unit time and lack of ecological environment for technology application, which need to be solved in time. Everything is getting ready! The material conditions leading to the advanced stage of digital civilization have been continuously consolidated, just as some researchers have made analogy and division of digital technology with the help of the theory in Marx's hired labor and capital, which is very vivid and appropriate:

Productivity: 5g, Web3 0. AI, cloud computing power

Means of production: natural data, human data, Internet of things data, digital native data

Production relationship: blockchain

The east wind is also rising! In March 2021, roblox, the first stock of yuanuniverse, was officially listed on the New York Stock Exchange; In August, Pico invested heavily in acquiring VR start-up company Pico; In October, Facebook changed its name to meta and announced that it would transform into a meta universe company within five years. At present, the meta universe has entered the embryonic exploration period. The next decade will usher in the golden decade of the construction of the meta universe. In the next 20-30 years, mankind may enter the meta universe to varying degrees!

๏ผˆ5๏ผ‰ Human civilization: from 1.0 to 3.0

For generations, but time is fleeting. The history of human civilization is the history of the development of productive forces. According to the change of productive forces, mankind has gone through three stages: primitive civilization, agricultural civilization and industrial civilization. Before discussing the fourth stage of human civilization, let's review these three civilizations.

Civilization 1.0: primitive civilization

Primitive civilization is the first stage of human civilization. At this stage, human beings are completely controlled by nature. People must rely on collective strength to survive. Material production activities mainly rely on simple collection, fishing and hunting. The civilization achievements accumulated by mankind at this stage are mainly stone tools, bows and arrows, fire, etc. The time span of primitive civilization is about 60000 years, from about 70000 years ago to about 10000 years ago.

Civilization 2.0: agricultural civilization

Agricultural civilization is the second stage of human civilization. Entering the agricultural civilization, the emergence of iron has made a qualitative leap in human's ability to change nature. Human beings no longer rely on the ready-made food provided by nature. Their main production activities are farming and animal husbandry. By creating appropriate conditions, the species they need can grow and reproduce. At the stage of agricultural civilization, human scientific and technological achievements mainly include: bronze, iron, pottery, writing, papermaking, printing, etc. The time span of agricultural civilization is more than 10000 years, from 10000 BC to the 18th century.

Civilization 3.0: industrial civilization

Industrial civilization is the third stage of human civilization. Industrial civilization is a modern social civilization characterized by industrialization and dominated by mechanized mass production. Its main characteristics are industrialization, urbanization, legalization and democratization, increased mobility of social strata, popularization of education, accelerated information transmission, substantial growth in the proportion of non-agricultural population, sustained economic growth and so on. These characteristics can also be regarded as important factors to promote the transition from traditional agricultural civilization to industrial civilization. The time span of industrial civilization has been about 250 years.

Industrial civilization is an era in which human beings use science and technology as weapons to control and transform nature and achieve unprecedented victory. This is an important period in human history that can not be overemphasized. Looking back on history, the formation process of industrial civilization is based on several industrial revolutions.

The first industrial revolution began in the 1870s, also known as the steam engine revolution. Its symbol is that Watt invented the steam engine, and mankind has entered the era of machine power, or steam age.

The second industrial revolution began in the 1880s, also known as the power revolution. Its mark is the invention of generator, motor and electric lamp, and then the establishment of power transmission and transformation system to produce power industry; Invention of internal combustion engine, emergence of automobile and aviation industry; The invention of electronic tube produced the electronic industry. Mankind has entered the electrical age.

The third industrial revolution began in the 1940s and 1950s, also known as the new scientific and technological revolution. Its symbol is the invention and application of atomic energy, aerospace technology and electronic computers. The new scientific and technological revolution has promoted the development of social productivity and improved labor productivity through the continuous progress of production technology; It has promoted major changes in the socio-economic structure and living structure. As a result, the proportion of the primary industry and the secondary industry in the national economy has decreased, and the proportion of the tertiary industry has increased. It is generally believed that entering the information age.

๏ผˆ6๏ผ‰ New energy revolution: redefining the fourth industrial revolution

Human beings who have experienced three industrial revolutions seem to be experiencing a new round of industrial revolution. There are different opinions on the definition and scope of the fourth industrial revolution, and there are great differences in academia and industry. One view is that the new technological revolution launched in the 21st century is called the fourth industrial revolution, which is a hot concept in recent years: industry 4.0.

According to the traditional formulation, based on the different stages of industrial development, industrial stage 1.0 is the steam engine era, industrial stage 2.0 is the electrification era, and industrial stage 3.0 is the information age (here should be the narrow sense of information, that is, the computer age). Therefore, people define the industrial 4.0 stage as the era of using information technology to promote industrial change, which is called the intelligent era. This concept first appeared in Germany and was officially launched at the Hannover Industrial Expo in 2013. Its core purpose is to improve the competitiveness of German industry and take the lead in the new round of industrial revolution.

However, the author believes that this definition does not fully and accurately reflect the characteristics of the new round of industrial revolution. On the one hand, the so-called "using information technology to promote industrial change" still continues the connotation of industrial stage 3.0, and there is no major innovation; On the other hand, the vigorous new energy revolution should be one of the main contents of the new round of industrial revolution.

The author believes that the fourth industrial revolution should be reconsidered and defined, which may be equated with the new round of industrialization characterized by "new energy revolution".

Human society and nature together constitute the material world. Nature is the premise of the formation of human society. The existence and development of human society in turn affect and restrict nature and constantly change nature. Every iteration of human civilization relies on a great progress in productivity, which also means that mankind has made great progress in using and transforming nature. However, since ancient times, how to live in harmony with nature has always been an important issue facing mankind. In the process of human industrial civilization, the development of industrialization not only drives the progress of society, but also causes the pollution of natural environment and ecological disaster. In other words, the advantage of industrial civilization is that large-scale production has rapidly enriched human commodities and increased the degree of modernization, but the defect is also obvious, that is, the consumption and pollution of the earth's resources are accelerating rapidly.

The energy and environmental crisis has brought people into the new energy era. In the special report on global warming of 1.5 โ„ƒ issued by the United Nations Intergovernmental Panel on climate change (IPCC) in 2018, it is pointed out that in order to achieve the goal of controlling the global warming temperature within 1.5 โ„ƒ, it is necessary to achieve global net zero carbon emission in the middle of the 21st century. Since September 2020, China has stated that it will increase its independent contribution, strive to achieve "carbon peak" of greenhouse gas emissions by 2030 and "carbon neutralization" by 2060.

It is in the context of looking for environmentally friendly alternative energy that the new energy revolution broke out. What is "new energy"? On the basis of new technologies and materials, we will modernize the development and utilization of traditional renewable energy, and replace fossil energy with inexhaustible and recurring renewable energy, which has limited resources and pollutes the environment. Solar energy, wind energy, biomass energy, tidal energy, geothermal energy, hydrogen energy and nuclear energy can be described as new energy.

Today, the global new energy industry giant's industrial practice in full swing has made an important footnote for the new energy revolution. By the end of 2021, the market value of Tesla, the global leader of new energy vehicles, had exceeded US $1 trillion, and the market value of Ningde times, the global leader in power batteries, had also exceeded RMB 1.3 trillion.

Therefore, the fourth industrial revolution = new energy revolution, and the logic seems to be relatively sufficient.

On the new energy revolution, stop here and get back to the point. If the fourth industrial revolution is defined as a new energy revolution, how to understand the "intelligence" in the so-called "industry 4.0"? The author believes that the essence of "intelligence" is an important part of digital civilization, and the intelligent era is also a stage of digital civilization.

๏ผˆ7๏ผ‰ The fourth stage of human civilization should be productivity civilization

Before defining the fourth stage of human civilization, there are two issues that need to be discussed first.

First, the fourth stage of human civilization has not yet started. Is this stage still the continuation of the last civilization? The author has reservations about this. By combing the previous three human civilizations and four industrial revolutions, human civilization 4.0 is ready to emerge, that is, digital civilization. This is because in the history of the development of human civilization, the replacement of old and new civilizations often has a long overlapping period and transition stage. Now we are in such a period. Just like in the early stage of industrial civilization, agricultural civilization still occupies a dominant position. With the continuous improvement of the level of industrialization, industrial civilization is gradually born out of agricultural civilization, and then replaces agricultural civilization and occupies the dominant position of social civilization, thus becoming the mainstream civilization form of human society.

Similarly, the current stage is the early stage of digital civilization. At this time, industrial civilization is dominant. With the continuous improvement of digitization, the digital civilization born of industrial civilization will relay industrial civilization and become the mainstream civilization form of human society in the future. The germination of digital civilization is the computer and other related digital technologies born in the third industrial revolution. Later, we will sort out this process.

Second, different views on what the fourth stage of human civilization is.

It is a general consensus that primitive civilization, agricultural civilization and industrial civilization are defined as the first three stages of human civilization, but there is no unified understanding of the fourth stage of human civilization. There are views that it is knowledge civilization, and there are views that it is ecological civilization. Frankly speaking, these views are reasonable, but they are not completely accurate. The reason is that you need to go back to the basis and standards for the division of different civilizations before you can make a judgment. In other words, from the perspective of productivity, the first three civilizations belong to productivity civilization, and neither knowledge civilization nor ecological civilization is within this framework.

Take ecological civilization as an example. Some scholars pointed out that ecological civilization is a progressive process and positive achievement of the harmonious development of two equal subjects of man and nature. It is an earth civilization including human civilization and natural civilization. Ecological civilization is a relation civilization and a civilization form related to the harmonious relationship between man and nature; There is only one subject of productivity civilization, that is, human beings. Nature is regarded as the object of human transformation and has lost its due subject status. Speaking of this, it is clear that ecological civilization cannot become the fourth stage of human civilization relay industrial civilization.

๏ผˆ8๏ผ‰ Meta universe: leading digital civilization to redefine the fourth stage of human civilization

With the continuous progress of science and technology, people's cognition is also keeping pace with the times. Redefining history is bound to happen. The author believes that the digital civilization entering the meta universe era will redefine human civilization 4.0. Now, let's briefly sort out several key stages of digital civilization.

The computer revolution opened up the computer age.

In the mid-1940s, the electronic computer was born. As one of the important achievements of the third industrial revolution, it also gave birth to the beginning of digital civilization. Some scholars have long proposed the significance of computer to digital civilization. In the book "digital Civilization: Physics and computer" published in 2005, it is believed that "the development of electronic computer has brought mankind into the era of digital civilization." In the 21st century, "computers are entering all fields of production technology, scientific research and social life, completely changing the process of human civilization." The rapid development and wide application of electronic computer has epoch-making significance. It has opened up the computer age.

The Internet era driven by the Internet revolution.

The Internet began with the ARPANET of the U.S. military laboratory in 1969. Since the 1990s, the Internet has been rapidly popularized and applied all over the world. From "PC Internet" to "mobile Internet", both the world and China, industry and people's livelihood have experienced magnificent changes. The emergence of the Internet can be compared with the inventions of "fire" and "electricity" in the history of science and technology. The "Internet revolution" is vigorous and vigorous, and the Internet era is vibrant. "Internet plus" and "+ Internet" have become a common phenomenon. Many new technologies, new products and new models have emerged in human society. The Internet has expanded to all areas of society and began to deeply change the social form of human beings. Since the Internet, mankind has entered the Internet era.

The era of intelligence led by the revolution of artificial intelligence.

Artificial intelligence was put forward even before the emergence of the Internet. In 1956, the concept of "artificial intelligence" was first put forward at a summer discussion meeting held by Dartmouth College. Although the concept is advanced, the infrastructure is weak, so the progress of artificial intelligence in the 20th century is very slow. Until recent years, the development of cloud computing and big data has provided AI with unique material conditions; More importantly, the "deep learning" method based on multi-layer computer chip neural network has transformed artificial intelligence and opened a new era of machine intelligence. Artificial intelligence technology is widely used in various fields of people's life. Image recognition, speech recognition, robot and expert system all make artificial intelligence technology more and more mature.

In the Book Intelligent revolution published in 2017, it is pointed out that the industry usually divides artificial intelligence into three stages: weak artificial intelligence stage, strong artificial intelligence stage and super artificial intelligence stage. Although the evolution and far-reaching influence of artificial intelligence in the future technology must be beyond imagination, we are still in the stage of "weak artificial intelligence" at this stage. However, the argument that "artificial intelligence is the second half of the Internet" is not unreasonable. It should be added that the large-scale application of artificial intelligence in the industrial field is essentially the connotation of the so-called "industry 4.0". Since then, mankind has entered the era of artificial intelligence.

It can be seen from the above that before the advent of the meta cosmic era, digital civilization can not be compared with the previous three civilizations. At best, it is a sub civilization of industrial civilization, and it is too early to relay industrial civilization with digital civilization. But looking at the future, today, the computer age, the Internet age and the weak artificial intelligence age, which were born out of industrial civilization, have formed the primary stage of digital civilization.

The result of the artificial intelligence era is to realize the super intelligence of the real world and make the real world intelligent through transformation; The result of the meta universe era is to directly create an intelligent virtual world. In the future, the intelligent real world and the intelligent virtual world will merge and coexist. After entering the digital civilization of the advanced stage of the meta universe, the comprehensive digitization, so that the highly intelligent digital civilization will complete the final upgrading and replacement of the industrial civilization and fully shoulder the important task of the new stage of human civilization.

The digital technology group revolution in the meta universe era can not be simply regarded as another industrial revolution, but will lead the upgrading of civilization and the inevitable iteration of digital civilization to the previous agricultural civilization and industrial civilization. Take the digital economy as an example. According to the data of the white paper on the global digital economy issued by the China Institute of information and communications, in 2020, the added value of the digital economy in 47 countries reached 32.6 trillion US dollars, accounting for 43.7% of GDP; In 2020, the scale of China's digital economy will reach 39.2 trillion yuan, accounting for 38.6% of GDP, maintaining a high growth rate of 9.7%, and becoming a key driving force for stable economic growth. Digital economy is only the beginning of digital civilization. According to the logic that the economic foundation determines the superstructure, as a new context of the development of the times, digital civilization is and will further reconstruct the multidirectionality of mankind, such as political civilization, industrial civilization and ecological civilization.

According to the name of each stage of industrial civilization, the above stages of digital civilization, such as the digital 1.0 stage in the computer age, the Digital 2.0 stage in the Internet age, the digital 3.0 stage in the artificial intelligence age and the digital 4.0 stage in the meta universe age. So redefined, but there is no sense of conflict.

The future has come and will come. "Do not underestimate in the long term, do not overestimate in the short term" or our rational state. A family's words, deficiencies are inevitable; Throw a brick to attract jade and discuss it together. (end)
