"Technology is limitless, but human beings are limited. When technology develops to a certain point, it will come to a standstill. ”

Leng Qingqiu said.

As he spoke, he took the cigarette case from the side, took out a cigarette, and lit it on the spot.

Take a deep breath and feel comfortable.

Leng Qingqiu said, "Do you want one?" ”

"No, you don't!"

Xiang Yudao.

He doesn't smoke because he doesn't need to.

For example, on communications.

Opened in 2205 AD, it is the 7G era. However, some countries still use 5G networks because they do not need 7G networks.

5G communication is enough, so why spend money.

Similarly, most countries on the planet have entered the era of digital currency, but there are still a large proportion of countries and civilians who use bank cards and paper money...... Because it doesn't need to.

On the earth, maglev cars have been manufactured, but many people still use internal combustion engine vehicles...... Not because it's not advanced, it's because it's not needed.

In the same way, some countries have built subways and buses, and the transportation is very convenient. People don't need to buy cars anymore...... Because it doesn't need to.

"A man can't stop smoking!" Leng Qingqiu said.

Xiang Yu was silent and did not respond.

Leng Qingqiu said: "The use of steam technology, called the first industrial revolution: the application of internal combustion engines and electricity, is the second industrial revolution. Then, the use of computers, nuclear energy, aerospace, bioengineering, etc., for the third industrial revolution! ”

"Then, in the 21st century, the fourth industrial revolution began, mainly involving artificial intelligence, new materials technology, molecular engineering, graphene, virtual reality, quantum information technology, controlled nuclear fusion, clean energy and biotechnology as technological breakthroughs."

"Artificial intelligence has shortcomings, simple zero-sum one, can not simulate the complex thinking of human beings, and falls into a bottleneck, but only develops a biological computer with great defects!"

"New materials have also been developed, human beings have successfully landed on the moon, landed on Mars, and even Pluto has successfully landed, established a lunar immigration base, a Mars immigration base, but the cost of immigration is high, the population is too small, mainly scientific research!"

"Virtual technology, because it destroys privacy and human morality, is directly banned!"

"Quantum information technology, because of the lack of market, ends without a problem!"

"As for controlled nuclear fusion, it's a joke at all!"

"The so-called Fourth Industrial Revolution does not have the previous three glories at all...... From the 21st century to the present, about a thousand years, human science and technology in general, are in a state of stagnation...... This kind of stagnation, as if the Qin Dynasty in China reached the Qing Dynasty, seems to be progressing, but this progress is extremely slow! ”

"Until a hundred years ago, because of a fortuitous accident, mankind started the fifth industrial revolution!"

"An accident!" Xiang Yu was slightly surprised.

Leng Qingqiu continued: "That is, a hundred years ago, when a scientist was doing an experiment, there was an accident, because of this accident...... The scientist accidentally pioneered the Space Gate technology...... It can also be called stargate technology! ”

"The door of space, which can communicate with another planet, shorten the distance of the universe and accelerate the exchange of civilizations, can be called the greatest invention in a thousand years, there is no one!"

Speaking of this, Leng Qingqiu became sad.

"The degree of development of civilization mainly depends on three points, one is the amount of resources, one is the degree of civilization exchange, and the other is the degree of civilization protection."

"If there is no tooth war, the exchange between the East and the West after the war, Yanhuang may still be in reincarnation, and it may be a feudal society today, thousands of years later!"

"If Europe had not opened up new shipping routes, absorbed the cultural essence of the East, and absorbed the resources of North America, perhaps Europe would still be dark thousands of years later!"

"The exchange and collision of Eastern and Western civilizations gave rise to three industrial revolutions. However, the foundation of human civilization, after the opening of the three industrial technological revolutions, has been exhausted! ”

"We must absorb the new civilization heritage in order for the earth's civilization to go further!"

"However, the starry sky is too vast, and the closest living planet to Earth may take six light-years...... And the fastest spaceship of mankind is only one hundredth of the speed of light...... It will take at least six hundred years! ”

"With the current speed of spacecraft, maybe 100,000 years have passed on Earth, and it has only flown a short distance, less than a hundred light-years...... With such a narrow radius, it is very difficult, almost impossible to find a cosmic civilization! ”

"However, with the space gate, you can connect a planet, which is much more affordable than a spaceship in terms of cost, you can get rich resources, you can absorb the nutrients of other civilizations, and vigorously develop!"

"Every time the door of space is opened, it consumes a huge amount of electricity and resources, and only the top power qualifications can open it, a total of nine times, five times is a desolate planet, there are sufficient resources, but it is not suitable for human survival. The remaining four times are the planets that have a very suitable environment, an atmosphere, plants, and animals, which are suitable for human survival...... It doesn't require any modifications, and it is suitable for human immigration! ”

"It's a pity that there is no intelligent life on these planets, just wild planets, and no civilization has opened!"

"The ninth time, opened a planet, the diameter of this planet is one million kilometers, the area is huge, the environment is suitable, and what is even more amazing is that there is an intelligent civilization on this planet, but the degree of civilization is low, and the intelligent life here is similar to the human race, but it is in a primitive society, known as the cave civilization! Those primitive humans, also known as cave people. ”

And so an invasion began...... Many people expected that in the near future, the planet would become a human colony planet. Humanity will occupy the planet just as white people did when they occupied the Americas......"

"However, humans overestimate their own capabilities...... This seemingly weak civilization, which was not weak at all, began to counterattack humanity after experiencing an initial defeat...... Humanity is in a catastrophe of annihilation...... The countdown to the destruction of the earth's civilization has begun, and it may only take a hundred years for human civilization to completely perish! ”

As he spoke, sadness flashed in Leng Qingqiu's eyes.

"The earth is not special in the universe, it is not the only one, it can be replaced at any time, it can be destroyed. If the earth's civilization is destroyed, it may be like a leaf falling from a tree, insignificant! ”

"Wait!"

Xiang Yu was puzzled: "Those cave people are physically strong and powerful, but human beings are not vulnerable...... Humanity has missiles, heavy artillery, and nuclear bombs, which are enough to destroy all strong enemies! ”

Leng Qingqiu also smiled: "Many earthlings also think the same way, but ten years ago, Kunlun Continent fell!" ”
