Juchen had just graduated shortly after he used to eat under a big beautiful boss, but, time has passed, and then the big beauty left the company, and married her boyfriend, only occasionally has a little contact with Juchen, it should have been two or three years since the last interaction, but I didn't expect to send Juchen a WeChat message now, greetings: "I heard that you were injured?"

Ju Chen: "Well, the minor injury will be completely recovered in a year or two." He replied not without self-deprecation.

Old boss: "A year or two! Oh my God, it looks serious." Do you know what is the most important ability of a successful person? It is not to do what to do, but to learn to fail. Like Cao Cao, he has fought so many battles in his life, and he has gone into battle in person, and many defeats can be retreated. It's the same with entrepreneurship, 95% of startups are doomed to failure, you know? So, you have to learn to defeat battles. The way to do this is to retreat step by step! Or learn from Zeng Guofan, repeatedly defeated and defeated! Wait for the opportunity, don't give up. Don't change your face immediately when you encounter setbacks, just like Sichuan Opera changes your face......"

It seems to make sense, but Juchen has long passed the age of being educated, so he just smiled slightly and responded lazily.

His current state must be unimaginable to the old boss, the old boss is a talent, but Juchen now thinks that he is a ghost talent, and he has unpredictable opportunities.

He suddenly became interested in other things from his old boss, such as: "Have you given birth?

The old boss: "What kind of baby? I don't have time to give birth to a baby, I'm busy, the company is going to IPO recently, and I'm really busy." ”

Ju Chen: "What company?"

Old boss: "I'm still making games." ”

Juchen: "Oh, doesn't that mean you've been in the game industry for 7 or 8 years?"

Old boss: "Yes, time flies quickly, it's better than you with a hammer in the east and a stick in the west, how good it is that you have been following me, and now you are at least the middle level." ”

Ju Chen: "I know that if I can turn back time, I will definitely follow you, but when I was young, I was young and vigorous, and I thought very highly of myself, so I didn't hit the south wall and didn't look back, I can't help it, people, I need to grow." Only after leaving you will know that it is better to be managed by others than to be managed by you. ”

Old boss: "You finally know! You come to our company, start from the bottom, with your intelligence, I will soon be able to promote you." ”

Juchen: "Thank you, though, I'm not interested in the game right now. ”

Old boss: "So what are you interested in?"

Ju Chen: "Ethereum. ”

Old boss: "...... What is Ethereum?"

Juchen: "If I don't understand, I'm too lazy to popularize science, I'm going to be busy, I'll get back in touch." ”

He set a Pomodoro timer on his phone, worked for 25 minutes, took a 5-minute break, and when it was time to work, he put down whatever he was doing and went to study Ethereum.

The old boss investigated it, and then sarcastically mocked him: "Engaging in this strange thing again, this investment cycle is too long, it's useless!"

Juchen's mobile phone entered the DND mode, and he didn't check his phone until the end of 25 minutes.

He replied: "If you don't have a dream, what's the difference between it and grandma's food? I'm exploring a set of TDD, decentralized programming, in the future, programmers will be split into two groups, one is to write a test, this test is not a general test, each test has a price code, as long as the program passes the test, it will be issued immediately, this process is written in the smart contract, no one can change it, now the biggest problem is that the test itself also needs to be tested, so, how to write the test of the test?"

The old boss finally said: "I don't know how to feel it! However, it seems to be very unreliable, am I really grandma's food?"

Ju Chen: "It's right if you don't know, you girls shouldn't know technology, so leave the dirty and tiring work of technology to us men." I'm in surprisingly good shape now, whether it's grandma's dish or truffle, caviar, foie gras, it depends on this wave of operations. ”

Old boss: "Need help?"

Ju Chen: "...... Uh, if you can, you can lend me some money, I ate instant noodles until I wanted to throw up. ”

Old boss: "How much?"

Ju Chen: "Can you still manage enough?" Just send a red envelope to encourage you." ”

Old boss: "I asked you how much, or so on, how long does it take to develop to a small achievement?"

Juchen: "Three years." ”

The old boss didn't respond for a long time, and finally issued an exclamation: "Alas!"

Juchen: "Three years of sharpening a sword, okay, my Pomodoro is here again, see you later!"

The old boss thought twice and gave Juchen 10,000 yuan, and Juchen sent a fist-hugging expression to show his gratitude.

Since he was given the money, Juchen felt that it was necessary for him to report the recent progress to his old boss in a few days, for example, he was developing a program that could make "test cases" with a click of the mouse and a keyboard input, so that product managers and even ordinary users could also participate in the programming of the test, lowering the threshold to no less.

Programmers can rush to test and develop like food delivery riders, and the system will record the efficiency of programmers to prepare for intelligent order dispatch in the future. The people who make the tests are also efficient, because they are responsible for specifying the bonus for each test, and if it is distributed properly, they will also be rewarded, and the tester is above the "webmaster". The first webmaster, without a doubt, must be the "root programmer" who knows the system best, Ju Chen.

The old boss read Juchen's report and teased: "Huh, it seems that your career as a rider can also bring you unexpected inspiration!"

Juchen said proudly: "Do you think I will be willing to make a group of grandmother's dishes with the spirit of craftsmen?"

Old boss: "You thing, can I show our programmers? ”

Ju Chen: "Yes, this technology is very complicated, and other programmers can only give opinions, and they can't fully understand it." ”

The old boss showed several programmers, but only one young programmer was very interested in the project and expressed his intention to join the project team.

Juchen just wanted to find someone to try out his system, so he agreed, explained more ideas to him, and then, the programmer brother became even more interested, and strongly asked Juchen to go out of the mountain and return to Metropolitan Cotton Tree City, not to nest in a small county.

Juchen's answer was: "It's not time yet." ”

The addition of young programmers has greatly accelerated Juchen's programming speed, because Juchen himself is one-handed typing, and after the little brother joins, he can reflect his programming intentions through testing, and now sell his entire system.

The little brother said to his old boss Pei Li: "Your friend has a strange personality, and he treats me as if he is a decentralized node." ”

Although Pei Li is already thirty years old, she is still so pretty, she smiled and said, "He was injured just now, and he typed with one hand, so he should be considerate of the wounded and sick." It will be fine later. "But whether it will be really good, it's really hard to say, because Pei Li has already discovered that Ju Chen seems to be quite cold to Pei Li's old boss, even if she Pei Li gave him 10,000 yuan like Song Gongming in time.

She really guessed correctly, Ju Chen's heart has followed Ethereum and his project, full, can't accommodate anything else, any people and things that may disturb his state will be thrown aside, and he won't consider drinking coffee and drinking wine together, which is normal for ordinary people, so as not to cause trouble.

The so-called sideways branches are not without living examples, and this little brother in front of him is one, because he mentioned to Ju Chen that day that he likes to watch "The Three-Body Problem" very much, and asked: "Has Brother Chen seen it?"

Juchen: "I've seen it. ”

Brother: "Do you like it?"

Juchen: "I like it very much, but it's ......"

Little brother: "But what?"

Ju Chen: "It's not just like you, I have a lot of ideas myself, and I don't approve of a lot of black technology in it." ”

Little brother: "Let's listen to it, I like to watch others criticize Da Liu the most, and then I will support my idol." ”

Ju Chen: "What impressed you the most in it?"

Little brother: "Of course it's the law of the dark forest, it's a masterpiece of gods." Do you agree with this? The chain of suspicion is simply wonderful. ”

Ju Chen: "Walking in the dark forest, I heard a movement in front of me, regardless of thirty-seven twenty-one, shoot a shot?"

Little brother: "That's right! Because you don't know if the other party is a good person, the best way is to kill them! Survival is the first need of civilization." ”

Ju Chen: "Who told you that survival is the first need of civilization?"

Brother: "Uh...... Of course it's Da Liu, of course, isn't it?"

Ju Chen: "You don't understand Darwin, and Da Liu doesn't really understand Darwin." Natural selection, survival of the fittest, survivors do not know why they were chosen by nature, they just live blindly. The Denisovans died, the Neanderthals went extinct, the Mesopotamian civilization was destroyed, and ancient Egypt was gone, were they once desperate to survive?

I'm afraid that civilization does not have such a strong vitality. Even the source of Western civilization, the ancient Greek civilization, was once sealed in the dust, until it was discovered by archaeologists and recognized as the source of science. You and I stand here, living in the moment, not by the choice of our ancestors, but by inexplicable survivors.

There's a term called survivorship bias, people who survive always think they're doing something right, but they're not, they're not that hard, they're not so witty, they're like a group of monkeys sitting in front of a computer competing in stocks, the code appears in front of them, and there are two buttons in front of them, one is 'invest', the other is 'don't invest', and there is always a monkey who wins, if you can communicate with him and ask him the secret of investing, he will tell you to scratch your armpits before each investment, so that you win.

Civilization is no better, and it is also an ignorant monkey. Like Da Liu's imagination, human beings will definitely unite in the face of the crisis, which is a lack of understanding of natural selection, human beings, Homo sapiens, will definitely not unite, because we are survivors, we will definitely be divided, and in the face of the crisis to adopt our own strategy, and then some individuals will survive the catastrophe in ways you don't expect. ”

Brother: "Okay...... But the chain of suspicion is really exciting, right?"

Ju Chen: "It's wonderful because it has the blood of conspiracy theories, do you think it's very rigorous? Actually, otherwise, I can find a loophole, just take the well-known metaphor - shoot when you hear a sound? It doesn't cost to shoot? Moreover, you have a shotgun, but how do you know that the other party doesn't have a shotgun? Originally, people didn't provoke you, you thought he was a weak civilization, give him a shot, didn't expect the other party to have a shotgun, right?

Even if they are a weak civilization, do you know the 'technological explosion' that is talked about in the chain of suspicion? You look at the other person with bare hands, but a technological explosion, people have a shotgun or a grenade in their hands, so what is the best way to discover civilization? Don't hit it, but avoid it! God knows what guy has in his hand? Or what weapon he will invent before your attack is reached.

If you see a colorful snake in the forest, you'd better not provoke it, maybe he will spew venom, civilization, a hundred times stronger than a poisonous snake beast, you have to have a sense of awe for civilization, and going to war may mean digging your own grave.

I can also come to a chain of suspicion, my conclusion is just the opposite, you must avoid civilization when encountering, because the other party is likely not vegetarian, and before your blow is reached, the other party may develop a powerful technique to fight back.

Why does the Great Silence of the Universe exist? It is not because it is necessary to attack those civilizations whose coordinates have been exposed, but on the contrary, the reason for the Great Silence is that it must not easily attack other civilizations, no matter how weak they are. The Dark Forest is not scary, but what is scary is the civilization that is self-righteous and does not have enough reverence for the 'other'. ”

The little brother said he was helpless: "This ...... It seems to make sense, but it's still dark, and it's better not to expose yourself, that's always right, right?"

Juchen spoke: "That's not necessarily, I'm just following some of Liu Da's settings, in fact, the reason for the great silence is probably not the so-called cosmic sociological reasons, but something else, for example, when civilization develops to a certain extent, it is likely that it is no longer aggressive, but tends to be introverted, and human beings will not endlessly go to the stars and seas, but will explore themselves to the microcosm."

The truth of this has already emerged: if you look at the rich and developed countries, which other country has a growing population? No. What does it mean that Europe, RB, South Korea, Taiwan, and Hong Kong have low birth rates, while the population growth of the United States and Germany mainly depends on immigration?

Some so-called sociologists say that this is because industrialization has led to the increase in the cost of raising children for families, which is all nonsense, in essence, human beings are gradually realizing the way to satisfy their desires and no longer follow the old habits. For example, TV series and games can well satisfy human desires, so that human beings no longer need to get ahead in reality. Otaku is the future of mankind. ”

At this time, the little brother seems to have woken up, this guy named Brother Chen, seems to have pointed out a major bug in Liu Da's cosmic sociology, the chain of suspicion can't go on, the technological explosion may not only cause a clash of civilizations, but also contain the conflict, as if it is still the Age of Discovery, the Europeans discovered the New World, if when their expeditionary force arrives in the New World, it is likely that the technological explosion will produce more powerful weapons than the colonists, then do they dare to go?

The little brother himself thought of an example, saying: "The possibility of technological explosion is like the nuclear arsenals that promised to destroy each other during the Cold War, but it brought a rare peace, isn't it Brother Chen?"

Ju Chen: "Haha, that's it. ”

Little brother: "Brother Chen is really a talent, why don't you publish such an interesting discovery?" No wonder Sister Pei Li values you so much!"

Ju Chen: "I also like "The Three-Body Problem", however, I prefer to find faults and raise the bar, in fact, there are still many hard injuries, do you want to hear about it?" he was very interested.

Little brother: "Of course, let's talk about it." ”

Ju Chen: "The transparent thinking of the Trisolaran, from an evolutionary point of view, is impossible, because it means that there is no competition within the species, and competition is one of the biggest evolutionary drivers. In terms of mathematical models, scientists have long simulated that a good competitive strategy requires individuals to maintain their own privacy, otherwise neither the individual nor the race will be competitive, and there will be no competitiveness in the single-cell era, let alone animals and primates. ”

Brother: "Uh...... Brother Dust has a soft spot for evolutionary theory. ”

Ju Chen: "Of course, Darwin is definitely a supermaster who unveiled a biological age, and there are 6,500 books related to Darwin. In fact, from an evolutionary point of view alone, Trisolarans should not exist at all, because their stars are very tyrannical and have too much influence on the speed of evolution. Evolution is an amazing thing, but it's also time-consuming. Have you ever heard of the Cambrian explosion of life?"

Little brother: "I heard that it was an evolutionary spectacle that happened 500 million years ago. ”

Ju Chen: "Yes, that was about 500 million years ago, and the history of the earth is 4.6 billion years, and 4 billion years have passed since the explosion of life!

When our earth was just born, there was a planet the size of Mars that collided and formed the moon, the moon is a very rare huge satellite, which ensures that the earth has a stable axis of rotation, so the north and south poles of the earth are very stable, otherwise, the north and south poles will shake in a short period of time, the climate is unstable, I am afraid that until now, even the Cambrian explosion has not appeared.

You say that the three stars are super unstable, and the trisolaran star with asteroid rain at two ends in three days can have a stable evolutionary environment? So, at most, the Trisolaran only has bacteria, just like the simple life that might exist on our moons above Jupiter and Saturn. ”

Little brother: "This ...... It seems to make a lot of sense.,But,Novels.,It must be set up wonderfully.,How can you do things without a three-body person?Dimensionality reduction attack is also very interesting.,Right?,I know,It's definitely not scientific......"

Ju Chen: "It's absolutely unscientific, because physicists' so-called multi-dimensional space refers to the strange explanation of the strange phenomena that occur on the quantum scale, which is not necessarily correct. At the macroscopic scale, there is no such thing as multidimensionality, that is, three-dimensional, without any bending. Of course, Tomoko can't exist, because space can't be spread out and spread to the size of the earth. ”

Little brother: "IT bigwigs like the concept of dimensionality reduction and survival!"

Ju Chen: "People from the Association for Science and Technology, who don't have much scientific literacy, said that the number of people with scientific literacy in China has increased by 90%, from 3%+ to 6%+. Their so-called dimensionality reduction attack is just a combination of the Internet and offline. They simply don't understand the nature of space, that the universe is flat, absolutely three-dimensional, and that two straight lines will never intersect."

The little brother smiled: "Brother Chen, although you are more knowledgeable than me, but are you talking too much and forgetting all the basic scientific knowledge? Einstein's theory of relativity says that space can be bent!"

Ju Chen: "That is the effect of having mass to cause space to bend, and space itself is flat, scientists have measured galaxies from far away, and found that their light has always remained parallel, the so-called distant, is hundreds of millions of light years, this ruler is enough to prove that the entire universe is flat, and it is also the recent progress of cosmology, the universe is likely to be infinite, some people have said before that the universe is curved, and you will return to the original point if you go all the way from any point, which is wrong." ”

The little brother was finally shocked: "Ah? really? sure? My cosmological knowledge has always stayed on the fact that the size of the universe is limited! Incredible, I have thought that the universe should be infinite since I was a child, but after learning some knowledge, I realized that the universe was big bang and that the universe also had a beginning. I didn't expect to go around and go back to the original infinite universe, and that's good, I still like the infinite universe!"

Ju Chen: "What's the use of infinity? It's as if you can travel to a galaxy far away, but unfortunately, we're afraid we can't even get out of the solar system." ”

Little brother: "No, no, no, the infinite universe is very interesting, it means that there are infinite possibilities, it means that there will be a person exactly like me in a distant place, who is discussing cosmology with another dust brother, and I feel fascinated when I think about it." ”

Ju Chen: "Unfortunately, I can responsibly tell you that your romantic imagination does not exist, because there can be no two exactly the same thing, since the universe is infinitely large, it means that the universe is also infinitely small, since it is infinitely small, then every cell and every atom in your body can be infinitely subdivided, and any inconspicuous little point is another magnificent and magnificent universe, thus becoming an entity that cannot be copied, so there is no identical you or me." ”

Brother: "Uh...... This one...... It's a bit hard to accept, Brother Chen really likes to lift the bar. Can't you just say something nice?"

Juchen: "Heaven and earth are neither benevolent nor evil, and all things are used as dogs." What is good? Does a good sound make people happy? Not necessarily. If a girl says, 'You're a good person,' will you be happy? So, there may be murderous intentions behind good words, but bad words may bring you benefits. ”

Little brother: "Brother Chen, you should be a philosopher, I will take it." ”

Ju Chen: "Philosophy is useless, philosophers are just useless grandmother dishes...... Damn, my Pomodoro timer is running out, so I'm going to write code instead of messing with you. ”
