When Yuko wakes up again, she finds an unfamiliar white ceiling.

This was followed by a pungent smell of potion.

She felt a pain in her temples, and only after frowning and regaining some consciousness did she remember what had happened—

I felt like I had fainted in the small courtyard of the orphanage.

"That's right! What about Sally? Sally! ”

Yuko suddenly got up from the bed, and then she found her father who was sitting on the edge of the bed peeling an apple for herself.

"Are you awake?" Sakura Masao's face was even older and haggard than before, but he still managed to squeeze out a smile, "You've fainted for a day and a night, be hungry, eat an apple." ”

Yuko anxiously grabbed her father's arm: "Dad, where is Sally?" ”

Masao Sakura was silent for a long time before he shook his head lightly - he understood that sooner or later his daughter would have to face the truth.

That day, Sally passed by the paramedics who rushed to the scene, but it was too late......

Yuko shook her head desperately after being stunned for several minutes.

"Dad, you must be lying to me, no, Sally is still waiting for me, we have to give her a welcome party, is the French restaurant booked?" Daddy is really! ”

With that, she got out of bed and went to the orphanage to find Sally.

"Yuko!"

Masao Sakura grabbed his daughter's shoulders and looked pained, "Sally is no longer in this world!" ”

It was only after Masao repeatedly comforted Yuko that she accepted this fact.

At this time, all kinds of pictures of being with Sally before appeared in Yuko's mind like a marquee.

The two of them sat in the corner of the orphanage cafeteria and chatted happily......

The two of them sat on the windowsill of the small room and watched the sun go down and the moon went up......

The two of them lay on the small wooden bed with their fingers interlocked and hugged each other......

Then Yuko completely broke down, threw herself into her father's arms, and began to cry and cry like rain.

The ward was quiet, and only Yuko's sobs could be heard, and Masao Sakura gently patted Yuko's shoulder, but couldn't say a word.

It was pouring rain outside the window, as if the sky was sad about it......

……

Since then, Yuko has completely changed as a person.

She locked herself in her room all day, and Sally's funeral was not there.

Since then, news has continued to come about this incident.

Because of the murder, the city council and the government began to intervene to investigate the business qualifications of the orphanage.

The director and staff of the orphanage blamed each other in the tribunal, believing that their actions were trivial and that the negligence of others was responsible for Sally's death.

The children at the orphanage who bullied Sally also cried in fear in front of the police, accusing each other of their friends for bullying Sally more often than themselves.

But they don't know—

Yes, Yuko thinks, they will never know.

The adults in the tribunal will not know, they will only care about whether it will affect their job prospects and salary.

The little boys who were arguing with each other wouldn't know about it, and they would just pick one more "Sally" from among the weaklings when the matter had subsided, and continue with their previous behavior.

Yuko suddenly felt that she could no longer believe in the world.

Since Sally's death, Yuko's personality has also completely collapsed.

She has become a sick girl, and treats everyone with a playful and cold attitude.

She became a science madman, giving up the campus youth life of her peers, and instead buried herself in the laboratory all day long, concentrating on the development of the artificial intelligence emotion module codenamed to give the artificial intelligence a soul.

"Sometimes, those silicon-based organisms may be more like the first form of human beings when they were born as babies than carbon-based organisms, and the generalized consciousness of human beings has been polluted, and the times have begun to collapse, and this situation must be corrected as soon as possible."

This is the text that twelve-year-old Yuko wrote in her diary.

After the Uchime Company, where Masao Sakura works, officially launched the Uchime Project, she was able to continue her development experiments using the resources of the Utahime Company.

However, this was followed by opposition from fathers and international scientists.

Regardless of whether it is technically possible or not, from a purely scientific and ethical point of view, they also strongly oppose Yuko's behavior of giving souls and emotions to those robots with the permutations of 0 and 1 in their heads.

There are already too many films, televisions and works in this world, warning people not to try to move this Pandora's box.

Yuko insists that the personality of True Tears can only implant a lot of good and correct things, and eliminate those bad things.

She once hid from her father and added the touch of True Tears to an experiment planned by Singer, and in that experiment, the Android robot's hand was close to Yuko's head for no reason.

Masao Sakura judged that this was the robot's attack, so he destroyed the robot's head with an iron rod, ending the experiment, and the conflict between the father and daughter intensified.

She has also spoken to opponents of the scientific community at the International Artificial Intelligence Conference:

"Youzi-san, you are still young, and your future development is limitless. Your ingenuity should be used for the benefit of humanity in other ways, not in this crooked way. A middle-aged scientist earnestly persuaded.

"It's not a crooked way!" Yuko insisted,

"You should have heard what I just said about the phenomenon of human groups, and I called it why that little girl named Sally was in this predicament, because the whole orphanage lacked the right education.

No one taught the children how to behave properly with others, and no one taught the directors and staff how to behave when they were young.

And the True Tears are closer to the original appearance of human beings, I will remove those greedy and violent factors of the jungle, and let it replace the inexperienced parents to educate the next generation, so as to change this era and improve humanity itself! ”

"Although I also sympathize with the little girl named Sally you said, a scientist should be objective and neutral, and should not have too much of a Madonna complex. If you are familiar with human history, you know that the entire development of mankind has been accompanied by blood and killing. The opponent immediately refuted,

"Yuko, many of the technologies you can enjoy in modern life were originally invented with the war of the jungle.

Going back further, without the Age of Discovery and colonization, we would not have been able to complete primitive accumulation, and the world would not be what it is now.

Lust, greed, the law of the jungle, these are things that are engraved in human genes and inherited from the age of the beast. In a sense, this thing fills our whole world with vitality.

If we have the desire, we will keep launching vehicles into outer space in search of new colonies. There's the jungle that will serve our Thanksgiving table with a delicious turkey instead of hay or rotten leaves.

The land under our feet is not the home of the Indians, it is the home of the strong, and whoever has a hard fist is the master here, which is fair.

Humans simply don't need such a strange thing as true tears to educate and transform themselves and the next generation, and the desire and predator in genes are the wealth left to us by our ancestors in their primitive hunting life. ”

"You're a sophistry, sir, and I'm ashamed of you to say such things as a scientist." Yuko excitedly slapped the table on the forum.

She sneered: "According to you, if there is a big man who is beating you now, beating you to the point that you don't have a few front teeth left, and then goes to live in your two-story villa and does not leave, and also occupies your wife, I think you had better not have any grievances."

After all, his fists are harder than yours, and whoever has a hard fist can live in your villa and sleep with your wife, which is very fair, and this is also the wealth left to us by our ancestors. ”

"You ......" the scientist froze, and the others on the forum let out a burst of laughter.

Yuko continued: "It is precisely in order to prevent this gentleman's villa and wife from being occupied by barbarians that humanity has produced law, morality, and order, and these things have produced essential differences between humans and beasts.

And the tears of truth were born precisely so that a person can learn these things from an early age.

Put it on the robot nursery to assist the newborn's life enlightenment, orphans in orphanages can learn how to love others correctly from an early age, drunkards and gamblers will no longer educate sons who do not learn and do not know, and dusty women will no longer educate their profligate daughters.

If in the future, every newly-born human being can receive the right training and high-end education, then reincarnation will not be a technical life. After two or three generations of filtering and genetic refinement, the overall quality of humanity will certainly rise to another level.

At that time, the parents of every newborn were high-quality human beings, and the mission of True Tears was completely over. ”

Yuko then continued: "The current differentiation of people in the world is essentially the same level of education.

Most upper-class parents have high knowledge, high quality and high emotional intelligence, and the children they raise will not be much worse.

And most of the parents of sheep herding babies, in addition to teaching their children how to herd sheep more skillfully from an early age, there is nothing else to teach, at most there is something delicious and good to wear, all for the baby, this is their greatest love, but this is not to blame them.

That is to say, dragons give birth to dragons and phoenixes, and the children of rats will make holes. The son of the elite is still the elite with a high probability, and the son of the sheep herding baby is still the sheep herding baby with a high probability.

However, it is not the same to add real tears to the family of the sheep herder, it can assist the parents of the sheep herding baby to educate their children, so that they can at least get high-end training like the sons of the elite, so that they can grow up correctly.

"Cut, if that's the case, education will be completely fair, they are all high-level people, who will do the dirty work, who wants to sweep the streets? The city must not smell bad, right? The scientist said dismissively.

"Isn't that what the development of artificial intelligence and robotics is all about?" Yuko replied, "The existence of robots is to liberate humans from monotonous and low-end labor, while the existence of artificial intelligence is to break down the barriers of education and ensure that every human can receive low-cost high-end training from birth."

If all human beings are freed from intrigue and oppression for survival and concentrate on science, art, and space exploration, then the process of human civilization will certainly be accelerated.

The emergence of artificial intelligence and robots is what makes Plato's world closer and closer. ”

"Naïve, naïve. Yuko-san, when you become an adult, you will look back on this rhetoric, and you will realize how naïve you are. ”

The reason why this opponent is so sure is that he has seen through the essence of human beings. Plato's has been completed for thousands of years, but it was followed by the Age of Dark Slaves.

Moreover, even if Yuko's utopia really comes true one day, he will not be happy to see it.

Because he obviously belongs to what he says, the high-quality life brought about by class solidification and the treatment of the inferior people, so he naturally does not want these lower-class people to break through the class barrier and sit on an equal footing with him.

Happiness comes from comparison, and if those who are lower than themselves have developed to the same level as themselves, then their happiness will most likely decrease.

It's like in the orphanage, those orphans keep saying, "No matter how good I am, I'm better than Sally, right?" "Come and comfort yourself.

In his opinion, it is an unsolvable problem, and all everyone can do is to climb up desperately to avoid becoming "Sally".

At this time, a slightly older scholar interjected: "Both, you both ignore an important factor in your argument, and that is. Plato's ideal state could not be realized at that time because the productive forces were too low.

If everyone in the city-state was engaged in research and literature, and no one was hunting and planting, then they would all starve to death. There were no robots to do the work for them, so they went to catch slaves.

Whether the world in Yuko's mouth can be realized depends on whether the productivity can reach that level. It is unlikely that every family will be able to install an auxiliary childcare robot and let the robot sweep the streets in at least 100 years, and it is too early for us humans.

Moreover, there must be a process for replacing human work with robots, and if this process is not handled well, it will cause world turmoil.

Do you think that those who do low-level manual work have not received a fair education, and now robots are going to run over and take their jobs, do you think they are happy?

"However, the direction is correct, and this kind of research is naturally done as soon as possible." Yuko is still holding on.

……

Donghai No. 1 Middle School, the fifth floor of the audio-visual education center.

Thoughts temporarily broke free from the memories, and Yuko sighed.

I don't know how many times similar arguments happened when Yuko was growing up.

After recalling all this mess, Yuko was also a little tired, and she picked up the scarred robot doll.

This doll was given to Masao Sakura by the community chief after Sally's death. Yuko was Sally's only friend during her lifetime, so they thought about it and returned the doll to Yuko, which was also Sally's last memorial to this world.

On the heart of the robot doll, there is a red heart-shaped blood stain, which is supposed to be left by Sally.

Yuko lay on the bed, gently kissed the heart-shaped blood stain with her lips, and then held the little robot in her arms and whispered softly, "Sally, please give me the strength to hold on......"
