700 years later

Dou Yu wondered if he had just dampened Cheng Zhang's enthusiasm.

He tried to comfort him, but he couldn't find anything to say. After all, the facts are here. Even if human beings disappear, he can't create a group of the same kind for Cheng Zhang.

"Actually, it's not as bad as you think," Dou Yu said, "Actually, it's not completely extinct."

"Yes," Cheng Zhang could only say, "and you, the last human being in this world."

"Am I human?" Dou Yu was stunned suddenly. He thought for a while and asked Cheng Zhang this question, "Actually, not necessarily."

Cheng Zhang was taken aback: "What's wrong with you? Are you okay?"

"It's just an idea that came up," Dou Yu shrugged. "Actually, there is no way to prove this thing. Pain, emotion, and thinking patterns can all be imitated by artificial intelligence, and nothing is irreplaceable. Then I have Maybe it's just a high-level experiment that imitates human beings, even I do the same thing every day, more robots than robots."

Dou Yu, who grew up in the era of artificial intelligence, has had the most contact with artificial intelligence since he was a child. He has more experience than Cheng Zhang.

"I once made a robot," Dou Yu recalled, "actually, the process is not complicated. I selected the highest quality artificial skin and organs, input every expression and body language of human beings, and built a neural network. But later, I destroyed her, the destruction of intelligent robots requires evaluation, but I don't need it, I have this authority."

"Why?" Cheng Zhang asked, "It was so painstakingly finished and then destroyed."

"Because I made myself a mother." Dou Yu said calmly, and he clearly saw Cheng Zhang take a deep breath in surprise, "My mother is dead, I have nothing to do, turn on the computer, and write what I can remember. I wrote everything about her mother, debugged almost the same voice line, and when I made her, I thought it was exactly the same as my mother. But I was too scared, I typed out every line of her code, I Knowing all her feedback, I knew what she was going to say before she even opened her mouth. I even knew which leg she would take first when she went down the stairs, and the little finger of her right hand would slightly lift up when eating utensils. Think, I know best, she is a complete robot, but she thinks she is a mother, but what am I? Am I also..."

"On the day I sent her away, she said a sentence to me. That was the only sentence that was not written in the program. That was not the algorithm I wrote."

"She said: 'I hate you.'"

Cheng Zhang wondered if what Dou Yu said was too advanced for him, and he should ask for preschool education.

What a strange ethics classroom this is!

What's more, Dou Yu is really serious about giving him science popularization, instead of the miserable little white flower crying about the tragic childhood of losing his mother. He not only has to attend class, but also demonstrates with examples, and finally leaves the class assignment: Is Teacher Dou Yu a human being?

Cheng Zhang wants to go to his tutor and kneel down and sing forgiveness. He doesn’t know how expensive papers are when he is young. He doesn’t want to time travel anymore. He wants to go back and write his graduation thesis, contribute to food engineering, make cakes in the laboratory and distribute them to his classmates. Either option is better than the present.

Not long after he came to this world, he saw Dou Yu, and he saw it on human TV.Then as soon as they met, Dou Yu deprived him of his citizenship, because only Dou Yu is the only human being in the world, the last treasure.If even Dou Yu is not human, then he...he doesn't know what to do.

"Then I don't know how to prove it." Cheng Zhang bite the bullet and said, "What else can I do, dissect you, pull out the wires in your organs, and tell you when you are about to die, oh my god It really is a robot, you see the wire is still sparking!"

……

Dou Yu said: "You are really abnormal, I think you are indeed a human being."

Cheng Zhang was so wronged that he was actually called abnormal by a man who made a mother manually.How old was Dou Yu at that time, less than ten years old, right?What kind of action is this? If he was born in Cheng Zhang's era, he would be a proper gifted child and would enter the juvenile class.

Or maybe, Cheng Zhang thought, seeing Dou Yu's incomparable proficiency in computer technology, he also has the opportunity to become a senior code farmer and become bald at an early age.

"I don't think you are an artificial intelligence," Cheng Zhang said, "Although you always say that human beings can be replaced, you can't tell the difference, but you destroyed it in the end. I don't think it's just because of what you said, you You can deduce its every move, but because you know that it is not true. You have experienced the truth before, and you cannot accept even an identical substitute. Artificial intelligence will not choose this way, and it will not be able to write it out. It's a human emotion."

"I used to go to a class in the philosophy department of our school. Once, the teacher was talking about "Utopia", saying that in Plato's conception, human beings are creatures living in caves, and they can only watch from the cave walls. A projection of the real world, thinking that is the real world, until they come out of the cave and see the reality. Once you have seen the sun, you can no longer pretend that you have not seen it."

Dou Yu didn't quite understand: "The sun?"

In the thousands of years when human beings ruled the world, human beings, shameless creatures, sang praises to themselves every day, and praised themselves in different ways. The essence of the universe, the primates of all things, completely disregarded how much harm human existence caused. By the way How many species have been destroyed, and they are clamoring to protect the environment and save the earth.The earth has never ended, and the end is their own.

But people are such creatures, illogically self-righteous, and in the end, they disappear because of this.They have given so much meaning to their lives, they can no longer accept being looked down upon by other lives, and have no value for their own existence.What humans can do, robots can do, and they can do better. In addition to technology, even the art that humans are proud of is nothing more than a combination of data clouds.As long as there is a large enough computer, all poems, novels, scripts, and music can be arranged and combined. The things you find in the thousands of threads have long been stored in the database.what can they doJust live.

There is nothing wrong with being alive. Of course, people are also driven by the desire to survive. Most people are just playing a dispensable part of society, eating, sleeping, going to school, working, getting married, having children, and dying. Of course, living is just to live , not so much time to think about meaning.If you tell any ordinary person that from tomorrow onwards you don't have to do anything but enjoy yourself, they will probably be happy.But for 700 years, it has been like this, but it has become torture.

"I seem to understand now why humans choose to disappear. This is not the decision of an individual, but the unconscious choice of the entire species. Because even if they have a little curiosity to understand what their ancestors did, they cannot Pretending not to have seen it, I can't bear to continue such a worthless life, being watched and pampered by robots like pets. What I'm wondering now is..." Cheng Zhang suddenly couldn't speak.

What he wondered was why Dou Yu chose to live, and Dou Yu knew it all.

He didn't say it, but Dou Yu understood.

"I was just joking with you just now," Dou Yu said, "Of course I know that I am a human being, and I am the last human being in the world."

The last itself is the last meaning of his existence.

Even if he had doubts before, until now, he has confirmed that he is really human. In order to confirm this fact, he has made many painful attempts.And at this moment, it is because, if he himself and even the world are really a set of codes, then in the extremely precise algorithm, there will be no strange bugs or irrational existences like Cheng Zhang.

"I'm tired." Dou Yu turned off the projector and announced, "I don't want to talk about it today. You keep interrupting my progress. I was supposed to talk about driverless cars today."

He obviously prepared very carefully, and even wrote the outline of the lecture!

When unmanned vehicles first started to operate, they were not popular and the technology was immature. They had accidents and killed people.Even if it can be guaranteed that there will be no accidents in the future, the residents of the trial site are still hostile to unmanned vehicles, and throwing stones at the vehicles is already the lightest treatment.However, it still develops rapidly regardless of people's will, completely replacing human drivers within a few decades. down to zero.Human beings have found that areas without human participation are the most stable and safe.

This is a tiny part that becomes the beginning.

Dou Yu angrily transferred the information to Cheng Zhang: "You can see the history of the rise of unmanned vehicles for yourself! At this speed, I'm going to talk about the year of the monkey."

"That's good," Cheng Zhang said, "I'd like to listen to you slowly."

"I'm not willing yet." Dou Yu stood up and pushed Cheng Zhang away, "I'm going to rest!"

That's what he said, but Dou Yu has already started thinking about what to tell Cheng Zhang tomorrow.This is not a normal so-called class at all, just find a topic, use it to continue chatting, and say anything, as long as someone can talk, chatting wildly, and talking without purpose.He couldn't think of what Cheng Zhang would say next, and he didn't know what surprise would happen tomorrow.

These are all unplanned things, which confuse and amaze Dou Yu.That old world should be something he knows very well, and the electronic data can be retrieved at any time, but he did not do this, preferring to piece together the real life 700 years ago in the words of others.Like Cheng Zhang, or...

Pirate Captain.

"How was class today?" Dou Yu opened the communication software and saw the pirate captain asking him.
