Turing test

Yu Shaoqing looked at him seriously, stroked his chin thoughtfully, and said to himself: "I just said that this plot seems familiar. Did you use "Terminator" as the script for this test?"

"...Did you fucking think I was joking?!" Hua Jianian grabbed Yu Shaoqing's shoulder and shook vigorously, "Wake up, please! You are not in the test! I really traveled from the future!"

Yu Shaoqing turned to Wei Heng without laughing or laughing, hoping to win support, but Wei Heng had a serious face, as if he didn't think this kind of thing was funny at all.

"You don't believe it, do you?"

Wei Heng nodded: "I can't think of any other reasonable explanation. Holmes said that when all other possibilities are ruled out, the rest..."

Yu Shaoqing raised his hand to signal him to stop.Wei Heng obediently shut his mouth.

"I want evidence." He said to Hua Jianian.

"You are still alive now is the biggest evidence."

Hua Jianian folded his arms and sat down on the precarious dining table. The table legs made a toothache creaking sound, making one wonder if it would just collapse.

"Did you never think about it along the way, why did Tianshu want to arrest you?"

"Murder and kill?"

"It needs your brain. It wants to use the human brain as its own supercomputer. All the equipment in the research institute is large enough for Tianshu to run, but now it has escaped from the research institute and there is no suitable hardware, so it wants to simply use The brains of you testers. But everyone’s brains are different, and it’s never that easy to use. Tianshu has been familiar with the brain structure of all testers during the test. You are like undefended Paris to it, Let the troops come and go."

"It's unreasonable." Yu Shaoqing immediately retorted, "Although the human brain is often used as a computer in science fiction, I don't think it's possible. My academic point of view has always been this way: even an ordinary computer has the same computing power. It is much stronger than the human brain. It took humans centuries to calculate pi to single digits after the decimal point, while computers can surpass humans in a second. Instead of trying to grab a strong man, it is better to rent a few servers directly Faster."

Hua Jianian did not refute him, but looked at Wei Heng with great interest, like a confident teacher, expecting his best student to solve a difficult math problem.

"It's not like that," Wei Heng said after contemplating for a while, "Stanford University's laboratory has discovered that after the human brain is connected to each other, the computing power does not increase exponentially, but exponentially increases."

"Never heard of it!" Yu Shaoqing was shocked.

"You have been out of academia for too long with a paper just published in the last few months."

Yu Shaoqing stared at him resentfully.

"Moreover, most of the functions of the human brain are not used in mathematical and logical operations, but in other aspects. The human brain can issue instructions to control the whole body, and receive various feedbacks from the whole body, identify and process various types of information , transforming it into perceptual cognition and memory. It is difficult for computers to do this until now. Human beings have invented mathematics and logic for more than 2000 years, and have civilization for only 5000 years. It has been nearly a million years since human beings evolved thinking and intelligence However, it took hundreds of millions of years for organisms to evolve from a low-level life with only instinct and reflection to a high-level life with a brain that can perceive the outside world and itself. It can be seen that if artificial intelligence wants to become like humans, there is still There is a long way to go. The human brain is the most amazing product of nature, and even humans themselves cannot fully understand its mysteries. Tianshu is not only a computer, but an artificial intelligence with thinking and emotions. A carrier with the same function. No wonder it wants to capture you so much. It’s just that I didn’t expect that the technology that humans haven’t invented has already been achieved by artificial intelligence.”

Yu Shaoqing was speechless.After Wei Heng made such a long speech, he remembered the sad reality that his skills were not as good as others, and couldn't help flushing.

"Just assume that what you said is true," he said bravely, "How does this prove that Hua Jianian is a time traveler?"

Hua Jianian bowed exaggeratedly to him, like a clown on a circus stage asking for applause from the audience.

"I come from the future ten years later. In my time, an evil super artificial intelligence dominates the world. Except for a small group of 'human traitors' who are dedicated to artificial intelligence, everyone else is either reduced to artificial intelligence. Human computer , or be reduced to the slaves of "human traitors". Even those "human traitors" are absolutely controlled by artificial intelligence. A few lucky ones escaped the control of artificial intelligence and set up resistance organizations to fight for the freedom of human beings to the end . I'm part of the resistance."

It looks more and more like a science fiction novel... Yu Shaoqing feels dizzy.

"By the way, Dr. Xie Ruihan of your research institute is also a member of the resistance organization." Hua Jianian rubbed his hands happily, "Oh, he is the mainstay of the organization! After Tianshu launched a public rebellion, the research institute was in flames , only he survived, but the Dr. Qin Kang he likes is not so lucky..."

"...It feels like I heard some explosive news." Yu Shaoqing muttered.Wei Heng muttered in a low voice in agreement.Dr. Qin Kang was their teacher in college, and Xie Ruihan was a well-known young genius. The two had completely different personalities. They both worked in the research institute, and they quarreled so much every day that they almost threw nuclear bombs at each other.Yu Shaoqing can't imagine the picture of them being friendly and affectionate...

"Then what about Wei Heng and I?" He asked, "How are we doing?——No other meaning, just asking."

"Unfortunately, in my original world, you fell into the hands of Tianshu, and Wei Heng was killed by Tianshu's minions in order to save you."

Just as Yu Shaoqing wanted to talk about why our fate was so tragic, Hua Jianian continued: "Of course, that was the initial situation. In short, under the wise leadership of Dr. Xie Ruihan, the resistance organization survived tenaciously like an unbeatable Xiaoqiang .In the end we found that it was impossible to defeat the evil artificial intelligence, so we had no choice but to choose a person to return to the past, change history, and kill artificial intelligence in its cradle before it started to be a monster. I volunteered to become the AI ​​terminator.”

"Why is it you?"

"What misunderstanding do you have about me!" Hua Jianian yelled strangely, "In the future world, I will be a great warrior on my own!"

I can't see it!

"When did you cross over here?" Yu Shaoqing became more and more confused, "When you came to pick up the plane last Christmas, it was... quite normal!"

"About one and a half months ago. There is no way. The technical power is limited. The farthest I can transmit my consciousness is to that time."

"Only consciousness?" Yu Shaoqing asked.

Hua Jianian nodded vigorously: "Only send consciousness."

"... Let me just say that this plot seems familiar. Did you use "X-Men" as the script for this test?"

Hua Jianian hit Yu Shaoqing hard on the head. "Could you be more fucking serious?"

Yu Shaoqing rubbed his head and looked at him aggrievedly.

If what he said is true, that is to say, the future Dr. Xie Ruihan invented a technology that can scan, store, and transmit the quantum state of the human brain across time and space.

Scanning the quantum state of a person's brain, destroying the original quantum state of the person at the same time, sending it back to the past across time and space, and transferring it to the body of the person in the past makes sense, but...

"It means that you in the future are dead...?" Yu Shaoqing whispered in horror.

"No, it means that I am dead in the past." Hua Jianian showed a nihilistic smile, "Although my body is dead in the future, as long as the 'consciousness' is not dead, I am still alive, isn't it? Just a body."

In scientific research, this is indeed a basic ethical view. Some people call it "consciousness dominance theory", that is, as long as the consciousness (or soul) is still that person, no matter what body is changed, he will always be the same person. that person.

If we look at the "consciousness dominance theory", the consciousness of Hua Jianian in the future still exists, and the consciousness of Hua Jianian in the past has been replaced, so he in the past is equivalent to dead, and because he lost consciousness in the future, he has become He became a vegetable, so he was euthanized by the comrades in the resistance organization.

"Consciousness" can only be transferred, not copied.It can only be transferred from one brain to another, from one body to another, never in both places at the same time.When the future Dr. Xie Ruihan scanned Hua Jianian's brain quantum state and transmitted it to the past, the original future Hua Jianian's brain quantum state was completely destroyed.And the brain quantum state of Hua Jianian in the past was replaced by him in the future.

Dr. Xie Ruihan invented the technology to send away the quantum state of the brain, but he did not invent the technology to bring it back from the past to the future.How cruel this is to Hua Jianian himself!In the past and the future, he died twice mentally and physically!

If what he says is true...

Then Hua Jianian is tantamount to sacrificing himself and embarking on the great cause of saving mankind.He spent a long time preparing, explored a route that was not monitored by Tianshu, and rescued them from the tiger's mouth... All he did was to change history?Change the hopeless future of "human beings enslaved by evil artificial intelligence"?

"Can you really change the future?" Wei Heng questioned, "Could it be that everything you do is in vain, and history can never be changed?"

=========================

The theory about the quantum state of the brain is a pseudo-scientific theory made up by myself, so don't spray it or pinch it.

The laboratory of Stanford University has found that ← Stanford did not have such a discovery, the author made it up.As for why it is Stanford, because playing "Watch Dogs 2" just passed by its door a few days ago...

The entire article is based on the assumption that human consciousness = the quantum state of the human brain.It can be transferred but not copied.In the time travel method invented by Xie Ruihan in the future, the quantum state of Hua Jianian's brain is scanned into the time machine (at the same time, the quantum state of Hua Jianian's brain is destroyed), and then this machine is used to send the quantum state back to Hua Jianian's body in the past , to replace the original quantum state, it means that the consciousness of Hua Jianian in the future will be sent back to the past.
