At the end of the 19th year of the crisis era, Chen Xi ended his second hibernation.

After two years of development and breakthroughs in computer technology, brain-like intelligence has also ushered in explosive development.

In the laboratory, Chen Xi saw a bionic robot similar to a real person, holding a needle and thread in its hand, it was actually embroidering, and it seemed that it was still a traditional skill - Suzhou embroidery.

This is a brain-controlled robot.

He commented excitedly: "Fluent movements, like a clever weaver, if the precision is high enough, can you complete the trauma suture surgery independently?" ”

"What else can it embroider?"

The engineer said regretfully: "For the time being, I can only embroider, and there are only two or three fixed styles." ”

"The movement of brain neurons is so complex that even with the help of analytic cameras and supercomputing, it is extremely slow for us to compile the simulated neurons and crop the neuronal movements that are not related to the desired behavior."

"The PDC doesn't allow us to recruit volunteers on a large scale for experiments, they are worried that the human mind will be exposed, and there are unfounded worries that this group of bastards is hindering the progress of technology!"

"It's okay, it's okay, take your time..."

Walking around, Chen Xi found a fun thing, it was a rotatable cannon, and the person who controlled it wore the same helmet as the analysis camera, but this helmet did not have a supercomputer to match it, but if it was combined with cloud computing...

"Boss, that's someone from the military."

The engineer scolded angrily: "Those bastards have taken up our technical resources and equipment, and they want us to develop new weapons for them!" Call us slaves! ”

Chen Xi nodded to show that he understood, "I will protest." ”

Looking at the helmet for a moment, he asked, "The principle is to use the analytical camera to scan the human brain and direct the cannon to act accordingly after detecting specific neuronal movements?" ”

"Yes." The engineer affirmed.

"With the advent of the analytic camera, there is no secret to the movement of neurons in the brain, and we can find out the neural code that is unique to a certain behavior, that is, the order and relative position of tens of thousands, or even hundreds of millions of neurons in the brain."

He pointed to a camera equipped with a supercomputer in the distance, "The experimenter first has to use that thing to activate and use the neuronal instruction set of the smart weapon, which is not universal. ”

He then pointed to the helmet on the experimenter's head.

"We call this thing a control helmet."

Chen Xi thought to himself, a very apt name.

"According to the pre-obtained neuronal instruction set, the helmet only scans part of the brain, and when there is neural movement in the scanned area, the microcomputer will compare it with the neuronal instructions recorded in the chip, and as long as the similarity exceeds 90 percent, the helmet will send a signal outward to control the intelligent weapon to attack."

"Neuronal instructions?"

Chen Xi pondered for a moment: "The problem encountered is the speed of the comparison between the neural movements of the brain and the neuronal instructions, right?" ”

To put it simply, the latency is too great.

"Yes, the neuronal instructions are too large for ordinary chips to compare in milliseconds, but with a mainframe computer, the cost of weapons will soar tens of thousands of times, which is too expensive."

Chen Xi felt strange and asked, "Do they want to make individual weapons?" Do you need individual weapons in space warfare? ”

Future warships must be equipped with state-of-the-art supercomputers, and it can be said that it is easy to allocate computing power to support the operation of intelligent weapons, and even supercomputers can correct the small delay in data transmission by predicting.

The engineer shrugged his shoulders and said helplessly: "Maybe it's used to deal with humans, in fact, I prefer to use neural signal translation technology to create individual mechas." ”

Chen Xi: Hehe, I want to make a game helmet.

"Their idea is unrealistic, the huge control helmet contains liquid helium, and the liquid helium-soaked superconducting material needs a lot of electricity to generate a strong enough magnetic field for NMR."

"Wired power transmission is not realistic on the battlefield, while wireless power transmission is too much loss in the transmission process, with the current technology, more than ten meters away from the power transmission tower, the helmet can not get enough energy for nuclear magnetic resonance."

Chen Xi smiled: "This may be solved by Dr. Wang Miao's room temperature nano superconducting materials, with it, radio transmission is not a problem, and the volume and weight of the helmet can be reduced while maintaining functional integrity." ”

"It's difficult, I haven't made progress for several years..."

……

One night, Chen Xi admired the stars in the night sky as bright as the sun on the roof of the Shuguang Building.

It was a high-power nuclear fusion reactor experiment at an altitude of 30,000 kilometers, the engine of a future spacecraft, and the presence of stars meant that the experiment failed.

Thanks to more than two dozen experiments, the average temperature on the Earth's surface has risen by a full degree Celsius, and if the experiment continues, the blue star will sooner or later become a steamer for the hot dead.

Basking in the sun with sunglasses, the bright stars were still a little dazzling, at this time, Chen Xi suddenly thought of something, operated on the screen in front of the wheelchair, and let it sneak back to the office with him.

He turned on his computer and searched for a map of the solar system.

When writing the script of The Wandering Earth One, he showed Tomoko a plan to be invalidated: the purpose of your Trisolaran's invasion of the solar system is to get a new home, then I will turn the solar system into a purgatory that is less suitable for survival than the Trisolaran galaxy - using a planetary engine to push Mercury into the sun, which is a copy of the Rediaz plan.

But unfortunately, humans cannot build enough stellar-class nuclear bombs, nor can they have planetary engine technology.

Chen Xi found Halley's Comet, climbed through various papers, learned about its orbit, and calculated how much force it would take to push it into the sun.

After feeling that the future human civilization has the ability to push Halley's Comet, he simulated what would happen when Halley's Comet fell into the sun in the relevant software, and the result was naturally regrettable.

Halley's Comet is only 10 trillion tons, 1/30 million of Mercury's mass, and its fall into the sun has caused extinction to Mercury at most. ”

Chen Xi's muttering made the three-body person who was watching him tremble in his heart, praying that he would not think about it along this line of thought!

After scaring the three-body people and paving the way for himself to break the wall Rediaz, Chen Xi went to rest.

In May of the 20th year of the Crisis Era, the Thought Steel Seal Technology appeared, which was exactly the key technology that Chen Xi needed, so he went to the Faith Center in the Beautiful Country.

Seeing the wall-facing people from his own country, Wu Yue, who was lost in despair, asked: "Dear Mr. Chen Xi, are you also here to seek firm faith?" ”

Chen Xi shook his head: "No, I'm a defeated hedonist who doesn't even want to resist, I don't need any firm belief in the victory of mankind, because this is distorting and violating the freedom of my thoughts, this is trampling on human rights!" ”

Is it? No one will believe you.

Wu Yue left the Center of Faith.

Seeing the model couple, Chen Xi smiled slightly: "Mr. and Mrs. Hines, good afternoon." ”

Looking deeply at the hidden young man, Hines retracted his gaze and said, "Mr. Chen Xi, if you have anything to say, I will try to help you." ”

Because you and I are the same people.

"Okay."

Chen Xi put up two fingers: "There are only two things, one is that I hope you can give me the only simulated brain that your wife assembled with 100 billion microchips, anyway, because of the progress of computer technology, it should be of little use to you, right?" ”

"But for me, it's important, and my brain-like intelligence is still short of a complete analog brain as the main brain."

Hines looked at his wife affectionately: "Keiko? ”

Keiko looked at Chen Xi: "Is this part of the plan?" If yes, I'll give it to you. ”

"Yes, of course, that's what the AI initiative needs."
