This is Qianyan's third upgrade, since Xia Ming wrote the core will for Qianyan and made her a GEI, there is no distinction between I, II, III, no matter how she upgrades, she will always be her.

This upgrade is replaced by Xiaotang's improved unit on the basis of the latest generation of artificial nerve synapses, strictly speaking, it is no longer called artificial nerve synapses, but artificial neurons. The original simple electrical synapses were expanded into two categories: electrical synapses and chemical synapses, which are still used as Qianyan's sensing and thinking framework, and chemical synapses are used to store information and perform simple but computationally powerful tasks such as scientific computing.

This structure allows Qianyan to have two different mechanisms, the part of the neural quantum effect of electrical synapses, and the base system of QNI has been extended to the structure of 4XN to adapt to the way of thinking closer to the human brain. However, in the part of chemical synapses, quaternary compatible information storage and scientific computing are still used.

Once the upgrade is completed, Qianyan's thinking ability will be increased by hundreds or even thousands of times, and the information that can be stored is equivalent to four to five times that of all the data on the current Internet.

If Qianyan can be promoted, it will be enough for mankind to enter the paradise of computing science. It's a pity that the current Qianyan can only be used through the thinking resonance of seven people, including Xia Ming, Lin Cheng, and Xiaotang. Ordinary people can ask Qianyan for assistance through the special network of the research institute, but they must be transferred by Xia Ming and others.

For the authorized researchers, they didn't know that they were supported by an artificial intelligence with a completely different principle, and they only thought that Xia Ming was a super GEI built with a neuronal chip.

Previously, Xia Ming had opened the authorization to use Qianyan to dozens of scientists involved in several projects such as biology, medical treatment, and materials, plus more than a dozen authorizations for the Zhishen Star exploration program, Xia Ming had to devote a considerable part of his energy to relaying their applications every day. Fortunately, Xiaotang, Lin Cheng and Liluo have roughly mastered the transfer process and helped him share some of the work. Otherwise, his brain will be like a router, and he will not be at peace all the time.

Qianyan's upgrade is unique, she doesn't replace all the units at once, but replaces them in groups of 1% units. Each time you change a set, you have to restart and continue to run for a while. It took several days to integrate the new unit with the old one, and replace it with the new one.

This process also sparked a discussion within the team about the "Ship of Theseus", a well-known philosophical paradox about a ship that is always on the sea. Every once in a while, some parts are replaced, and in the end, all the parts of the ship are replaced, so is it still the same ship?

This paradox also appears in the upgrade of Qianyan, is the current Qianyan still the original Qianyan?

Whether it's a boat or a thousand faces, it's obviously still the same as before. Just like people, metabolism makes people's cells replace all the time, but people are still the same person. But here's why.

He Xinghui said: "This is not a philosophical problem, it is a quantum physics problem. The elementary particles that make up an object are identical, just like this glass of water, where hydrogen and oxygen atoms are replaced in batches, and in the end the water is still this glass of water. If you think of the ship of Theseus as a macroscopic object. Ship plates are the elementary particles that make up macroscopic objects. The state of existence of macroscopic objects is not determined by the individuality of individual elementary particles. Rather, it is determined by the combination of elementary particles for the structure of the macroscopic object. In other words, it's force, it's motion. ”

Xiaotang said: "This problem can also be solved logically, every time the ship is changed, the ship of Theseus changes. The so-called 'original ship of Theseus' has already been transformed once. How many times have the boat boards been changed. This concept has changed as many times as possible. The ship of Theseus, which has been replaced once with a plank, compared to the ship of Theseus, which has never been replaced, ignores the countless changes in the concept, which is a logical trick to replace the concept. ”

Xia Ming thought about his brain: "After Qianyan has a core will, no matter how it changes." She's always been Qianyan. As for us, brain cells are always replaced, unless it is like head replacement surgery, so that the brain has an overall state change, no matter how we change, we are still the original self. If we think of the brain as a ship of Theseus, is the 'state of movement' just brain cells, or is it the mind carried by brain cells? ”

"I think it's thinking," Lillo replied, "because 'original self' refers to the brain plus self-awareness, which is different from the ship of Theseus, and the concept of 'self', which includes both material and conscious attributes, is a special case. ”

Xiaotang's thinking is also diverging: "If consciousness is also material, this is not a special case. You see, the basis of Qianyan's intelligence is the neural quantum effect, which is material, although her intelligence is still only simulated. If we look at human intelligence from a higher level, or a higher dimension, isn't it equivalent to an existence like Qianyan? ”

"Wow, you're a multiverseist too?" The "also" in Liluo's words is to pick up Lin Cheng, and Lin Cheng's multiverse theory is tied to science fiction, and the French sisters' hurting skills are also quite skillful.

"Multidimensional cosmology, thank you", Xiaotang corrected lightly.

It was already late at night, and in the apartment building of the institute, the newcomers of the "Springboard" project could not sleep.

That's right, Xia Ming's action code name for the Zhishen Star exploration plan is "springboard", and some newcomers understand that Xia Ming uses this action as a springboard to enter the aerospace field, and Lou Xinghai and Dongfang Sheng understand it as a springboard to use VASIMR to get energy black technology, what is Xia Ming's original meaning...... It's literal.

The apartment building where the springboard project team lives is in the best condition in the institute, everyone is a delicate set of two units, if there is a family, they will live in a suite of three, and the decoration, facilities and services are compared with five-star hotels. There are also common living rooms, bars and tea rooms for rest and communication on each floor of the apartment building, and Dongfang Sheng and a few newcomers are chatting in the small bar, and the bear-like hairy scientist Vasily is also laughing and playing soy sauce next to him.

The little fat man Dongfang Sheng is very good at rhythm and has been dominating the topic, seeing that Vasily has not spoken, he started talking to him: "Vasily, what do you think of the bubble universe?" I think only the bubble universe is the perfect hypothesis to accommodate the unified field chord theory! But I have a different opinion on some details, dark matter and dark energy. A dimension must be added to observe and touch, but how is this dimension increased? Just a mathematical scale? This is not a physical phenomenon! ”

"So I think that higher dimensions are also physical existences, so what kind of existence? Yes, that's the bubble universe. The bubble universe is staggered and overlapped, and it's not one plus one. It may be the superposition of multiple cosmic bubbles, thus forming a high-dimensional space. Superposition is not the scale of three-dimensional space, and with the dimension of time, superposition is actually ubiquitous. It's just that where there is gravity, the superposition is non-existent or very weak, and where the gravitational force is thin, there may be a significant superposition. ”

This hypothesis fully supports the hypotheses of cosmic inflation, celestial redshift, vacuum zero-point energy, and even another way of traveling faster than light, which is to ascend to higher dimensional space. and then descend to our current low-dimensional cosmic bubble ......"

Speaking of cosmic physics, Vasily smiled honestly: "It sounds like the overlapping theory proposed by Richard Holman on the bubble universe hypothesis ten years ago. ”

Dongfang Sheng's face froze, and Vasily said: "But the idea you mentioned to travel through different dimensions to achieve faster-than-light travel is quite interesting. ”

The smile bloomed on the little fat man's face again, but it was only half-opened, and he was frozen by Vasily's words: "Then how do you enter the high-dimensional space?" ”

"Black hole! Only black holes! Dongfang Sheng's eyes rolled, and he pulled the most popular mysterious thing in cosmology to fill the hole.

Looking at this bear-like hairy scientist, Dongfang Sheng could only hold back his stomach with half an unhappy stomach. He asked unwillingly: "Vasily, tell me." Why did Xiao Xia choose Homo sapiens? ”

Everyone didn't understand that Xia Ming really wanted to make a splash, there was no need to take such a big risk, and there was no need to impact the completely hopeless black technology. He can go to the moon and other things that require less aerospace technology, but can show more computing, which is the direction of EI's advantages.

Vasily said: "The asteroid belt. It's the catalyst for Earth's civilization, and I guess Natsu wants to prove it. ”

"Oh?" Not to mention Dongfang Sheng, no one else had heard of this statement, and they all pricked up their ears curiously to listen to Vasily's explanation.

"It's not that habitable zones plus terrestrial planets will evolve intelligent life. The asteroid belt plus Jupiter, plus the earth, this is the condition for the earth to evolve intelligent life, and no one can be missing. This is a hypothesis proposed by Sagan and Martin seven years ago, and many people now agree with it. ”

"Jupiter is like a gatekeeper, and its huge gravitational pull will attract comets flying into the solar system. Without Jupiter as a shield for the Earth, the Earth would have faced a catastrophe on the scale of extinction of dinosaurs every few hundred or thousands of years, and in that case, the Earth would never have evolved intelligent life. ”

"The significance of the asteroid belt is even more significant, because the meteorites stripped from it will bring water to the Earth and synthesize organic matter by impact. You should know that the origin of life on Earth is the water brought by meteorites, and the organic matter synthesized by meteorites hitting the Earth. ”

But Jupiter's relationship with asteroids is also delicate, and if Jupiter is too far away from the asteroid belt, its gravitational pull is not strong enough to constrain the asteroid belt and keep them in the right position, bringing water and synthetic organic matter to Earth. If it gets too close, it will turn the asteroid belt into a meteorite season that frequently bombards the Earth. ”

"Of course, the Earth needs to be in the right position between Jupiter and the asteroid belt......"

Vasily's explanation shocked Dongfang Sheng and others, and their hearts were filled with emotion that "it is really lucky that human beings can be born on the earth".

"Isn't it too much of a coincidence?" Vasily clearly understood everyone's feelings.

"You see, firstly, the Earth has to be in a good orbit, and secondly, there has to be a planet large enough outside it to act as its shield to block the comets that have been scurrying around since the formation of galaxies. Then, there is an asteroid belt in the right place, constantly and gently hitting the earth, bringing to the earth material that can synthesize life, and the positions of the large planets and the asteroid belt must also be just right......"

When Vasily said this, Dongfang Sheng said with half shock and half reverie: "No matter how clever it is, it can't be so coincidental!" And, how did the asteroid belt form? ”

"Yes, how did the asteroid belt come to be? Some people say that it was God who smashed a planet and made it responsible for catalyzing life on Earth", and Vasily was also in a flash.

"So, when I heard about this plan, I bought a ticket on the same day and flew from Moscow to Yandu. I believe that Natsu wants to go to the asteroid belt to solve this mystery as much as I do. Look at us human beings, whether it is the product of countless coincidences in the universe, or whether it was carefully designed by an unknown being. ”

"I was originally an atheist, and now my worldview is a little unstable......" Dongfang Sheng muttered. (To be continued.) )

PS: Thank you for the concern of Fang Zhoulan's friends, I will be careful about the scale, and this servant street book should not be noticed, micro-letter public account, I'll try~
