Chapter 171： digital life

Li Yi was a little surprised, and the person who asked him the question was Zhou Wenhui.

Li Yi nodded and looked at Zhou Wenhui, and said, "Well! What's the problem with you?"

"Mr. Li, artificial intelligence with subjective consciousness, learning ability, self-optimization, and evolution ability must be very strong. Its growth can definitely surpass that of human beings, which is equivalent to creating another kind of life, so how to be sure that it will not get rid of human beings. Control, or if it is malicious to humans?" Zhou Wenhui stood up and looked at Li Yi and asked solemnly.

"That's a good question!" Li Yi nodded in approval with a smile, and then explained: "Artificial intelligence with 'subjective consciousness' does belong to another kind of life, and they can be called: digital life, this species will inevitably The pursuit of 'freedom' and 'evolution' is characteristic of every intelligent species, so we cannot predict its movements, nor its future."

"Once the species of digital life appears, it must be advanced and dangerous. Its intelligence is like the status of humans and other species on the earth. It is difficult for us to understand its intention. Therefore, when developing artificial intelligence , We have to be very careful and use technology to create controllable artificial intelligence belonging to human beings, rather than uncontrollable digital life." After a pause, Li Yi added.

"How can I confirm that what is being developed is controllable artificial intelligence, not digital life?" Zhou Wenhui then asked.

"Sit down first! Explaining this question requires knowledge of a large number of disciplines, so I will briefly introduce a few technical ideas." Li Yi smiled and motioned Zhou Wenhui to sit down.

Zhou Wenhui nodded, and after sitting down, she looked at Li Yi with bright eyes, waiting for the answer.

Li Yi turned his back to the blackboard, picked up the chalk, and wrote a mathematical formula of 1+1=2 on the blackboard.

"Does everyone know this formula?" Li Yi turned to look at everyone and asked.

The students frowned, not understanding what Li Yi had to do with the mathematical formula that all elementary school students knew, and what it had to do with artificial intelligence.

"This formula is called Peano's axioms, also known as Peano's postulates. It is a system of five axioms about natural numbers proposed by mathematician Peano."

"According to these five axioms, a first-order arithmetic system, also known as the Peano arithmetic system, can be established."

"These five axioms of Peano are described in an informal way as follows: ①0 is a natural number; ②every definite natural number a has a definite successor x\', and x\' is also a natural number (the successor of a number) A number is the number immediately following this number, e.g. 1 is the successor of 2, 2 is the successor of 3, etc.);"

"③If b and c are both the successors of the natural number a, then b=c; ④0 is not the successor of any natural number;"

"⑤ Let S be a subset of the set of natural numbers, and (1) 0 belongs to S; (2) if n belongs to S, then n\' also belongs to S. A more formal definition is as follows: a Dedekind-Peano structure is Such a triple (X, x, f), where X is a set, x is an element in X, and f is the mapping of X to itself,"

"And meet the following conditions: x is not in the range of f; f is an injective; if x ∈ A and "a ∈ A implies f(a) ∈ A", then A=X. The set of natural numbers introduced by this structure The basic assumptions of: 1.N (set of natural numbers) is not an empty set; 2. There is a one-to-one mapping of a→a\' in N to N;"

"The set of images mapped by subsequent elements is a proper subset of N, in fact N\\{1} (or N\\{0});"

"A subset P of N is equal to N if it contains both elements that are not successor elements and elements that contain successors of every element in the subset."

"Proof of 1+1: The successor of ∵1+1 is the successor of the successor of 1, that is, 3, and the successor of ∴2 is 3."

"According to Peano's axiom ③, we can get: 1+1=2."

Without getting a response from the students, Li Yi turned around and began to write the answer with chalk, explaining while writing.

Just when the students almost understood the Peano axiom, Li Yi changed his words and pointed to this formula: "When designing the underlying architecture of artificial intelligence, we can borrow this formula and set 1 as artificial intelligence. The basis of the criterion, the other 1 is set as the environmental calculation of artificial intelligence, and the addition of the two fulcrums makes the public and private become, then the variable 2 is obtained, ... "

"Two criterion frameworks are defined, artificial intelligence learns through simulation, and will eventually revolve around the 1+1 criterion, stacking algorithms to obtain 'variables',..."

...

Li Yi eloquently explained the technical route of developing controllable artificial intelligence.

However, the students' eyes began to appear dazed, and various mathematical symbols, professional terms, impacted again and again, crushing their IQ.

Li Yi also seemed to have discovered this situation, and quickly stopped the technical popularization, and explained with a smile: "Controllable artificial intelligence can be realized through the setting of the underlying architecture of artificial intelligence, the construction of the ecological environment, and the control of the hardware system. Technology can make artificial intelligence evolve along the route we set from the very beginning of its birth.”

After speaking, Li Yi glanced at Zhou Wenhui, as if to confirm whether she could understand.

Zhou Wenhui nodded knowingly, as if he understood Li Yi's explanation.

"Okay, are there any questions? If not, I'll move on to the next content!" Li Yi asked with concern, looking around the students.

The students kept silent, didn't dare to ask questions, joked, and asked a question casually, and they wrote down a lot of incomprehensible things in the diary. Who would dare to continue to ask!

Upon seeing this, Li Yi smiled slightly and had no choice but to continue explaining the follow-up content of the course.

Li Yi was in the large amphitheater, during his first class.

The news quickly spread throughout the school, and immediately attracted the attention of countless students. One by one, students surrounded the large amphitheater, waiting for Li Yi, who was after school.

"I was almost able to report, but my hands are slow!"

"Sorry! I canceled it! Otherwise, I'll see the big guy up close!"

"Why hasn't get out of class finished yet! It's almost there!"

...

A large group of students gathered outside the teaching building to join in the fun, waiting for Li Yi to come out.

Li Wenxiu was also pulled over by his roommate. Several girls chatted excitedly and chatted endlessly.

"Wenxiu, I knew I would listen to you and report to artificial intelligence. Now I don't have to stand here and wait!" Zhang Xiaomin looked at Li Wenxiu and said regretfully.

Li Wenxiu rolled his eyes, it would be troublesome if he reported it!

"Wenxiu, isn't your boyfriend taking classes there? Let him post some photos! I want to see a recent photo of Li Yi! Isn't he handsome!" Zhao Yayu looked at Li Wenxiu and begged.

"The message has been sent long ago, but I didn't get back!" Li Wenxiu frowned and said angrily.

There seem to be a lot of photos of Li Yi in the phone, but I can't tell my roommates, this feeling makes Li Wenxiu feel very irritable.

"Let's go! Don't wait! He will definitely hide in the Academic Affairs Office and won't come out so early. Let's not wait here." Li Wenxiu suggested.

"Just wait and see! Class will be over soon!"

"The get out of class will be over in five minutes, so there shouldn't be any delays!"

Zhang Xiaomin and Zhao Yayu were reluctant to leave and persuaded them.

Li Wenxiu sighed helplessly and waited outside with her roommates. With what she knew about her brother, he would definitely not show up on such an occasion if he was too troublesome.

Sure enough, the get out of class bell rang for a while The students in the large lecture hall came out one after another, but could not find Li Yi's figure, he had already left through another special passage.

Li Wenxiu saw Zhou Wenbin and a very beautiful girl beside him, her face changed slightly, and she hurried forward to meet him.

"Wen Bin, why didn't you get back to me when I sent you a message? Who is she?" Li Wenxiu looked at the beautiful girl beside Zhou Wenbin vigilantly, felt a serious threat, and asked questioningly.

The roommates followed Li Wenxiu one after another, and looked at the girl beside Zhou Wenbin anxiously. They were both girls. They were all amazed by each other's looks and couldn't help worrying about Li Wenxiu.

"I handed in my mobile phone in class, and I will reply to you immediately. Didn't I follow you and told you that I have a twin sister! She is my sister-Zhou Wenhui." Zhou Wenbin explained and introduced.

Hearing this, Li Wenxiu blushed pretty, and immediately felt embarrassed.

"Little brother, your girlfriend?" Zhou Wenhui looked at Li Wenxiu with a funny look and asked with a smile.

"Well! She's my girlfriend - Li Wenxiu!" Zhou Wenbin quickly took Li Wenxiu's hand and introduced to the old sister.

"Sister Wenhui, hello!" Li Wenxiu said hello to Zhou Wenhui, and then introduced her roommates: "They are my roommates, Zhang Xiaomin, Zhao Yayu, Lin Shufang."

"Hello, let's find a place to sit! There are a lot of people here." Zhou Wenhui frowned and quickly suggested that she noticed a lot of people looking at her.

"Okay!" Li Wenxiu nodded happily, looking at Zhou Wenbin and waiting for his arrangement.

"I know it's a quiet place, I'll take you there!" Zhou Wenbin gave Li Wenxiu a sweet smile and suggested.

After speaking, Zhou Wenbin led Li Wenxiu to leave the crowd first.

Seeing this, Zhou Wenhui and Zhang Xiaomin could only helplessly keep up, and there was a sign of passively eating dog food.
