When I walked into the Siwo biological laboratory, I saw two spheres with a diameter of 20 cm in the incubator. "The sphere in this incubator is composed of two hemispheres, each of which contains hundreds of billions of neurons, and the time shown on it represents the life time of the sphere. Siwo, connecting biochemical brain No. 1 and No. 2. After Lin Sen finished speaking, he saw two holographic images of circular biochemical brains appearing in the air, and in the two biochemical brains, criss-crossing dense nets of different brightness from light yellow to dark red, just like the dense transportation network of the city at night, showing two lines of numbers, one is the proportion of occupancy, and the other is real-time computing power.

Chen Zhang said solemnly: "When cultivating the biochemical brain, we encountered a problem......

Wen Lin noticed the worried expressions of the three of them and asked, "Is it a moral and ethical issue?" ”

Zhou Zhiqi replied with a serious face: "Yes, although many people can do this kind of thing under the noble banner of studying disability issues, but the biochemical brain has produced consciousness, is it considered a person?" If in the future, thousands of these biochemical brains are imprisoned in this sphere, soaked in these incubators, just to do such a thing, is it another kind of slavery? Another kind of prison? ”

Zhou Zhiqi's voice fell, everyone was silent for a moment, and Lin Sen continued: "In the process of cultivating and researching these two biochemical brains, we have a general understanding of the brain's computing mechanism, and we also roughly understand the nature of consciousness. Let's start with the conclusions: First, the degree of brain development cannot reach 100%, which is limited by the limits of neuronal cells and brain organs. Second, the consciousness of the brain itself cannot be transferred or replicated. ”

Wen Lin thought for a moment after hearing the conclusion: "The first one can be understood from the perspective of living organisms, after all, if the bioelectricity is too strong, it will really burn the brain." ”

"Yes, we are looking at how to increase the computing power of the brain, and there are two ways: first, to increase the degree of brain development; Second, increase the volume of the brain. Whether it is the first method or the second method, it involves the bioelectric limit and energy supply limit of neuronal cells, and the bioelectric limit and energy supply limit of brain organs. At present, Einstein, who is recognized as the smartest person in the world, has a brain development degree of 13%, but it does not mean that Einstein's brain computing power is still 87% undeveloped. ”

Wen Lin nodded: "Indeed, epilepsy is the result of abnormal brain discharge. ”

"Since there is a limit to a single brain, can we make a brain matrix? But if you think about it, isn't this brain matrix a group effect? In real life, multi-person cooperation improves efficiency, but multi-person decision-making is a different story, and in fact, teamwork can sometimes evolve into a crab effect, and our experiments confirm this. As he spoke, Lin Sen pointed to the two biochemical brains in the air: "Siwo, connect the left brain and the right brain of biochemical brain No. 1 and No. 2." "When the two biochemical brains are connected, the computing power displayed in the holographic image becomes unstable," the result is that the consciousness of the two brains is not compatible, and there is a split personality, and the integration of consciousness is not realized, so as to achieve the superposition of computing power 1+1=2, which is the same as the situation of two people in reality. This brings us to the second conclusion, that the consciousness of the brain itself cannot be transferred or replicated. ”

Wen Lin asked with a little surprise, "So it seems that you have touched the door of consciousness?" ”

Lin Sen pondered for a moment and replied, "Human consciousness is the ecology of tens of billions of neuronal cells growing together in the cerebral cortex. ”

Zhou Zhiqi added: "The cortex is like the earth, the neurons are like the trees that grow on the earth, and each forest is like a person's consciousness. ”

Wen Lin understood at this time: "There is no same leaf in the world, and consciousness cannot be replicated; The forest cannot be replicated, consciousness cannot be transferred. After speaking, he sighed, maybe a relief, maybe a loss.

Chen Zhang said: "Siwo, connect Biochemical Brain No. 1 with Computing Cluster No. 1, and connect Biochemical Brain No. 2 with Computing Cluster No. 2. Biochemical Brain 1 is set as the main control, and Biochemical Brain 2 is set as the slave control. "I saw that the peak of the total computing power of Biochemical Brain 1 far exceeded the total computing power of Biochemical Brain 2, but the numerical change was much higher than that of Biochemical Brain 2.

"The fluctuation of this value comes from consciousness."
