Ning Changsheng smiled and said: "Theoretically, it is possible. After all, animals and plants are also made of matter. If we can do atomic level manufacturing, we can realize the manufacturing of animals and plants.".net
Zuo Dajun looked surprised, "This... is really possible! If it is really realized, then using such technology, we can't just make animals and plants casually. As long as there are sufficient resources and energy, then we don't want to Make as much as you can, then...then...what will this world become?"
Animals and plants can be manufactured in the same way as those industrial products, which is a bit scary.
Related technologies can be used in good ways, but if they are used in bad ways, the consequences will be disastrous.
If that were to happen, I don’t know what the world would be like.
Ning Changsheng went on to explain: "I don't know what the world will become, but with the development of science and technology, related technologies will appear sooner or later. Speaking of which, with the arrival of neutrino detection equipment, this aspect will be greatly accelerated. The development of technology."
The emergence of neutrino detection equipment will change many things that were not possible in the past.
You should know that detection technology in the past relied on electrons and photons. Due to the interaction of electrons and photons with matter, the detection effect was not so good.
But neutrino detection equipment that detects neutrinos is different.
Detection at the atomic level is easy, and detection at the nuclear level is not difficult either.
The most important thing is that it has strong penetrability.
If you think about it, you will know that with neutrino detection equipment, the situation will be completely different.
It can be said that all walks of life will be changed by the emergence of neutrino detection equipment, and science and technology will usher in explosive development.
Xu Zhengping smiled and said: "Yes! That's for sure. Neutrino detection technology is a disruptive technology and its impact is far-reaching. When it comes to manufacturing animals and plants, as far as I know, it seems that human organ manufacturing technology has been successful. .”
In the past, there was a great need for organ transplantation.
At that time, the sources of organs were mostly donations. As for other sources, they were basically non-existent.
Even the simplest cornea cannot be manufactured artificially, let alone those complex organs.
Of course, this is the past.
It's different now.
As far as the current situation is concerned, medical technology is no longer comparable to what it used to be.
Under normal circumstances, after treatment, very few people need organ transplants. This is only possible due to the advancement of current medical technology.
In other words, there are many, many fewer people who need organ transplants now than in the past.
Even those who need organs for transplant no longer rely on donations from others as they did in the past.
The most important source of organs now is culture.
For example, if a person's heart needs to be transplanted, the transplanted person's cells will be cultured some time in advance.
Through purposeful cultivation and induction, the heart is developed and grown.
This involves gene expression and cultivation methods.
As for this technology, it was only developed not long ago.
There is essentially no difference between the organs cultured by this method and the transplanted organs, and there will be no immune rejection.
Unlike in the past, no matter how matched the allogeneic transplanted organs are, there is still some immune rejection.
In this way, immune rejection will not occur.
Nowadays, people jokingly say that as long as there is no problem with the brain, any part of the human body can now be replaced.
Just so domineering.
Before that, there were industrially manufactured organs, that is, artificial organs.
This kind of artificial organ only realizes the function of the organ. As for making strange materials, they are various metals, synthetic materials and the like.
Although these artificial organs are very useful, the human body also rejects them.
Anyway, not
It’s good to have the original organs.
It stands to reason that these two methods are completely sufficient.
But there are always people who have sudden whims, are not satisfied with the current situation, and want to create something even more powerful.
That's making organs.
Speaking of which, it is feasible to obtain organs through culture, but it requires a lot of energy.
If we want to talk about the reason, it is that the success rate is not very high during the training process.
There are too many uncertain factors in the training process.
Generally, when cultivating organs, many groups are cultured at one time, and the fear is failure.
This will consume a lot of energy.
But directly making organs is different.
The raw materials used in this manufacturing method are very particular.
Not metals or synthetic materials, but fats, proteins, sugars, etc.
It's simple.
The cells of the transplanted person are used to cultivate many "raw materials".
The raw materials can be fat, protein, sugar, etc., or they can be cells, etc.
These raw materials are then used to create organs.
In this way, there is no essential difference between manufactured organs, cultured organs, and original organs.
After this kind of organ transplantation, there will be no immune rejection, and it is no different from the original organ.
There is no difference between this kind of manufactured organs and cultured organs. If there is a difference, it is that the former is faster and has a higher success rate than the latter.
The former "raw materials" are cultivated very quickly, unlike the latter.
Zuo Dajun nodded and said with a smile: "I also know this news. I heard that it has been successfully tested on a hundred pigs. To be honest, this technology is incredible. This is making organs! This reminds me of If artificial food continues to develop like this, there will be no need for any breeding industry. We can make it directly. That’s right, it has already been there, and it is becoming more and more real. If you don’t distinguish it, it will really be unknown."
This reminded him of an experience he had in the school cafeteria.
That time, when I was eating in the canteen, I heard two groups of people arguing in the canteen.
The reason why they quarreled was because of braised pork.
There were a total of ten plates of braised pork that time, five of which were made with artificial meat.
He said he was looking for these five plates of braised pork stir-fried with artificial meat.
As a result, all ten plates of braised pork were eaten, and these people did not find them. In the end, one party was dissatisfied and started a quarrel in the cafeteria.
Finally, one party came up with artificial meat.
Put this artificial meat in front of the chef and let the chef distinguish it, and the chef can't tell the difference.
Yes!
Today’s artificial meat is so powerful.
Of course, artificial organs require much more rigorous technology than artificial meat.
Fan Xiaoming said with a smile: "Those people originally had such a purpose, let's put it this way! Many of those who study the production of animals and plants study food synthesis, which is the food we usually eat. Those people study and study I became interested in making animals and plants. To be honest, if there is a difference between them synthesizing food and making animals and plants, it is that the former is not alive, while the latter is alive. I also know the technology for making organs. Yes, I heard it seems to be successful, but it has not been tried on humans yet.”
At the end, Fan Xiaoming looked at Ning Changsheng.
Ning Changsheng nodded and said: "Indeed! The technology of organ production has been successful. How can I say that this technology is actually quite mature, but we are still worried. We will continue to observe and study it for a while before using it on people. , Speaking of which, organ manufacturing technology has wider uses than organ culture technology. For example, it is too difficult to achieve a person’s entire hand using organ culture technology, but it is very simple with organ manufacturing technology.”
When Ning Changsheng said this, several people were surprised.
Zuo Dajun sighed: "This...this
How long has it been for this to happen? This is too exaggerated, I can’t believe it! This is too powerful. Now that it's like this, does that mean that the parts on people's bodies can be replaced at will? "
Ning Changsheng shook his head and said: "No, even if it is a simple replacement of the body's organs, it must be inspected. Only those that really need to be replaced can be replaced. It cannot be replaced if it is not necessary."
Fan Xiaoming smiled and said, "If you could change it at will, it wouldn't be a mess. Everyone would change their body to a younger one."
If there were no restrictions on organ replacement, it would be chaos.
Ning Changsheng nodded and said: "According to the current technology, except for the human brain, everything else can be replaced. If there are no restrictions, everyone will think about replacing the entire body except the brain. Of course, also It’s not that the whole thing can’t be replaced, it can only be done when necessary. Simply put, it will only be done when life is endangered. We won’t publicize it to the outside world like this now. If we do it truthfully, we don’t know how it will attract the public. How much trouble."
It was still difficult to do this before, but now with neutrino detection equipment, the results are different.
The difficulty has been reduced a lot.
Zuo Dajun's face was full of surprise, "What? It can be done now. This... this is too exaggerated! This must not be publicized to the outside world and must be kept secret. If everyone knows this, it will be okay. It is unimaginable. ! Well, why can’t the brain be replaced? If the brain can be replaced, will that person achieve immortality in disguise?”
Constantly replacing the organs in the body to keep oneself young, this is also a disguised form of immortality.
Fan Xiaoming smiled and said: "Da Jun! You are really smart. What do you think? If you replace your brain, will the replaced brain still be yours? According to current research, how can you replace other organs in your body, as long as the brain is not replaced? , then you are still you, if you change your brain, it won’t be you.”
There is no doubt that the brain is the carrier of consciousness.
Any organ in the body can be replaced, but the brain cannot be replaced.
Because once the brain is replaced, it is no longer the person.
Ning Changsheng nodded and said, "That's true. You can't replace the brain now. It's not only a technical issue, but also an ethical issue. In the process of researching immortality, many methods have been thought of. The most direct one is to rely on oneself to achieve immortality. Come on, judging from the current situation, the maximum life span of a human being is one hundred and fifty years. This limit will continue to increase with the development of science and technology. As for whether immortality can ultimately be achieved, it is possible if we study genetic genes. Yes, this method of immortality faces technical problems, but there are no ethical problems.”
Zuo Dajun nodded excitedly, "Yes! Yes! It can be said that this is the most desirable way of immortality for human beings."
Several people also smiled and nodded.
Ning Changsheng smiled and continued: "There is only one other way, and that is to change the brain, or to change the carrier of consciousness. This carrier can be the brain or the intellectual brain. In layman's terms, the former is soul transfer, and the latter is As for the former, consciousness uploading means using your genetic genes to cultivate or create a body that is exactly the same as yours. Of course, this body will be younger. Although this body is also a life, its consciousness is blank. Then It means copying your memory, consciousness, etc. into the brain of the new body. When your body gets old, you only need to do it again. As long as this cycle continues, you can achieve immortality and become immortal. .”
Fan Xiaoming nodded and said: "This method is indeed possible, but it has major ethical risks. Will I still be myself when I am old? How to deal with it? Moreover, if new consciousnesses are killed, if many copies are made at once, which one will be considered the right one? You, these are all problems you have to face, and if you don’t have corresponding countermeasures, you don’t know what the world will be like.”
Zuo Dajun's face was full of horror, "This... this is too scary!"
Ning Changsheng smiled and said: "Yes! This is the ethical problem of this method. This is soul transfer, to be precise, it is soul copying, and then the consciousness is uploaded. This has the same ethics as soul copying. To When it comes to soul copying or human beings, then consciousness uploading,
Strictly speaking, they are no longer human beings. As far as the current situation is concerned, whether it is soul copying or consciousness uploading, there are still technical difficulties. Relatively speaking, it is simpler to implement. "
Zuo Dajun sighed: "I still choose the first way of immortality. Soul copying and consciousness uploading are a bit perverted. Think about it, once the soul is copied and consciousness is uploaded, there will be two selves, and the former must be killed. , if you don’t do it, then that one is you. If it is copied many, many times, then that one is you. To be honest, it’s hard to explain. It’s scary to think about it. No! No! Related technical research is OK, but The strictest supervision and restrictions must be implemented. If such a technology is mastered by someone with intentions, the consequences will be really disastrous."
Fan Xiaoming nodded and said: "Supervision and restrictions are inevitable. Not to mention such technologies, even technologies that are very harmful will be supervised and restricted. If there is no supervision or restrictions, and a madman masters these technologies, then this madman will It will keep copying itself, and what the world will become is terrifying to think about!"
Just thinking about it makes me worry about the future of mankind.
At this stage, relevant technologies can be supervised and restricted, but as time goes by, changes may occur.
Such a situation is bound to happen in human history.
It’s scary to think about it now, maybe it will be different in the future.
