Zhang Yuan was still a little sad. After hibernation this time, he was likely to never see his teacher again.

He couldn't help asking: "Teacher... don't you choose to hibernate? Perhaps, you can reach your future home planet through hibernation and wake up again."

Academician Ding waved his hand: "No, according to the doctor's advice, my current physical condition may not be able to wake up again after sleeping. Various techniques to extend lifespan will not be effective for people like me who are already seriously aging..."

"I'm old, sometimes I want to take a break, spend some time with a few old friends, and live a life that normal people should live."

"However, before that, there are a few things I want to talk to you about."

Zhang Yuan was shocked and the matter was coming.

The first thing they want to promote in the entire school is the "social public care system". Without this social public care, all the plans that follow are just in vain.

If nothing changes, and develops steadily like now, thousands of years later, they will still be the mediocre human civilization...

This is something that no one wants to see.

Seeing Zhang Yuan and Zhao Qingfeng's serious look, Academician Ding smiled faintly: "Don't have to be so pessimistic. First of all, you can look at this population report. Over the years, the people who choose to become life partners have increased by 422, and only 38 people are still single. Even Zhang Yuan, you have found a life partner, which is gratifying."

Zhang Yuan couldn't help but wrinkle his nose. What does it mean that even I have found a life partner?

After making a little joke, Academician Ding continued: "That is to say, we have about 150,000 couples!"

"And over the past two thousand years, the number of babies born, that is, the new population, has only more than one thousand people. Even under the policy of poor living conditions and discouraging childbirth..."

"Do you know, what does this extremely low fertility rate mean?"

Zhang Yuan was stunned for a moment. The low quality of life caused people's desire to give birth was greatly reduced. This was inevitable.

The population in the spacecraft is basically a highly educated population, not a farmers in the mountains. If the next generation cannot be given a good living environment and cannot be eugenic and procreated, they would rather not have children. This cultural phenomenon has actually appeared in the Earth era. Children are not toys, and the purpose of being born is not simply for the elderly, but also a responsibility and a burden.

Academician Ding continued: "According to the current statistical data, the environment is poor and the material conditions are poor, so the fertility rate is not high, which is easy to understand."

"After arriving at the destination and obtaining a large amount of resources, the first point we need to overcome in the future is to solve the problem of survival and improve our living environment. The first priority of a person is survival. If you can't even eat enough and your material needs are not met, you can't do anything else, let alone ideals and morals."

Zhang Yuan nodded, it was natural.

"But there are also some developments. Some technologies can significantly improve the quality of life and improve fertility rates. Some technologies can gain spiritual enjoyment, get appointments, and some can improve medical services... I think the most important thing is to reproduce the biotechnology on the earth and significantly increase the average life expectancy! Instead of other fancy things..."

Zhang Yuan opened his mouth: "Why?"

"Labor force, extending life is to increase labor force!"

"For you young people, the life-long prolongation effect of various technologies will be much better, that is... everyone can live two hundred years old or even three hundred years old."

"Anyway, these technologies were invented by the Earthlings, and we don't need to pay patent fees or raise prices. To make profits, we just treat it as a welfare for the whole nation!"

"And, the people will definitely not have any objections. If they live for a long time of three hundred years or higher quality of life, they can only live for 150 years, and choose one of the two, I believe that most people will choose to live for a long time."

Zhang Yuan nodded.

Academician Ding whispered: "More importantly, this can reduce the desire to 'birth and elderly care'..."

"The natural population growth rate will continue to be greatly suppressed!"

"You think about it, the work pressure is very high, the life span is elongating, the society is booming, and no elders force these young people to have children. Naturally, everyone will think about rebirth later and let their children enjoy a brighter tomorrow. According to the historical experience on the earth, there are many people who have children at the age of 100... It seems that it is no big deal to delay for decades."

Zhang Yuan pondered for a moment and said in confusion: "But, don't we need a large population... Now there are only 500,000 people, which is far from industrialized enough."

Academician Ding smiled, and this smile gradually turned into a sharp edge like steel.

He said word by word: "We need population, but we don't need natural-born population!"

"The natural-born population is definitely a huge obstacle to the social public care system! Moreover, the birth speed of natural population is too slow... too slow."

"Time is not on our side. The equipment carried on our spacecraft is limited and the population is limited. Once these equipment is fully activated, it will age and depreciate quickly. At most, they can only last for decades."

"...High-quality population is basically concentrated in our generation. We are the elites selected from the 10 billion people and are high-tech talents in various systems. The generations behind us, in terms of intelligence or other basic abilities, cannot be compared with us..."

"So, what will happen in the future? Even if we are let go of our birth, the birth rate in one year will definitely not exceed 2! It is impossible to double in 30 years. We are not farmers."

“Without enough population, there is no way to achieve industrialization!”

"When all our generation grows old and dies, and when the failure rate of spacecraft increases, if a complete industrial system has not been established, our descendants will be extinct on this alien planet!"

Zhang Yuan took a deep breath and tried hard to think about the possibility of this future occurrence.

Yes, it will happen! It is highly likely that it will happen!

The alien planet is not the earth. The ecological environment is extremely harsh and there is no strong industry. The spacecraft is gradually aging again, and all kinds of mistakes are emerging one after another. After the spacecraft is scrapped, everyone will wait to die!

"...In this situation where there is no choice, we must grow the population rapidly! With very low natural desire for fertility, using artificial uterine technology to cultivate babies in large quantities has become the only option!"

When Earth Age departed from Earth, it had its own human gene library, including sperm and eggs provided by excellent genes.

"So, a large number of artificial babies appeared. They grew up from artificial uteruses and were raised by robots since childhood. They were ideologically different from us natural people... I call them new humans."

"This process will be about twenty to thirty years. By then, millions of new humans raised by robots have significantly exceeded those of natural people. They have entered society and exerted their influence."
