Zhang Yuan still felt a little sad in his heart, after this hibernation, there was a high probability that he would never see his teacher again.

He couldn't help but ask, "Teacher...... Don't you choose to hibernate? Perhaps, it is possible to wake up after reaching the future home planet through hibernation. ”

Academician Ding waved his hand: "No, according to the doctor's advice, my current physical state, maybe I won't be able to wake up again after falling asleep." The various life-prolonging techniques will not work very well for people like me, who are already severely aging......"

"When I'm older, sometimes I want to take a break, retire with a few old friends, and live a little bit of the life that a normal person should live."

"Before I do that, though, there's a few things I'd like to talk to you about."

Zhang Yuan's spirit was shocked, and the business was coming.

The first thing they want to promote as a whole school is the "social public support system", without which all the plans are just talk.

If nothing changes, and they continue to develop as peacefully and steadily as they do now, they will still be the same mediocre human civilization after a thousand years......

This is something that no one wants to see.

Seeing Zhang Yuan and Zhao Qingfeng's serious faces, Academician Ding smiled faintly: "Don't be so pessimistic. First of all, if you look at this population report, the number of people who choose to be life partners has increased by 422% over the years, and only 38% of the population is still single. Even Zhang Yuan, you have found a life partner, congratulations. ”

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: "In other words, we have about 150,000 couples! ”

"And for 2,000 years, the number of babies born, that is, the new population, is only more than 1,000 people, even under the policy of poor living conditions and discourage childbearing......"

"Do you know what this extremely low fertility rate means?"

Zhang Yuan was stunned, the quality of life is not high, which leads to a significant decrease in people's fertility intentions, which is inevitable.

The population in the spaceship is basically a highly educated population, not farmers in the mountains, and if they can't give the next generation a good living environment and can't give birth to good children, they would rather not give birth. This kind of cultural phenomenon, in fact, has appeared in the earth age, children are not toys, the purpose of birth is not simply to provide for the elderly, but also to say that it is a responsibility, a burden.

Academician Ding continued: "According to the current statistics, the environment is not good, 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 lot of resources, the first point we have to overcome in the future is to solve the problem of survival and improve our living environment. The first duty of human beings is survival, and if they can't even eat enough and their material needs are not satisfied, they can't do other things at all, let alone any ideal morality. ”

Zhang Yuan nodded, this is natural.

"But there is also a sequence of developments, some technologies can significantly improve the quality of life, increase fertility rates, some technologies can achieve spiritual enjoyment, get appointments, and some can improve medical services...... I think the most important thing is to recreate biotechnology on Earth and dramatically increase life expectancy! And not all the bells and whistles......"

Zhang Yuan opened his mouth: "Why?" ”

"O labor force, to extend life is to increase labor force!"

"For you young people, the effect of various technologies on life extension will be much better, that is...... Everyone can live to be 200 or even 300 years old. ”

"Anyway, these technologies were invented by earthlings, and we don't need to pay royalties, nor do we need to raise prices, and make profits, so it's a national welfare!"

"And there will be no objections from the people. If you live 300 years long, or a higher quality of life, but only live 150 years old, I believe that most people will choose to live a long life. ”

Zhang Yuan nodded.

Academician Ding said in a low voice: "More importantly, in this way, the will to 'have children and provide for the elderly' can be reduced......"

"The natural growth rate of the population will continue to be significantly suppressed!"

"You think, the work pressure is very high, the life expectancy is lengthening, the society is thriving, and there are no elders forcing this group of young people to have children. Naturally, everyone will want to regenerate later, so that their children can enjoy a brighter tomorrow. According to the historical experience of the earth, it is not uncommon for children to have children at the age of 100...... A few decades of delay doesn't seem like a big deal. ”

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

Academician Ding smiled, and this smile gradually turned into a steely edge.

"We need a population, but we don't need a naturally born population!" ”

"The naturally born population is definitely a huge obstacle to the social public support system! Moreover, the rate of birth of the natural population is too slow...... Too slow, too slow. ”

"Time is not on our side, the equipment carried by our spacecraft is limited, the population is also limited, and once these equipment is fully activated, it will quickly age and depreciate, and they can only last for a few decades at most."

“…… The high-quality population is also basically concentrated in our generation, and we are the elite selected from the 10 billion people, and we are high-tech talents in various systems. The generations that followed, in terms of intelligence or other basic abilities, could not be compared with us......"

So, what will happen in the future? Even if our group of people let go of birth, the birth rate in a year will definitely not exceed 2%! There is no way to double in 30 years, and we are not farmers. ”

"Without enough population, there is no way to industrialize!"

"When all of our generation is old and dead, and when the failure rate of the spaceship is getting higher and higher, 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 to think about the possibility of this future.

Yes, it will happen! There is a high probability that it will happen!

The alien planet is not the earth, the ecological environment is extremely harsh, there is no strong industry, the spaceship has begun to slowly age, all kinds of mistakes are endless, and when the spaceship is scrapped, everyone is waiting to die!

“…… In this situation, we have to grow the population rapidly! When the natural fertility intention is very low, the use of artificial uterine technology to cultivate babies in large quantities has become the only option! ”

When Earth Age set off from Earth, it brought its own human gene pool, including sperm and eggs provided by excellent genetics.

"As a result, a large number of artificial babies appeared, they were fatherless and motherless, they grew up in artificial wombs, raised by robots from a young age, and they are not ideologically different from us natural people...... I call them the New Humans. ”

"This process, about 20 to 30 years. When the time comes, it will be raised by robots. Millions of new humans, vastly outnumbered natural humans, have stepped onto society and exerted their influence. ”

"They are the natural supporters of the social public maintenance system."
