Around this, everyone is full of curiosity and apprehension, and two extremely contradictory feelings appear in people's minds.

On the one hand, it is excellent, and on the other hand, it is extremely bad!

This feeling is a bit like primitive people talking about various modern potions, not knowing their principles, and can only guess blindly. People can't tell whether Perfectin is a "stimulant" or a real "tonic", and they don't know if they will kill themselves after large-scale use......

In a quarter of an hour, the scientists here discussed a variety of different results. These results made Yu Yifeng in a dilemma, and he kept swaying......

First, genetic screening, of course, is not a good thing!

This is a conjecture with the greatest malice.

Just like the genetic modification broadcast of an advanced civilization, perfection is just a biological experiment, and if this is screened from generation to generation, maybe human beings will be screened into other civilizations......

"Yes, the human species has changed like this!"

"GM broadcasts, just make you look different. And Perfection Vegetarian can change the whole race! What will change is your next generation, the next generation...... Cleverness, longevity is just a front to lure you to use! ”

"Impossible, no matter how human genetic material is screened, it is still human genes! It can't be any other species! In our example, we did not find any changes at the genetic level or at the chromosomal level...... It's still 46 chromosomes, and there's nothing wrong with that! ”

"And...... There is no reproductive isolation between superhumans and ordinary humans! ”

"No! Insecurity! We don't know much about the genetic level, and you can't guarantee what will happen in a few generations......"

Several experts expressed their opinions, but no one could convince anyone, and the atmosphere in the venue became tense.

All in all, this change seems to be good, but in fact, maybe its bad effects will not be apparent until dozens of generations later.

"Dozens of generations later, human beings have become another civilization, or have they become unintelligent, hairy and blood-drinking beasts?"

Yu Yifeng himself was very uncomfortable with this statement, as if he was referring to him.

But he did not directly reject this view...... Something that doesn't know how it works always seems unsafe.

However, this kind of "conspiracy theory" always has one of the biggest problems: if you want to change one species to another, why bother so much?

Is there any benefit to be made?

It is a bit unsubstantiated to just boil it down to "experiments".

The second statement, genetic screening, is of course a great thing!

This conjecture does not mention the chaotic conspiracy theories, but believes that the perfection element itself is used by a super civilization to transform itself, and I don't know how it has been circulated, and then it has become an expensive transaction between interstellar civilizations.

Just the longevity bonus, your own intelligence, plus the intelligence of your offspring, are enough!

Why is Perfection an important and expensive trade? It is because it itself is something that has been circulated in advanced civilizations, and it also has a certain use value......

"Among the star civilizations, there is no shortage of ancient civilizations that have existed for millions of years. If there were any side effects of Perfectin, they would have known about it for a long time! Maybe sometime, we can talk to a kinder interstellar civilization. Alas, why is the sower civilization reluctant to tell us......"

"Okay, okay, don't blame the sowers......"

The second argument is extremely beneficial to human beings, because there are so many perfections in human beings.

Compared with the first one, it simply goes to two opposite extremes.

Psychologically, people prefer the second version.

Of course, there is a third conjecture, which is why perfection is related to "intellectual barriers", which is why it seems so expensive.

This statement is an extension of the second conjecture.

Judging from the current level of science and technology, it seems to be very, very difficult to improve the intelligence of civilized individuals......

"Humans may be able to make a cell out of thin air, but ...... Unable to improve their intelligence. ”

"Using technology, such as brain chips, can only improve certain capabilities, but trying to improve abstract thinking skills on a large scale is tantamount to a fool's dream...... At least our technology is far from good! ”

"Unless we can fully understand how the brain works."

"This kind of difficulty may not only be for us, but also for other civilizations that are not of high racial value in their own right. If a civilization has reached the ceiling of its own intelligence after a long period of development, and cannot improve its intelligence, then what should they do? ”

"How can they overcome it?"

"Perhaps...... Should we ask ourselves, how should we overcome the intellectual ceiling? One scientist asked such a question.

Of course, there is a ceiling to intelligence, and the average human intelligence is only 100, and there are many things that cannot be understood.

A good education and long-term effective logical training can indeed improve human intelligence. For example, college students who work hard can increase their intelligence to about 120 through long-term thinking training, but this acquired improvement is still limited, and it is impossible to reach 180 or 200.

With an intelligence of 120, you can accept regular courses such as mathematical analysis and advanced algebra, but when you encounter topology, abstract algebra, partial differentiation and other subjects, it becomes quite difficult and requires very long thinking.

With the in-depth development of various technologies, simple things have been almost excavated, and the difficulty of expansion has skyrocketed, and it is increasingly driven by genius.

During Newton's time, the top mathematics, that is, calculus, and the top physics were Newton's three laws of motion. For these courses, ordinary people can barely pass through studying, and their intelligence is enough.

And now? Any cutting-edge mathematics is no longer something that ordinary people can understand. This is true for ordinary people, and it is also true for geniuses, who still have things that they cannot understand, but their limits are higher.

Information is exploding, but the development of science and technology is slowing down......

One day, when even geniuses find it difficult to understand a higher level of science, this civilization touches its intellectual ceiling.

"How to fix it?"

"When you can't even be a genius!"

The confusion was deeply felt.

Screening again and again is not set by a supreme being, but a natural law.

This kind of physiological barrier is more difficult to solve than the large filter caused by "nuclear fusion" for the first time.

Silent, silent.

If humans encounter this situation, how should it be resolved?

Since there is a civilization that passes through this barrier, there must be a solution.

At this moment, Dr. Rimbaud jumped up, his face was hideous, and he spat out a string of terrifying words: "If you want to break through this ceiling, the first way, of course, is genetic screening!" Directly depriving mediocre people of their reproductive rights, only smart people can have children......"

"Through manual screening, let our future generations become smarter from generation to generation!"

"This is the way to pass through the intellectual barrier!"

Hearing his words, everyone immediately took a breath of cool air.

This sensational anti-human method was quickly refuted by a large number of biologists: "Dr. Rimbaud, you are wrong, intelligence is not something that one or two genes can determine...... Maybe the combination of mediocre people can also give birth to smart children.

"Moreover, for a highly developed interstellar civilization...... This approach is immediately destabilizing society...... Although we don't know the social system of other interstellar civilizations, fertility screening greatly violates the genetic philosophy of 'survival and reproduction', and it is difficult to do it. ”

Rimbaud shook his head: "What you said is indeed right, but this method is the best choice under the all-round intellectual barrier...... You can't deny that it's wrong! The offspring of intelligent people are indeed smarter on the average level, this is the law of statistics. ”

"Relying on the self-evolutionary ability of life, through artificial selection, one generation is smarter and smarter...... It may take tens of thousands, hundreds of thousands of years of evolution to break through this bottleneck. ”

"Is there a better way to do that?"

The expert was speechless and silent.

Technology doesn't work, use the power of nature.

If, really use such a scheme of civilization ...... How ruthless and powerful?!

Yu Yifeng felt that his heart was being tightly held by a big hand, this method was understandable, but it was unacceptable......

But in the vast universe and the starry sky, there is a high probability that such a cruel and crazy civilization exists. In order to progress, they abandoned imbecile individuals and adopted the means of procreation of a small number of people......

What should we do if humanity encounters this cruel bottleneck?

Should this be the case?

Dr. Rimbaud's face turned pale, and he continued, "The second method that comes to mind is of course to use a high-level civilization creation like Perfection Element. It is difficult for a civilization like ours, such a social system, to make up its mind to adopt the first method, alas, ......"

"Perhaps, there is a high-level civilization that provides us with a second solution."

"So it's more expensive...... It is not impossible to even provoke a war for it. ”
