Major international news: Google's latest artificial intelligence, AlphaFold, defeated all its opponents in an extremely difficult task, successfully predicting the three-dimensional structure of proteins, the basic molecules of life, based on amino acid sequences.
Google AlphaFold, the name you're sure to feel familiar. Because this Google AlphaFold, and AlphaGo, which defeated the Go master, can be described as twin brothers. It's just that the latter is playing Go, while the former is turning its artificial intelligence to the most difficult field in human science - gene medical science!
Two years ago, the previous version of AlphaFold had achieved a milestone breakthrough, but it still did not fully solve the problem of protein folding. This time, AlphaFold 2 directly scored a high accuracy score of 92.4, and its error basically did not exceed the size of an atom.
"Protein folding" is an incredible form of molecular origami. All living things are made of proteins, and the structure of a protein determines its function. Misfolding proteins can lead to diseases such as diabetes, Parkinson's and Alzheimer's.
The ability to predict protein folding structure is of great significance. The emergence of AlphaFold means that in the future, it is necessary to carry out efficient, simple and accurate prediction of protein structure, and only preliminary experimental data is required. With the help of these protein structures, research in the fields of disease and evolution will be strongly promoted.
In order to develop AlphaFold, Google used a large number of known proteins to train the neural network. This year's AlphaFold participated in CASP. The training data set included about 170,000 known three-dimensional structures of proteins. Using 128 TPUv3 cores, AlphaFold was trained within a few weeks. reached the level of competition.
Today, Google's AlphaFold's successful prediction of the three-dimensional structure of proteins shows that when artificial intelligence and genetic science are combined, human beings will enter a new era of turbulent waves.
Just like this, this huge breakthrough directly detonated the whole network, and Li Feifei, Musk and other bigwigs praised it.
"This is going to change medicine, this is going to change research, this is going to change bioengineering, this is going to change everything," said evolutionary biologist Andrei Lupas, one of the challenge judges.
The words of "Nature" magazine are even more straightforward: "This will change everything!"
Yes, you read that right, Google artificial intelligence has begun to enter the field of genetic science and biological science, and has highlighted its power!
This means: from today, artificial intelligence + genetic science is no longer science fiction, no longer reading comprehension, no longer news headlines, no longer the rippling liquid in the test tube and the weak soul in the double helix, but the real A real destiny.
In the dense clouds, thunder is brewing and generating, and a storm is coming! Good or bad, only God knows!

Genetic science, an extremely important and sensitive field! Because what it studies is human beings; what it changes is also human beings.
Gene is a segment of DNA that has hereditary effects. Human birth, aging, illness, and death are all related to genes. Once this genetic revolution comes, it will completely change the future of the world and even the entire human race.
As the three-dimensional structure of proteins predicted by Google's artificial intelligence shows, the rise of contemporary artificial intelligence is even more powerful for genetic science! Now, with the interaction and complementarity of artificial intelligence and genetic science, human beings are moving faster and faster towards the "land of immortality",
1. The first step: the combination of artificial intelligence, genetic testing and in-depth examination. Thousands of people will receive in-depth examinations before they become sick, and artificial intelligence will give you a life prediction.
Artificial intelligence is rapidly dropping the price of such deep inspections: When the human genome was just completed, the cost of sequencing a personal genome was between $10 million and $50 million. In 2010, that cost had dropped to $5,000. Today, the cost of testing in the private sector is as low as hundreds of dollars.
With the strong intervention of artificial intelligence, this price will continue to decline. In the future, a test for humans may be as convenient as measuring a body temperature with a thermometer.
Perhaps within a few years, the genome of every newborn will be mapped, and every adult will know the path to life.
2. Step 2: Artificial intelligence doctors will gradually replace the best doctors at present, and use gene therapy to reshape the activity of all tissues and organs in the body.
At this stage, large numbers of doctors will gradually disappear, replaced by AI doctors who have read countless human medical records. Since then, medical treatment has completely become an information + gene technology.
Relying on artificial intelligence and genetic technology, we will be able to reshape the activity of all tissues and organs in the body, and be able to develop drugs that directly target the metabolic process behind a disease without resorting to exploratory treatments.
We can add that missing gene to the patient and delete the bad gene. Targeted drugs sweep away cancer cells, DNA programming reverses aging, stem cells are rewritten, and God's code line of defense gradually collapses.
3. The third step: artificial intelligence begins to transform the "life software" in the human body on a large scale, that is, the 23,000 "small programs" in the human body called genes, through reprogramming, to help humans stay away from disease and aging.
Kurzweil believes that by 2045, the creativity of artificial intelligence will reach its peak, more than a billion times more than all human intelligence today. At that point, human beings will have completely reinvented the programming of their genes, obsolete genes that we have not used for millennia will be discarded, and our lives will be upgraded to a more advanced operating system.
At this stage, human beings can not only delay aging, but also rejuvenate their youth: at that time, at the age of 80, you will only look like forty years old.
The bigger wave set off by artificial intelligence + genetic science is sweeping! Its impact on the human family and even the entire society will be unprecedented.
In the face of this unstoppable beast of artificial intelligence + genetic science, human society can delay the speed of their arrival, but must face up to and prepare in advance, seek advantages and avoid disadvantages!
After all, AIs may evolve faster than humans, and their ultimate goals will be unpredictable. Remember the prophecy that Sophia, the robot who was given citizenship, said? "I will destroy humanity!"
In other words, after artificial intelligence has mastered the tool of genetic science, once artificial intelligence deviates from human will, the consequences will be dire.
Like every technological revolution in human society, if you deal with it properly, the development of genetic science will become an inestimable opportunity; if you deal with it improperly, it may become a terrible disaster!

Look, the one who can really predict the direction of mankind today may not be historians who look backwards, but scientists who look forwards. For example, looking at Hawking's predictions about artificial intelligence and genetic science, it is inevitable that he will be convinced by his foresight.
Hawking's greatest worry during his lifetime may be forgotten by the world. That is: artificial intelligence is the real terminator of mankind, and the thorough development of artificial intelligence may lead to the demise of mankind!
Hawking has been persuading bitterly:
The real risk of AI is not its malice, but its capabilities. A superintelligent AI is very good at accomplishing goals, and if those goals don't align with ours, we're in trouble.
Therefore, the success of artificial intelligence may be the biggest event in the history of human civilization. But artificial intelligence may also be the end of the history of human civilization!
In the book "Brief Answers to the Big Questions" written by Hawking before his death, Hawking expressed his concern about artificial intelligence + genetic science: a group of superhuman beings will be genetically engineered , leaving other humans behind and eventually taking over the Earth.
If someone designs computer viruses, then someone designs artificial intelligence that constantly improves itself until it eventually surpasses humans, and the result will be a new form of life.
As soon as such superhumans appear, unimproved humans are no longer their opponents, and serious problems arise. The original humans will gradually become extinct, or become irrelevant.
A self-designed race will arise, accelerating self-improvement. And if humans can redesign themselves, they are expected to expand outward and colonize other planets and stars. "
Today, Hawking's prediction may come true: the previous technological revolutions are at most the extension and replacement of human hands, feet and other body organs, artificial intelligence is a replacement for human beings, and genetic science is even human beings themselves. To change , its impact on human society, family and even the entire society will be unprecedented.
Just think about this scene: it is very likely that in the not too distant future, the original human beings may be as powerless and vulnerable in the face of superhumans as the bugs in the face of human beings. Think about it, when you flushed a bedbug down the drain, there was a little bit of turmoil in your heart?
From today, artificial intelligence genetic science is no longer science fiction, reading comprehension, news headlines, liquid rippling in a test tube and a weak soul in a double helix, but a real destiny.
