Under the premise of modern high technology, why is there no more clever method than refereeing?

Of course, with the current technology, it is entirely possible to use electronic refereeing.

But FIFA was afraid that the referees would lose their jobs and not be able to control the game.

I do not let you use it.

In fact, since the day of slow-motion replay and computer analysis, FIFA has discussed more than once the possibility of using them to assist referees in awarding penalties, but they have not been able to agree.

With the development of modern football, the pace of the game is getting faster and faster, and the format on the football field is changing rapidly. Sometimes the referee's vision and speed really can't keep up with the pace of the game, and intentional or unintentional misjudgments unfortunately happen. For example, in the last World Cup, Spain's golden goal against South Korea was ruled invalid, which made Spain hate the field again.

The referee's misjudgment mainly occurred on some issues involving boundaries. For example, the offside decision and whether the ball went out of bounds, whether it crossed the goal line, etc. There were also some revenge moves by players on the pitch that escaped the eyes of the law, or faked falls to deceive penalties (Italy eliminated Australia this time).

The use of high-tech analysis on such issues is indeed helpful.

However, the game is not held for practice penalty awards. The use of high-tech replays can seriously affect the consistency of the game and the authority of the referee. Imagine that every penalty is controversial, every time it is replayed, and what is the system of 90 minutes of stoppage time in 90 minutes.

The referee is for the game of football, and he should not be the subject of the game for the sake of accurate decision-making.

The direction of the game and the ability to control the game are important indicators to measure the excellence of the referee, and it is also the greatest significance of the existence of the referee. The referee has a flexible grasp of the scale, while the computer will only mechanically decide yes or no.

Krina and a number of other world-class referees, their experience and level of enforcement are obvious to all, and no matter how big the players are, they will not dispute their decisions. This is not because their decisions are absolutely accurate, but because of their prestige and ability to control the race. The game they enforce never gets out of hand.

And Ivanov's kind of referee who played 20 cards a game did not misjudge, but he made the players lose their minds, and he ruined what should have been a classic duel. Therefore, accuracy is not the highest level of refereeing, and its significance to the game is not as serious as we think.

Therefore, after the basic accuracy, the microscopic adjustment and grasp is the most important, which can only be done by people. This is a chasm that computers cannot bridge – artificial intelligence.

I believe that through my explanation, you can understand why the referee exists.

3 All 1, 3D stereoscopic printer.

The three-dimensional printer uses layers of stacking to make a three-dimensional model, and its operation process is similar to that of a traditional printer, except that the traditional printer prints ink onto paper to form a two-dimensional plane drawing, while the three-dimensional printer is to stack liquid photosensitive resin materials, molten plastic wires, gypsum powder and other materials by spraying binders or extrusion to form a three-dimensional entity.

2. Cloning technology.

Cloning uses biotechnology to produce offspring from asexual reproduction that have exactly the same genetic tissue as the original individual. Scientists call the process of artificial genetic manipulation of animal reproduction cloning, and this biotechnology is called cloning technology, which means asexual reproduction. Cloning technology is known as "biomagnification technology" in modern biology.

3. Artificial intelligence.

Artificial intelligence attempts to understand the essence of intelligence and produce a new kind of intelligent machine that can react in a similar way to human intelligence, and research in this field includes robotics, language recognition, image recognition, natural language processing, and expert systems.

4. Laser technology.

Laser is widely used because of its good directionality, high brightness, and good monochromaticity. Laser processing is one of the most promising areas of laser application, and more than 20 laser processing technologies have been developed.

5. Radiation technology.

In the field of polymer materials, radiation technology has been used in the radiation cross-linking of polyolefins, the radiation curing of unsaturated polyester resins, the radiation vulcanization of rubber, the radiation degradation of polymers and the radiation grafting modification, etc., and many products have been industrially produced.

When we say the pros and cons of biotechnology, we mainly refer to cloning, which has pros and cons.

Pros: 1) Cloning technology can relieve the suffering of women who cannot become mothers.

2) The implementation of cloning experiments has promoted the development of genetics and opened up the prospect of "making" animal organs that can be transplanted into humans.

3) Cloning technology can also be used to detect genetic defects in the fetus. Fertilized egg cloning is used to detect various genetic diseases, and the cloned embryo has exactly the same genetic characteristics as the fetus developing in the womb.

4) Cloning technology can be used for damage to the nervous system. Nerve tissue in adults does not have the ability to regenerate, but stem cells can repair nervous system damage.

In in vitro fertilization (IVF), doctors often need to implant multiple fertilized eggs into the uterus to select one of them for pregnancy. But many women can only provide one egg for fertilization. This problem can be solved very well by cloning.

This egg cell can be cloned into multiple cells for fertilization, thus greatly increasing the pregnancy success rate.

Disadvantages: 1) Cloning will reduce genetic variation, and the individuals produced by cloning have the same genes and the same disease susceptibility, and one disease can destroy the entire population created by cloning. It is conceivable that if a country's herd were all cloned from the same thing, a minor virus could destroy the country's livestock industry.

2) The use of cloning technology will predispose people to the mass reproduction of the most useful individuals in existing populations, rather than promoting the survival of the fittest in the entire population according to the laws of nature. In this sense, cloning technology interferes with natural evolutionary processes.

3) Cloning technology is an expensive technology that requires a lot of money and the involvement of biological professionals, and the failure rate is very high. Dolly was the only result of 277 experiments. Although more advanced technologies have been developed, the success rate is only 2-3%.

4) Genetically modified animals increase the risk of disease contagion. For example, if a cow that produces medicinal milk is infected with the virus, the virus may infect the patient through the milk.

5) The application of cloning technology to the human body will lead to artificial control of the genetic traits of the offspring. At the heart of the debate about cloning technology is the possibility of genetic manipulation of early human embryos. This is unacceptable to many ethicists.

6) Cloning can also be used to create "superhumans", or people with a sturdy physique but low intelligence. Moreover, if cloning can be used effectively in humans, males will lose their genetic significance.

7) The impact of cloning on family relationships will also be enormous. A child born from a DNA clone of his father's DNA can be seen as his father's twin brother, but with a delay of several decades. It's hard to imagine how a person would feel when he or she found out that he or she was nothing more than an exact copy of another person.

Indeed, my life is one. Live at home! Everything will fly.
