AI will steal human work but will create more jobs in these industries.

Elon Musk and Bill Gates have repeatedly warned the public that artificial intelligence will lead to "the end of the world." Therefore, many people have always been afraid of AI, but they are not worried that Skynet in Terminator will become a reality, but that AI will take away the income of the bottom workers, and the rich with these robots and AI equipment. People will become richer and richer.

So in the end, will it really become like this? Well-known analysis firm PricewaterhouseCoopers has released a new report on the artificial intelligence industry, saying that the future of AI is brighter than we think, although robots with AI features can really replace some of the work, but at the same time, they create There are actually more job opportunities.

Specifically, the transportation industry and manufacturing industry are key industries for AI to replace humans. About 38% of transportation jobs and 30% of manufacturing jobs will be replaced by AI in the future. But there are actually many industries that benefit from AI. For example, in the healthcare industry, about 12% of jobs will be replaced by AI, but when AI is popularized in the medical industry, it will also create 34% of jobs.

The final result is that the popularity of AI will achieve a balance in all major industries, and even overall, there will be a certain increase in human jobs.

PricewaterhouseCoopers said: "Our predictions show that artificial intelligence will not lead to technology unemployment, because we expect to replace about 20% of existing jobs in the UK by 2037, and the number created will be similar, if it is specific to the number, 700 Ten thousand jobs will be replaced, 7.2 million jobs will be created, and net employment growth will reach 200,000."

This view was previously approved by the OECD, which said in an earlier report that only 14% of its members' organizations were facing the impact of AI.

You definitely want to know which industries are less affected or even benefited by AI, including:

· Education

· Science & Technology

· Information and Communication

· Accommodation and food service

The industries that are affected are repetitive jobs:

· financial insurance

· retail

· Construction

· Public administration

· Transportation

· Manufacturing

Therefore, although AI will not cause massive unemployment for human beings in the future, we now need to accumulate some of the skills that we have for 20 years of life. Otherwise, even if AI creates more positions in the future, we may not be able to do the job. Time is eliminated, right?

Even if you are preparing for the World Cup, don’t just put these foods in the refrigerator.

The World Cup is going on. Maybe you want to watch the game. Many times you put unfinished food or prepare some food in the refrigerator, but some foods directly in the refrigerator can cause problems such as nutrient loss, poor taste and bacterial growth. It is not suitable for direct storage in the refrigerator.

The refrigerator is not a safe, these foods cannot be stored directly

Leftovers

It is of course possible to leave the leftovers in the refrigerator and refrigerate them in the refrigerator, but you must not put them in the “naked” refrigerator, so that the placement is easy to change. You must cover the plastic wrap or put it in the crisper to put it in the refrigerator. The time for the leftovers left in the refrigerator should not be too long. Try to eat it in two days, and be sure to heat it until it is cooked thoroughly.

Taro, bread and other starchy foods

Taro, Hanamaki. Starch foods such as bread will speed up the drying and hardening. If such foods need to be stored for more than three days, they should be sealed in plastic bags and placed in the freezer for freezing. In addition, bread and biscuits should not be stored together. The moisture in the bread will be transferred to the biscuits, making the biscuits softer and the bread becoming harder, which is not good for both.

Hot food

The temperature of the refrigerator is generally around 4 °C. Only by maintaining such temperature, the food stored in the refrigerator can be put longer. If the hot thing is put directly into the refrigerator, the temperature in the refrigerator will rise, and the refrigerator will store it. The food is prone to deterioration, on the other hand, the workload of the refrigerator compressor is increased, and the refrigerator consumes more electricity and reduces the life of the refrigerator.

Fish

The refrigerating temperature of household refrigerators is about minus 18 °C, and the fish is prone to dehydration or even deterioration when the storage temperature is not lower than 30 °C. For example, squid will appear fish decay in the refrigerator for a long time, so the fish It is best to buy it now and not to put it in the refrigerator for too long.

chocolate

After the chocolate placed in the refrigerator is taken out, the surface is prone to hoarfrost, which not only loses the original mellow taste, but also facilitates the reproduction of bacteria. The optimum temperature for storing chocolate is 5 ° C - 18 ° C. When the room temperature is too high in summer, it can be sealed with a plastic bag and stored in a refrigerator freezer. When removing, do not open it immediately, let it slowly warm to room temperature before eating.

tropical fruit

Banana, lychee, dragon fruit, mango, longan, papaya, rambutan and other tropical fruits are basically cold. The temperature of the refrigerator in a household refrigerator is generally low. If it is placed in the refrigerator, it will "frozen" the fruit. The nutrients of the fruit will be greatly reduced, and it is easy to deteriorate or even rot. Unripe fruit can't be put into the refrigerator, otherwise it will be difficult to mature normally. If you must put the tropical fruit in the refrigerator, you should also put it in a higher temperature vegetable and fruit trough, and the storage time should not exceed two days.

Vegetables

"Cucumber and Green Pepper" will become dark and soft when stored in the refrigerator for too long. Change the taste, the cucumber will also have long hair sticking.

"Tomato": It is easy to become soft and rotten in the refrigerator. The flesh is blistered, loses its umami taste or cracks, and even rots.

"Onion": It will be moldy if it is placed in the refrigerator for too long. If it is cut open to refrigerate, even if the surface of the plastic wrap is wrapped, it will become more and more dry. Lose the spicy taste and speed up its decay.

"Garlic": Once the garlic enters the refrigerator, it will become moldy, and it will not change from the outside. Only the incision can see the mildew.

"Potato": The low temperature will decompose the starch in the potatoes and will become sweet or grit after being placed in the refrigerator, which will affect the taste.

Suggestions for using the refrigerator

● Regularly clean and disinfect the refrigerator, at least once a month, so that the virus does not have a place to live.

● Reasonable storage of food, food and raw separately placed, make full use of fresh-keeping boxes, fresh-keeping bags, plastic wrap and other products.

● Less switch the refrigerator door. After opening the refrigerator door, close and close as soon as possible.

● Store food should not be too full, too tight, and leave a gap to facilitate air convection and save electricity.

to sum up

The refrigerator is a product closely related to our lives. It is also a place that is easy to produce bacteria. It is a great threat to our health. Therefore, we must always keep the interior clean and reasonably store food. Even if we drop a drop of food soup, we must clean it up in time. Because in the frozen environment, he will harden quickly, not only will it be difficult to clean up in the future, but also breed bacteria. It is very necessary to develop a good habit.

Bitcoin prices fell below $6,000 at the end of last month, and the gap was nearly "10 down limit boards"

As the mainstream digital currency, the rise and fall of Bitcoin affects the price trend of the entire encrypted digital currency market. Especially since June this year, the prices of several mainstream encrypted digital currency varieties have dropped significantly.

When the eyes of the world are attracted by the World Cup, a heavy news in the "coin circle" is hitting the psychological defense of many people. On June 28, according to the platform coindesk data, the price of bitcoin fell below $6,000, and the lowest fell to $5848.26. At this time, the highest price reached in January of this year was $17,100, which has fallen by 65.87%, equivalent to 10 down-limits.

What caused Bitcoin prices to shrink gradually after the rapid summit? Blockchain economist Wang Xuezong told the Securities Daily that there are three reasons: first, the diversion of funds by the altcoin; second, the manipulation of various digital currency markets and the insider trading scandal began to appear, and new funds entered the market and began to wait and see. Third, the regulatory signal is more stringent.

Half a year currency price diving

Falling more than 60%

Bitcoin fell below $6,000! The news at the end of June was no less than a deep-water bomb, hitting the psychological defense of many investors. According to the digital currency monitoring platform coindesk data, on June 28 this year, bitcoin prices fell to a minimum of 5,484.26 US dollars. At this time, it has only reached more than five months from its peak of $17,100. Due to the sharp drop in prices, investors tossing coins and miners to close the mining machine became the norm in the Bitcoin circle.

The reason why Bitcoin fell in most of the first half of this year, blockchain economist Wang Xuezong believes that there are three main reasons: First, the altcoin diverted funds. Various altcoins have been introduced into the market under the encouragement of the bitcoin wealth effect, diverting bitcoin investment funds. It has been found that the speculative earnings multiple of some altcoins are far greater than bitcoin, and they change hands to buy altcoin. Second, the manipulation of various digital currency markets and the insider trading scandal began to appear. New funds entered the market and began to wait and see. There was no continuous inflow of funds to maintain the overall market value of the market. Third, the regulatory signals of governments are more stringent, and the speed of entry into the market for new digital currency buyers has fallen.

Wang Xuezong explained to the Securities Daily reporter that retail investors and marginal investors were the first to discover the market opportunities of Bitcoin. It is their investment that created this market. However, most participants use it as speculation rather than investment. . “The market lacks long-term strategies such as institutional investors to stabilize, and speculative early-stage profiters will definitely sell off profits, causing a plunge.”

Tan Zhiyong, chief scientist of Eurostar Technology, told the Securities Daily reporter that "I personally think that on the one hand, it is due to normal fluctuations in the secondary market, and on the other hand, due to policy uncertainty."

Digital currency

Security risks are questioned

According to the "Securities Daily" reporters, in addition to the "falling down" of bitcoin prices, this year, "regulatory policies" and "digital currency stolen" have become important topics for the "coin circle".

In September last year, the central bank and other seven ministries called ICO (token issuing financing) to ban digital currency intraday trading. Bitcoin fell more than 4% in the afternoon, and other currencies fell more than 40%.

In addition, the theft of encrypted digital currency is also one of the factors affecting the price of bitcoin. On June 20th, Bithumb, Korea's largest digital currency trading platform, announced that it had been hacked, and about 35 billion won (about $32 million) of assets were stolen, and all accounts were suspended. As a result, Bitcoin responded. Falling.

The Cheetah Mobile Blockchain Central Laboratory believes that a large number of exchanges are hacked every year, resulting in a large loss of digital assets. Because the encrypted digital currency is not traceable, non-returnable, and anonymous, once the digital asset is lost, it is almost impossible to retrieve it. It is very unsafe to host the private key on the exchange.

In addition, digital currency also has the security risks of account names and passwords. Most users habitually use the same account name and password to register on different websites. If any one of the websites is successfully hacked, all the user names and passwords of the website may be used for the exchange account system. Login attack. After the hacker gains control over the user's escrow account, the hacker can transfer the digital asset.

In addition, digital currency exchanges have also been plagued by manipulation of currency prices. Pang Huadong, an intrinsic capital partner, believes that the biggest problem in the currency market is that all exchanges are isolated islands of information. The same token, the price of the different exchanges is also split. In theory, the exchange can completely control the price, which has the control of the background; there is no price discovery mechanism in the market that is open and transparent, and is not controlled by the exchange, and it is impossible to form a huge derivatives market.

Bitcoin prices in the past two years

Still more than 10 times higher

As the mainstream digital currency, the rise and fall of Bitcoin affects the price trend of the entire encrypted digital currency market. Especially since June this year, the prices of several mainstream encrypted digital currency varieties have dropped significantly.

However, as of yesterday, the "Securities Daily" reporter found. More than half a month after the "bottom", Bitcoin has regained more than $6,600.

"Although Bitcoin is currently down, we have to see that the price of bitcoin was $2,345 a year ago, and the price of bitcoin two years ago was $656," Tan Zhiyong told the Securities Daily reporter, in other words, In the past two years, the price of Bitcoin has risen more than 10 times. "So overall, the market and the entire society's recognition of crypto assets and blockchain technology is gradually improving."

Why do technology products always like blue?

Since Apple added night mode to the iPhone, every night at 10 o'clock, night view mode will make my phone screen turn yellow. When I see a light yellow phone, I will subconsciously tell myself: to start preparing Sleeping, you will enter the state of staying up late if you don't sleep.

Many studies have shown that using mobile phones, iPads and other electronic devices before going to bed can affect sleep quality, induce sleep disorders such as insomnia, and the culprit is blue light.

Blue light refers to high-energy visible light, blue-violet visible light with a wavelength of 400-500 nm. The human body clock is particularly sensitive to blue light in this band. Studies have shown that people exposed to blue light for more than two hours before going to bed, the nervous system that controls the circadian rhythm in the brain will be disturbed, thus affecting the secretion of melatonin.

The decrease in melatonin secretion caused by blue light, in addition to the effects on the retina and sleep, is also indicated by research, which may induce three types of cancer such as breast cancer.

The research paper that first pointed out the hazard of blue light was released in 2001. But since then, until now, the display of electronic devices with blue tones has not decreased. On the contrary, the continuous technology products still use blue as the main color of the products.

From the preset UI main color in the new mobile phone, to the display screen of the service robot, to the dashboard and the central control panel in the car, these products that emit faint blue light have surrounded us. LEDs (light-emitting diodes), energy-saving lamps, and xenon lamps, which are becoming more and more popular, have more blue light than traditional light bulbs.

Blu-ray is not the best choice in an information-intensive environment

Nowadays people process a lot of information from electronic devices every day, which may be a bit like the intelligence officer on the complex console in the twentieth century battlefield. But in the same electronic device usage scenario that handles intensive information, intelligence officials and users of ordinary technology products have very different details.

We hold mobile phones and iPads, which are generally surrounded by blue light and white light. In military cockpits, submarines and other military-grade consoles, the interface of these terminals is mainly dark red or dark orange.

This is because the human eye sees visible light with a wavelength of 605 nm, that is, orange-red, the eyes are most comfortable. This is related to the retinal rod cells (Rod) and retina cone cells (Cone) responsible for photosensitivity in the human retina.

▲ Retinal rod cells (Rod) and retina cone cells (Cone)

Retinal rod cells are more sensitive to moving objects and least sensitive to color, especially orange-red. Retinal cone cells are sensitive to a variety of colors, among which are most sensitive to the identification of orange-red.

Therefore, in an environment where it is necessary to concentrate on the surrounding environment and need to process electronic device information, such as a night driving environment, the use of orange-red dashboard is the most comfortable and safe.

Friends who drive at night may have had such an experience. When looking forward to the road and looking down and down between the mobile phone and the central control screen, there will always be a moment when the eyes are black and nothing can be seen.

This is because when driving at night, observing the road ahead, the eyes will produce longer and more intense visual afterimages. However, when switching to a dashboard, a central control panel, etc., a brighter block of high-energy light is seen, which also leaves a visual residual image in the dark.

There are relatively extreme brightness contrasts and different visual afterimages before and after switching, which causes visual discomfort, which is "glare". The visual fatigue caused by glare is the cause of many nighttime car accidents.

BMW's ancestral orange-red dashboard light has been in use since the 1970s until this year. The reason for using this color is mainly because BMW used to make cars for the military in the early years.

Science fiction movies bring blue light to the stage

Since blue-violet light is so easy to cause visual fatigue, why are so many technology products still in use? Because in the post-Cold War movie of the United States, the high-tech of the future world appears on the screen in blue tones.

▲ Image from: "Blade Runner"

Orange represents the electronic display of the war era, and blue is the complementary color of orange. The widespread use of blue also means the transformation of the old era to the new era after the end of the Cold War.

▲ Image from: 2001: Space Roaming

In the late 1960s, the film "2001: Space Roaming" and "Star Trek" described the future world that people imagined at the time. The main color of the spaceship bridge in the movie was still orange or Orange.

▲ Image from: "Blade Runner"

However, in 1982, "The Blade Runner" was released after the Cold War. As the originator of the science fiction film, its use of yellow and blue tones quickly influenced artists, designers and advertisers at that time.

▲ Image from: "Blade Runner"

In the "Blade Runner", director Ridley Scott painted to the public a future world that they believe to be credible. The technological element of the future world, the main color is blue. In the dark, the blue light that appeared in the display became the "future technology" that people recognized at the time.

At the same time, blue is the color of the sky and the ocean, but among the plants and animals in nature, blue is a relatively scarce color, so it also carries a sense of mystery.

▲ Blue screen in science fiction movies
Later, the science and technology products in science fiction movies, the imagination of the imitators of the predecessors braved the blue light, and also affected the people who later produced and designed cutting-edge technology products. For example, the early blue computer screen, the blue of the hyperlink in the network, the blue of Windows, the blue of Intel, and then the technology giants such as Facebook and Twitter have a preference for blue.

▲ This blue screen is also a terrible problem

Regrettably, these blue light emitted from electronic devices are causing trouble for people who are increasingly obsessed with technology products.

What can we do with Blu-ray?

Although artificial blue light surrounds humans, the sun is still the largest source of blue light for us. According to Zeiss China's data, the amount of blue light that the eye receives for an hour outside the normal cloudy day is 30 times that of a computer sitting in front of the screen for an hour.

However, as human nighttime increases, electronic devices and LEDs increase in light sources, the time and dose of blue light received by the human eye has greatly increased.

Popular culture used to make Blu-ray a symbolic product of electronic product design, so popular culture can also bring the function of orange-red light back to the public. But the re-education of the pop culture of "letting orange-red light replace blue-violet light" has not yet arrived.

Devices such as iOS and Android have begun to popularize night mode, and it does not make people aware of the harm of blue light to the human body, nor can it prevent people from putting down their mobile phones to go to bed early.

In order to minimize the impact of blue on daily life, perhaps we can try these few tricks first:

Use night mode on mobile phones and computer equipment, and use less sleep at night.

Wear glasses that protect the eyes while driving outdoors and while driving

I have to stare at the screen before going to bed.

Don't mess with anti-Blu-ray mobile phone film, inferior film may make your eyes more tired.

The world's most popular private jet: 250 million cheaper than Jack Ma's Gulf Stream but still luxurious

Jack Ma’s private jet is the Gulfstream G550, which is priced at approximately $49.7 million and is the most commonly chosen model for commercial tycoons. However, it is not the most popular, the reason is simple: expensive. Embraer's Phenom 300 series is the world's best-selling private jet, not only for the rich, but also for some commercial aircraft leasing companies.

Recently, Embraer began to officially deliver the Phenom 300E enhanced version, priced at about 10 million US dollars, compared to Jack Ma's Gulfstream G550 cheaper about 250 million yuan. Although classified as a light jet, the Phenom 300E feels a lot of air, with a wing length of 15.5 meters.

The PW535-E turbo engine from Canadian company Pratt & Whitney is capable of generating 1,524 kg of thrust.

Although the fuselage is not too big, but the luggage compartment capacity has reached 2,378 liters, placing nearly a full range of full-size luggage is not a problem.

Entering the cabin, the first thing you see is the horizontal sofa seat. The Phenom 300E can take a total of 10 passengers, but this time the maximum number of models is 8.

The armrests in the middle of the horizontal sofa not only can hold drinks, but also can hold the tablet, which is very convenient. In addition, the whole machine covers WiFi, and high-speed Internet access is not a dream.

The more comfortable seat position basically meets the standards of civil aviation business class. Of course, if you calculate the space ratio of the aircraft, the per capita area is even larger.

There is a 14.1-inch entertainment system on the top of the head, and when the hand is close to the upper touch area, the button backlight will automatically light up, very advanced.

The back part of the pilot is a small food storage room with cabinets, refrigerator, microwave oven, etc.

The bathroom is located at the end of the cabin, the black toilet is cool, with mirrors, sinks, LCD screens, etc.

Handsome pilots, although the test flight is equipped with two, in fact, Phenom 300E supports single flight, and has obtained single flight operation certification.

The Phenom 300E has a speed of 838 km/h and a range of 3,540 km, which is obviously less than the 11,700 km of the Gulfstream G550. However, it is enough to deal with short-haul flights from Beijing to Shanghai (about 1262 km one way).

After sitting in such a private jet for a luxurious lunch, it is undoubtedly very pleasant to reach the destination.
