Thirty years later, Peter Thiel famously said, "People want cars that fly, but Silicon Valley will only cram you with 140 characters."

This refers to the fact that scientific and technological progress is locked at the level of tinkering, and there are fewer and fewer feats of the level of complete annihilation.

The reflection of most people of insight is this: "big data analysis" is too rampant, so investors are becoming more and more "cost-effective", and the delusional people who are willing to "try and make mistakes" are forced to the corners of more and more angel rounds.

IF MASTER LIU CREATED "THE THREE-BODY PROBLEM" 5 YEARS LATER, HE WOULD NOT HAVE TO SPEND A LOT OF TIME DESIGNING THE THREE-BODY PEOPLE TO SEND ZHIZI AND LOCK UP THE BRIDGE OF HUMAN TECHNOLOGY; AS LONG AS HE WRITES THAT THE THREE-BODY PEOPLE CONTROL THE SOCIAL DEMON FACEBOOK AND CULTIVATE ALL MANKIND INTO FOLLOWERS WHO CHASE THE TREND OF ** MUSIC.

This is the paradox of reform and revolution - the better the improvement of "optimizing efficiency/product experience" in the previous era, the later the disruptive revolution of the next era will come. Just as Marx's prediction did not come true in Western Europe, where capital was developed, but in Russia, where capital was stiff.

Data analysis is a good thing to optimize efficiency, and it is naturally a stumbling block to the technological revolution.

As a person of insight who worked in Alipay in later generations, Gu Ao's understanding of the two sides of this is naturally very high-level and comprehensive.

So although he doesn't like smoking, he doesn't hesitate to take the opportunity to warn the world: it doesn't matter if you do something wrong, but you can't lose your free will and leave your choice to authority or machines for fear of making mistakes.

Similarly, I also took the opportunity to condense the dream of Ma Feng in my previous life and then subtly re-indoctrinate it. lest Ma Feng become a superficial person because this life is too smooth.

Gu Biao cannot afford this historical responsibility.

People who have dreams, the more the better, right?

……

Without further ado, in a word, Gu Biao completely calmed down his peers in the planning of advertising shooting, and also clearly conveyed his lofty vision to new friends.

Everyone sighed with emotion and dragged their minds back to watching the game.

After a while, the day's bar competition was over. Li Ning and Ma Yanhong won the men's and women's events respectively, and a sports committee official presented them with awards.

After the gymnastics event, some spectators who bought a single ticket, or were not interested in the follow-up events, left the venue one after another.

And Gu Biao, who got a joint ticket, took a break and prepared to continue for a while.

"What's next? floor exercise? Look at them cleaning up the field. Zhang Yimou, who had nothing to do with himself, asked casually.

Gu Changwei next to him pulled the schedule and glanced at it: "It's martial arts." ”

Then everyone continued to talk about business.

Ma Feng followed the topic just now, and mentioned the performance technique of the last Elite song, and praised Zhang Yimou's shooting:

"Lao Zhang, the last film, although it was an advertisement, was really handsome. How did you shoot it? I used to watch old war movies, and the people in this kind of Mercedes Benz all went from far to near and continued to pull away, and then passed in a flash.

When you were shooting, you chased after Brother Gu for more than ten seconds, so handsome. Can you do the same with Yanghe this time? Can Liqun's 'travel' element also behave like this?"

If it was Ma Feng half a year ago, he would definitely not be able to ask such a professional question, because he definitely didn't know anything about photography. But now that I've been in business with the studio guys for so long, pushing, pulling, and shaking are pretty much clear with these basic common sense concepts.

In the 60s and even before, the camera camera followed people or cars, but few of the camera positions themselves followed the actors.

At most, when the range of movement is not large, it costs a lot of money to take a section of rail car in the studio, but it is only more than 10 meters at most, and it is difficult to get it in the field.

Therefore, when encountering a horse racing scene, the expression can only be to see a person galloping closer, and then disappear away. This is easy to reflect the "fastness" of the horse, but it is not easy to show the heroism of the knight who finally bends the bow and reins in the horse, stands up, and then looks up and drinks, and must switch positions.

And the last time Gu Changwei was in charge, he was sitting in the back seat of the car, holding the camera and following Gu Biao to shoot, and the degree of the effect was by no means comparable to other photographers at the moment.

Ma Feng felt that it was very handsome, and naturally hoped that the list he took back would also be treated so well.

Zhang Yimou and Gu Changwei listened to it, but they complained again and again: "Xiaoma, you don't understand the market, how difficult it is to follow the shooting in the field position, Lao Gu is talented, he has tried many times, and it took hundreds of feet of film to shoot."

I didn't get to the end of this shot, and it took me two cuts to get it back in the later stage. But it's miserable for us, you better don't open this mouth. ”

Ma Feng didn't understand the difficulty, and looked at Gu Biao blankly, trying to get the big guy to "uphold justice".

Gu Biao is also secretly funny: when a layman looks at the excitement, he naturally does not understand the hard work of professionals.

The last time I followed the shooting, without the help of imported equipment, in fact, looking at the whole country, it is estimated that Gu Changwei could shoot it alone - after all, he is the No. 1 photographer in the later generations, he is talented, and his natural feel is particularly stable, which is equivalent to the realm of "man-machine integration".

Even so, the final shooting effect is slightly shaky, but it does not affect the viewing experience, but gives the audience a feeling of "sharpness".

Gu Biao roughly explained the principle here, and Ma Feng was very ashamed and withdrew his needs: "It turns out that it is so difficult to follow in the field...... I didn't learn photography, don't be surprised. ”

Gu Changwei smiled at each other: "It's okay, in fact, it's not impossible for you to follow the wind pulling effect in the field without shaking at all." Don't you have anything to do with Hong Kong businessmen, I heard that there was a device called 'Standicon' in Hollywood three or four years ago.

In the past two years, there has been some development, some large ones are installed in the car to prevent shaking, and some are worn on photographers like vests. I look at the cutting-edge trends in the circle, it seems that Xiangjiang Shaw Brothers spent a huge amount of money to buy a set of cars, and they also boasted in the newspapers of Xiangjiang, and our mentor told us about the news. ”

"Steadycan" is the transliteration of English steady-cam, which is the abbreviation of camera. So the paraphrase is "camera stabilizer", as the name suggests, it is a mechanical anti-shake device.

Decades later, even gadgets like mobile phones will have an "optical image stabilization" design, which is to get some motion compensators next to the camera, and then jointly control them with the G-sensor (gravity acceleration sensor) of the mobile phone itself for closed-loop feedback compensation control, and even rely on graphics software to calculate compensation.

But in the '70s, Standicon didn't have any software compensation, just huge purely mechanical compensation devices, plus simple chips and control circuitry. Because this thing was only tested in a Hollywood laboratory in 1973, and it was just trial-commercialized in Hollywood around 75 years.

At the beginning, it was all large equipment in the car, and it was only in 77 years that Hollywood appeared the first vest-style, that is, it could be worn by photographers.

Historically, this kind of "plaything" did not enter China throughout the 80s, and it was not imported until 92 years after further opening.

If Chinese people want to experience the effect of "Chinese use Standicon to shoot field sports positions for the first time", they can go back and watch the 94 version of "Romance of the Three Kingdoms". In episode 30 "Tongue Battle Group Confucianism", Zhao Zilong rode the savior alone on Changbanpo, and those shots of "looking backwards from Zhao Yun's perspective and watching Cao Jun's generals fall backwards from both sides" are even the highest technology portrayal applied by Standicon at that time.

Ma Feng is not very knowledgeable, he has been messing with Xu Ling of Hujiang Studio for so long, and he has never heard of the term "Standicon", and now he heard Gu Changwei say that the United States has only appeared for two years, and he suddenly feels sorry for his wallet.

"This thing...... It should be expensive, right?" he didn't dare to ask out loud.

"The new stuff that just came out must be expensive. I heard that the most accurate style in Hollywood costs at least 100,000 dollars a piece. Gu Changwei dared to speak, after all, he was just swinging the dragon gate array and pulling the diorama, and he didn't think anyone would plan to buy it.

"Hiss......" Ma Feng gasped and quickly stopped his thoughts.

Hundreds of thousands of dollars, when the new technology was first born, the asking price was really black. This amount of money is enough for Brother Gu to introduce the copyright of two more films in the mainland, but he only used it to buy an auxiliary device for the photographer's anti-shake?

Let's rather continue to shoot with a fixed camera position, and not pursue field shooting with a camera position......

However, just when the parties had stopped thinking, Gu Biao, who had been out of the matter, spoke:

"This kind of thing, in fact, can also be localized, right? The chip and control circuit should not be difficult, the key is the sensitivity of the inertial sensor, or the gravitational acceleration sensor, and the response feedback speed. The higher the accuracy and the faster the feedback calculation, the better the stabilization. ”

As a coder in his later life, Gu Biao didn't have much to do with smartphone software, and the principle in this was naturally to bypass.

"Sensors...... It looks like it's very high-end. Is it because only they can make this kind of sensor because the Americans can sell it so expensive?"

Gu Biao took stock in his heart, and analyzed to himself: "No, the so-called accelerometer, the core is just a gyroscope, if you don't pursue accuracy, there will be more domestic production - well, the best in this area should be the Naval Missile Research Institute."

The inertial navigation error eliminator used in anti-ship missiles has the highest requirements for the accuracy of the gyroscope. I don't know if our current anti-ship missiles can catch up with the civilian ones of the Americans......"

"Why does it have to be an anti-ship missile? Isn't an anti-aircraft missile bad?" Ma Feng asked his intuition when he felt that the target that the air defense missile was tracking faster and the missile was more mobile and flexible.

"You're a layman. Air defense missiles fly at high altitudes throughout the entire process, and there is no problem of using the curvature of the earth to avoid blind spots in local radar blind spots. The enemy's radar can always illuminate the other side, and the inertial navigation error correction of the missile is not so important.

And the ammunition load of the warhead of an anti-ship missile is dozens or even a hundred times greater than that of an anti-aircraft missile. Therefore, it is difficult to penetrate the whole process purely by mobility, and you must use your own brains to conceal yourself. At the same time, fortunately, the target to be attacked by the anti-ship missile is on the water, so the missile can fly close to the sea at an ultra-low altitude and use the curvature of the earth to hide in the blind spot of the opponent's radar.

At this time, there are hundreds of kilometers in between, and the radars of both sides cannot illuminate each other, and they must fly on the target trajectory set at the beginning. At this time, the accuracy and error elimination of inertial navigation are very important.

Therefore, it is necessary to move a certain military technology to civilian use, and give the camera anti-shake feedback. If you only consider the 'sensor accuracy', you should definitely go to someone from the Naval Missile Institute. I don't know if the Navy's current inertial navigation sensors have reached the accuracy of the French 'Exocet' missiles in the early 60s......"

Gu Biao muttered to himself, and the three people next to him were already confused when they heard it, and they were also shocked by Gu Biao's divergent and perverted brain.

It wasn't until there was a roar on the field that Gu Biao was pulled back from his blind brain.

"Oh no! That gold medalist sprained! This move was too dangerous!"

"It's over, it's over, such a serious injury, the athlete's career is definitely coming to an end. It's a pity that I have no future in this life. ”

"But everyone has already won the fifth national gold medal, and it's worth it. ”

Gu Biao came back to his senses: "What's the matter?"

Zhang Yimou pointed and said: "The player in the martial arts routine competition seems to be injured, but he still survived to the end, and it is estimated that he is still a gold medal." That action just now was so exciting. ”

Gu Changwei: "I heard the news just now, it seems to be called Li Lianjie." It's the same age as Brother Gu's pony, it's a pity that his future is gone at such a young age. ”
