1. computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second
in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow

computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value
therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world

4. On the one hand, because of the complexity of the human brain, many areas have not been fully developed. On the other hand, learning mathematics has no evolutionary advantage
human brain is very powerful, but in the face of complex and changeable natural environment, we must pre install many moles to deal with it. As for the more complicated mathematical problems, how fast they can be calculated has little effect on people's survival ability. Moreover, after the human brain has pre installed these moles and used up these computing resources, the remaining computing power is still a lot, but it is far from being discretionary
so people can try their best to accomplish some tasks very well, but all of them are the results of arous training. Because hundreds of millions of years of biological evolution is not aimed at completing mathematical operations. The goal of these 100 billion neurons is to survive on the earth. And it's obviously not helpful to finish the math faster
in recent years, computer technology has developed by leaps and bounds. At that time, the computing speed of "dark blue" was about 200 million times per second. At present, tianhe-2, the world's strongest computer made in China, has achieved a computing speed of 3.386 billion times per second, which provides the possibility for computers to defeat the human brain. The wide application of cloud computing and big data makes the development of artificial intelligence even more powerful, and makes dreams come true

in order to verify again who is more powerful between computer and human brain, the online fish competition hall in Beijing Gongti West Road has become a competition place for Super Brain in black and white world, and the first Merrill Valley cup world computer Go Championship was held here
the teams from 9 countries and regions such as China, South Korea, Japan, the United States and France competed fiercely. Finally, the "stone whirlwind" developed by South Korean expert Lin Zaifan defeated "zenith go" from Japan in the final and won the computer championship
but when it comes to the "man-machine war", the computer will not be "smart" on the 19 track black-and-white board of go. In the game between computer and human brain held on the 15th, the computer "stone whirlwind" challenged the Chinese go celebrity champion for seven consecutive laughs. After the start of the competition, "stone whirlwind" layout is particularly thick, once in the dominant position, but unexpectedly in the middle of the line, there was a blind move
in the end, the players win in the match of let 4 and let 5, lose to the computer at the time of let 6, and win with the total score of 2:1. It seems that computer Go program is the way to win over human beings

5. This is my question about the feasibility of artificial intelligence to generate consciousness from the perspective of programming. I personally think that artificial intelligence can never be the same as human beings, but it may damage human interests because of wrong judgment, or be used by bad people, but in fact it is very unlikely to be used by bad people to destroy the world. For details, please refer to nuclear bomb protection measures and computing power, Personal computing power can never compare with that of the state, and high killing robots will definitely be regulated
6. If artificial intelligence is really used in relevant institutions, then it means that some people's jobs will be replaced. For example, many institutions now start to use procts such as Tianmi AI intelligent telephone robot, which means that they only need to make phone calls or window telephone consultation, calling and other functions.

8. Laoyu and Tianyu, the main methods of ancient jade mining, are divided into Ziyu and shanliao. Hetailao jade is called "Ziyu", which has high quality but low yield; The mine is called shanliao, with high output but uneven quality. Hetian jade, especially Ziyu, is mainly proced in the Yulong Kashi River and the karakashi River, known as "Baiyu River" and "Moyu River" in history. Every spring and summer, mountain torrents break out in Kunlun Mountain, surging down the jade ore from the mountain. After tens of thousands of years of repeated grinding, rolling and impact, the impurities are gone, leaving the round and smooth jade like coagulated fat. According to the local jade collectors, every spring and summer, mountain torrents break out in Kunlun Mountain, washing the jade ore down from the mountain. After tens of thousands of years of repeated grinding, rolling and impact, they form jade. They have been collecting jade in Baiyu river for generations. When the flood first subsided, thousands of people fished for jade in Yulongkashi river. Fishing for jade is the main method of jade mining in ancient times. Fishing for jade means picking and fishing for jade in the shoals and shallow rivers. Jade mining is seasonal, mainly in autumn and spring. There are many rivers in the mangmangmang Kunlun Mountains, and the river water is mainly supplied by the melting ice and snow on the mountains. In summer, the temperature rises, the ice and snow melts, the river rises sharply, and the water is surging. At this time, the jade fragments of the original jade ore on the mountain after weathering and denudation are carried down by the flood. When they reach the low mountain and the piedmont area, the jade accumulates in the river beach and riverbed e to the rapid decrease of flow velocity. In autumn, the temperature drops, the river graally falls, and the jade is easy to find. At this time, the temperature is suitable, and people can enter the water. Therefore, autumn has become the main season for people to pick and fish jade. In ancient times, there were official jade mining and civilian jade mining. The first is the official mining, that is, under the supervision of the officials, the jade miners fished the jade, and all the jade obtained belonged to the official. As for folk jade fishing, it was strictly forbidden in the early Qing Dynasty. In order to prevent the people from fishing for jade on their own, the Qing Dynasty was & quot; There are 12 karuns on the dongxihe river outside the western city of Khotan, which are specially designed to inspect the jade mining Hui people;. It was not until the fourth year of Jiaqing (1799) that the jade ban was opened. It was stipulated that jade mining should be carried out after or outside the scope of official jade mining. People were scattered in the daytime or at night to pick or fish jade. As a matter of fact, the ancients could find beautiful jade in the river full of rocks, which mainly depended on people's experience. Local people have accumulated rich experience, they know that jade is the beauty of stone. There are beautiful colors, such as white snow, yellow pear, black ink; It has a lovely luster, moistening like sheep fat; It has fine texture and tenacity. Jade excavation refers to the excavation of Hetian jade gravel in the gravel layer on the river valley terrace, dry beach, ancient river channel and piedmont alluvial fan away from the river bed. The jade in these places is also brought by the running water, but it has already left the river. There is more or less sand cover on the gravel layer, and some of the gravel has been cemented or semi cemented by gypsum and sand. Because the work of digging jade is very arous, it is limited to a very small area for a long time, and the rate of acquisition is very low, so the effect is not as obvious as picking jade. Therefore, there are not many people engaged in digging jade. Only when there is reliable news of jade coming out in a certain place, and there is great hope, will people be attracted to dig jade.
