Below, let's briefly review the top ten scientific and technological failures that have occurred since 20 17:
1. The human Go masters collectively fell.
20 17 In May, at the Weiqi Summit in Wuzhen, China, AlphaGo, an artificial intelligence program of Weiqi, played against Ke Jie, the No.1 Weiqi champion in the world, with a total score of 3-0. It is recognized in Weiqi that AlphaGo has surpassed the top level of human professional Weiqi. In the ranking of professional Go in the world published by GoRatings website, its grade score has surpassed that of Ke Jie, the first player in human beings.
As early as last March, AlphaGo and Li Shishi, the world champion of Weiqi and a professional nine-stage chess player, also won the man-machine war with a total score of 4:/kloc-0:, which made AlphaGo the first artificial intelligence program to defeat human professional Weiqi players and the first program to defeat the world champion of Weiqi.
After the man-machine battle with Ke Jie, the AlphaGo team announced that AlphaGo would no longer participate in the Weiqi competition, and Dr. Huang Shijie, a scientist of AlphaGo's research and development company DeepMind, immediately posted AlphaGo's "farewell message" on social media. He said that DeepMind and I will switch to other projects, which also marks the curtain call of AlphaGo's research on Go.
On the evening of 65438+February 1 1, DeepMind launched the AlphaGo teaching tool in official website. Ke Jie, the first person in Go in the world today, then forwarded this Weibo and commented: "Learn Go again."
2. The second and third lines * * * enjoy the collective collapse of bicycles.
After the crazy economic development of bike-sharing in the previous year, Wukong Bicycle, which had been in operation for only five months on June 13 this year, withdrew from the bike-sharing market for lack of funds and announced that it would stop operating, which seems to have started the collective bankruptcy tide in the second, third and * * bike-sharing on June17.
After a lapse of eight days, 3Vbike, which was mainly developed in third-tier cities, announced that its bicycles had been stolen, and withdrew from the market due to management problems, and stopped operating on June 2 1 day. In August, it was reported that bicycles were "running" in Nanjing-machi, and it was later confirmed that they stopped operating due to the break of the capital chain.
Subsequently, the "Little Blue Bike", "Cool Bike Riding" and "Xiaoming Bike" located at the second stage of bicycle enjoyment in * * * were also doomed, and they all announced that they would stop operating. A number of * * bicycle enjoyment groups have fallen into the tide of bankruptcy, which has also caused the previously hot * * bicycle enjoyment industry to enter the cold winter overnight.
3. False demand * * * Enjoy the wave of economic collapse
Since "Didi" and "* * * enjoy cycling" have been popular with the capital, various projects with * * * enjoy the economic coat have emerged one after another, such as * * enjoy the charging treasure, * * enjoy the umbrella, * * enjoy the gym, * * enjoy the air conditioner and so on. But there are few real winners. The most representative projects of 20 17 may be lotte, PP charging, modern vitality and sleeping space.
Judging from the current news, seven charging treasure enterprises, such as Hippo Charging, Bao Xiao Charging, Chuangdian, Discharge Technology, pp Charging, Lotte Charging and Bubble Charging, have reached the project liquidation stage. It is worth noting that Hippo Charging, which was the first to fail, received tens of millions of angel rounds of investment led by Meihua Angel in April this year, and the failure of these enterprises seems to indicate the real arrival of the economic collapse tide of pseudo-demand.
