What are the hottest high-tech start-ups in Silicon Valley in the 2015?

In Silicon Valley, we are very enthusiastic about the opportunity to talk about entrepreneurship, I also through their own some observation and accumulation, saw a lot of recent years, the emergence of the popular start-up companies. I'm giving you a list of the world's Wall Street web site, the global start-up company financing Scale (http://graphics.wsj.com/billion-dollar-club/). Its original title is billion startup club, I also shared last year's domestic lectures, less than a year, as of January 17, 2015, now ranked and scale has undergone a great change. At first, valuations reached 7 in 10Billlon, a year ago without a home. The second first is the Chinese household name of millet, third, the top 20, the vast majority (80% in the United States, in California, in Silicon Valley, in San Francisco!) such as Uber, Airbnb, Dropbox, Pinterest. There are a number of similar models successful, such as Flipkart is the Indian market Taobao, Uber and Airbnb are the areas of shared economy. So you can still find the next big opportunity in Mobile (Uber), large data (Palantir), consumer-level Internet, communications (Snapchat), paying (Square), O2O app. I've been interviewing and feeling about the environment in many of these companies. Is there such a large number of high valuation companies, does it mean there is a big bubble? Looking at so many high valuation companies, many people feel very crazy, this is not a big bubble, the bubble is not broken, is a lot of people's questions. I think in Silicon Valley, where it's a dream place, where investors encourage entrepreneurs to do the same, it also encourages bubbles, and many projects are valued at 2, 3 times times in a few months, like uber,snapchat on the scale of their huge financing. So this is the "emerging technology hype" cycle, which classifies technologies in terms of technical maturity and expectations, as mentioned in the Silicon Valley business incubator YCombinator course how to start a startup. Innovation Bud Innovation Trigger "," the peak peak ofinflated expectation "," downward expectations to the low point trough of disillusion "," return to the ideal slope ofenlightenment "," productivity platform plateau of productivity ", the more to the left, the technology is about trendy, the more in the conceptual phase; The longitudinal axis represents the expected value, people for the new technology usually with the understanding of in-depth, expected to continue to heat up, accompanied by media hypeto the top; it is expected to cool down for technical bottlenecks or other reasons, but when technology matures, expectations are rising again, accumulating users, and then reaching a healthy track of sustainable growth. The comparison between this year and last year shows that the concepts of IoT, self-driving cars, consumer-grade 3D printing, and natural language quiz are at the top of the hype. And big data has slipped from the top, NFC and cloud computing near the bottom. What is the trend of High-tech entrepreneurship in the future? I'm going to mention a recent movie, "Imitation Game", the founder of computer logic, Alan Turing (named after the computer's highest award), who made a remarkable contribution to the victory of World War II by deciphering the German code, creating a Turing machine Save the lives of tens of millions of of people, but in that era because homosexuality was sentenced to chemical castration, suicide ended a brief 42-year-old life. One of his great contributions was in the development of artificial intelligence, and he presented the Turing Test (Turing test) to test whether a machine showed an equivalent or indistinguishable intelligence. We are now back to today, artificial intelligence has made great progress, from expert system to statistical learning, from support vector machine to neural network depth learning, each step to lead the machine intelligence to the next ladder. Dr. Wu, senior scientist at Google (the beauty of mathematics, the top of the wave author), he puts forward three trends in current technology development, first, cloud computing and and mobile Internet, which is being carried out when; second, machine intelligence is now beginning to occur, but many people are not aware of the impact on society; The combination of large data and machine intelligence, this is the future, will certainly happen, there are companies doing, but not too large scale. He thinks the future machine will control 98% of the people, and now we have to make a choice, how to become the remaining 2%? "Exclusive" WU: The Future machine will control 98% of the people. Kai-Fu Lee in the 2015 New Year Outlook also put forward in the next five years the Internet will bring huge entrepreneurial opportunities.
