主题语境:信息时代
In many aspects,nowadays business environment has changed greatly since the late 1980s.The end of the cold war completely altered the very nature of the world’s politics and economics.In just a few short years,globalization has started a variety of trends with profound consequences:the opening of markets,true global competition,widespread deregulation (解除政府对……的控制) of industry,and an abundance of accessible capital.We have experienced both the benefits and risks of a truly global economy,with both wall street and main street (平民百姓) feeling the pains of economic disorder half a world away.
At the same time,we have fully entered the information age,starting breakthroughs in information technology,which have irreversibly altered the ability to conduct business unconstrained by the traditional limitations of time or space.Today,it’s almost impossible to imagine a world without intranets(内联网),e-mail,and portable computers.With amazing speed,the Internet is profoundly changing the way we work,shop,do business,and communicate.
As a consequence,we have truly entered the post-industrial economy.We are rapidly shifting from an economy based on manufacturing and commodities to one that places the greatest value on information,services,support,and distribution.That shift,in turn,attaches great importance to “knowledge workers”,a new class of wealthy,educated,and mobile people who view themselves as
free agents in a seller’s market.
Beyond the field of information technology,the increasing pace of technological change in virtually every industry has created entirely new business,wiped out others,and produced a great demand for continuous innovation (创新).New product,process,and distribution technologies provide powerful levers for creating competitive value.More companies are learning the importance of destructive technologies——innovations that hold the potential to make a product line,or even an entire business segment,virtually outdated.
Another major trend has been the consumer and business markets.There’s a growing appreciation that superficially similar groups of customers may have very different preferences in terms of what they want to buy and how they want to buy it.Now,new technology makes it easier,faster,and cheaper to identify and serve targeted micro-markets in ways that were physically impossible or prohibitively expensive in the past.Moreover,the trend feeds on itself—a business’s ability to serve sub-markets fuels customers’appetites for more and more specialized offerings.

主题语境:人工智能
Computers have become so smart during the past 20 years that people don’t think twice about chatting with digital assistants like Alexa and Siri.But that required hard work from computer scientists like Yoshua Bengio,Geoffrey Hinton,and Yann LeCun.They tapped into their own brainpower to make it possible for machines to learn like humans,a breakthrough now commonly known as “artificial intelligence”,or AI.
Their insights and persistence were rewarded with the Turing Award,an honour that has become known as technology industry’s version of the Nobel Prize.The award marks the latest recognition of the instrumental role that artificial intelligence will likely play in redefining the relationship between humanity and technology in the decades ahead.
Over the past 30 years,Mr.Bengio,Mr.Hinton,and Mr.LeCun have mostly worked separately on
technology known as neural (神经的) networks.These are the electronic engines that power tasks such as facial and speech recognition,areas where computers have made huge improvements over the past decade.Such neural networks also are a key part of robotic systems that are automating a wide range of other human activities,including driving.
Their belief in the power of neural networks was once looked down upon.“For a long time,people thought what we were doing was nonsense,”Mr.Hinton said in an interview with TheAssociatedPress.“They thought we were very misguided and what we were doing was a very surprising thing for apparently intelligent people to waste their time on.My message to young researchers is,don’t be put off if everyone tells you what you are doing is silly.”
While the AI revolution is raising hopes that computers will make most people’s lives more convenient and enjoyable,it’s also arousing fears that humanity eventually will be living at the mercy of machines.Mr.Bengio,Mr.Hinton,and Mr.LeCun are also concerned that AI technology might be developed into weapon systems that wipe out humanity.
But they are far more optimistic about the other prospects of AI—empowering computers to deliver more accurate warnings about floods and earthquakes,or detecting health risks,such as cancer and heart attacks,far earlier than human doctors.
