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 YoshuaBengio, 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 honor 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 The Associated Press. “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.
