Some time ago, researchers at Stanford University designed an AI , which claims to be able to judge a person's sexual orientation based on a photo of his or her face, with an accuracy rate of 81 percent for judging men's sexual orientation and 74 percent for judging women's sexual orientation.

How does it work? The same thing, big data and algorithms.

The AI can tell at a glance whether you're straight or crooked by y analyzing facial features in more than 35,000 photos from U.S. dating sites, as well as based on big data and visual analytics.

At the Wuzhen Internet conference in the past two days, tech gurus have coincidentally conceptualized the future of AI. For example, Jack Ma believes that although AI will replace some people's work, but we have to believe in human creativity, there will be new jobs that need human beings; Google CEO Sundar Pichai hopes that AI can make computers adapt to human beings.

It is undeniable that AI will play a more important role in human society in the future, just as Prof. Winston of the Massachusetts Institute of Technology (MIT) believes: AI is to make computers to complete the intelligent work that only human beings can do in the past. But fortune-telling and palmistry, these metaphysics, should not be included.
