Professor， the second question is from Fu Sheng， CEO， Cheetah Mobile：

“Does the human soul exist as a form of quantum or another form of higher dimensional space？“

教授，第二个问题来自于猎豹移动 CEO 傅盛，

“灵魂会不会是量子的一种存在形态？或者是高维空间里的另一个表现？”

I believe that recent advances in AI， such as computers winning at chess and Go， show that here is no essential difference between the human brain and a computer。 Contrary to the opinion of my colleague Roger Penrose。 Would one say a computer has a soul。 In my opinion， the notion of an individual human soul is a Christian concept， linked to the after life which I consider to be a fairy story。

我认为近来人工智能的发展，比如电脑在国际象棋和围棋的比赛中战胜人脑，都显示出人脑和电脑并没有本质差别。这点上我和我的同事罗杰·彭罗斯正好相反。会有人认为电脑有灵魂吗？对我而言，灵魂这个说法是一个基督教的概念，它和来世联系在一起。我认为这是一个童话故事。

Professor， the third question is from Ya-QinZhang， President， Baidu：  

“The way human beings observe and abstract the universe is constantly evolving， from observation and estimation to Newton‘s law and Einstein’s equation， and now data-driven computation and AI。 What is next？” 

教授，第三个问题来自于百度总裁张亚勤

“人类观察和抽象世界的方式不断演进，从早期的观察和估算，到牛顿定律和爱因斯坦方程式，到今天数据驱动的计算和人工智能，下一个是什么？”

We need a new quantum theory， which unifies gravity with the other forces of nature。 Many people claim that it is string theory， but I have my doubts。 So far about the only prediction is that space-time has ten dimensions。 

我们需要一个新的量子理论，将重力和其他自然界的其它力量整合在一起。许多人声称这是弦理论，但我对此表示怀疑，目前唯一的推测是，时空有十个维度。
