说明：  人脑神经网络和计算机神经网络的不同在于，人脑可以解决通用性和跨领域的问题，而计算机神经网络只能解专门的问题，所以哪怕阿尔法狗在围棋界孤独求败战胜了所有男人，但他也不能识别出站在他面前的两个女生谁更漂亮(The difference between human brain neural network and computer neural network is that human brain can solve universal and cross domain problems, while computer neural network can only solve specialized problems. Therefore, even if alpha dog defeats all men alone in go, he can not identify the two girls standing in front of him who is more beautiful)
