The Brain and the Computer
大脑与计算机
Some recent developments in the computer industry make scientists predict that the gap between human beings and machines will be closed about the year 20000.
计算机行业的一些最新发展使科学家们预测，到大约20000年，人类与机器之间的差距将被缩小。
To understand the significance of this prediction let us compare the human brain with existing computers. The brain consumes electrical energy at the rate of 25 watts and occupies a volume of one tenth of a cubic foot. The brain houses between 10 billion and 100 billion items of information. Every brain cell is directly connected to many other cells. As a result, the cells in which information is stored can communicate with thousands of other cells.
为了理解这一预测的重要性，让我们将人类大脑与现有计算机进行比较。大脑以25瓦特的速率消耗电能，并占据十分之一立方英尺的体积。大脑储存着100亿到1000亿条信息。每个脑细胞都直接与其他许多细胞相连。因此，储存信息的细胞可以与成千上万的其他细胞进行通信。
However, the computer consumes 1000,000 watts of electrical power and occupies hundreds of cubic feet of space. Its million items of immediately accessible information. In contrast, the computer memory is like a cell of pigeonholes, with no thinking capacity and no connections elsewhere.
然而，计算机消耗100万千瓦的电能，并占据数百立方英尺的空间。它只能立即访问数百万条信息。相比之下，计算机的内存就像是一个个鸽笼，没有思考能力，也没有与其他地方的联系。
In a word, the electronic brains are hopelessly inadequate in comparison with the human brains.
总之，与人类大脑相比，电子大脑在能力上远远不足。
