本文探讨了人类大脑与现有计算机系统的对比。大脑消耗25瓦电力并存储100亿到1000亿条信息，每个细胞都能直接与其他多个细胞相连；而计算机则消耗100万瓦电力且占据数百立方英尺的空间，其存储单元不具备思考能力且相互间没有连接。

Some recent developments in computer industry make scientists predict that the gap between human beings and the machine will be closed by the year 20000.

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 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. In contrast, the computer consumes 1,000,000 watts of electrical power and occupies hundreds of cubic feet of space. The

computer memory is like a cell of pigeonholes, with no thinking capacity and no connections elsewhere.

In a word, the electronic brains can hopelessly succeed in comparison with the human brains.
