The Brain and the Computer
大腦與計(jì)算機(jī)
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.
計(jì)算機(jī)行業(yè)的一些最新發(fā)展使科學(xué)家們預(yù)測(cè)，到大約20000年，人類與機(jī)器之間的差距將被縮小。
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.
為了理解這一預(yù)測(cè)的重要性，讓我們將人類大腦與現(xiàn)有計(jì)算機(jī)進(jìn)行比較。大腦以25瓦特的速率消耗電能，并占據(jù)十分之一立方英尺的體積。大腦儲(chǔ)存著100億到1000億條信息。每個(gè)腦細(xì)胞都直接與其他許多細(xì)胞相連。因此，儲(chǔ)存信息的細(xì)胞可以與成千上萬的其他細(xì)胞進(jìn)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，計(jì)算機(jī)消耗100萬千瓦的電能，并占據(jù)數(shù)百立方英尺的空間。它只能立即訪問數(shù)百萬條信息。相比之下，計(jì)算機(jī)的內(nèi)存就像是一個(gè)個(gè)鴿籠，沒有思考能力，也沒有與其他地方的聯(lián)系。
In a word, the electronic brains are hopelessly inadequate in comparison with the human brains.
總之，與人類大腦相比，電子大腦在能力上遠(yuǎn)遠(yuǎn)不足。
