人脑和电脑的不同 Different human brain and computer

The difference between a brain and a computer can be expressed in a single word: complexity.
大脑和计算机之间的区别可以用一个词来表达：复杂性。
Even the most complicated computer man has yet built cant compare in intricacy with the brain.
即使是最复杂的计算机的人也都无法与人脑的复杂性相比。
Computer switches and comportents number in the thousands rather than in the billions.
计算机开关和comportents数的数千个，而不是在数十亿。
Whats more, the computer switch is just an on-off device,whereas the brain cell is itself possessed of a tremendously complex inner structure.
更重要的是，电脑的开关是只是一个开关装置，而大脑细胞是本身具有极其复杂的内部结构。
Can a computer think?
计算机能思考吗？
That depends on what you mean by"think".
这取决于你所说的“想的意思。
If solving a mathematical problem is"thinking,then a computer can"thinkand do so much faster than a man.
如果解一道数学题是“思考，那么电脑也能“think'and速度比人快得多。
Of course, most mathematical problems can be solved quite mechanically by repeating certain straightforward processes over and over again.
当然，大多数的数学问题都可以通过重复某些简单的过程来解决，而不需要一次又一次的重复。
Even the simple computers of today can be geared for that.
即使是今天的简单的计算机也能为这。
Surely, though, if a computer can be made complex enough, it can be as creative as we are.
当然，如果有一台电脑可以制作得很复杂，它可以像我们一样有创意。
If it could be made as complex as a human brain, it could be the equivalent of a human brain and do whatever a human brain can do.
如果它能像人脑一样复杂，那它就相当于人脑，也可以做人类大脑所能做的一切。
But how long will it take to build a computer complex enough to duplicate the human brain?
但是建立一个能够复制人脑的复杂的计算机需要多长时间呢？
Perhaps not as long as some think.
也许没有那么长的思考。
Long before we approach a computer as complex as our brain, we will perhaps build a computer that is at least complex enough to design another computer more complex than itself.
早在我们接近一台电脑作为我们的大脑复杂的，我们也许会建立一台电脑，至少是复杂的设计，另一台电脑更复杂的比自己。
This more complex computer could design one still more complex and so on and so on and so on.
这更复杂的计算机可以设计一个更复杂的，等等，等等。
In other words, once we pass a certain critical point, the computers take over and there is a"complexity explosion".
换句话说，一旦我们经过了某个临界点，计算机就接管了，而且有一个“复杂性爆炸。
In a very short time thereafter, computers may exist that not only duplicate the human brain--but far surpass it.
在此后的很短的时间里，计算机可能存在，不仅复制人脑-但远远超过它。
计算机开关和comportents数的数千个，而不是在数十亿。

如果解一道数学题是思考，那么电脑也能thinkand速度比人快得多。
