6、的转换器只是一个开关装置，而大脑细胞本身就具有极其复杂的内部结构。电脑会思考”吗?这就要看你所说的思考”是指什么了。如果解一道数学题是思考” ，那么电脑会思考” ，而且比人脑快得多。当然，绝大多数数学题都可以通过一遍一遍机械地重复简单的程序而得到解决。即使是现今简单的计算机也能做到这点。然而，电脑如果能造得够复杂，它也能和我们一样富于创造力。如果它能造得同人脑一样复杂，它便能与人脑相媲美，并能做到人脑能做到的一切。但是，要造出一个与人脑一样复杂的电脑要花多长时间呢 ?或许 不会像有些人想象的那么长。在造出与人脑一样复杂的电脑之前，我们也许可能要先造出一个 电脑，它复杂得至少能设计出比它本身更复杂的电脑。那个更复杂的电脑又能再设计出比自己更复杂的电脑，如此反 复。换言之，我们一旦突破了某个极点，电脑将盛行起来，并导致复杂性爆炸不久，电脑将不仅复制人脑，而且将远远超越人脑。文章
