4.Ray Kurzweil, in his book The Age of Spiritual Machines, calculates that there have been 32 doublings since World War II and that the singularity point—the point at which total computational power will rise to levels so far beyond anything that we can imagine that it will appear nearly infinite and thus be indistinguishable from omniscience—may be upon us as early as 2050.
科兹威尔在他《心灵机器时代》一书中计算，从第二次世界大战以来，已经有了32次的倍增，而「奇异点」的来临（意指所有电脑运算能力都提升到一个超越想像的水准，因而彷佛具有无穷的能力，已经无异于无所不知）可能就近在2050年。
