没有智能手机的世界已经很难记住，但科学家预测， 在未来几十年内， 计算机将达到人脑的计算速度。

In just three decades, computers have evolved from machines where you could literally walk inside of the CPU, assuming you had government clearance, to the point where a child could play with a handheld toy, containing a microprocessor many times faster.

在短短的三十年里，计算机已经从你可以真正走进 CPU 的机器发展到一个孩子可以玩手持玩具的地步，其中包含一个微处理器，速度要快很多倍。
