英国科幻作家道格拉斯·亚当斯有一个很有名的“科技三定律”：

(1) Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.

(2) Anything that's invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.

(3) Anything invented after you're thirty-five is against the natural order of things.

翻译过来即是：

（1）任何在你出生时已经有的科技都是稀松平常的世界本来秩序的一部分。

（2）任何在你15-35岁之间诞生的科技都是将会改变世界的革命性产物，并且你可能会以此为生。

（3）任何在你35岁之后诞生的科技都是违反自然规律要遭天谴的。

这一“科技三定律”可以用来解释不同人群对于新事物的看法。
