A computer program does what you tell it to do, not what you want it to do.

The stream of thought is the stream of life solving its problems.

黄金法则就是没有黄金法则。

Your smarts will come in handy because you will travel in a land of marvels. We humans -- plodding as we are -- will astonish ourselves. We'll invent ways to generate clean energy and a lot of it. Atom by atom， we'll assemble tiny machines that will enter cell walls and make repairs. This month comes the extraordinary but also inevitable news that we've synthesized life. In the coming years， we'll not only synthesize it， but we'll engineer it to specifications. I believe you'll even see us understand the human brain. Jules Verne， Mark Twain， Galileo， Newton -- all the curious from the ages would have wanted to be alive most of all right now. As a civilization， we will have so many gifts， just as you as individuals have so many individual gifts as you sit before me.

我们实现明天的唯一限制将是我们今天的怀疑。

那些疯狂到认为自己可以改变世界的人，才是真正改变世界的人。
