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.

写作就是直面过去留下的幽灵。

时间最美的地方在于你无法提前浪费它。明年，明天，下一个小时都在等待着你，它们就像你从未浪费或误用过一刹那的生活一样完美，不受玷污。如果你愿意，你可以每小时翻开一个新的一页。
