The greatest value of drone technology is that it can reach places that are difficult for humans to access.

I don't sing because I'm happy. I'm happy because I sing.

我为我的声音而战，我赢了。

预测未来的最好方式是发明它。

你对生活了解得越多，你就能为你的表演带来更多。

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.

Suffering ceases to be suffering at the moment it finds a meaning.
