人は誰でも、孤独を感じるときがある。

理论很少被更好的理论推翻，更多的是被失去兴趣的实践者抛弃。

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

我不需要一个团队，我自己就是团队。
