History is alive in the stories we tell.

Come,my friends,Tis not too late to seek a newer world,For my purpose holds to sail beyond the sunset，And though we are not now that strength which in old days moved earth and heaven,That which we are, we are;-- One equal temper of heroic hearts, Made weak by time and fate, but strong in will. To strive, to seek, to find, and not to yield。

【译文】不要轻信那些所谓特别正直的人，也要防备那些标榜仁义却不仁义的人。山里有长得笔直的树，世上却无正直的人。

在人工智能上度过的一年足以使人相信上帝。
