And I really think there's a fundamental difference, if you sort of look into the future, between a humanity that is a space-faring civilization, that's out there exploring the stars, on multiple planets, and I think that's really exciting, compared with one where we are forever confined to Earth until some eventual extinction event.
而我真的觉得有一个基本的区别， 如果你想象下未来， 在太空文明中的人类， 他们会出去探索星球，不同的星球， 而我觉得那真是激动人心， 比起我们永远的困在地球上 直至灭绝来说，确实如此。
