人类一直在追求长生不老，但长生果真如此美好吗？如同技术奇点，当我们越来越接近这个临界点，它会对人类的事物产生越来越大的影响。而当此转捩点来临的时候，影响不仅仅关乎个人，旧的社会模式将一去不复返，新的规则开始主宰这个世界，我们对于“人”的认识将重新定义。但当它最终来临的时候，也许仍会出人意料并且难以想象，人类应当反思它会带来怎样的后果，而同时人类将付出什么代价。

From ancient times to the present, and from ancient Chinese alchemy to modern life extension plan, human beings have been pursuing immortality. Is the eternal life desirable? When it comes, the impact is not just about the individual. The old social model will disappear forever，and the new rules will begin to dominate the world. Our understanding of "people" will be redefined. When it finally comes, it may still be unexpected and unimaginable, so we should think about the consequences.
