大多数人宁愿躲避而不去想了。就连生命伦理学这个领域，也宁可去回答另一个问题：“有什么是必须禁止的？”我们可以用活人做基因实验吗？用流产的胚胎？用干细胞？克隆羊符合伦理道德吗？克隆黑猩猩？克隆人类呢？虽然这些问题确实都很重要，但如果还认为我们能够踩刹车、阻止让人类升级成另一种不同的物种，可能就太天真了。原因就在于，虽然这些计划各有不同，但追根究底还是回到了对长生不死的追求：吉尔伽美什计划。不管是问科学家为什么要研究基因组，还是为什么要把大脑连接到计算机，或者为什么要在计算机里创建一个心灵，十有八九，都会得到相同的标准答案：这么做是为了治疗疾病、挽救人的性命。想一想，为了治疗精神疾病，就说要在计算机里创建一个心灵，难道不会觉得太小题大做？但就是因为这种标准解答太具正当性，所以没有人能够反驳。正因如此，吉尔伽美什计划正是现在科学的旗舰，能够让科学所做的一切都有了正当的理由。创造科学怪人的弗兰肯斯坦博士，现在就坐在吉尔伽美什的肩膀上。阻挡不了吉尔伽美什，我们也就阻挡不了弗兰肯斯坦博士。
现在我们唯一能做的，就是影响他们走的方向。既然我们可能很快也能改造我们的欲望，或许真正该问的问题不是“我们究竟想要变成什么”，而是“我们究竟希望自己想要什么”，如果还对这个问题视若等闲，可能就是真的还没想通。
