The idea that we will make a society where literally everybody is graded, the good at the top, bad at the bottom, exactly done as it should be, is impossible. There are simply too many random factors: accidents, accidents of birth, accidents of things dropping on people's heads, illnesses, etc. We will never get to grade them, never get to grade people as they should.
这种我们能创造一个每个人的能力都忠实地被分级，好的就到顶端，坏的就到底部，而且保证过程毫无差错，这是不可能的。这世上有太多偶然的契机，不同的机运，出身，疾病，从天而降的意外等等，我们却无法将这些因素分级，无法完全忠实的将人分级。
