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.

Markets alone won't solve all development challenges - we need smart interventions too.

The system produces needs faster than it can satisfy them.

事实是，我有一半的时间不知道自己在做什么，但我自信地去做。

创新不仅仅是技术的问题；它关乎改变人们的思维和生活方式。
