He used to be really smart guy at MIT. What happened?
Qiaochu Yuan : math PhD at Berkeley
Evan O'Dorney : math PhD at Princeton
Will Sawin : math PhD at Princeton + Columbia AP
Akhil Mathew : math PhD at HarvardI believe Qiaochu Yuan dropped out.
He fell in with the wrong crowd (SFBA “rationalists”), now he’s a life coach or something
QY quit in his 6th year of PhD. Many young prodigies go through the same process: In high school they are the sole superstar of their cohort. In college, they are stars with many equals. In a math PhD program where top talents in the world converge, they are just another good student and not competitive. So, they "lost interest".
