I can’t remember the history exactly but isn’t Cal Newport the one who became famous for being a postdoc who was super prolific while still rabidly being 9-5 40 hour schedule ? Used to piss me and my friends off so much as if WE wanted to burn up by working more as opposed to the environment forcing it on us. And if I recall correctly, he recanted on it after becoming a professor and realizing that can’t actually work if you are truly responsible for things in a lab? Or something to that tune? Please correct me my memory is frail on this.
