Interesting that he doesn't seem to debate or reconcile how painful he found working on his PhD, with his decision to rejoin academia. He makes the persuasive point that he doesn't have the freedom to pursue long-term research in the industry, but he documented all the trade-offs inherent in that freedom in 'The PhD Grind'.

Is it just that he's on the other side of the advisor-student power-balance? Or that he has the experience and skills to negotiate them better?
