I agree. I found that the best part was that founders went on length answering the questions. The text could be verbatim or it could be how the book is edited.

I usually find interviews annoying as the interviewer interjects a lot, breaking the chain of thought, diverging the discussion or some times cutting them off to inject their own opinions.

This book I thought had none of that. And I learned a lot reading it.

As for PG's essay, I think I came across this exact content some place else (my memory fails me).
