My take on this fabulous story is he is imparting the following key lessons: 1) As smart as you think you are, or as smart as you think OTHERS are, EVERYONE goes through moments when they feel stupid, overwhelmed, and overmatched intellectually. 2) Even the smartest people are bad at some things (e.g. reading blueprints) 3) Ultimately you have to be comfortable with asking stupid questions, ESPECIALLY when people think you're smart. (Note - he didn't ask hoping he asked something smart, or provided value. You have to have the intellectual confidence to look stupid sometimes) 4) Your instincts will still help you even in situations where you are overmatched or under-prepared. Have the humility not to over rely on them, but don't hold back ideas - you never know when they might be helpful. These lessons are universal for any professional.
