Authenticity and respect go to those who stick to their own specific field of work. For example, I am a Biologist and my work is the understanding of human nature - that's where I place all my attention. I know nothing revelatory about modern physics - I know nothing revelatory about mathematics - I know nothing revelatory about architecture - I know nothing revelatory about any field of understanding except for the ones directly related to biology. It doesn't mean that I cannot learn about other fields - I can, but every human has his or her own distinct knack, and mine is understanding humans - understanding how and why they think, what they think - how and why they feel, what they feel - how and why they behave, the way they behave - how and why they perceive, what they perceive.
It is usually unbearably painful to read a book by an author who knows way less than you do, unless the book is a novel.
