I had the same thought when I was 18 (now I am 19)... You can come to understand the world from your perspective... But, to have a deep and complete knowledge of how the world works, you would have to have omniprescence (the ability to transport yourself to any part of the world) and to be able to get into the thoughts of all people, observing all possible perspectives to reach a final conclusion... This just to understand the "modern world", with this you could approximate the "why" and the "how" our world works.
