There are lots of potential explanations for the Fermi Paradox[2]. One of the more popular theories is that we're intentionally not interacted with, for example the Prime Directive in Star Trek. Also, apparently 2001: A Space Odyssey is a rendition of the encounter of a type 1 civilization with a type 3 civilization[3]. This is along the lines of what was mentioned in the article about how earth is a young planet and that it would only take a relatively short amount of time (3.75 million years) to fully colonize the galaxy.
