Very interesting post, who could honestly claim that we have an imperative role in human evolution.
I can this though, when we discover to much, it will probably all end. (for people anyway)
And I don't mean discovering new ways of talking to someone across the planet, or flying to mars and having a picnic, I mean when we discover things, or percieve more, I mean, do you know what you are looking at right now?
Perhaps that is our fate, ask questions, and destroy ourselves doing it.
