(This is kinda tangential but related) I have a weird theory about humanities purpose: Assuming someone/thing created life (if life wasn't created then it truly is random chaos and we have no purpose), but if life was intentionally made then we were created for a reason. Determining what that reason was will tell us what our purpose is. The only clue we have is evolution. If we can reverse engineer the mechanisms of evolution it should give us clues about why we are here. What is evolution driving us to become? If we can figure that out we might be able to deduce what our purpose is.
I feel like one of life's huge leaps forward, on par with single->multicellular, is recognizing that these evolutionary mechanisms exist, furthering our understanding of and leveraging them. Anyway that is a long ramble to say it sucks that we as a species cannot really touch any kind of eugenics without genociding eachother.
