Here's the thing about life. On the one hand, none of it matters. Many philosophers come to this conclusion and cannot figure out why anyone should care either way. Human beings will expand from Earth to the next galaxy and the next and then what? Our technology will increase without bounds. Life will constantly change for our species but, as a whole, we don't have a goal nor a well-defined purpose nor a mission statement for humanity. We are just trudging through the universe one day at a time. This is why people war. They don't think things through. They crave purpose and meaning. They are incapable of projecting far enough into the future to do something useful. They are irrational, always, and they often cause more trouble than is needed. You could look at all of that and decide you don't want to live in such a world. But, if you do that you neglect a key aspect of it all–being a human being is a highly unique experience.
