You're on a road, on foot or small vehicle, and you see a truck coming on collision course. What to do? You get out of the way. Obviously we can't deflect Earth from its orbit. This project showed we're able to deflect 'small' asteroids. In time, we may be able to deflect bigger ones. @ Some point, there will be an incoming asteroid that's too big to make it avoid collision. When (not if!) that happens, only option might be to escape into space, watch Earth being hit, and maybe return there some day. Chances are this will happen so far in the future, that humans don't exist any more, or have moved to other planets or even star systems, with Earth being just one of many homes. So... who cares. As long as we can avoid species-killing event long enough for significant numbers of us to get off this rock, our species could survive. That is, if we don't nuke ourselves first.
