This video is a sublime but poignant reminder of the capabilities of mankind. It reminds me that we must responsible and careful in our actions and pursuits. It scares the crap out of me because I do not trust the majority of people in the world who have this power at their disposal. We are going to obtain even more potent capacities of effect on this world and we must use them for altruistic good and progress, and abandon the pursuits of power, and dominance.
I believe this video is evidence that we will not find that we will be challenged in creating change. Our challenge will be in what we decide to apply change to.
