Well from your perspective as a physicist i am in agreement with you. But unfortunately the world is not the one you know.. The real world is made of people and entities that take this kind of technology and power and use it for no good. This is the one i am talking about. As you know there are a myriad of examples as to why we should not be messing with our world. I don't believe it is up to us to figure this out as we are merely here as visitors, and what we learn here is irrelevant in the spirit of things. But again, i guess from your perspective, this means nothing. The internet itself is safe as well, but its application allows for more harm than good to be done, imagine a collider. Not trying to discredit anything, but again, humans are destructive and arrogant by nature. Cheers
