This is a very well written post and it surely has a deep message. Humanity has a bad record in being responsible with new and dangerous technologies so this is surely a warning that needs to be kept in mind.
But in the end, I do think we should seek as much knowledge and understanding and knowledge itself should not be viewed as something negative by itself. If there is an underlying truth in something, we would always be better off knowing it, even if it would be something unsettling. The problems come with things that can be abused.
