But isn't know-how how you got to this world view of yours? If you could do it, so can others, and technology does improve the global know-how. Even if some also use it to "control, destroy and sow despair" as you say. There would be people doing that anyway, as history shows. The printing press was the same, but I think we can all agree that the net result is positive. So is, in my view, the modern "tech".
