If we use great inventions for good, well, then all is fine. But somebody always has to turn everything into destructive weapons. Even the great Leonardo da Vinci invented weapons of mass destruction. And yet, I have read that he once bought all the caged birds in a market and let them loose. My kind of hero. A mixture, though.
Bows and arrows were good though, long ago, a great invention, as hunter gatherers ate meat. I am sure that is also where harps developed from. Twang! Sounds good. Put another string on and a third, sounds even better!
