Since this this technology is used in war machines, it means it creates harm right so I think technology has become more of a bane then a boon as it harms or kill people.

Yes I agree. Tecnology is more like a boon then a bane as tecnology helps people who live in far places can communicate with each other and it helps us, teenagers to burn time by playing computer games and listening to music and go socail networking sites and blah blah blah blah blah...you get the idea right?
