How do advances in technology affect warfare? How does warfare affect technology? What examples do you see in today's world?

Technology is everything, if we didn't have technology.... we wouldn't have technology..jk..
Technology never ends, we will be in need of something, so some scientist or inventor will invent something to help with that, and then you'll think, man this really isn't all that good, we could do better so they use that thing and improve on it to make it even more useful and much easier to use, and it'll never end, it'll just keep getting better and better.
And in warfare, if we didn't have technology, wars would take much longer because fighting with nothing but swords and bows, that would take forever to conquer a whole city or country, but with bombs and guns, to destroy a city all you need is one bomb, so a few seconds to drop and the city goes kaboom!! So we are always in need for more and more technology, the more we have the better, but also if we get some cool high tech machine, it won't help that much in the war because the other side would probably also have it so it would just even out again.. so ya!!!
