The other Authors would probably say something along the lines of how even if technology advances to a point where there can be no war because we as individuals are so enveloped in our own sphere of influence that we must begin a war with ourselves to become social creatures again. Because no matter how hard you try, we are social creatures to our core and this is how we survived for so many years. It also suggests that the problems we are facing today are caused by science and technology, if we are to stay in this track we will surely develop more problems as time goes on. In short; science and technology will answer a few social problems, but will end up making just as many in the process.
As with everything that humans have worked on, changed, or improved, there will always be negative side effect – for example; living in close knit cities creates protection from the beasts of the wild, but it also makes hygiene and crime problems. I think these repercussions we face are required for us to keep improving something that we strive to be great. We made jobs that dealt with the waste and jobs that kept criminals at bay. This is a great example of how time and dedication will continue to make social and environmental problems a reality, but also a way for people to step up and make the world a better place.
