Re: Can war be a good thing?
A good question. You point out technologies that seem to have been driven by war, but this brings to mind the "broken window" economic fallacy. Who knows what progress might have been made had so many lives and resources not been destroyed in acts of war? It is entirely possible that had the major wars not occurred (for whatever reason), we would actually be much further ahead in many areas of technology, although maybe not all the same ones. And this doesn't even count progress in art and the humanities.
