It will be interesting to see how warfare will be conducted between nations with strong military, and strong computing capabilities, especially with how much more technology has been integrated into our daily lives, and structure. Take Canada for example, last year a bad BGP update caused a nationwide communications outage for those using Rogers (because for some reason our government won't do anything about our ISP oligarchy, and we practically get only 3 choices for internet providers). That outage even though it lasted a day impacted so many people, and affected many core services like hospitals, and effected many businesses. That through accident too, I can only imagine what intentionally attacks on national IT infrastructure would be like, and how much chaos it would cause.
