So long as we're throwing wild personal opinions around, here is my own. I don't believe that the military or government has any computer technology that is significantly more advanced than what we are seeing in known academic research laboratories and private research programs. Even if they wera able to create a super-quantum computer, the advantage would be so short lived against the rest of the world following behind, I don't think it would even make sense from a budgetary and strategic point of view. I remember in the 90's there was a lot of speculation about the kind of incredible computer technology that the government and military must have had, because we were coming from a time when the highest technology traditionally came from government and military programs. That's not really true anymore, and it wasn't really true then either. As it turns out, the government did not have any computer technology that was superior to technology held by any number of academic and private institutions and I don't think this has changed, especially in these economic times. I think this idea is no different than the formerly widely held belief that the american military is so advanced and powerful that they would certainly walk all over any technologically inferior country like say, Vietnam, Iraq or Afghanistan with no trouble whatsoever. It's all smoke and mirrors, anyone remember the Aurora aircaft? Off the top of my head the only project I can think of that succeeded in creating a super technology well ahead of the curve, was the Manhatten project, but even that supremacy was very short lived. Even the internet, their greatest and most successful endeavor, did not experience its renaissance until it was opened to public and private institutions. They simply cannot compete on their own aginst that open market, not anymore.
I was in the Army 2003-2007. Saw a lot of things. Nothing of which made me think our (my) government was all powerful technology wise, when the insurgence were taking out our armored assets with homemade explosives.
Friend of mine was military intelligence with top secrete clearance. While he did not divulge anything to me (rightly so) he did say the world was a lot more mundane than what people would like to believe...
