And, yeah, unintended uses are usually prime locations for security breaches. For a long time (maybe still?) metadata on pictures that people post would reveal far more than people meant. Thumbnails of cropped pictures, even.
Military tech is always a decade ahead of civilian, that's why the US has easily won every armed conflict they've entered into in the past 50 years
For nuclear energy, this might be true. But for nearly any other topic I’m very skeptical.
That's just false. Ok, maybe you don't count Vietnam, because the US "entered" there in the '60s, but Afghanistan was a sure loss and I'd say the same for Iraq (seeing how it's now in Iran's sphere of influence, which it wasn't under Saddam). Yes, they might have won some tactical battles, most probably all of them, come to think of it, but the wars themselves were lost.
Read like sarcasm to me.
When two armies fight each other, what determines who gets power-gapped is the way each military operationalizes new technology. The United States defense sector does an excellent job of staying on top of new advancements, but when you examine the Cold War and WWII, most of America's tech is civilian-grade but implemented with world-class logistics and command/control.
