That’s one of the reasons for the turbulent times. Let’s face the truth, most of the defense can easily be used for offense and given the state of online security every progress gets into the wrong hands.
Maybe it’s time to pause to make it more difficult for those wrong hands.
Yes, many defensive uses of technologies can be used for offense. When I say defense, I also include offense there as I don't believe you can just have a defensive posture alone to maintain one's defense, you need deterrence too. Personally I'm quite happy to see many in Silicon Valley embrace defense-tech and build missiles (ex. recent YC co), munitions, and dual-use tech. The world is a scary and dangerous place, and awful people will take advantage of the weakness of others if they can. Maybe I'm biased because I spent a lot of time in Eastern Europe and Ukraine, but I much prefer the U.S. with all our faults to another actor like China or Russia being dominant
