There is none. Science is discovering what is possible. Technology is changing something from possible to doable. Once the possibility of something is made clear (if not the exact path toward it - the do-ability), people will start rushing for it - if only out of fear that someone else might have it while they themselves do not. At least nuclear technology has the downside of being very expensive and large-scale (so few players) to produce, and being pretty obvious when it's actually used. Other things that are becoming increasingly possible (but still not doable) - like modified viruses that only target people with a specific DNA profile - will be a lot easier to hide, both their production and their usage. Same thing with AI.
