When you see the kinds of things that are developed in the name of "defense" it's easy to see how AI "safety" could become a similar sort of doublespeak.
AI safety already is double speak. The primary meaning is "safety" for investors who don't want to be associated with something distasteful. The other meaning is basically a thin cover.
Well you can look forward to worse, give it another decade and Lockheed Martin will be extolling their commitment to AI safety while announcing their new generation of fully autonomous kill drones. For defense, of course.
