The kinds of things I'm thinking about are the various countries nuclear arsenals might not be safe from actors with very advanced AI. This I think is the potential source of existential risk, in my opinion. So it could hurt a hell of a lot.
So I'm of the responsible disclosure point of view. You ask "Would releasing AI advancement X mess up someones security/economy". If so, you help them patch it before releasing it to the general public.
The majority of advancements aren't like that and they won't be for a while.
