I know it is a difficult subject but whichever country gets access to this superintelligence will certainly use it for "safety" reasons. Sutskever has lived in israel and now has a team there , but israel doesnt strike me as a state that can be trusted with the safety of the world. (many of the AI business leaders are of jewish descent, but not sure if they have half their team there).
US on the other hand is a known quantity when it comes to policing the world.
Ultimately the only safe AI is going to be the open one, and it will probably have a stupid name
