I don't think this is true, if international co-operation can happen, not everyone will try to build these systems.
My point is, everyone sits on the internet and screams but Russia, but China, but no one really knows what they think about the situation because no serious discussions have begun.
I did see an interview with Geoffrey Hinton who says that he can see Chinese researchers are concerned, he reads it in mailing lists. In my opinion that is a good start because again, I don't think the CCP is stupid and they also have a lot of influence in the world.
My point is, trying to do nothing and maintaining the status quo won't end well either.
I think most people have just given up, climate change now this, it's too much for people.
