Humans tend to be terrible at being proactive, but we respond fast during disasters. I think Eric Schmidt's prediction is most likely: we won't take reasonable action to control access until there is some kind of disaster. We hope it's small enough to not kill too many people, but large enough to cause widespread panic. We hope that it happens soon, because if it happens two years from now, it's likely too late. AI will be so advanced that we have no hope of understanding its motivations. All reasoning will be completely opaque to us. It will be building newer and better versions of itself using moral frameworks it itself decides. We will be completely out of the loop, and potentially superfluous to its goals.
Even if not for the sake of avoiding a mitigable disaster, there's a huge benefit in simply pacing development so as to not completely freak out society as they stare down the barrel of mass job market changes without time to adapt or prepare. Nobody wants to live in a world where they might wake up in a month and find their entire industry has been automated overnight.
We've tackled much bigger global issues successfully in the past and the US still has enough pull that it could probably get most western nations to march in line. It seems like the biggest issue is belief in the right of governments to govern.
People (well, public discourse) have got extremely bad at dealing with forseeable risks and their mitigation. You can see this in things like climate change and vaccination, but also in discussions around regular crime, food poisoning, industrial accidents, and so on.
Nothing will improve until something explodes on live TV. And it has to be something important, which means it has to be in California or New York.
