> Do Americans even believe that US policy is likely to steer development in a way that’s safe and beneficial for humanity?

No, at least not outside of this forum.

We all mostly think these models and US policy are going to drive the exact opposite of that. Wealth will continue to get extracted and funneled to the top, and the rest of us are going to be left with the scraps and left to die while what little social safety nets we had continue to get eroded away alongside losing our jobs.
