I wanted this to be thought provoking, but for a physicist to open with, "the acceptable risk of catastrophic meltdown for a nuclear power plant is roughly one in a million", just seems sad. It is a phrase without meaning.

   Is it per plant? there aren't a million.
   Is it per year? notably have been at least 2 major ones (arguably 7).

That said, the rest of the analysis and proposal also greatly disappoints me. The idea that the current administrations of US and China could do anything constructive seems hilarious. They're so paranoid and self-serving they couldn't come together, even if there was an alien invasion. Then the idea that LLM safety is somehow as easily traceable as nuclear isotopes and bomb tests seems equally ludicrous. I am sad.
