From the submitted public comments on the government website, I learned that Molnupiravir's mechanism of actions seems to be inducing mutations in the virus. Some of the comments bring up the possibility that this might lead to greater probability of new variants emerging. I'm not sure how probable this is, but it seems something worth considering.
In regards to AI, what about regulation of advanced GPU manufacturing, to try to stop the creation of increasingly powerful GPUs? The US currently has regulations against exporting powerful chips to China; maybe an international agreement (between US, EU, China, and Russia) would be possible to globally prohibit manufacture of chips that exceed certain specs? I think something like this would be eventually be necessary, because regulation of AI training would be impractical to enforce if bad actors can easily acquire and run the hardware needed for such AI training.
