The concerns are legitimate but the proposals are nothing more than a stopgap solution.
If US wants to maintain engineering superiority, we needs to invest in it -- education, research and infrastructure. Bring in top researchers across the globe and not make it harder.
China is building infrastructure for the future generations and investing in growth sectors while the US is cutting of university grants and spending billions on a war without clear path to resolution.
I don’t disagree but the timeline for Dario’s concerns are quite short. Open weight models could feasibly lead to serious bio safety concerns in the next year or so while the US’ current issues are going to take a long time to work through.
China is also financially repressing their people to build often useless infrastructure projects to be fair they are also not the good guys.
