Would it even be possible to ban open weight models, given all the ways they can be used in finetuned models or online services, also in 3rd countries?
Not only the initial strength is important but also the susceptiveness to crack growth during many years of stress. No idea how this structure would perform on this aspect.
See the end of the article, after further research quantum gravity could be simulated on a quantum computer. The links between research on quantum computing and quantum gravity are fascinating anyway!
