I know it sounds crazy - but if there's even 0.1% chance that some models are so good that they can be used to hack into people's bank accounts - I, as the government, would not want that model to be publicly accessible. I would also request other countries to come to the table and sign this NPT(for AI).
Public will still have access to smaller models (like guns etc) up to Opus 4.8 etc but anything bigger than that is sooo good that it's dangerous. Nuclear also has benefits but the governments consider the worst when making policies rather than the best.
I am not touting Mythos as the god model but I wonder if the policy will move in this direction.
