I'm the last person to accuse the US of being sanely-governed, but you'll forgive me for not worrying any more about a conspiracy of billionaires with access to US nuclear arsenal all agreeing that the best way to ensure they live long and healthy lives unencumbered by vengeful proles/superpowers is to nuke the top 500 cities than I do about Roko's Basilisk or the end of the world as predicted by the Aztecs...
I'm not worried about the billionaires, I'm worried about the models they are empowering.
I'm even less worried about AI models obtaining corporeal form to stride into the US nuclear bunkers to launch missiles against their own power infrastructure and datacenters...
If you think that is what is required, you aren't keeping up.
Okay then. What does the infrastructure around launching a nuclear weapon look like?
