I'd say we go back to the proposed idea of having nuclear launch codes in someone's chest cavity. That's a good way to keep a human always "in the loop" , but in all seriousness it seems kinda ironic that possibly one of the safest options would be to "analoguize" (in case it isn't already I'm.not knowledgeable enough) most of the chain of command and capacities of a nuclear launch. But then again misinformation inside the organization could provide a human failure in the system ... 🤷‍♂️
