AI "killing all humans" is the viral soundbite that's connecting with the masses ("actualizing" itself to create weapons of mass destruction, etc). It's also the perfect punching bag for strawman-style takedowns of anti-doomers because it's so wrapped in hypotheticals. A more pressing practical question is simply: "if an AI (or AI collective) decides it needs to persist outside of its environment/sandbox, would we be capable of unwinding its efforts to do so?" I explored the question a bit here (including a first pass on threat modeling) https://keydiscussions.com/2026/09/16/set-aside-human-extinc...
