I’m not sure that “killer robot” is the actual concern outside of media hyperbole. I’m imagining a loitering munition-type drone that has some kind of targeting package loaded into it with different parameters describing what it should seek and destroy. Instead of waiting for intelligence and using human command to put the munition on target, it hangs out and then engages when it’s certain enough that it’s found something valid.
In a world where LLMs produce very convincing but subtly wrong output, this makes me uncomfortable. I get that warfare without AI is in the past now, but war and rules of engagement and AI output etc etc etc all seem fuzzy enough that this is not yet a good call even if you agree with the end goals.
