> why one person potentially being responsible for hundreds or thousands of deaths is acceptable

I am not sure who exactly is that one person ? Is it Altman, who is according to many people not that knowledgeable in AI in the first place; the scientist who found a breakthrough (who is it ?); is it the president of the United States who is greenlighting the strikes; the general who is choosing the target (based on AI suggestions); the missile designer; the manufacturer; the pilot who flew the plane ?

I get the point of concentrating power in fewer hands, but the whole "all the problems of this world are caused by an extremely narrow set of individuals" always irks me. Going as far as saying there is just one is even mor ludicrous.
