I don't think people are afraid of skynet level AI taking over the world. Current AI is more likely to cause people lose their jobs to vastly inferior but cheaper AI bots. Executives are overestimating its value over real humans, and with right marketing you can easily convince them to fire people in favour of bots. Its a threat of automation where only people who profit are top 0.01%. While nukes might end the world, I don't think we should ignore any other threat just because nukes exist. We shouldn't mindlessly add more tech in our lives where none is required.
