I feel the real AI threat is not so much robots, but automated computerized decisions. Like eventually they may replace government services with AI. Then people may be denied things like passports etc because of something you did or said online that was badly interpretted by the AI. Kinda like how youtube often demonetizes videos because it thinks someone sweared but it's a word that just sounds like a swear. Imagine that kind of AI taking over every day life things. And you will have nobody to complain or try to get help from because it will just be all automated.
Automated law enforcement would be another big threat. Based on your purchases, or places you've been it might think you're a terrorist and then you get arrested. The cops would have no say because they just follow what the AI told them to do, and you would have no access to a lawyer because the AI is always right and you don't need a lawyer. I could see stuff like that happen in the near future. Basically every aspect of our lives will be ruled by a central AI. Though I could also see that only happen near the tribulation and the mark of the beast etc would play a role in all of that.
