In a perfect world, AI makes sense to protect you and your family. People pay a lot for protection whether it is a bodyguard, home security, trained dog that needs constant upkeep) weapons. All of this could be conveniently replaced. BUT would I?? Hell no, there is something very wrong with something so vicious with no conscience or reasoning other than a computer chip. It would just be like the blockchain...it can't be hacked but any platform on the blockchain can be hacked. So, I would have to think that an AI could be hacked and turned against you.
