Hmm but we could program some laws like no hurting humans, or any other living being, that cannot be overridden ? Of course there will be always bad guys that will use AI for bad things, or their AI won't have trouble with living victims, but they will never have resources to power strong enoguh AI that can hack airlines, generate chatters and stuff like that. Doubt any nation or big company will be able to that in 50 years or even more.
Yeah, our weapons are really destructive now, but AI like that won't have mercy. If any nation fires nukes and nuclear war starts there is no way in practice all of the human race will wiped out, in theory yeah and then it doesn'matter who fired them, but that is only in theory.
