hello @joseph1956,
I personally believe that the real danger is when artificial intelligence is combined with robotics, that is where they can represent a real danger just imagine a robot that can think and make their own decisions if you add to that that developed countries will surely give weapons is very likely to get out of control and end up hurting more than one person, for now do not represent a problem but only the future will tell if it was foolish to create an artificial intelligence or on the contrary it was a good decision.
