Artificial intelligence could be devastatingly dangerous

Artificial intelligence is quickly advancing. In 1964 the first major AI, ELIZA, was built, and it could only hold a conversation from a script. Now, AIs like Apple's Siri, Windows' Cortana and Amazon's Alexa can interpret human dialogue to an amazing degree, and fulfill commands. It is benign now, but AI is something with which society needs to be cautious. AI has the possibility of creating a human society so advanced we cannot even imagine it, but it also has the capability of upheaving our societal system and upheaving us with it.
