Artificial Intelligence is a great feat in technological advancement, but just like other advancement it's dangerous. Humans will always rule over these things because humans have the intellect of devicing new means of facing challenges when it comes unlike AI which is a programmed computer software intended for a particular task. Failure or fault in AI can Marr many things.
I've been reading some articles about artificial Intelligence and as what I've read AI is not that risky if implemented and created with cautions. Artificial Intelligence could probably break the glass from learning where do we came from or even how the universe started that is how intelligent it could be if we can design it properly. As of now, AIs do have limits and is weak for universal studies.
