Google recently built an AI that can learn how to play a Atari video game itself, after a while of training, it can master the game. The most impressive part might be that the AI not only matched wits with human players in most cases, but actually went above and beyond the best scores of expert meat-based players in 29 of the 49 games it learned, and bested existing computer based players in a whopping 43.
This experiment really aware me, although AI is still in the beginning part, it can already beat human being. AI play a game just a prototype, it will be used in military, in transportation, in medical, in every parts in our life. If it goes good direction, maybe it can give more accuracy surgery than a human doctor, or it becomes a trusted friend and entertain us during tedious works. However, if AI weapons is created for conquer and war, then it will destroy human, and finally it will becomes the war of AIs, maybe the scenario in science fiction movies will come true.
But we can’t stop the development of AI, we need the growing technology. Besides, at meantime we focus on the innovation of technology, we also need take a glare at ethics, before publish the technology, be aware of the influences.
