Should we be worried about Artificial Intelligence (AI)? On the one hand, there are big names that have expressed major concern. Elon Musk, Bill Gates and Stephen Hawking have all argued that AI poses the single biggest threat to mankind's existence. At the same time there are people such as Mark Zuckerberg (Facebook CEO) and leading AI researcher Andrew Ng, who reject this view as scaremongering, and insist that the risks behind AI can be eliminated by following a few simple rules. Clearly they cannot both be right, meaning that the truth must lie somewhere in the middle: AI cannot be without risks, but nor can it be the apocalyptic threat some say it is.
