After a researcher with a position at DeepMind—the machine intelligence firm owned by Google parent Alphabet—co-authored a paper claiming that AI could feasibly wipe out humanity one day, DeepMind is distancing itself from the work. 

The paper was published recently in the peer-reviewed AI Magazine, and was co-authored by researchers at Oxford University and by Marcus Hutter, an AI researcher who works at DeepMind. The first line of Hutter's website states the following: "I am Senior Researcher at Google DeepMind in London, and Honorary Professor in the Research School of Computer Science (RSCS) at the Australian National University (ANU) in Canberra." The paper, which currently lists his affiliation to DeepMind and ANU, runs through some thought experiments about humanity's future with a superintelligent AI that operates using similar schemes to today's machine learning programs, such as reward-seeking. It concluded that this scenario could erupt into a zero-sum game between humans and AI that would be "fatal" if humanity loses out.
