Who has responsibility when AI is running the show?

With accelerating advances in artificial intelligence, the world of AI is weaving itself -- almost imperceptibly at times -- into the fabric of our lives, affecting how we move and live and relate. But as AI extends human agency, intelligence and action in the world -- sometimes replacing human beings entirely for certain tasks -- it raises increasingly complex issues of ethics and responsibility. Paula Boddington, senior researcher at Oxford University's Department of Computer Science, tackled the subject head on, addressing a packed audience at the Mobile World Congress in Barcelona last month. For a topic that presents many more questions than answers, she offered a glimpse into how technology brushes up against philosophy. "The power of AI is pushing us towards questions about the very limits and grounds of our human values," Boddington says.
