Should you be worried about progress in Artificial Intelligence? Will Artificial Intelligence destroy jobs? Should we fear killer robots? Does Artificial Intelligence threaten our very existence? Artificial Intelligence (AI) is in the zeitgeist. Billions of dollars are being poured into the field, and spectacular advances are being announced regularly. Not surprisingly, many people are starting to worry where this will all end. The Chief Economist of the Bank of England predicted that Artificial Intelligence will destroy 50% of existing jobs. Thousands of Artificial Intelligence researchers signed an Open Letter predicting that Artificial Intelligence could transform warfare and lead to an arms race of "killer robots". And Stephen Hawking, Elon Musk and others have predicted that Artificial Intelligence could end humanity itself. What should you make of all these predictions? Should you worry? Are you worrying about the right things? And what should we do now to ensure a safe and prosperous future for all? Toby Walsh is a leading researcher in Artificial Intelligence.
