Can artificial intelligence be trusted - and is it too late to ask?

Artificial intelligence (AI) that can tell pre-cancerous growths from harmless moles is great. AI that can clone human voices to counterfeit utterly convincing recordings, seeding doubt and misinformation is not so great. As a technology, AI is unprecedented, powerful and deeply pervasive: from voice recognition to self-driving cars to medical diagnosis, it is swiftly weaving its way into our lives at work, home, and everywhere in between. Yet most of us know very little about it. It's easy to say that fear of the unknown is fruitless, but how can we understand and leverage AI to create the best possible society without succumbing to fear, doomsaying, or prophecies of a fate worse than war?
