How will we face being defeated by machines?

What can we learn from losing? That's the question at the heart of the documentary AlphaGo, about an AI program designed to play the ancient Chinese board game Go. The film follows AlphaGo and its creators, the Google-owned firm DeepMind, as the program defeats first the European champion, Fan Hui, then the legendary player Lee Se-dol. Fan and Lee are forced to answer this question as they're overwhelmed by AlphaGo's uncanny play style. And as artificial intelligence imitates more of the qualities we consider uniquely human, their conundrum is an important preview for the rest of us, who may soon be asking ourselves the very same things: What will do when a computer takes our jobs?
