Inside Amazon's $3.5 million competition to make Alexa chat like a human

Onstage at the launch of Amazon's Alexa Prize, a multimillion-dollar competition to build AI that can chat like a human, the winners of last year's challenge delivered a friendly warning to 2018's hopefuls: your bot will mess up, it will say something offensive, and it will be taken offline. Elizabeth Clark, a member of last year's champion Sounding Board team from the University of Washington, was onstage with her fellow researchers to share what they'd learned from their experience. What stuck out, she said, were the bloopers. "One thing that came up a lot around the holidays was that a lot of people wanted to talk to our bot about Santa," said Clark. "Unfortunately, the content we had about Santa Claus looked like this: 'You know what I realized the other day? Santa Claus is the most elaborate lie ever told.'" The bot chose this line because it had been taught using jokes from Reddit, explained Clark, and while it might be diverting for adults, "as you can imagine, a lot of people who want to talk about Santa Claus … are children." And telling someone's curious three-year-old that Santa is a lie, right before Christmas? That's a conversational faux pas, even if you are just a dumb AI.
