Google, Facebook, Microsoft, and Slack Designers Explain the Art of Creating Smart A.I. Bots

Siri--and all her artificially intelligent peers--are increasingly taking on more tasks for people at home and at work. But as impressive as these digital assistants can be, they're still very much in their infancy. "I don't think anyone has nailed the user experience yet," warns Jason Cornwell, who leads the team at Google tasked with designing exactly that. Still, the biggest players in artificial intelligence (A.I.) agree on some important design lessons. Cornwell shared a stage with execs from Slack, Facebook, and Microsoft on Thursday at Fast Company's Innovation Festival in New York City.
