I asked Koklys to start describing Eno’s character and how it might emerge during a conversation. Eno, for example, would never be funny or cute when it failed to understand. It would use humor only to show empathy with someone. “Eno has core traits, a backstory, and things Eno likes and dislikes,” she said. “We actually designed character flaws because we found that’s how people connect with characters.” I asked what that meant: What was Eno’s personality, and what were her personality flaws?
