In the past seven months or so, we as a society have spent a lot more time at home. Some of us in the company of family, maybe some pets or maybe with some robots. Our computers, smartphones, smart devices and even Roombas are taking on new significance in our lives as we are forced to stay away from other people. These robots, and our relationships with them, are the subject of a new audiobook by Ayanna Howard, a roboticist at Georgia Tech. The book is called “Sex, Race, and Robots: How to Be Human in the Age of AI.” Amy Scott speaks with Howard about the danger of gendered digital assistants.
