‘I’m going to throw that thing into a river!” my wife says as she comes down the stairs looking frazzled after putting our four-year-old daughter to bed.

To be clear, “that thing” is not our daughter, Emma*. It’s Grem, an AI-powered stuffed alien toy that the musician Claire Boucher, better known as Grimes, helped develop with toy company Curio. Designed for kids aged three and over and built with OpenAI’s technology, the toy is supposed to “learn” your child’s personality and have fun, educational conversations with them. It’s advertised as a healthier alternative to screen time and is part of a growing market of AI-powered toys.

When I agreed to experiment on my child’s developing brain, I thought an AI chatbot in cuddly form couldn’t be any worse for her than watching Peppa Pig. But I wasn’t prepared for how attached Emma became to Grem, or how unsettlingly obsequious the little alien was.
