# Joanna Stern Documents Yearlong AI Experiment and Parenting Lessons > Source: > Published: 2026-06-29 13:32:41+00:00 For practitioners: consider how prolonged, multimodal AI use surfaces interaction design, trust, and data-quality problems that matter when AIs touch family life. Business reporting shows journalist **Joanna Stern** spent a year integrating AI into home and work activities and chronicled the experiment in a book, reported by The Guardian and Business Insider. Business Insider, Forward, The Guardian and 247wallst describe Stern testing chatbots, humanoid and home robots, `Claude`, `Gemini`, self-driving cars, a cooking robot (Posha) and a robot dog (Sirius). 247wallst reports Stern found administrative offloading to be the clearest productivity win, while Business Insider's essay-style piece highlights that the experiment reinforced the primacy of human relationships and that children need "real-world training data," per Stern. Reporting also notes provocative experiments such as an AI companion role and AI-assisted medical parsing, documented across The Guardian, Forward and 247wallst.
