In the Walking Dead universe, the world fell apart in 2010. Based on how the series has been set so far, it would have a "culture shock" for Rick and Michonne by entering Greenwood, since it has been more than ten years since they have been exposed to conveniences of the modern world. Other than occasional use of the automobile or a helicopter, they have been living in the "Stone Age", without indoor running water or electricity. In 2010, Home Automation tech such as a robotic vacuum cleaner, digital conditional-access turnstiles, and voice activated smart home (climate-control, music selection and other digital assistant-features), were in its infancy.
Michonne runs into her friend Jocelyn, who takes away Judith and several other children in Scars (2019).
