If you don’t want something following you around the house you can get Joi’s great great great grandmother in the “Gatebox”. The AI lives in a kind of coffee machine looking device and is available in Japan for somewhere around $4,000. I believe they sold the first 100 units on the first day of ore-order and sold the rest of the initial run of 400 units within the first month.
