That sounds dangerous to me. Not like I think you did something wrong or exposed your daughter to danger at all; it was probably a really useful exercise. The scary part to me is how readily she accepted it as human, or friendly.

We already know how well people are deceived by text and images. Imagine if they're getting phone or video calls from "people" who keep them company for hours at a time. Imagine if they're accustomed to it from an early age. The notion of dealing with a real, messy, rough on the edges, honest human being well become an intractable frustration.
