Disagree with this. Kids are sponges who pick up on many secondary factors when an actual human gives them an answer. These factors add significant weight to their view of the response. In many cases, this actually reaches an extreme where what is said end up being tertiary to how it was said and who said it. I am sure you've experienced this even as a an adult.

An AI walkman removes this aspect of the interaction. As a parent, this is not something I would want my children to use regularly.
