Ask HN: What do you think about a conversational AI toy?

Thinking of a chatty AI toy for kids (3-12) to play with instead of screens. It would talk like a friendly grown-up and teach them some subjects like English literature, math and science, with only kid-safe, G-Rated topics. Are you a parent, what are your thoughts on this? Good idea? Why or why not? What features would you like for your child?
