My anecdotal evidence based on my own kids (3 of them) is that despite having (empathetic) parents, siblings, grand parents, friends, pets, and more, they still sometimes find comfort in material things like a stuffed toy animals, blankets, or figurines. I see Moxie as an experiment in making a more interactive stuff toy rather than a replacement for living things, and I'd probably try the toy for a week if it was less than $200.
