That is a good point. The love that children have for inanimate toys like dolls may be similar to the love for humans or animals. I too had these supports as a child. But by age 8 or so, the attraction fades away after realizing that the emotional support that objects give is insufficient. So I may be wrong about it being a completely intrinsic trait---maybe the ability to see a difference of these types of love is learned. But either way, Aibo doesn't seem marketed to children, as all of the videos feature adults using them. Maybe they are marketing to those who have or are willing to "unlearn" this distinction, so I think it will be a hard sell to people who have not considered this already, which seems rare.
