Interesting video. The one thing that strikes me about each scene is how much of an uncanny valley being around one of those things would be. That would be the first step---to get used to that. Then you'd have to bring yourself so low to actually associate the human feeling of love with a physical unliving object. I don't think there's any way to do this to any degree unless you force yourself to develop a borderline mental disorder over time or believe in animism or something similar. It's not just how you're brought up---the ability to distinguish living things from objects is inherent from birth at a fundamental level, which is why I think the "dog replacement" and attraction claims in the marketing is nothing but silly.
Silly to you. I wouldn't want one of these either, but that doesn't mean I can't empathize with somebody enough to understand how they could find enjoyment or feel affection towards one. Did you ever have or know a friend with teddy bear? Even as a child you know it is not real, but that doesn't mean you can't be attached or even pretend that it loved you back.
