So far the other comments are (for some bizarre reason) pretending robots can actually mimic the experience of companionship by another human. That is simply untrue. There's an untold number of factors that influence hormone releases constituting social bonding, and robots meet none of the necessary qualifications. So far, other commenters have simply been using this post as a vehicle for their detestable ageism and sexism (no better than racism and homophobia, both of which I experience on a near-daily basis [sexism too, but not ageism all the time]), and that's not only abusive to human beings but it's entirely unscientific in nature.
