In short, I think that with advanced enough A.I. (but not too advanced, per the above) sex or companion robots could very well become the ideal mates for humans. Human-robot relationships could be purely sexual, or they could become more like true companions. Either way, such human-robot interactions do not necessarily mean the end of human-human interactions, or inevitable extinction for lack of reproduction. There are, after all, plenty of children to adopt, and there is little reason to think that the technology involved in creating children will fail to advance as rapidly as other technologies.
