The robotics revolution is coming. This revolution will include intimate relationships between humans and robots. When should we expect this to happen? Sooner than you think.
I feel like myself and others will/are having the same opinion towards people and robots as older people view same sex couples. It'll be interesting to see how people view these developments in 20 years and whether younger generations resent the older generations "robophobia". I could be making this up but it does prove our generational desires for progress only go so far.
I think you bring up a great point re: societal perceptions of human-robot sex in the 2020s-2030s. Younger generations will definitely be more accepting, however there will be a large cohort within our generation that are also accepting. I know I wouldn't care. Our generation is one of the most accepting and tolerant to ever live. Also one of the most educated. So there may not be an overwhelming amount of resistance to it.
"Cum with me if you want to live!". TM 2013 humanodon industries inc. On a less jocular note, given the state of robotic prosthesis, how far are scientists from recreating natural human movement? It seems like they're a long way off from being able to produce natural motion in a robotic limb, much less a robotic body. Sure, there are those that will settle for far less than a close approximation of sex, but I doubt many would be eager to be reminded that they're congressing with an automoton during the deed.
Well I feel this video (released this year) demonstrates that researchers are making considerable progress on recreating natural human movement. Of course, it will be a gradual development. The first "sex robots" or robots that we have sex with will not be "as human-like" as the robots we have sex with in the 2030s.
