Oh....I'm going to watch that. Sounds like scifi, which is one of my most favorite genres.....
How can a robot have sex?
What's the purpose of creating a robot that can have sex?
...Actually, don't answer that question.
What's the purpose of creating a robot that can have sex?
Why do you think the idea of humanoid robots came into existence anyway? Creating near-human-like robots that can have sex with humans is like the ultimate goal in the field of robotics. And after that has been accomplished there will no longer be a field of robotics or any other field, because nobody will ever do anything again because they prefer having sex with their robot. It'd be like in that Futurama episode.
I think you're confusing the ultimate goal of robotics with the ultimate goal of sex toy manufacturers.
Why not kill them?
