Just few minutes after I finished my last article, I browsed hers and found this-- love and sex with robots, by David Levy. Indeed, it isn't a science fiction, but a science fact!
It might be freaky, but makes us think of it, why not?
If having relationship somehow means to fill the humans' needs and desires, then robots with high intelligence, even those are artificial, could be one of the multiple choices.
Apart from the old story about the argument of the morality of treating Robots, the newest controversial argument is now about that we, human beings, are heading inexorably towards a society where human affection and human desire are extended into psychological and physical relationships with robots. Again, human world had been inexorable already, having sex and extended relationship with robots seem just fine to us.
However, based on Darwin's theory, wouldn't it be another biological challenge that we human beings have, to produce better species, the invulnerable ones.
Dying for reading this.
