The biggest plus point of sexual reproduction is that it is intimately tied up with natural selection. If environmental conditions change sverely then many genetic combination will be eliminated by natural selction. While new combinations that can survive the environmental shock will gain advantage and proliferate. This is possible only if genes can be mixed around, as in sexual reproduction. Cloning is a dead end as far as natural selection is concerned. And the "technology" for sexual-reproduction is extremely widespread, simpler and cheaper compared to cloning anyday. <!--emo&

[P.S. Hauma, cloning is "cheaper" for nature as compared to sexual reproduction. But as far as humans are concerned, sexual-reproduction will always be much cheaper to cloning. ]
But in case such environmental shocks are not imminent, and humans have perfected the technology to clone, then cloning will happen. May be the husband loves his wife so much that he wants someone "like" her to survive even after her. So they decide to get a daughter cloned after the mother. I can imagine similar "emotional" reasons. People who depend strongly on physical appearance and physical prowess for success, such as movie stars and athletes, may be especially tempted to try cloning.
I am sure there will be some kind of genetic copyright legislation, that gives an individual all rights on his/her genetic material. One possible use/abuse could be that geneticall well endowed people "selling" their cells for cloning purposes. But is that that much different from the present society where rich people often manage to effectively "buy" genetically well endowed partners for sexual reproduction.
Future Japanese Robots will surely perform many roles, such as assistant, maid, spouse ... One kind of zombies the future society will have to deal with will be the people that stay completely separated from other humans, living in their own virtual world with internet and robots for company.
Robots obviously have a sensory system, an observation & analysis apparatus, and a motor system. So they do possess, senses, mind and action organs. As far as sAMkhya is concerned, manas, buddhi, ahamkara, j~Nana and karma indriyas are all material. So no conflict there. But will a robot ever have a "purusha", the witness consciousness? I think not in the near future. But I think in far enough future it may become possible. If "consciousness" is as immanent as we see scattered around in all sorts of life forms, then I don't see why it can't get manifested ina robot too. Science will have to gain a thorough understanding of consciousness for this to happen. Current understanding is very limited, but I don't think there is an upper bound.
So, I think robots can eventually have "consciousness". But is that identical to having a "soul" or jIva? I don't think so.
A "soul" is about what survives even after the death of thephysical body. A "consciousness" is a about present tense. An entity that is aware of its surroundings and responds as a single cohesive entity can be called conscious. Many species are believed to be conscious but supposedly don't have "souls" in the sense that nothing like a jIva survives after the death.
As far as I am concerned,an electron is conscious too. It senses (or observes) electro-magnetic , weak and graviatational forces and responds as a single entity. But a collection of electrons is normally not 'conscious' as a single entity. Although collective quantum phenomena exist such as superconductivity where, a collection of electron-pairs start behaving as "one" entity. In many situations, a collection of humans starts showing a distinct and cohesive personality too. In such situations I would call the collective entity conscious too. Japanese have to just manage to get the their robot's silicon neurons to learn to behave in some collective phenomena a-la Quantum mechanics. May be then the robot as a whole could be considered conscious.
In hinduism, jIva is intimately tied up with concept of karma and karma-phala, reincarnation etc. That is a big organizational machinery supposedly run by the ethics committes of the Lord(s) of Karma (karma-phaleSHu-juSHTAm ). <!--emo&
