Surrogate robots?

So I just saw the new movie, “Surrogates” and all I have to say is that I hope we do not live our lives like that in the future. For those of you that have not seen it, basically the plot is that we live our idealistic lives through surrogates (basically robots). Our minds control their actions and we can take on an identity that we see as our supreme way of being. It is just mind blowing to see that this could be a possibility someday, especially with all the technological advances made as of now.
Personally, I feel that it is a wrong concept that through robots we are able to take on different identities. Were we not made to be unique on our own ways? Like I know there are things about me that I would love to change, but that doesn’t mean if I could that I would. I like feeling real things, like sand between my feet, and experiencing feelings of joy. Not all the time I enjoy feeling certain emotions, but that is what we as humans are supposed to be like. I'm not saying that human as a species have a protocol on how each and every person should live their lives. But don’t you agree?
So my thoughts are, what are the pros and cons if we did live through robots? Depending on the person there are probably mixed reviews. Here I think there are more cons than pros so I made a list:
1) What if we used robots in wars, would wars ever end?
2) If people take on other identities are they rejecting a gift the creator gave to them ?
3) How could we know the difference between if someone is truly who their robot shows? (An example in the movie was that a 40 year old man had a robot to represent himself as a 20 year old female)
4) Would we be able to reproduce? If we live through our robots, how will we continue humanity?
5) How will our future generation learn true emotions or events? How will they attain real memories, and not the actions they felt their robot take part of. For them it will be like looking through a telescope and seeing something that you can never feel.

I have to say, go see this movie and it truly will have an impact on you. If you liked the movie wall-e, this is something you will also enjoy, because it truly makes one think, what if we lived our lives through surrogates?
