Cloning in general can be a good thing when it comes to food or things used for medical purposes. I don't even see it as that bad in animals and humans (if it works correctly of course.) They can never be slaves though. They aren't mindless zombies fit to do anything and everything. They would be human beings just like me and you. I don't even think a clone would be the same person passed the genetics. I think the person's brain would develop differently and could be considered an entirely different person. I guess that is still to be seen, at least publically.

cloning would be amazing, but there are smaller problems like restaurants, sweet shops etc going out of buisness, microsoft, sony, people could clone their consoles, putting them out of buisness
