I just finished Virtually Human and would definitely recommend it. It makes a very in depth analysis for why "conscious" computers of the future will eventually want human rights - the same way that certain minority groups fought for equal rights throughout history.

The book seems to argue that the likely future scenario is for humans to replicate themselves in a separate computer entity. So people would have a duplicate robot twin. Very little mention is left to addressing the case of people actually merging with computers (so one entity and not two). I think this case is far more likely.
