It's funny that in most SF, they consider the brain the only things to copy to be a person. But given we have neurons in the heart and guts, that the chemicals we have it our body and the digestive activity affect our behavior and that discover everyday that a lot of "us" is actually made up of alien micro-organism taking a role in almost every parts of our daily lifes, including hormones management - a crucial piece of our reaction puzzles - I think it's far from realistic. I can't wait to see the first people uploading their brain in a machine, only to discover that: - A, it's just a copy, not them; - B, the copy is not nearly close to the original; - C, they feel that they are missing something but they can't express it because the missing thing helped them defining it. I swear, we geeks love to solve perfect problems with perfect solutions. Like the joke of the physicist that can cure a chicken, but only if the chicken is a perfect sphere in a frictionless vacuum.
