And it would immediately not be you. A chip would have no way of gaining the new information that you would be gaining. The scan is over and you look at the chip and say "wow." Right there, an experience the chip doesn't have. You conclude the chip doesn't have that experience. There's another experience the chip doesn't have. It goes on and on. Not to mention the fact that the chip cannot actually do anything by itself. Frankly, I cannot believe I'm typing this. The whole concept is absurd.
No more absurd than having twins.
The almost meta-physical philosophy of it IS pointless, however.
Granting the hypothetical technology to do it... The scanned person and the copied person would both be the same exact person immediately. After that, they would become less and less like eachother, but they would also remain remarkably similar in basic traits for a very, very long time. Even with different experiences and such, the copy and the scanned would remain essentially the same person for quite a while, Reacting to things in the same way, making similar decisions, having the basic same temperment and so on.
To put it more simply: My grandmother barely changed at ALL in 40 years, in spite of 40 years of experience.
If I was scanned and a copy made, it would not bother me In the LEAST to know that he was a duplicate- that he was basically the same person as me. I might try to give him advise about his behavior, knowing all the while that he/I won't listen...
He might marry some woman whom I would wonder why he picked, nevermind the fact that I might have picked her too if the circumstances were right.. Moving along to bear their little duplicate robot children whom I would not love as I do my own, even though they have the "same" father...
I really think, from what I have read in this thread, that the OP wanted to stay the heck AWAY from the Meta-physical philosophy.
The thread struck me as a "Benefits or liabilities of Immortality" discussion rather than a "Is a copy of me still me" discussion.
Changing the premise-
Imagine that you found the Fountain of Youth- Would it be cool to live forever? A strain on your psyche? Incredibly boring?
