What does it mean to have an identity? What does it mean to be you?
"Let’s say you transfer your mind into a computer—not all at once but gradually, having electrodes inserted into your brain and then wirelessly outsourcing your faculties. Someone reroutes your vision through cameras. Some one stores your memories on a net of microprocessors. Step by step your metamorphosis continues until at last the transfer is complete. As engineers get to work boosting the performance of your electronic mind so you can now think as a god, a nurse heaves your fleshy brain into a bag of medical waste. As you—for now let’s just call it “you”—start a new chapter of existence exclusively within a machine, an existence that will last as long as there are server farms and hard-disk space and the solar power to run them, are “you” still actually you?"
I contend that I would not be me. Let's say we took what is irreducibly me (all the atoms, quantum particles) and replicated it perfectly, forming what is otherwise an identical clone, indistinguishable scientifically from the original copy. I find it hard to believe that there are two of me. There is "me" (the original copy) and there is "me" (clone). My conscious experience is integral to the matter from which it is derived, although at the same time matter is being turned over moment by moment within my own brain, so am I contending that I am a different person millisecond to millisecond? I think my brain is frying.
