From a paper im writing

"

I recall a riddle heard in passing: if it were possible to do so, what would it mean to go to a doctor once a week and have a piece of your brain replaced with a synthetic functioning copy? If the procedure were done while you were conscious, and you repeated this process until no organic matter remained in your brain, when would you stop being you? The concept of the posthuman, an identity which transcends definition, a mind which transcends age, is a fundamental shift in our culture which technology is moving us towards at a rate we do not fully control. It is for this reason that we ought to at least be aware of its inevitability, so that the political will exists to make our reaction to these changes as reasoned as possible. "
