What is "original"? And is the concept useful or important?

My point is that 'me', in the sense of the breathing person sitting here writing this to you, will undergo 'pain' and 'death' and cease to be. 'I' will no longer be able to experience life. There will be an electronic engram of the persona that developed inside this brainpan, but I, myself, will no longer be here, living life. Which is my point. Just because my silicon twin is out there, doesn't mean I get to get drunk and party.
