In his January 2010, essay “Killed by Bad Philosophy” Ken Hayworth discusses “mind uploading” from a philosophical perspective that includes a discussion of “what is the self” and a warning to not let current “scientific” philosophy lead to a “fatal” error in judgement about the possibility of “mind uploading”. http://www.brainpreservation.org/documents/killed_by_bad_philosophy.pdf . I found his essay to be a fairly comprehensive look at several aspects of mind uploading. On the subject of what makes you “u”, he recognizes that the “self” is constantly evolving and being developed by the moment to moment experiences and memories we build everyday and is different from our “sense of being present” .e.g POV self. At LifeNaut.com we encourage interested people to get started early building a “mind-file”, so as to capture as many ‘Bemes’ (memories,attitudes,values, beliefs and mannerisms) to be ahead of the curve, when AI software called ” mind-ware” can one day use that information to transfer your “unique’ information / consciousness to new forms eg. robots, computers, bodies.
