I think we could eventually "Ship of Theseus" our brains to hardware and eventually software (thinking protein-based "walkers" along neurons that copy nodes and IO strengths to build a graphene/nanotube-based memristor network with interfaces for current connections to existing neurons as well as interfaces for eventual software conversion), which would thus maintain continuity of consciousness and I'd feel better about it actually being me instead of "just a copy".
Really I just want to get to the point where I can remotely control either a physical or digital avatar at will, without having to worry about my existence ending. Bonus feature: I might be able to extend myself to control two or more avatars simultaneously, or be able to communicate with similar minds in a much faster manner, creating a much faster, more comprehensive form of intelligence.
