What about a Neuromancer style brain upload where a computer takes a series of very long incredibly detailed interviews and brain analysis and constructs a simulation of that person? Sure it might not be exact but, as you said, it really can't be you unless it's the whole thing anyway. At least this could create a computer that would react like a specific human most of the time and I don't think that something of that level of sophistication is really that far away (as in <50 years at current progress).
