Worse, still, unless the current me blinks out of existence, "old me" will still be around - unless we can replace neurons in-place with computational analogs, the original me is destined to die, almost no matter what, even if a copy/download is made. From the download's perspective, it continues, but the original, if not ended then and there, still faces a grim end and will know it.
