I have zero faith in cryopreservation.
I have zero faith in "uploading consciousness".
So, if you upload your consciousness... is it really 'you' at that point? Or is it just an exact copy of you, and you are actually dead ? I've actually been pondering this recently, and I can't get past the continuity of consciousness during the upload process, to believe the end result would still be me.
Yeah, that's one of the big questions right?
I guess part of the problem is that we (or at least I) don't have a clear view of what makes up a person/individual. I mean, we know about brains being made out of neurons, glial cells etc., but have much more issues seeing how that translates to more abstract higher-order concepts such as consciousness, character etc. .
Perhaps the idea of an individual as a fixed entity is nonsensical. The 'you' of today is not the same as the 'you' of yesterday or that of 2 minutes ago. Phineas Gage before a rod through his skull was not the same person as Phineas Gage after the rod.
I still really don't get how go from a collaborating lump of cells to something like a consciousness, hope I will be able to grasp it one day.
