It depends of if you consider a copy of your mind to be "you" in any real sense. If there was an exact copy of me right now, I would not consider that copy "me" - rather it would be a duplicate person, but not me. There could be 10,000 identical duplicates of my brain out there and not one of them would be me. That being said I doubt that freezing has any chance at all of actually being able to revive someone to their previous mental state...

Technically you are not the same person as the 5 year old you. Every cell has been replaced.

It would only be a facsimile of you at a specific moment in time... which would make each facsimile on parallel paths... scary

Yes, for the Catholics who believe storage kills your soul.

Oh come on, chances of either of those ideas working within the next 1,000 years are effectively zero.

We get 80 years if we are lucky, and we waste so many of them, that wondering if we could get a magic save point is foolish.

Take those valuable brain cycles and work on fixing code used by cancer research charities

Slicing up a brain and scanning it with a microscope is something we can do fairly well now. Given that the EU just put a billion euros towards a brain modeling project, I'd say the odds aren't so bad. I'd bet on it happening by the end of the century.

No. Here's a billionaire's ambitious and "plausible" plan on transfering his brain into a model and using a holographic body rather than a physical one. http://www.youtube.com/watch?v=01hbkh4hXEk
