On the other hand, if there was a way to "digitalize" a brain and let it run in a simulation, it could still be conscious and have the same possibilities as the brain of a normal person with a normal body, but it would still be a duplicate of it. I don't think it's ever going to be possible to "transfer" yourself to a copy without dying. Sentience is far too intertwined with the physical aspect of the brain for it to be possible to transfer yourself into a copy without dying.
