>But if you followed the physics and anti-Zombie sequences, it should now seem a lot more plausible, that whatever preserves the pattern of synapses, preserves as much of "you" as is preserved from one night's sleep to morning's waking.

Part of the problem here, though, is we don't even have proof-of-concept. We know the freezing process damages the brain, or else we'd already be able to revive people, no problem. Being complicated, the brain tends to get complicated in damaged ways. In spite of our best efforts to provide effective treatments for stroke victims, we don't even understand all the causes of neuronal death in strokes. Almost certainly, freezing and thawing a brain damages it ways we don't understand yet--maybe subtle ways, throwing of biochemical processes in ways that are hard to fix. Is there any reason to think we will ever learn to deal with all of the relevant problems?
