If the repairman has a limited supply of spare parts then knowing how all the parts fit together (information) is not enough and its important to preserve as much function as possible. But I don't believe anybody is going to be revived (if they ever are) until full fledged Nanotechnology has arrived and in that case the parts in question are just atoms and the repairman has a unlimited supply of them, so all he needs is information. <br>

The egg has undergone turbulence and that means tiny changes in initial conditions have led to huge changes in outcome, we don't want that happening to brains. So the big question is, does the brain preservation method cause turbulence? I could very well be wrong because I'm no expert but my intuition says that plastic infusion is less likely to produce turbulence than freezing. <br>
