I do not see how that would follow at all, could you please explain?
Reversing information-theoretic death is fundamentally the problem of taking a bunch of atoms in random configurations and getting a person out of it - and not just any person, a particular person about whom you no longer have any data whatsoever.
This problem is fundamentally equivalent to time travel: if you can time travel, you can just go back and copy the original, and if you can reverse information-theoretic death, you can "resurrect" the visible universe at whatever time and put yourself in, essentially, a simulation of a prior time.
Dumbledore has already told Harry that he tried a variant of this once and that it didn't work. "Time" didn't like that. See this quote from chapter 90:
Actually, there's a stronger example from the Standford Prison Experiment arc, which is why I already retracted this point. (Though why it doesn't work is still a legitimate and interesting question.)
This problem is fundamentally equivalent to time travel
I agree that if you solve time travel you can also solve death, but the other implication does not hold. A possible way for Harry to "resurrect" Hermione is to scan her brain, run it through an error-correcting algorithm (to reduce/remove errors introduced from decay and it being transfigured) and then "print out" a brain that is arbitrarily similar to Hermione's brain at the moment of her death. This will of course depend on the amount of computing power available to Harry, but ...
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapters 91 & 92 . The previous thread has passed 500 comments.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,18,19,20.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
