I also find it unlikely Harry hadn't heard of cryonics. I mean, I'm born in 1981 almost like Harry, and when I was Harry's age, I definitely had heard of it, like I had heard of robots, or long-distance space travel, or life expansion, or robotic prosthesis, as a scifi device. I had seen 2001 and Star Wars. And I did think at that time "oh, it's something cool we'll have in the future". Sure, I didn't know it was something actually existing in the real world. But while I wasn't a dumb kid, I wasn't the supergenius Harry is, and I didn't even think defeating death was something possible.
So, yes, I would say it's unlikely for Harry not knowing about cryonics. But... not "1 chance in 1000" unlikely, more like "1 chance in 10" unlikely. And if you have 10 "one chance in ten unlikely" things, well, statistically one will actually happen. And it's fully within the author's "rights" to say "well, among those ten things there is only one chance in 10 Harry doesn't know about, it's cryonics he doesn't know about".
So while it's unlikely that Harry didn't hear about cryonics, it's not unlikely enough to really sound artificial. Harry knows a lot, not all, and cryonics is where he fails, ok, fine.
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 chapter 98. The previous thread is at nearly 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.
