Just remembered a serious objection, originally from Tarhish on reddit:
I had been thinking about this possibility for a while, but now it also requires Dumbledore to have lied about Lily and James hearing the prophecy in the Hall of Prophecy. Because if they did, then it means they were mentioned in the prophecy, and this theory does not, at first thought, seem to allow that.
(from here, it's only 4 months old, you still can upvote that)
This argument can be somewhat handwaved away by "James is ascendant of Ignotus Peverell, and prophecy talks about several possible futures", but still.
In canon, the assignment of eligible hearers to prophecies is done by Minesty workers. Specifically, the judgment that "the one with the power to vanquish the Dark Lord" refers to Harry, and thus that Harry should have access to the prophecy, was made some time after the recording of the prophecy, by a human. On the assumption that things work the same in the rational-verse, the fact that Lily and James could hear the prophecy isn't evidence of anything other than the interpretation of the Minestry worker who handled the case.
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 96. The previous thread is at almost 300 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, 21, 22, 23, 24, .
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:
