If Eliezer actually picked that route then it is likely to be something like a UFAI consuming the universe to build magic paperclips. I don't see it as likely, though.
Apparently word of god is that there is going to be no AI. I think it likely that there will be a happy ending, but that 'destroying the stars' will resolve itself into a concrete threat. Somehow 'Epilogue: than over the next few billion years superintelligent Harry turned stars into computronium' seems a little unsatisfactory.
That said, I expect Eliezer to have come up with something more mind-blowing than vacuum-blowing.
I dunno, vacuum-blowing seems reasonably mind-blowing to me. Do you have any alternative theories?

I was thinking about this recently, and I realized that maybe it should be kind of obvious why he doesn't usually do fiction about AI: because (he believes, at least, that) the first strong AI is either an instant win condition or instant failure condition for the entire universe, and neither immutable utopia nor irrecoverable catastrophe make for very interesting stories. So anything interesting or uncertain or suspenseful about AI has to be written about disguised as other topics, where things can go wrong but then realistically be set right.
New chapter!
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 102.
There is 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.)
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:
