Context seems to be here.

I'm also willing to put, let's say, $100 on the line at 5:1 odds that this isn't going to get a Hugo for Best Novel. (Best Fan Writer is far more feasible, though I'd still give it less than even odds if there's a push for it, and less than that if there isn't.) Reasoning: it's an atypical work for the category, which already steeply discounts it; it doesn't display any particular literary fireworks or great innovations in terms of setting or speculative fiction conventions, which is what the Hugos have tended to look for (historically more the later; lately more the former); and it doesn't have any particular following in, or ties to, literary SF fandom as far as I'm aware.

You could argue its significance for the fanfic form but that's going to be a tough sell to Worldcon.

(My actual probability estimate is more along the lines of 50:1 or lower, but I'm not prepared to go through that kind of trouble to win a couple of bucks, nor to risk thousands of dollars on the off-chance that someone knows something I don't.)

I assume he means: we are not in a position to have any confidence that a particular proposed magical solution is actually a credible one, at least from what we know that's internal to the story. (External things like what's been most clearly foreshadowed might give good reason for confidence.)

I really can't believe "use magic" was the right answer. In addition to being unsolvable from the perspective of the audience -- we don't know anything about magic! -- it's also totally out of step of the rest of the work. I'd love to see a rewrite fork from the "AI Box" line of solutions.

In the meantime I really hope they're still in the mirror.

I wrote a version of this up at reddit too, but it seems to me trying to hack the laws of physics is wasted effort when we know very little about how magic works in concrete terms. We don't know what Harry can really do, how fast he can do it, or whether Voldemort would notice.

What we do know are: * how Harry thinks * how Eliezer thinks * what Voldemort wants

So we should be looking at things Harry could say that would advance his goal of surviving rather than trying to come up with a combination of spells, with the understanding that winning ideas are probably going to cluster around narrative interventions that EY thinks are interesting or important. A few that spring to mind:

Memetic hazard: are there things Harry could say or bring to Voledmort's attention that would pose an existential risk to him if he harms Harry

Let the AI out of the box: is there something Harry can offer Voldemort such that Voldemort goes against his stated agenda

Precommitment / timeless decision theory: are there ways Harry can manipulate the unbreakable vow to force certain conditions in the future

Learning to lose: what if Harry surrenders and agrees to join Voldemort, with a commitment Voldemort finds convincing

Unintended consequences: Harry makes a convincing case that there is no way to outthink an inevitability other than to fulfill it in terms that are advantageous to you.

I really think didactic lessons about rationality are going to be better, and more appealing to EY's sensibilities, than trying to fanwank some way to use magic to kill 38 people in a single play. We just don't have the rulebook for that.
