With regards to (2), I think you’re confusing first-year war games with actual combat magic.
Actual “I really want to kill you” spells are probably much more powerful. Fiendfyre for example has at least the destructive potential of a tank, and in canon even Goyle could cast it. (It’s hard to control, but then again so is a tank.) Avada Kedavra can probably kill you even through a nuclear bunker wall, and it can be used by at least some teenagers. Sectumsempra is probably a instant-kill against a muggle, even with body armor, and it was invented by Snape while he was still a student.
By contrast, pretty much the most powerful potential weapon normal people (well, outside the US at least) have ready access to is a car, and a very tiny fraction of people can easily make something much more destructive than a crude bomb. Also, due to the effects of magic on electronics, pretty much everything other than kinetic impactors would be fried by any kind of spell that manages to connect.
We’re never shown really bad stuff, and during a discussion in MoR it’s mentioned that thermonuclear weapons are only a bit worse than most really bad spells, and that Atlantis was erased from time.
Good points, all. Fiendfyre seems robust.
I might counter that most combat magic, even the adult sort, seems to be line-of-sight, which is a huge handicap. It also seems to be very inaccurate. If Harry & Co can literally dodge Deatheaters on foot and brooms, supersonic jets and HALO insertions are going to be really hard to target. Not to mention artillery shells in flight. And Wizards seem weirdly resistant to (biased against?) using magical heavy weapons or fire team tactics. They have a real duelist mentality.
But the ability to erase from time does really trump. I concede.
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 97. 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.
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, 25.
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:
