Came up with an idea of a method to ressurrect Hermione.
Brute force method:
Discover secrets of Atlantis, hack time travel, etc.
The problem with this is that time can adjust to avoid the paradox at any point in the timeline, which means that if you are a person who would try to exploit this, the sperm that would have created you was outraced by another one. So perhaps existing depends on not using this. (Parfit's Hitchhiker)
Or, if you try to use this and commit to be really serious about it, you get struck by a meteorite before completing the paradox. Or slip on a banana peel and bash your head. Or a get mauled by a troll. Some external cause comes in and prevents you from fulfilling your paradox.
Or you never come up with the idea in the first place.
Or abiogenesis never happened in the first place. That seems a lot simpler than nudging tons of different humans later.
Do you know, for some reason that actually strikes me as more terrifying than the fabric of time-space collapsing. Which is incredibly human-centric, since it prioritizes the existence of humanity over the extinction of every species in the universe, and yet is true nevertheless.
I will have to think on this.
DO NOT MESS WITH TIME
That method would resurrect something but not the real Hermione.
Really? That method seems almost identical to uploading Hermione.
In our world Tulpas are mental entities that are somehow self aware.
If you create a Tupla inside your head that's modeled on your friend Alice that died, I wouldn't say that you have ressurected Alice. You have a thoughtform in your head that behaves like you think Alice would behave but it's no real Alice. It's not as good as a real upload.
The second bit does not accurately distinguish between a frys-njner ragvgl naq n aba-frys-njner ragvgl gung whfg vf "cebtenzzrq" jvgu gur erfcbafr bs "lrf" gb "ner lbh frys njner?". Hayrff lbh ner vzcylvat gung fbzrubj nfxvat gur dhrfgvba jvyy znxr gur cnvagvat orpbzr frys-njner fbzrubj?
