I didn't really get that impression from NTBS, but I did sorta get it in Waves Arisen, like when. But Waves Arisen is weird yet good in that it didn't strike me as well written, but looking back on it, it was a thoroughly rational work that realistically displayed the realities of ninja life like that - death is sudden, unexpected, and rarely preceeded by a dramatic last stand.two major characters die offscreen when they're poisoned in jail, with no buildup or warning
That's more elaborate than my interpretation, which was pretty much just agreeing with Kagome that chakra is something the sage made up for some purpose or another, via admin privs on a post-singularity singleton AI.
Seals fit in to that a bit weirdly, though. Would make sense for it to be from the same source, especially since it still involves chakra, but it still seems to be a separate thing. Maybe its sort of a exploit? But the whole separate paths, etc is very elaborate; if AI-theory is correct, those would probably be simulations that the AI shuttles summoner/summonees to and from. But why are those there? Those couldn't be the result of a simple unintentional exploit.
Its definitely all artificial; seals/chakra are clearly anthropocentric systems (and originate from such), and if they were natural features of the world extant since the beginning, things would look very very different. For one, evolution would probably have discovered sealing and either tiled over the universe or destroyed it. And much else. But the specifics are hazy.
We have WoG that seals are capable of doing anything jutsu is capable of doing which is literally anything.
@faflec : have fun tracking down that one. No keywords to help you here.
I believe that I have mentioned Ra before. We are in a supposedly rational universe which has magic in it instead of parsimonious derivatives. Therefore, there must be some sort of being of god-like power actively fucking with us which needs to be immediately slain before I get more angry.
