With their Kama, that's not exactly "expendable" in the normal manner; they would just resurrect after a few years. However, the system responsible for that is exactly what is damaged.
(It's always start with Naruto and die off before you get past the Chunin Exams...)
Yes? But so far we've seen nothing connecting this to anything other than MGLN, and the multiverse is vast so for all we know the Ōtsutsuki are surrounded by worlds that don't stand a chance against them. I mean sure they'll eventually bump into someone, but so far it hasn't happened.
The thing is that they haven't prevented it from spreading. They have no reason to believe that this is just a network phenomenon, and in their favor it doesn't particularly seem like they do make that assumption. But they're not doing anything to address the origin of the problem. And that's probably usually safe for a house fire in the real world, at least for long enough for it to stop burning. Most ignition sources are local and immobile.
Except as mentioned before Shihiki did at least look at the Power Nodes and saw that they were 'unusually active', he assumed that means Kaguya is on ground containing things. So he contains the Network damage and salvages things there, because losing that would be bad for all of them, while Kaguya who is already considered expendable contains things on the ground hopefully long enough for him to fix the Network and for someone to get freed up so he can send them to investigate.
To use your example, it is a nest of fantasy salamanders, but there is ALREADY an adventurer there handling the situation. One high-level enough that, as far as the guild knows, they should be able to deal with it. So they are marking the area "salamanders here, do not enter" and will come back when the Adventurer is done, or dead.
Except that Creation of All Things isn't supposed be an issue of power. It is basically "are you able to perform the basic yin-yang release?" and "can you visualize what you want to create?". Sure, you can make supernatural effects with greater power, but if you can separate Yin and Yang, visualize an object, and smash the two chakra together, then you can do Creation of All Things.
I now have an amusing picture of Danzou in a spiral of stroke -> Izanagi -> stroke -> etc
Plus, of course, the "firebreak" for the salamanders to wander across is measured in light-years. He probably assumes that, even if it does start to spread, they have plenty of time to worry about it later.
We haven't seen a tome in Worm. We saw a damaged belt that became a necklace in Worm.
Where have we seen it in Brockton Bay?
He was talking about Hybrid Hive, CmptrWz's wednesday story.
I do not read that scene as "I trust Kaguya to deal with this".
Kaguya, who he doesn't consider reliable at all, vs. and unknown but known to be unprecedented problem?
Dude, the Otsutsuki literally have never met anything more powerful than them. Kaguya is a WEAK member of the species and still supposed to be able to handle basically anything given enough time, which their natural agelessness and reincarnation techniques grant. Their thought is basically "if it exists, it is weaker than us", and reality has basically shown that as true. Just because the uber-powerful race sent the weakest member, doesn't mean that the weakest member isn't strong enough to handle the issue.
This came from the actual chapter:
The viewpoint is absolutely not considering it a certainty that Kaguya has this handled.
Having it handled, and having it contained aren't exactly the same though. So long as Kaguya is fighting it, that means it's probably focusing on her and not them. I mean really what is Shihiki supposed to do? All of the Clan are focused on their goals, they're focusing on harvesting what worlds they've planted trees at for now. And he doesn't have anyone to spare because even those who are considered expendable have a job to do right now, and they don't have the time to go out to a far away isolated area to investigate right now.
Right.
Arrogance is a hell of a drug, Pride too now that I think about it. Something all Ōtsutsuki even the Moon ones have in vast quantities, when you fit the definition of a immortal 'living god' lowercase g in this case, and have ambitions and plans to become living Gods with the uppercase G you kind of need them. Combine that with a feeling of security in 'We've crushed all who opposed us in the past, we can do so again. Especially when we ascend to divinity.' it kind of lines up with what you'd expect.
