What's the point with that quite lackluster story in Endwalker?

[Sicno]

I’m reiterating my point. Do you’d disagree with it? If not then there was no reason to begin this back and forth and we just wasted both of our times.

But your point is...

…that you can’t get rid of him and slot in another before or during the Final Days?? That’s the whole point for why Venat couldn’t simply tell everyone before hand remember?

But we don't have a timeframe for how long it took after Ktisis for the Final Days to start happening. So why are you fixated on it having to be super fast and nobody else could have acquired that knowledge in that given time? Also, as I said before, Hermes's kowledge is not only his own. When someone else passes their knowledge onto you you don't have to go back and re-invent the wheel on your own. These other scholars could have put their knowledge together and worked from there. And again, in a more serious capacity, full time.

And a reminder: the Scions didn't know a damn thing about dynamis other than it being the energy of emotions, but once they stepped in Ultima Thule their "expertise" was enough to create bridges and teleporters and even an entire zone. Having a low aetherial density to be able to manipulate it is one thing, having the knowledge of what the hell you're doing is a different story. Apparently it doesn't take that much.

But this is a contradiction. Once again, if she believed humanity unfit to live on, why would she believe that the sundered would be different if it did not at all change their fundamental nature. The point of the Sundering was to imprison Zodiark and in turn force humanity to face suffering head on. It was not intended to alter its fundamental nature. In other words, she believed in mankind’s ability to “find a way forward,” and the Sundering was done to force them to do so.

To be honest I think the real "merit" of why the sundered could where the unsundered couldn't is that we happened to have someone who was at the right place at the right time, who didn't get their memories wiped and who was willing to talk about it. Our fitness to manipulate dynamis would have meant nothing if we didn't even know it exists nor that Meteion exists either. We would have kept flailing our arms at the unknown just like the ancients.

So in the end the sundered's biggest merit was inventing time travel. And why did they invent it? Because they couldn't cope up with their own loss and suffering so they wanted to send someone back in time to revert things to how they once were. Wow, the means are different but that sounds awfully familiar, doesn't it? Weren't you saying someone did their thing in part because humanity couldn't move forward?

It’d be the same as someone making 14 exact copies of myself, all based on the person I was at that exact moment. Which means philosophically they’re are a million different answers to your questions. Personally, my thought is they are all me, until the first moment passes and we then have separate experiences, paths, memories, etc.

And I think after that "first moment" passes whatever is left of the original person ceases to be, and all these 14 copies start a new life.

None of the solutions mentioned would work given what we know of Dynamis and the nature of Ultima Thule.

Why not? The Scions taking an overdose of stupid pills and becoming sock puppets for some stupid emotional manipulation bs the writer wanted to pull doesn't mean whatever they ended up doing was the only way forward. Honestly they didn't try anything else, not seriously at least. So that doesn't outrule any of the possibilities I mentioned.

And simply convincing a handful of Ancients to rough it doesn’t prepare them to face despair incarnate, a being that instilled a fear of death and suffering the Ancients never forget even after millennia of reincarnations.

I'm confused at what you mean, I guess you're referring to the part about grabing a spade and living a simple life, in which case they don't have risk of succumbing to despair because Meteion couldn't affect their bodies due to their aetherial density, only their creation magics. Stop using those magics and she has no power over you.
