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

Here’s my thinking though. Let’s say they would eventually prove to be their own undoing or even went the way of the plenty. So what? They’ve lived for what seems to be hundreds of thousands of years. If they did all die off eventually the planet would give birth to new life. That’s why Meteion and Hermes’ thinking is flawed though. You can’t go into life thinking well they’re just going to die anyways. Every single civilization will fall at some point. But that’s not what matters at all. Because then we can just apply the same logic to the sundered and what they should all die too? I really don’t think the devs thought about their themes and messages so much tbh. Especially with just how much they conflict with previous ff games’ themes.

Civilizational fuck ups rarely result in the end of the world though, and the Ancients were uniquely qualified to do that. Heck, they created something that could literally end the universe, which is truly unique to them, even including what we saw in Ultima Thule. It wasn't a matter of "these guys will eventually die," it was "these guys will eventually die and could take quite literally everything in existence along with them."

The Ancient's society was already built in such a way as to manage the likes of Venat and Hermes. It just so happens that the writers decided to stack numerous strange plot devices on top of each other as well as ridding numerous characters of any agency or sensible behaviour in order to brute force through a very specific outcome.

It was Shadowbringers that showed us that all it took to end the world was 14 Ancients in a trench coat (or however many people were in Venat's faction). Nothing about their society suggested that they could do anything to stop that.

This wasn't Venat's fear though. She specifically was afraid Etheirys would go the way of The Plenty, which is the antithesis of another subversive agent as they had achieved "perfect unity".

That just means she was a symptom of the problem she was trying to solve. That's precisely what makes her a hypocrite.
