Education systems in XIV

[Lyth]

It's difficult to make any sort of comment on exactly how much knowledge has been permanently lost as opposed to temporarily lost, because that's entirely writer discretion. Allag's computer systems and genetic technology are certainly not part of our mainstream knowledge base, despite G'raha's access to the (non-password protected) sections of their databases. If we really were entirely reliant on Allag to get to where we are now, then we would be making same technology everywhere. There will be plenty of cases of reinventing the wheel in the interim as we learn more about their discoveries.

It's also really difficult to appropriately credit these discoveries and trace the flow of information between civilizations. For example, the Garleans managed to reverse engineer and even improve on Allag's original warmachina with the addition of a synthetic auracite system as part of the Weapons project. But the idea of using auracite to store primal energies is not even an Allagan concept. It dates back to the fall of the Thirteenth, and has ties to Ivalice and the Lucavi as well. Figuring out how exactly the cross-pollination of ideas occurred between all these societies is going to be entirely speculation at this point.

It's difficult to make any sort of comment

I don't think it's as difficult as you're making it out to be. The Allagan Empire was a world wide empire. It had a hand in every cookie jar. There's organizations and individuals in every society that pursue technology and trinkets from their civilization.

Every big technological "innovation" in the present of the game's world was brought about by organizations versed in Allag. Most prominently, the wide reaching Garlean Empire which passes on Magitek technology either through conquest or from having it stolen from them. I mean, just where do you think Carvallain got his ship's ceruleum engine? You know, the one that drastically cuts the voyage time to and from the Far East.

Another big piece of truly ancient technology that has survived into the modern day is the aethereyte. Which we've known to be part of Ancient society since Shadowbringers. World wide teleportation networks for any capable of teleportation. If that doesn't give every society afterwards a leg up, then nothing does.

Like, sure, we can't trace a line between every piece of knowledge from then to now, but there's plenty of instances similar to Buckler Stew that we can.

The short of it is that we're actually in a post-post apocalyptic setting where anything new can be old again.
