They also had to rebuild the Aetherytes, so the current ones we ahve are not the original ones from 1.0, which were destroyed by megaflare.

We are currently using technology funded by Ul'dah to teleport around, which is why the natural aetheric gates no longer exist.

There was a lore post by Fernhalwes about this somewhere.
