Modern vs Medieval, what time is it?

[Edax]

So, we do know that the world is essentially in a Simpsons time bubble and the only definite movement is from 1.0 to 2.0. However, recently I've been questioning what exactly are the times.

As in, is Eorzea still primitive or is it safe to assume your average Ul'dah merchant wouldn't balk at a gun, concept of a hot shower and could operate a tomestone of frivolity?

tl;dr incoming

You have job quests that show that formerly exclusive job paths are becoming more and more open to the masses, seasonal events which are very modern and out of the norm (See casually coddling and parading a voidsent for All Saint's Wake) but then snap back to the MSQ. The snazzy leather jackets, jeans and 20th century fashion go poof with turbans, tunics and whatever era you'd call Ala Mhigan fashion.

From mass production of guns back to sticks and rocks.

Interior design is also harder to place since we can't go into every building the way we could in ARR. Sinks are a housing item, toilets are actually coming soon, and other indoor plumbing. Do they have this stuff in Gridania too or are people respecting the elementals with free "fertilizer."

Saying all this to sate my curiosity on the state of the world on the Source. A lot has happened since 2.0, and as the expansions go on, I'd like a more clear understanding on what constitutes as the norm or standard in a world where a chocobo carriage can slowly carry on, and then vroom vroom two Adventurers are doing sick donuts in a Regalia and SDS Fenrir.

I would term it "post-modern age collapse" as a parallel to the bronze age collapse. There was a modern era Allagan empire but it collapsed in a calamity regressing the people back into an Iron Age. The modern technology of Allag is still around in pieces and can be used but not readily copied so I would say currently the Source is progressed between the Medieval Age and the Industrial Age depending on what civilization we're talking about and how much Allagan technology they've reversed engineered.
