'oh no, a world that focus on magic doesn't have as much advancement in science as ours, unbelibable'
It's not like there's no real world examples of cultural difference, right? Totally every single human country develop in the exact same direction, the same way, regardless of their environment right?
There's no such thing as 3rd world country anymore, because we're totally technologically advanced as a civilization right?
Well, from the tone of your post I think it's pretty clear you're not actually looking for any kind of discussion here, lmao. But yeah, go ahead and misrepresent my post as "yes every society must be exactly the same" if you want, I guess. Acknowledging that scientific advancements
tend to help knowledge in other fields, and that there should be some rudimentary knowledge of the natural world for a society that's shown to otherwise be technologically equivalent to medival europe, is not the same thing as saying "all societies are the same". I don't even know where the part of your post about third world countries came from, because the advancement rate of separate societies and the advancement of disciplines within a single society are entirely different things.
Heck, looking back at it, Foa even says "certainly, the magic she uses is like a miniature version of the actual phenomenon", meaning it isn't even something they don't know, because he's able to confirm that it matches the science. That's even worse than I thought initially, because it's not even that they don't know about the water cycle, but that they
do, and nobody thought to ever try to emulate the water cycle with water magic until Aoi said "hey why don't you try to do it with magic" with no further explanation? Really? That just feels ridiculous.
