no, as long as you don't think that a wand with some technology implemented to do stuff like that is the same as using a wand which is only some wood or metal without any hidden technology.

No, "magic" means physically impossible.
If we would invent something similar to the Harry Potter stuff it wouldn't be magic.

Think about Nikola Tesla and all the things he invented, all was like magic back in the day, some are like magic even today. Internet is like a huge mind pool of comunication, which is a very magical concept as well.
So, yes, the more we understand nature, the more life will look magic.
By the way, a Nuclear Explosion is very much a Final Fantasy Ultima Weapon if you think about it.

Maybe for amateurs, but experts understand what they're doing. There's nothing supernatural for them.

Damn you! Damn you all! 

AND POOOF .....

the dream is gone

"Any sufficiently advanced technology is indistinguishable from magic"

- Arthur C. Clarke

"At least at the time of writing"

I guess understand your point, but even though it looks a lot like magic, the simple fact that we created it would not qualify it as magic. but yes, we can someday conjure spells, but with a lot of science behind it, a lot.

Well, but that is the case for all magic. To those who pratice magic, it is a natural thing, the only supernatural stuff is what we do not understand.

I don´t think Gandalf says "Wow, that was spooky" everytime he casts a spell.

In the context of it´s lore, magicians do not do any unnatural stuff, they only manipulate very real (to them) aspects of nature, the creation and the Universe. Which is what science does in the real life too.
