Had this written up for PM, but since it's public I may as well make my voice a touch louder.

I got to the third paragraph and lost my composure. I'm just gonna take it you [i]aren't[/i] employed in any area which uses quantum mechanics, information theory, or other rather abstract sciences, but you took some introductory courses and, upon reaching a state of mindblown amazement, attempted to apply quantum phenomena to everyday science.

Shit don't work that way, bro.

If it [i]did[/i], the human brain wouldn't function. It uses electric impulses, after all. Using your given numbers, there are presently approximately 1 billion users of magic in the world. Using your pseudoscience, that many conflicting viewpoints in such close contact would no doubt cause informational shockwaves large enough to affect living beings in most of the world. Not only that, but technology would likely never get to the printed circuit era, as electricity would NEVER have any rhyme or rhythm to its function.

But let's assume that somehow we got to present-day tech without magic preventing it. The anti-tech field would affect cities faaaaar more heavily than this school. A city with a million people would have over one hundred thousand mages, while presently it seems the school has, at max, a couple hundred (and I am being quite generous). That means no elevators, no transportation, no air conditioning, and lots of other things that'd make all the benefits of cities nonexistent.

Do note that I haven't even started on why the outright "science" of yours is wrong. Unteaching an introductory course used to excite youngsters into tomorrow's disillusioned scientific force isn't something I care to do online.
