I don't want to hide it at all.
Hiding it is how we have the current situation, where every society has to build up "how do I magic" from scratch, where people don't treat it as a field of study and instead treat it as just another variant of superhero's, where it's all about what an individual Magic user or artifact can do for you.
I say no.
We are a scientist, an academic, and knowledge should not be hidden from people.
The USA can pretend that magic isn't real and lie to their citizens and even convince people that it isn't real, but long term, it's actively detrimental to the world.
Magic isn't just one field of study, it's multiple fields of Science that the government is actively covering up. All of the things magic can do, all of the different types of it ... it's like if the government was covering up the fact that Chemistry, Physics, Geography, and specifically Gravity were all real things. More then that even. Magic is an entire facet of reality that the Government is covering up. It's like their hiding the fact that Space or Time exist.
School for magic, we call it a school for magic, try to get as many students to become teachers as we possibly can so we can open more schools of magic.
100-200 years from now, I want learning Alchemy as accessible to the average citizen as learning Chemistry, degrees in Evocation should be just as obtainable as a degree in Art History. ESPN is boring, I want MESPN, with the M standing for Magic, where they play Magic Baseball and race on broomsticks and Magic Carpets.
Hiding it is how we have the current status quo, whereh there's normal society, and magic society, and the two stay completely separate and neither ever helps the other. I say BOO to that, integrate it.
