As mentioned, repeatedly, the understanding of magic has advanced to the point where the arcane is a fact of day-to-day life. Instead of being taught in colleges as part of a rigorous lifelong study, the basics of magic can be picked up by hobbyists as easily as Earth students pick up basic electronics - even some grade schoolers can learn a cantrip or two. However, just as electrical engineers can build items from scratch whereas your average grade schooler is more of an amateur hobbyist, true magical talent must be cultivated, but the ability to fake it is available with assemblable kits and factory-made goods. Many people use magic in their day to day lives without having much idea of how it works.
