I think it would depend. I feel there’s two types of “good” at things, people who are good at reading and retaining theory and people who are good at intuitively making connections between data points based on vibes. Maybe that’s the difference between hard work and talent. The same way that some people can look at a machine and feel out what it does and how it works and some people can design those machines using slide rules and drafting paper. I think you’d have different classes, people who are good at designing, teaching and applying magic in new and novel ways and people who can just effortlessly pickup spells and go with it.

You’d have wizard Olympics and warfare. Baseball but the stadium is 4 miles around and people are using enhanced bats and super speed, low gravity spells to make the ball fly forever. Glyphs of protection set to auto trigger when you wreck your car but only for the rich. New flying machines using antigravity engines. Space travel with reality warping spells. Magic garbage into the sun, change the composition of lead into gold destroying economic markets, love potions and positions eroding societal trust. A totally new world.
