It depends on the audience, but I think you are largely correct. Computer graphics / demos / games are a seductive way to introduce linear algebra. Here's how you rotate a point on screen, using only numbers is way more interesting than solving linear equations.

That said, there is an audience for whom the beauty of the subject is enough. Now when I hear "Galois theory" or "Navier-Stokes" I just think "I don't know what that is, but I want it!"
