PE, French. I’m sure understanding a bit about computer graphics is at least as useful to the average person as the quadratic formula.

Is that an argument for making 3D graphics mandatory or the opposite?

I am suspicious of arguments of the form: “Here’s some stupid shit people do! Let’s do more.” Although I will grant there is a seductive consistency to the logic.

It’s not an argument for or against anything other than saying it’s no more or less absurd than having compulsory classes in badminton or years of a single foreign language

There are of course more generic ways to use the time to teach in that area — teach person so finance instead of quadratic equations, teach a wide selection of introduction to language and importantly culture from a variety of places around the world instead of a single foreign language for years on end, teach personal health instead of whatever PE is, teach more generic computer concepts (what a file is, what a network is, some form of programming) rather than specific tools (be it blender or powerpoint)

But we don’t do that

I think it's nice to learn a bit of many things. It gives you a better idea about what you want to do after graduation.
