I second that curriculum organization is terrible in most schools. This became obvious when I was working on a mobile game. It involved a wide range of subjects from (obviously) programming, geometry, algebra, logic, design, etc. I imagine that if students had a project they would touch on many different subjects. This would be a lot more effective than learning subjects in a silo with no understanding of practical application.

Improving tactics towards the wrong strategy is better, but not best. Full stop replacement of some subjects with other subjects would make more "useful" people. If the goal isn't utility, any subject can be defended as being as valuable as any other subject, because they all have side benefits which they leach value from. Like the defense that video games improve hand eye coordination.
