An important aspect of education is that it's remembered, in general.

I don't know about that. An alternate viewpoint is that education is just training for your mind and the subject matter doesn't matter much, then or later. Note that "education" is different from "professional training".

I vaguely recall that in 10 years most people remember pretty much nothing out of whatever they were taught in college. You can interpret this factoid in multiple ways, of course.
