My dad was just talking to me about his experiences going to school and college in the 70s and, while he learned to use FORTRAN on a time-shared mainframe, programming or computer science as a career path wasn't advertised to him as a possible career path. Most administrators and guidance counselors at the time probably didn't understand those fields yet. Might have been different if my dad went to Berkeley, but it would not surprise me if most of the education didn't see programming as "real" yet.
Heck, the web was almost brand new when I was in elementary school, and there was only one teacher who decided to take the initiative and teach kids HTML. He wasn't even my normal teacher, and I think I kind of just got pulled into it for some reason. In any case, I carried those skills he taught me all the way into adulthood, and I'm a web developer today! If he didn't host that class, I might not have ever bothered learning about Web technology. Otherwise, it wasn't like computer skills were part of the curriculum beyond learning to type.
