Probably because no one was spoon feeding you or holding your hand. Plus the fact that people who can teach themselves are probably a little more driven or competent to start with.

I would guess autodidactic learners are more likely to pick this up than those who mainly learn through formal education. I don't think stack traces or debuggers were ever really covered in my CS program.

Then again, neither was version control...

Then again neither were the languages you were expected to do your homework in. I think there was one "Pascal language" class no one in the Major took. The faculty cared about the Computer Science (Math) underpinnings; the language dejour was just a speed bump to help separate the wheat from the chaff.

My program had a pretty good layout as far as languages. I think the standard was 1.5 classes of C, 1.5 classes of Java, then pretty much everything after was in one of those languages.

Only time I felt students got shafted was a Web Dev elective. People who weren't already pretty experienced with JS had a really hard time (we were on the quarter system, an HTML/CSS/JS+React/Redux+Node is pretty ridiculous to cover in one quarter).
