The one class I took in college that was relevant to my job, at all, was the AI course on structured vector machines, which were irrelevant after two years. For most programs, correctness is a nice-to-have, forget speed or responsiveness or data structure choice.. and in production code, non-technical and constant factors override theoretical solutions. University computer science courses, on the whole, are quickly obsolete or obsolete to begin with, incompatible with software development as it's practiced, and are best reviewed in the week before seeking a new job to score well on leetcode. The best skills you're going to learn are the metacognition you're picking up in university, the ability to learn new languages and adapt to new environments and solve new problems, not anything that's actually taught.

> What will happen when they get a technical interview? I can’t imagine them doing anything beyond answering phones at a company’s IT Help Desk.

My experience says you'd be very surprised. As in most fields, networking, charisma, and ability to bullshit play a substantial role in IT hiring.

> I listen to every word the professors say as if they’re telling me the secret to eternal life while half the class is dozing off.

This is absolutely brilliant.
