Yep, everything newer is automatically better. No need to have any grounding in objective utility as long as you're up-to-date on the latest web framework!
> You might have an idea how a basic OS kernel works from your OS class, or how...or maybe...None of that is useful at all, other than maybe to get you interacting with your machine, in the hopes that you'll learn how to use a computer (which is a completely different set of knowledge)
Any decent computer science program is both theoretical and hands-on. Projects where you get hands-on experience with the concepts you just learned. Not all of us can read Data Structures and Algorithms and implement a search algorithm as an 18 year-old. No, not everyone needs to know this. Yet, some people do. For those people who do need to know, their work wouldn't be possible without it.
> If you go into your CS degree as a young hacker, adept at nix with a penchant for assembly language, with enough experience to appreciate the CS concepts, you're going to be disappointed. There's a strong chance that you'll know more than the professors.
True, but (especially now) I'd be surprised if this is <2-3% of the CS undergrad freshmen population. I personally switched from pre-med to CS as a junior in college with only a single QBasic high school class under my belt.
Finally, as others have pointed out, (and as much as I hate admitting to this phrase that was so often spouted out by my college professors, perhaps I have drank the Kool-Aid), you're learning how to learn. That is, you're practicing juggling abstract concepts in your head, making connections and weighing solutions. I found my CS classes were 10x better at making me a general problem solver than my pre-med classes (mostly my discrete math/logic classes).
