it may be possible that a programmer never has to implement something such basic on his own, but it's neccessary that he understands what's going on "under the hood", so if problems occur (and they usually will), he has a clue about how to solve them.

Right. The higher level abstractions provided by languages like Java and C# are useful, but you still need an understanding of what's going on underneath. Otherwise, how do you choose between structures like HashMap and TreeMap or ArrayList and LinkedList?

Surely, this is often considered "old-fashioned" or "unmodern" by many novice programmers who know how to click in "Visual BASIC" and consider themselves geniuses.

Except that today, the "disease" is carried by Java, and it's even worse because the whole thing has been institutionalized by the educational system. I don't blame Java itself-- it's a perfectly fine language if that's your cup of tea, but it is the current tool being used to train an army of programmers who are completely unable to see behind the abstraction.

But if you're just keen on a BA, MA, Dipl.-Inf. or some other degree that you can show around, while treating your PC as a worse typewriter, it should be sufficient. :-)

The only problem with this is that a Computer Science degree has become completely irrelevant as an indicator of someone's level of knowledge in the subject. Not that it was ever perfect, but it did, at one point, suggest some minimal training and understanding of the basic concepts.
