Your commennt exudes a particularly unpleasent pretentious tone.

The average software engineer does not need to remember compiler design, digital logic, esoteric datastructures etc to do their job well. If people are forgetting "fundementals" (of which I would not classify specialised subjects such as compiler design), then it's because they don't need it for the job they're doing.

Although I do agree that Computer Science theory is definitely important and knowing it is better than not. Sometimes a project your working on would benefit from knowledge of datastructures, cache locality, etc, and that makes the years of academia worth it.
