I took CS classes back in the early 90s and again just recently. Back in the 90s, I remember learning about CPU registers; text, stack, and heap memory; pointers; algorithms; etc. The classes I've taken recently were focused on language syntax; REPLs; IDEs; and frameworks. It seems there has definitely been a shift towards the simple during the last 25 years.
