Number 2: (from my daughter, Francesca)We learn C because understanding how the computer manages memory is a fundamental part of CS. In C you can't avoid understanding if things are allocated on the heap or the stack, if you pass things by pointer or by reference. Yes there are languages that let you avoid that, but it's important to have a fundamental understanding of what the language you're using is hiding so you know how to use it well.
Similarly understanding how data structures work by building them by hand is important so that you understand the fundamentals of the performance tradeoffs between them.
In racket you're learning the fundamentals of recursion, and recursive data structures. Everything in racket is functions, and data structures that are defined in terms of themselves, e.g., linked lists, and trees. Recursively defined data structures and recursion more generally are fundamental to computer science.
