But languages differ in how much of that they abstract away from you. If the language already does a lot of those algorithms and data structures with minimal syntax, the CS guy can think on an even higher level of abstraction.

There is not much more level abstraction than lambda calculus, logic, denotational semantics and similar though processes.

But I get your point of not having to deal with low level details.

You'd be surprised - there is an infinite hierarchy of abstractions above the primitive level you're talking about.
