It doesn't help that early CS courses cover stupid examples like a recursive implementation of fibbonacci when the obvious solution is a loop. Tail call optimization is also another thing that should be reconsidered. Plain imperative structured code is usually the cleanest and easiest to understand. Introducing abstraction too early I think confuses people and encourages complexity where it's not needed.
