Mutable state can be a huge time sink. It's why I'm putting more and more time into functional programming, since I think that Haskell (and Clojure) is closer to what programming in the future will be like. I think many programmers don't respect how much complexity is reduced when state isn't leaking all over the place. Of course there will always be times when you need state, but many times its worth jumping through a few hoops to make things work without state. EDIT: If programmers learn C so they can think lower level, they should learn Haskell so they can think in terms of side effects, composability, and the advantages of pure functions. Just a reminder, pure functions can be created in any language though some (Clojure, Haskell) enforce purity.
