The biggest problem of functional languages is that they teach things of doing things that are not how computers work internally. For that C is much better. Assembly language the best. Or any other procedural language will teach you more about how computers run under the hood. Recursion is a purely math concept, in real life the chips don't work with recursion, they work strictly with if-then (more current/less current) logic. Assembly language is also procedural. Also, there is another fundamental thing that is a blocker for functional programming - our brain. For recursion you have to keep in brain many things while you call yourself. This is extremely hard (hmm, I wonder why the Lisp Machine was so pricey ;) ) - especially for the majority of people whose brain has problem to remember more than 2 things in the span of 5 seconds. If you like math, yeah, sure use Haskell or Clojure, but for the most people it's an overkill and for the most part people still tend to write very procedural code - you have for loops in Clojure - I am wondering why ;D I like some things that are often associated with functional programming, e.g. immutability, but I am not a fan of recursion at all. Also there seem to be some obsession of having dynamic types in many Lisp and functional programming languages, for example Clojure or Elixir, and I hate it.
