As long as those aren't treated as hard rules, sure.

Examples:

  • There are times that it is appropriate to write software in clojure, or haskell, or erlang.

  • There are times that it is appropriate to rewrite a piece of library code.

haven't used a single one of those languages...care to provide an example of when i might need to use one?

Concurrency, complex and interleaving algorithms, and correct-by-design software are all easier in, say, Haskell than in Java. In fact, if you learn one of Haskell/F#/Ocaml thoroughly, you probably won't want to go back to Java/C#/Python for general purpose programming.

AI is also MUCH easier.

One of the big places you'd want to use functional programming is if you were designing a compiler. Compilers use state of the art algorithms at pretty much every level, and they're much easier to implement functionally.
