Most languages with map/reduce don't have transducers (and they're certainly not central features). Also, don't forget that while Clojure is functional, it is also very much imperative (it's a functional-imperative language rather than a pure-functional language).

That's true but mostly irrelevant to the point that transducer usage isn't complex once one understands map/reduce, which are common, whether or not transducers are.
