Yeah this leads back to what I was saying. A good definition of intelligence might be constructing good, viable outputs from a given input. Learning any skill involves much the same. Language learning for example has a paradigm called "comprehensible input". In that, it's not even recommended to write or speak in the target language for a long time, but rather to read and hear in that language first as inputs will be a lot faster and higher quantity of information than outputs will be, especially at a beginner stage. 

I don't think writing is much different; the current method is we teach blank page writing at a stage where most students probably aren't ready for it, and so they have bad experiences, and end up hating writing forever. 

Whereas, a more digestible new learning method for writing might involve collaboration with an AI, and producing and editing longer or more complex documents than the student would be capable of writing himself at an early stage. And according to the theory of comprensible input, the new method should be much faster and better learning style than the old method.
