I kind of wonder if this research would translate to _programming_ languages at all.
But that's a guess on top of a guess, so grain of salt and all.
Learning a human language uses a part of the brain which has evolved for that purpose. It not only requires learning thousands of words, and mapping them to concepts, but also learning how they fit together (syntax) and change (morphology). And this needs to be done in real time, both recognition and production.
