Where is the existing evidence? And what evidence in modern science can possibly look into the future and make a prediction about something that right now is so far beyond our grasp? Statistical learning explains a lot. I'm a huge fan of it. Skinner's Behaviourism also explained a lot in psychology. But, just as in the case of behaviourism, I fear that statistical learning has/will hit a wall at which its explanations become futile and overly simplified. My personal belief is that, at that wall, we'll see that human language instincts and evolved language-specific mechanisms will be what we are looking for.
