Language as an extension to the mind
This is an interesting idea.
This article and most comments seem to be thinking from a context of "individual." A fuller notion of language includes the exchange of information among individuals. Perhaps evolution may develop along the lines of "group think" (as in two heads are better then one) as contrasted with trying to develop individual superstars of thinking.
I think humanity has barely scratched the surface of possibility with what deep and prolonged truly collaborative engagement might enable. Hell, if we could all simply work together toward our collective best and long-term interests, we might not even need super powered individual brains in the first place. And as we live in a more harmonious environment and can devote more resources to creating more engaging and hospitable environments for the development of our young, our higher brian functions may reveal as yet unseen (or rarely seen) capacities that might be all but invisible from our brains as they develop in a world such as ours.
