"The debate in language acquisition is around the question of how much specific information about language is hard-wired into the brain of the infant and how much of the knowledge that infants acquire about language is something that can be explained by relatively general purpose learning systems," said James McClelland, a psychology professor at Stanford University in Palo Alto, California.
"In the past, people have tried to argue it wasn't possible for any machine to learn these things, and so it had to be hard-wired (in humans)," he said. "Those arguments, in my view, were not particularly well grounded."
I'm rather convinced that we now have the computer technology to start processing language better, it's just that no one has gotten to programming it yet. This is a step!
