People really underrate the difficulty of learning not a language but language itself. Concepts learned in one language can transfer over to other languages, but when you learn your first language, you have to learn the concepts for the first time in addition to the word. Personally, I am of the opinion that the critical period in learning is mostly a biproduce of learning over time and less a special feature of a brain’s age. The cortex naturally will organize around the incoming sensory information coming in, so over time the “increased plasticity” of newborn brains will reduce as it becomes increasingly more fitted to their experiences.
