Except, there is? Comprehensible input is how you've learned your native language, and how any human learns their first language(s). After all, you can't output (produce) what you haven't first learned (gotten as input).

What I really mean to say is that there's no strong evidence that CI is more efficient than other language learning methods. It is certainly a way to learn a language. But is it a good way to learn a language?

You are smarter than a baby and you can learn a language faster (e.g. with fewer hours of study) then a baby.
