I agree with this. Granted this is anecdotal evidence, but I recently graduated from college with a degree in computer science. In high school, I had no classes on computer science. I wouldn't even know where to start nor would I be able to model myself an educational framework to understand computer science as well as college taught me. Now even though high school taught me the framework required to learn a new skill, I just feel that my total unfamiliarity and lack of peers or educators would have made the task especially daunting.
