People not just children need supervision and guidance when it comes to information going into their heads. It is why whichever culture you pick across the globe, "education" involves having a "teacher" figure around. There is no system anywhere where you can just drop of the kid at the library and magic happens.

Take this community, you will find the ones that are good at what they do aren't just good, because of access to information, but because of the kind of mentors that have been around them or they have run into in life.

That's really the missing piece in today's internet. Despite all this information access it's still hit or miss that a kid or an adult will find the right mentor.
