How do children get adequate exposure – to different topics, advanced concepts and skills?

There are many sources of exposure for a child (and an adult) in open learning, specially given the vast and wide internet and media presence:
> Child’s own interest in any field leads the child to find out more.
> Interactions with parents, relatives, friends, neighbours and to all other people the child happens to meet. Thus it in itself is huge.
> Typically open learners travel a lot, both locally within their cities and also longer travels around the country and the world.
