This helps the child develop emotionally and intelectually. The same is true of college students. When a new student comes to a university, they learn to interact, thrive on their own, and develop their own lifestyles. College students live in a mature, yet not all together grown up atmosphere with their peers. This helps the student develop their own interests and talents away from home, and away from the restrictions of parents and hometown limits.
College students learn to be their own people, and be responsible for themselves and their actions.
While the internet is a great tool, that is all it is, a tool. It is not the only tool that we need for success. For success, we need a combination of tools. It is clear to me that a lot would be lost by converting to an all digital learning system. I think that we need college campuses, and high school campuses, and all sorts of learning institutions.
