Widespread two-way telecommunications also allows many students to learn from exceptional teachers who might be located in quite different geographical areas. The focus of any education is to be able to do something with it. Rather, any subject studied will immediately be turned into a practical activity and skill that one can practice freely. Children will learn math and science to build things they want to build, or to better understand activities they are engaged in. They will learn about different cultures as part of interacting with members of those cultures, either through remote communication or through visiting different regions.
Education is a life-long activity.
The world and its body of knowledge is changing rapidly, so there is little value in having attained a degree in a subject that is no longer relevant. Rather, the idea is to stay current with the knowledge or skills you need to perform the duties you choose in life.
