A lot of things had been changed since that technology arrived, especially about online education. People who can not go to school for several reasons can watch their class at their home and it is a main reason why people believe that the current system of teachers and students in the class will not exist in some years, although I believe that is not true. In my opinion, class with students and teachers will keep forever or at least for longs decades. Following above I will explain justification.
Class between students and teachers always exists since old times when only boys was available to be part of education. Nowadays, both girls and boys has access to do it and through school they can desenvolve their knowledge and social life. Being in group with different type of people can improve culture of diversity population. In additional, they will learning to be respectful with one another and empathy with other students, as sharing a toy or huge someone that felt down on the floor.
