【简答题】
We often hear about the “generation gap” that occurs between parents and children when it comes to music, morals, fashion and a host of other things. Now there is a generation lap, the tendency for young people to be increasingly more technically savvy than their parents or elders. This gap exists in the use of technology where the young generation has become the authority, effectively flipping the typical parental and professional hierarchy on its head in many respects. The implications are huge. Family members begin to respect each other for what their authorities actually are. This insight can be extended to social institutions, as well. For example, in Finland 5,000 N-Geners have been chosen to train the country's teachers in computers. For the first time ever, the students will be the teachers and the teachers will be the students.
