In my opinion, The disadvantage is that the robotic teachers. First, some may not understand the mood of the students. The second priority is to control the students in the room was empty or not thorough. Further, it is not able to answer questions that students do not understand or do not take care of every student. This may be exciting at first. The last time, the story may be boring for students.
