According to Dr. Pankaj Singhm, director of Nims University, "distance learning benefits may outweigh the disadvantages for students in such a technology-driven society; however, before indulging into the use of educational technology a few more disadvantages should be considered." He describes that over multiple years, "all of the obstacles have been overcome and the world environment for distance education continues to improve." Dr. Pankaj Singhm also claims there is a debate to distance education stating, "due to a lack of direct face-to-face social interaction. However, as more people become used to personal and social interaction online (for example dating, chat rooms, shopping, or blogging), it is becoming easier for learners to both project themselves and socializes with others. This is an obstacle that has dissipated."
