Does technological advance have all the answers? NO. Each new technology is a mixed blessing. We should not become carried away on the sea of technological development and become oblivious to its hidden impacts. For me there is nothing that technology can do that can replace the intimacy of spending personal time with family or friends. Likewise in a classroom there is a huge benefit from social interaction between the teacher and the students that isn’t possible in distance learning. Technology can’t replace the physical experience of going to church with 500 other people, either, or the special times of personal prayer with God.
