I found the comment about holograms interesting. Over 20 years ago I was involved in distance education using video tapes as the primary medium and the tapes were of the professor teaching the lecture behind the podium. We all theorized one day there would be holograms in your home or work that would off on-demand lectures and it appears we are almost there. I agree with Carolyn Farrell that hybrid is a better learning option than strictly online, especially for those hands on programs such as nursing, IT labs, and aviation maintenance.
