Despite the fact that most of the world is now connected with high-speed fiber and even phones can record 4k video, it seems to me that there is a large focus on offline events. Universities invite guest speakers, hold seminars, organize conferences, etc, and most of the content is not even posted online afterwards. Often the events themselves don't include anything more than the speakers doing their presentations, answering a few simple questions and leaving shortly afterwards - all of which could be done on Skype or a myriad of other platforms.
So why is there still such a strong focus on physical presence?
