As an introvert, a remote worker full time, and a traditional BS in CS from a state university, I am more and more convinced the needs of many for "face time" is just because anyone over the age of ~20-25 grew up without ubiquitous communication without faces.
I'd cite my brother (age 12) and his generation, who seem to have no problem basically never seeing their peers from class anymore, but will play video games with them endlessly online. During summer break last year he barely went outside, besides what physical activity his mother compelled him to, which was not very much different from what I did, the difference being that his entire peer group is behaving the same way and from my impressions by him it is the norm rather than the exception now.
I fully expect that generation to have no issue doing collaborative learning using MOOC resources and the Internet instead of brick and mortar buildings in front of lecture podiums. Throughout history we have learned many a time how adaptable the human psyche is to its environment, and how much of ones assumptions on human behavior can be challenged and changed by the world changing around them. I think this is another one of those cases - because articles like this one are talking about college ten years from now, for children born ten years later. And that makes a huge difference in the Internet age.
