Could Face-to-Face be Phased Out?

As the dulcet tones of one of my university lecturers echoed through the corridor of my flat this afternoon, it dawned on me that personal contact isn't quite as important as it maybe once was. We (that being myself and 2 of my flatmates) had a lecture today that was replaced by a recorded lecture which was online. It was the same stuff that we would have been told had we all trudged over to the lecture theatre as our timetables tell us to but this week the lecturer in question was unable to attend and so made a digital version instead. It's a curiosity of the modern era that, in a time when we are told as youngsters to get away from the computer screen and become more sociable, we are being fed more and more information via the internet. Personally I like it because it adds a new level of flexibility to your day - something that I'm starting to feel is essential after only 3 days of 2nd year - but its long term affects could be perilous.
