are colleges obsolete in digital age?

Answer 1

You can't ask questions to a tape recording, so no, teachers are not obsolete in the digital age.

Answer 2

Your premise is flawed, because you are assuming that education is the same thing as the parroting of facts.  The problem with this is that only a very limited amount of education today takes place by pure lecture.  We can all listen to people talk, just as we can read a book.  It doesn't make us educated.  People need to be guided through the process of interpreting the data so that it becomes information, and processing the information so that it becomes knowledge.  That is the role of a professor or teacher today, and no one great teacher has time to do this with each individual student out there.

Answer 3

Well, if a student just had to go find the broadcast on the internet then who's to say that they will?  And even if they do, who's going to explain all of the little things that aren't always easy to comprehend?  I mean there are just too many variables to just assume that a student can learn from a recorded lecture.  Teachers serve a great purpose in a sense that they are more knowledgeable than a little recording or broadcast.
