I don't understand. A self-taught programmer would know everything he needs to know given that he learnt with the right resources. Whatever you can learn from a teacher you can learn it from a book; teachers themselves write the books! The only difference would be that you can't ask question to a book, and if you have the right questions, that's invaluable. Good thing we have forums and stackoverflow, but sometimes questions don't get answer and when they do, they don't get a quality answer for that matter.
To add to this, I wonder how much better sitting in a lecture hall listening to a professor explain something actually is than watching a recording of that same lecture.
