I was going to reply, but ipython wrote it already, better. However, understanding his reply requires the ability to read it correctly. Notice that we are not having the hackernews discussions as a long list of small video clips. People who have not learned to read on a professional level, have a hard time grasping the volume, depth and speed with which you can transfer knowledge through text, using that developed skill. It is trivially true that a person who has not learned to read well, learns faster by watching videos. But this is not an argument for videos being the most capable mechanism, only the more initially accessible. You may be able to start running before I can saddle my horse, but once it is saddled, my horse will outrun your running start. There is obviously areas in which video, 3d and computer systems/models surpass what a book can present, but outside those areas, the information in the world belongs to books,or the computer equivalent thereof. It is not about old books. It is about that written text is our strongest tool yet to present and capture a large connected set of ideas into a consistent argument, and similarly to RECEIVE such an argument. If you think a youtube video will do 'just as well', you probably need to read some more books :-) At work, I dread whenever I have to develop software for which I cant find written documentation, but must rely on random youtube guides sketchily explaining bits of it like and subscribe.
