That's programming. I'm hoping these CS videos are more about data structures, algorithms, theory of computation, introduction to machine learning, language compilation, etc.
I never realized before how well a Reddit style conversation could work as a lecture format. Very short "lecture" part, then lots of comments with people trying different things, asking questions, and getting answers both from their peers and the "lecturer". Very simple, but very effective.
I don't find either of these to be very similar to Khan. My favorite things about Khan are the lengths and speed.
But "already done" comments are usually incorrect and short-sighted.
