I’m not in CS, so maybe it’s different, but I don’t know how we can expect to get skilled biologists, mechanical engineers, psychologists, etc without something that’s very similar to the 4-year degree.
Edit: initially i said “ People bemoaned the loss of chalk-on-blackboard skills when paper and pencil got cheap”, but apparently that’s not true, it was first claimed in a piece of satire, and then became mistaken for the truth.
