That's not true; he did experience the traditional university, but that's really not what he said how it should be taught

By teaching differently (what he calls systematic debugging): figure out why students fail to grasp a concept, and fill in whatever gap of knowledge is causing it. Teach how to self-perform this process. Instead of throwing in the towel and say they won't hack their way through the rest of the course i.e. the traditional university way.
