The example was Torvalds building Linux. Linux was written before he attained a CS degree.

You'd have to have screwed up your life pretty bad to not have already learned to study and learn before reaching the point of going to a place of higher learning. But that wasn't a problem for Torvalds anyway. It is well known that he was writing software since he was around 11 years old. He is unquestionably self-taught, as the term is normally used.
Higher education is about gaining access to machinery that mere mortals can't afford on their own. Linus' university story is significant because that was where he was first able to use Unix. It is unlikely that Linux would have come to be without that experience.
But that is also the contention around a modern CS degree. What is the "Unix" of our time that you can't reasonably access without going to university?
