Well, Unix including the C programming language were essentially implemented by two guys (Thompson und Ritchie); at least in the beginning Unix was small enough to "be understood in its entirety by a single human being within one lifetime". The same applies to Linux (implemented by only one guy in the beginning). Also the Oberon System (written by Wirth and Gutknecht) became bigger and more complex during the years it was used at ETH; barely anyone has full detail knowledge of e.g. the whole Oberon System V4. We can assume that if the Oberon System had been more successful, it would have shared the fate of original Unix and Linux, and became too big to be understood in its entierty by a single person.
