I have contributed to one of the projects he originally authored, and my mundane contributions along with other volunteers not as brilliant as him have ensured the continued success of the project. I'm with gp: teams ship software, not individuals. Individuals may ship bug-fixes or largish features, but for software in the large, that is the realm of teams.
I've been there & done that: I've been the person that crunches and turns around impossible situations, and I have also spent months cleaning up after a 10x engineer who shipped a feature in "record time" that made the company lots of money but caused countless support calls and bugfixes for months on end until it stabilized. Many so-called 10x aren't, and rely a lot on a supporting cast of regulars to enable their "outstanding" work
