And in a way, it's true. As I wrote in Rebel Code five years ago:
Linus is unique because he was able to serve as a focal point for ... advances to come together to create a complete methodology that is now central to the continuing success of the open source movement and that offers the first plausible alternative to the current - and creaking model of software development. But Linus is also replaceable because of this methodology, which allows programming and architectural decisions to be relegated to specialised circles of experts; and thanks to this methodology even his leadership style - that of power wielded in subservience to the user base - can be distributed more widely.
